Abstract
The Australian continent has the highest solar radiation per square metre in the world
yet Australia’s solar energy production lags behind the global proportional contribution. As
of 2014 Australia’s renewable energy accounted for less than 14 per cent of annual electricity
generation and of this amount just 0.4 per cent was attributable to large-scale solar power
generation. At the same time, the cost of solar power generation has become more
competitive than other renewable and non-renewable alternatives. Hence there is significant
growth potential for solar energy production in Australia. Large-scale solar growth will
require the selection of appropriate sites for projects, yet it is difficult to identify locations for
large-scale systems since multiple criteria must be met. This paper explains why grazing land
is likely to meet the relevant criteria and provides a landholder focused case study which
evaluates the potential implicaitons of solar leasing. An ex ante cost-benefit analysis of a
solar lease as an alternative and passive income source for cattle graziers is used to identify
the economic value for doing so. Results indicate that in most circumstances a solar lease is
able to provide a secure income source to landholders that can generate more value than
existing enterprises. When the influence of a drought is considered, the relative value of a
solar lease increases. The social benefits of solar leasing are described with reference to these
findings to provide Government policy recommendations.

Chapter 1: Introduction
1.1 Background and Motivation
It has been recognised that the current trend of energy supply is economically and
environmentally unsustainable by governments, businesses and individuals alike. In Asif and
Muneer (2007) a global energy study established that the current fossil fuel supply mix will face
many challenges: finite quantities, climate change and related environmental concerns, volatility of
fuel prices and geopolitical conflict. This knowledge has given rise to the recognition of renewable
energy sources as a means to secure energy supply and minimise social and private costs. As a
consequence renewable generation technologies have benefited from increased investment. Over
the past two decades hydro power and wind power have been able to provide the most efficient
electricity supply solutions around the world, meaning that they currently lead the renewable
resource generation mix. However, in the last five years solar energy has become just as
competitive, so investment into solar has rapidly increased. The energy efficiency of solar
technologies has quickly improved with recent developments in polysilicon thin-film and cadmium
telluride technologies and it is likely that efficiencies will continue to improve (Asif, 2007). This
identifies a significant opportunity for solar to contribute increasingly more electricity to the future
energy mix.
In Australia, solar energy contributes a relatively small portion of the nation’s total energy mix, yet
increased affordability and efficiency improvements indicate that solar will become a more
dominant energy source in the near future (Flannery, 2013). The two main types of solar
technologies which generate this energy are solar photovoltaic (PV) and solar thermal
(Concentrated Solar Power – CSP) technology. The Climate Council of Australia indicates that by
2050 solar energy is expected to provide 29% of Australia’s electricity needs, of which it is likely
that most growth will occur in the large-scale PV sector (Climate Council, 2015). Australian
households have invested heavily into rooftop PV systems. Over 1.4 million Australian households
have installed a PV system and over 2 million households use a solar thermal or PV system. On a
per capita basis, this means that Australia’s adoption of small-scale solar is greater than any other
country (Clean Energy Council, 2014). State and national government feed-in-tariffs, subsidies and
grants have encouraged this trend. By contrast there are only eight confirmed large-scale solar
projects developed or under development in Australia and there is significant potential for growth
in this area.
The development of large-scale systems requires the identification of suitable project sites. Criteria
to be met include proximity to transmission lines, solar irradiance, sunlight hours, slope, shading,
2
zoning restrictions, fire breaks, soil type, exposure to dust and general social acceptance. It is also
important to consider the opportunity cost of using land for alternative purposes. Similarly, the
social importance of preserving wildlife systems, maintaining biodiversity and reducing other
negative externalities should be considered. The process of selecting a suitable site will be
identified in the following chapters, including an explanation of why grazing land is often suitable
for large-scale PV systems. This land can be particularly suitable for a solar alternative from a
landowner’s perspective when the low quality of existing resources limit returns from other
enterprises. This paper constructs a case study that addresses the potential for substitution of large-
scale solar with grazing land, and attempts to provide landholders with economic reasoning to
make enterprise choices in this arena.
1.2 Research questions & objectives
The ultimate goal of this dissertation is to determine whether it is beneficial for Australian
landowners (graziers) to engage with large-scale solar projects using solar lease agreements. This
involves an evaluation of the prevalence of solar in Australian at this time and an analysis of the
relevant benefits and costs to land owners. Therefore, using both primary and secondary data, this
study aims to answer what are the potential implications of solar farms for Australian cattle
graziers.
The first objective is to conduct a critical assessment of the global presence of solar technology
using secondary data sources provided by internationally recognised industry bodies. This
assessment focuses on the way Australia’s solar industry compares to those of other developed
economies and the aggregated averages for the rest of the world. The aim of this section is to show
that current reliance on solar energy as a fuel source is limited in Australia, particularly from large-
scale generation sources. Findings from this section are used to support economic analysis.
The second objective is to identify the potential value of a large-scale solar farm to a typical
Australian cattle grazing system and to an optimal grazing system using a hypothetical solar
project. By making relevant assumptions to describe a typical solar farm and the relevant grazing
systems, an ex ante analysis is conducted. A typical grazing operation for the chosen location is
used, covering 100ha. Similarly, 100ha of a highly productive benchmark grazing system is
described. Expected revenue streams and expenditures are expressed on a per hectare basis,
considering gross margin per hectare as a key variable. Cost-benefit analysis evaluates the potential
value of a 100ha solar farm against these two types of enterprises using income streams relevant to
a solar lease agreement. Revenue flows for cattle operations and solar leasing are projected and
3
discounted to a present value. The findings of this economic analysis are then used to describe the
situations in which a cattle grazing enterprise may be substituted with a solar farm to supplement
farm income.
1.3 Significance of research
This research is significant for two key reasons. Firstly, it identifies solar energy as an affordable
renewable energy alternative with significant potential to become a primary fuel source for
Australia. This is achieved by showing that Australia’s adoption of solar has been rapidly outpaced
by other developed economies, particularly for large-scale systems. This builds a framework to
determine how the country may invest in large-scale solar – by identifying suitable locations. An
assessment illustrates that grazing land is often suitable for such projects and ex ante economic
analysis shows landholders why it can be beneficial to explore the options of solar leasing. In doing
so cost-benefit analysis shows that when specific conditions are met landholders can utilise solar
leasing as a secure, passive income source which provides social and private benefits. These
findings may help solar developers identify landholder benefits so that they can build relationships
with landholders that enable the establishment of large-scale solar systems.
1.4 Outline of dissertation
The following chapter includes a literature review which contextualises global renewable energy
production trends, focusing on solar energy. Australia’s current use of solar energy is described
with reference to global solar energy trends. Australia’s solar industry is dissected between large
and small scale technologies. This highlights the current status of large-scale solar PV generation in
Australia and provides a platform for a case study analysis in Chapter 4. The third chapter explains
how data is constructed to facilitate financial analysis which can provide landowners with
economic reasoning to make enterprise decisions. Chapter 4 conducts an ex ante evaluation to
determine the private economic value of the described project under certain circumstances. In doing
so the analysis discounts future outcomes, providing relevant landowners with an estimation of
revenue streams over a 20 year period. This information is used in the final chapter to recommend
possible enterprise choices. The appropriateness of each choice is discussed, as are the implications
for policy makers.

Chapter 2: Background & Literature Review
2.1 Introduction
The purpose of this chapter is to conduct a critical assessment of existing literature to
identify current trends in the development of renewable energy. This assessment is used to identify
growth in the global solar PV industry. By establishing that future growth is likely to occur in the
large-scale PV sector in Australia the usefulness of this paper’s case study analysis is justified.
Renewable energy is broadly defined as energy which can be obtained from natural resources that
can be constantly replenished (Australian Renewable Energy Agency, 2015). A number of these
resources exist in abundance, which are classified by the following groups; bioenergy, geothermal
energy, hydropower, ocean energy, solar energy and wind energy. The prevalence of energy
conversion technologies for each resource is largely dependent upon the availability of the natural
resource and the cost of harnessing its energy. Economies of scale and technological advancements
have been realised throughout the renewable energy sector, enabling renewable technologies to
produce electricity at production costs competitive with fossil fuels (Climate Council, 2015).
Energy created from heat from the Sun or sunlight directly is known as solar energy. This energy
can be converted into electricity or be used directly for heating/cooling. The two main methods of
solar energy conversion are briefly explained in the following section.
2.2 Types of solar
Solar PV is the dominant solar technology in Australia. Using photovoltaic cells sunlight is
converted directly into electricity – sunlight energy strikes the semiconductor material contained
within the cell which triggers the release of electrons. Electrical conductors can be used to capture
the movement of electrons (electricity) (Knier, 2002). Common semiconductors used in the
marketplace are Crystalline Silicon and Cadmium Telluride. Multiple PV cells can be connected to
form a module and an array of modules can be used to construct a PV power system (Figure 1),
converting energy from sunlight to direct current (DC) electricity. DC electricity can then be
converted to alternating current (AC) electricity using an inverter. PV systems can be connected to
existing electricity networks or batteries so that electricity is available in the absence of sunlight.

Whilst solar PV technologies were first developed in the 1950’s the growth of solar PV as an
electricity source has been constrained by production costs. The cost of components required and
the availability of key resources have led to large upfront costs, thus hindered large scale entry to
energy markets. Consequently, the adoption of solar technologies has historically been limited to
small scale private systems. It is only over the past decade that technological innovations and the
realisation of economies of scale have allowed large scale adoption by energy networks around the
world. The following figure shows how the price of PV cells purchased from silicon cell
manufacturers has changed:

Government subsidies, feed-in-tariffs and other polices have played a crucial role in facilitating
solar PV’s entry to energy markets. The entry of solar PV is however, competing with the entry of a
second solar technology – Solar Thermal.

Concentrated Solar Power/Solar Thermal (CSP) involves the conversion of sunlight energy into
thermal (heat) energy. Lenses and tracking mirrors can focus large areas of sunlight into a small
beam. CSP systems are often used to heat air, water and other fluids (e.g. solar hot water systems).
They can also be used to power refrigeration cycles for cooling purposes and to heat steam to
power electricity-generating turbines. Generally, large scale CSP systems are considered to be more
efficient (’00/’000 megawatts and above) than PV systems. CSP Systems are however, relatively
more expensive to install than equivalently yielding PV systems (Australian Renewable Energy
Agency, 2015). These technologies have a significant advantage in that heat/energy can be stored
more easily than a PV system, thus can supply energy more efficiently through peak and off-peak
usage periods. The three main types of CSP systems are the parabolic trough system, the solar
tower (central receiver plant) and the parabolic dish plant (Boruff, 2010).
The hypothetical solar system identified in Chapter 3’s analysis is that of a PV system, in which
96,780 solar modules are arranged in a fixed array (refer to Appendix 1 for Solar Choice 30MW
solar farm output). It is important to note, however, that a similar yielding CSP system covering
100ha could be used. The use of CSP as an alternative requires further research which is beyond the
scope of this dissertation.
2.3 Solar in the world (scale & scope)
It should be borne in mind that the quality of data coverage from international bodies is variable,
given the small scale of many generation projects and access to reliable energy statistics.
Nonetheless, publications from internationally recognised bodies such as the Renewable Energy
Policy Network (REN) can be used to identify general trends. The 2014 Ren21 Global Status
Report indicates that renewable energy had accounted for around 22.1% of global electricity
production in 2013 and that this share would continue to increase over the coming years (REN21,
2014). Of that 22.1% in 2013 it was estimated that around 16.4% was accounted for by
hydropower, 2.9% wind power, 1.8% bio-power, 0.7% solar PV. The remaining 0.4% was
attributed to geothermal, CSP and ocean power (Figure 3). Whilst renewable power generation
capacity is still exceeded by fossil fuel and nuclear it is important to note that renewable energy
sources are attracting policy and investment support and are the dominant supply source to yearly
growth in global electricity demand – in 2013, 56% of net additions to global power capacity were
made up of renewables (REN21, 2014).
7
Figure 3: Global renewable energy contributions
Source: (REN21, 2014)
Solar technologies contributed to both heat and power energy classes and the report noted that from
2009 to 2013 solar PV experienced the fastest capacity growth rate of all energy technologies
(Figure 4). Over the year of 2013 solar PV accounted for about one-third of renewable energy
capacity added globally.

Figure 4: Growth in solar PV capacity
Source: (REN21, 2014)
Over the past 10 years multiple leading world economies have invested in solar PV as a primary
electricity generation source (Figure 5). Germany now generates the most electricity from solar PV
with 21.2% of the global share of installed PV capacity. China, Japan, Italy and the United States
generate 15.6%, 12.9%, 10.2% and 10.1% respectively (REN21, 2015). Australia’s installed
capacity share is far less at 2.3%, yet this exceeds the installed capacity of economies of similar
size such as Canada which has 0.9% of the world share. The 2015 Ren21 Global Status Report also
notes that as of 2015 over 60% of all current PV capacity has been developed over the past three
years. This illustrates global confidence in solar energy as a long term investment for renewable
energy supply.

This evidence could be used to suggest that the general uptake of small and large-scale solar in
Australia is limited. The following section explains why this is not entirely accurate, given
Australia’s rapid investment into small-scale solar systems at the private household level.
2.4 Solar in Australia (scale & scope)
The Australian continent has the highest solar radiation per square metre in the world, therefore
significant potential to harness solar resources (Geoscience Australia, 2015). The highest
concentrations of solar radiation are in the desert regions in the northwest and centre of the
continent. Australia receives an average of 58 million petajouls (PJ) of solar radiation per year –
approximately 10 000 times more than its total energy consumption. The current reliance on solar
energy sources however, is much less than most other developed nations. In 2014 renewable energy
met 13.47% of Australia’s electricity needs while the global average utilisation of renewables was
greater than 20% (Clean Energy Council, 2014). Figure 6 illustrates the breakdown of this 13.47%
between various renewable sources. Of this portion around 16% is attributable to the variety of
solar energy sources, for which 15.3% is from household and commercial solar systems (Table 1).
Australia’s solar contribution is dominated by this sector as 1.4 million Australian households have
installed solar panels on their roofs since 2001 (Wood, 2015). The Clean Energy Council (CEC)
indicated that household solar outpaced the large-scale sector because consumers sought to reduce
10
soaring electricity costs and awareness about climate change and the benefits of solar energy
improved.

The Australian Climate Council has estimated that solar power generation will continue to grow,
contributing 29% of Australia’s electricity needs by 2050 (Climate Council, 2015). It is likely that
this growth will occur in the large-scale PV space. The Australian Renewable Energy Agency
(ARENA) has indicated that investment into large-scale photovoltaics is one of the Australian
Government’s five priorities for new investment. Moreover, Kane Thornton – Chief Executive of
the CEC, noted that large-scale solar PV generation systems are “at an early stage of development”
11
and that there is “significant potential for growth” (Clean Energy Council, 2014). These views and
the current assessment of large-scale PV’s presence suggest that the development of such projects
in the future is inevitable.
2.5 Relevant government policy
There are a variety of government support programs for renewable and solar energy specifically
designed to: encourage research and development, provide finance for projects, assist renewable
energy uptake and to set long term growth goals. To date the Australian government has developed
policies to price carbon, set renewable energy targets, implement feed-in tariffs and has provided
direct financial support.
Feed-in tariffs are widely used in developed economies for the uptake of renewable technologies,
being particularly useful for the uptake of small-scale rooftop solar PV in Germany and the United
States. The Australian Government has also used such tariffs whereby households and businesses
owning small-scale generation systems have been paid for their generation of renewable electricity,
providing credits for each unit of renewable electricity generated or sold to the grid. Gross feed-in
tariff schemes and net feed-in tariff schemes offer varied prices for credits, both of which have
been employed by Australian governments at a state level. These tariffs have prompted Australian
households to invest in small scale rooftop PV systems, contributing to the large portion of
generation capacity shown in Figure 7. Australians took advantage of these tariffs more rapidly
than expected in the early 2010’s, reducing national demand for electricity. Consequently the
Federal Government has urged State Governments to phase out such tariffs and focus on the
development of large-scale renewable technologies (Renew Economy, 2015). This pressure may
also influence the effectiveness of carbon pricing as renewable energy policy increasingly focuses
on large-scale developments.
Carbon pricing effectively places a social price on the consumption of fossil fuels. This makes
fossil fuels relatively more expensive than renewable alternatives. By doing so the government is
attempting to redirect energy investment away from non-renewable resources to clean energy
alternatives. To do so the production of carbon is taxed, to raise revenue that can be reinjected into
renewable energy support programs. This allows market participants which emit carbon to find
innovative ways to source low-emissions energy (Climate Council, 2015), therefore reducing
overall carbon emissions and prompting businesses to invest in renewable energy. Australia
introduced a carbon price commonly known as the ‘Carbon Tax’ under the Labour Party yet it was
repealed when the government changed in July 2014 (Griffiths, 2014). This made previously taxed
12
carbon-based assets relatively cheaper to consume, reinvigorating Australia’s use of fossil fuels for
electricity generation. This move caused non-renewable alternatives to seem relatively less
expensive. It is only through the revision of the Renewable Energy Target (RET) that these losses
have been recovered.
The objective of the RET is ‘to advance the development and employment of renewable energy
resources over the medium term and to assist in moving Australia to a lower carbon economy’
(BREE, 2014). This Federal Government policy was introduced in 2010 to ensure that at least 20%
of Australia’s electricity is produced from renewable sources by 2020. As a part of this policy
legislation was designed that required the RET to be reviewed every two years. Initially it was
thought that 20% of Australia’s annual electricity demand would equate to around 45,000GWh by
2020, so the 2010 policy targeted this figure. Since 2010 however the availability of increasingly
energy efficient appliances, decline in growth of some energy intensive industries (metals &
mining) and the rapid uptake of rooftop solar PV has reduced the national demand for electricity.
Consequently the initial RET target was deemed to have overstated the portion of power supply
that should be provided using renewable energy sources. It is for this reason that two-yearly
reviews have led to the downward revision of the RET. As of June 2015 the target has been
reduced to 33,000GWh (Clean Energy Council, 2015). Prior to this decision ongoing uncertainty
surrounding the RET hindered investment into renewable energy. As such the addition of large-
scale projects over the period 2012-2014 was limited. Bloomberg New Energy Finance estimated
that new investment in large-scale projects such as solar farms reduced by 88% over the 15 month
period that the RET was reviewed. As a part of this year’s review policy makers also removed the
previously legislated reviews required for the RET, meaning that the current target will remain
unchanged until 2020. It is only now that the RET has been finalised that investors can confidently
seek renewable energy opportunities in a more bankable, secure environment. For investors looking
to do so it is important to distinguish between the two components of the RET; the Large-scale
Renewable Energy Target (LRET) and the Small-scale Renewable Energy Scheme (SRES).
The Clean Energy Council explains the SRES as a policy which promotes the installation of
eligible small-scale renewable energy systems by providing a financial incentive to do so. It does so
through the creation of small-scale technology certificates which RET liable entities have a legal
obligation to buy and surrender to the Clean Energy Regulator on a quarterly basis.
The LRET similarly creates a financial incentive for the development of renewable energy
generation systems of capacity greater than 100kWh. A market for large-scale generation
certificates has been created for which developers can sell large-scale generation certificates to
RET liable entities. Large-scale developers can, however, sell electricity directly to the grid. The
13
Clean Energy Council estimates that the majority of the additional 6GWh of renewable capacity
required by 2020 will be provided by between 30-50 major large-scale projects. It can be assumed
that these developments will be dominated by the currently cost-competitive renewable sources:
wind and solar. Since June this year three large wind energy projects and two large solar energy
projects have been approved. Relevant projects are listed and further discussed in the latter part of
this chapter.
Direct financial support continues to be provided to renewable energy projects, research and
relevant investments. This support can be provided through competitive government grant
programs, related investments and donations. Examples of industry bodies which provide such
support are The Clean Energy Finance Corporation (CEFC) and the Australian Renewable Energy
Agency (ARENA). ARENA is an industry body which provides financial support for renewable
energy research and development. ARENA intends to run a competitive solar grant program for up
to 200MW of large-scale solar PV. Proposals will be expected to be between 10MW and 50MW
(DC) and have a levelised cost of electricity (LCOE) of $130/MWh or less (Australian Renewable
Energy Agency; ARENA, 2015). The goal of this funding support will be to substantially reduce
the current gap in commercial competitiveness between large-scale solar PV and wind generation.
Similarly to ARENA, the CEFC released a report in September 2015 outlining a competitive grant
program which is aimed at ‘encouraging greater participation in the large-scale solar sector in
Australia’ (Clean Energy Finance Corporation, 2015). This $250 million program is designed to
help solar retailers reduce the cost of solar development and bolster supply chains. In addition to
CEFC and ARENA funding the solar industry continues to benefit from direct investment from
various public and private companies seeking to invest in an alternative energy future.
Interestingly, Fotowatio Renewable Ventures (FVR), owner of the Royalla and Moree Solar Farms
(Table 2, page 19), has recently been purchased by Saudi Arabia-based conglomerate Abdul Latif
Jameel Energy – a natural resources conglomerate. This may be indicative of a turning point for
investment into electricity generation resource asset classes. Nonetheless, private sector investment
will continue to encourage government policy makers to develop appropriate renewable energy
policies.
These various Government policies will be discussed at an international forum in November 2015
at the Global Climate Summit in Paris. Australian representatives will attend the summit and it is
possible that a strong message will be conveyed for the support of large-scale wind and solar
projects. It is very likely that discussions in this area will find that additional research and
development should be dedicated to these industries.

2.6 Current research & development
Australian researchers regularly contribute to developments in solar PV and CSP technologies. A
variety of research has been recognised internationally for ground-breaking developments over the
past 75 years, dating back to the world’s first solar hot water system which was developed by
Australian scientists in 1941 at the Commonwealth Scientific and Industrial Research Organisation
(CSIRO). Since then Australians have produced highly efficient solar cells, breaking international
records for efficiency. The Australian Photovoltaic Institute (APVI), CSIRO, ARENA, CEC and
leading Australian universities all undertake solar research which continues to provide innovative
and efficient solar technology to the national and international markets. Notably, the University of
New South Wales (UNSW) provides world leading research, having very recent success improving
PV cell efficiency.
Solar cell researchers from the UNSW have set consecutive efficiency records since the early
1980’s and continue to do so. This research continues to be supported by ARENA and the
Australia-US Institute for Advanced Photovoltaics (AUSIAPV). In December 2014 UNSW’s solar
researchers reported the highest ever sunlight conversion efficiency in the world. Using a
commercially available solar cell on the current market the researchers were able to concentrate
sunlight with an optical bandpass filter which captures sunlight that would normally be wasted
(UNSW, 2014). In doing so 40% of the sunlight hitting the cell was converted into electricity, the
highest efficiency ever recorded. The technology was independently tested by the National
Renewable Energy Laboratory (NREL) in the United States and confirmed to be the most efficient
conversion of solar energy in the world (UNSW, 2014). This achievement has far reaching
implications for the current solar industry, since the new technology can be built around existing
solar PV infrastructure. If optical bandpass filters become commercially available to solar
developers the generation capacity for existing solar systems could double or triple in size,
depending on the technology used. This could increase system yields, relatively decrease the LCOE
and reshape Australia’s renewable energy industry. There is significant potential for this
technology to do so, but continued research will be required to determine the most cost-effective
means for integration with existing and future PV systems.
Ongoing solar cell research continues to attract investment in Australia and around the world.
Being the world’s sunniest nation with an international reputation for world leading research, it is
hoped that this investment will continue to improve solar cell efficiency to provide the market with
cheap solar energy alternatives (Flannery, 2013).
15
2.7 Challenges faced
Whilst solar technology is rapidly increasing its capacity, the industry faces a number of challenges
at a global scale. Dr. Faith Birol, chief economist of the International Energy Agency (IEA) named
subsidies for fossil fuels as “public enemy number one to sustainable energy development”.
Subsidies for nuclear power and fossil fuels are estimated to be valued between USD 544 billion
and USD 1.9 trillion, depending on calculation methodology. Financial support for renewable
energy is much lower at around six times less, yet solar PV receives about 73% of this financial
assistance (REN 21, 2013). The IEA suggests that this hurdle will be naturally overcome as the
world economy transitions away from fossil fuels towards renewables, yet it is unlikely that
renewables will become the dominant source of global electricity supply until 2050 (REN21,
2015). Australia subsidises fossil fuels through a variety of Government programs, including diesel
fuel rebates, accelerated depreciation on exploration and accelerated depreciation on mining assets.
As such it is estimated that the Federal Government will spend approximately $13.85 billion in the
next four years on these subsidies (Milne, 2015). These subsidies facilitate the development of
fossil fuel industries and decrease the levellised cost of producing electricity from fossil fuel
resources. Whilst these subsidies remain in place the uptake of renewable alternatives will continue
to be hindered, unless renewables are able to decrease cost efficiencies further. It is for this reason
that the Australian solar industry will continue to be challenged by such subsidies as Dr. Birol
would suggest. Ceteris paribus, solar PV may be able to do so if cost-competitiveness remains
strong at levels shown earlier in Figure 2.
Similar to the challenge posed by subsidies to non-renewable resources, Australia’s solar industry
is directly challenged by the fossil fuels themselves. Australian electricity providers will naturally
seek to produce electricity at the lowest possible cost, thus, use coal and natural gas sources if they
continue to be cheaper. Coal remains Australia’s cheapest electricity generation resource, closely
followed by natural gas. Solar’s competitiveness against these fuels will continue to be dictated by
variations in upfront capital costs, maintenance costs, fuel costs and overall LCOE. The long term
advantage renewables hold over the non-renewables is the knowledge that fossil fuels exist in finite
supply, whilst renewables may be constantly replenished. In mid-2015 the G7 leaders announced
that they had agreed to phase out the use of fossil fuels sometime this century, a milestone which
indicates that the transition away from fossil fuels is gaining certainty.
In addition to competition against fossil fuels, solar energy also competes with other renewable
energy sources. Rather than competing for access to resources, space or specialised skills the
renewable energy generators are competing to provide clean energy at the lowest possible cost. The
International Renewable Energy Agency (IRENA) summarises typical ranges and weighted
16
averages for the total installed costs of utility scale renewable power generation technologies by
region in their Renewable Cost Database (Figure 7).
Figure 7: Comparing renewable generation costs
Source: (IRENA, 2015)
Australia, an OECD nation, exhibits sector competitiveness similar to that shown in the central
panel above. Onshore wind and hydropower systems have previously been the most competitive
generation technologies – explaining why Australia’s renewable energy generation composition is
as shown in Figure 6. Recently though, solar PV has improved cost efficiency. Between 2008 and
2014 the average solar PV LCOE in Australia is estimated to have fallen between 42-64% (IRENA,
2015). In conjunction, IRENA predicts that the industries with the largest remaining cost-reduction
potential are CSP, solar PV and wind. Coupling the realised cost reductions with IRENA’s
predictions it becomes clear that solar PV is in a strong position to challenge the traditional utility
model used in Australia.
Even though this outlook is positive, solar has been challenged by the lack of battery storage
technology and will continue to require improved storage technology to store larger capacities of
electricity. Prior to recent storage developments, solar generation suffered from an inability to meet
peak power demand periods throughout the day. Over the last three years though, battery storage
capabilities have improved markedly. Tesla’s introduction of the Powerwall – a wall mounted
17
battery system which can be integrated with a household’s existing solar PV system and
corresponding gigafactory to produce them is among the most significant developments (TESLA,
2015). In today’s marketplace a variety of battery applications are available to consumers willing to
pay for the technology. Utility scale aggregations of such technology are also available for large-
scale solar systems. This has alleviated the peak-demand supply issue, yet poses the possibility of
homeowners reducing their reliance on the grid. Energy independence would decrease national
demand for grid-based electricity further and challenge the industry to reconsider the future of grid-
supply sources, such as large-scale solar PV. If batteries could be cheaply purchased and integrated
with existing systems the global utility based generation model would become redundant.
Bloomberg Business released a report in June 2015 commenting on this challenge, finding that it is
unlikely that solar energy battery storage will become cheap enough for households to adopt
(Bloomberg Business, 2015). Nonetheless the existing utility model will continue to be exposed to
the risk of redundancy if batteries can be produced with greater cost-efficiency.
The suggestion that large-scale solar is directly challenged by the risk of grid independence implies
that consumers would be willing to invest in small-scale PV systems to take advantage of battery
technology. This implication is exposed to the risk of solar losing social acceptability as a
generation source. A 2015 ARENA/Ipsos study identified solar energy as having a social licence to
operate, particularly more so than wind energy (ARENA/Ipsos, 2015). The study found that solar is
currently seen as a socially acceptable technology in terms of: reliability and efficiency, visual
appearance, environmental impacts, economics and employment and health impacts. 78% of
participants indicated that they are in favour of large-scale solar, whilst 87% indicated that they are
in favour of rooftop PV (ARENA/Ipsos, 2015). Evidently solar PV is not immediately challenged
by levels of social acceptance. Nonetheless, materials used for solar cells may prove to have long
term externalities which have not yet been realised. The future social acceptance of solar could vary
but the current attitudes toward large and small-scale PV suggest that this risk is unlikely.
A challenge particularly relevant to large-scale PV is the knowledge gap between current and
required skilled human capital for development. A 2012 project scope report produced for AGL’s
Energy Solar Project (Nyngan and Broken Hill Solar Plants) identified some current and possible
future challenges for large-scale projects. Firstly, the skills for construction and specialised
engineering design necessary for the development of large-scale solar projects are somewhat
limited in Australia. In 2014 the Clean Energy Council and Australian Bureau of Statistics
estimated that only 543 people worked in the large scale solar industry (Clean Energy Council,
2014). In conjunction, the scope for specialised skills required for the delivery of grid connection
assets (substations and transmission lines) may be too large for a single contractor (AGL, 2014).
18
The market for large scale solar projects may need to mature before the types of contractors that
can offer the entire scope of specialised skills develop. AGL indicated that it would be
advantageous for future projects to use a single engineering, procurement and construction (EPC)
contractor to deliver all the work. However, it should be acknowledged that this challenge should
be considered alongside the demand for specialised skills and costs.
Assuming that these challenges are overcome the development of solar farms will still be limited to
the selection of an appropriate location. This limitation poses a significant challenge to the
development of solar farms. When selecting a suitable location the solar developer must consider
the relevant criteria to be met for the chosen project size. Firstly, proximity to existing transmission
lines and substations should be considered – and the power capacity of the project should be
matched with the transmission capacity of nearby electricity networks. Access to a substation
directly reduces the developer’s expense of building a substation for the purpose of the project.
Similarly, close proximity to a substation keeps expenditure on transmission lines (overhead power
lines or otherwise) to a minimum. It is for this reason that the solar farms listed in Table 2 (page
19) have been constructed in close proximity to transmission networks and existing substations.
Using known transmission infrastructure locations as a guide, a developer can then identify areas of
land large enough for the relevant size of solar farm. The developer needs to consider climatic
conditions for sunlight hours and irradiance (for generation yield) and topographic traits of possible
locations. Land should be relatively flat, cleared, have a northern aspect, not overlap restricted
zoning areas, have minimal risk of bushfire or flooding and have an appropriate soil structure. Once
a suitable location is determined the solar developer must identify the current land use of the area
so that the opportunity cost of constructing a solar farm can be considered. A developer should also
consider the intrinsic value of the land for a variety of existing or possible land uses, with the
attendant public interest attached to this.
An aggregation of these limiting variables shows that it is difficult to identify suitable locations for
large-scale solar systems, particularly as system sizes increase. To solve this problem solar
developers have sought to integrate, co-locate and substitute land areas with landholders situated in
suitable locations with large enough areas of land to facilitate large-scale solar PV – Australia’s
primary producers.
2.8 Assessment of large-scale solar in Australian Agriculture
The increased scale of a solar farm and its location in a high intensity sunlight area improves both
the yield of energy output and overall energy production. Even though Australia receives more
19
sunlight per square metre than any other country in the world, the utilisation of this resource at a
large scale is significantly underdeveloped. The CEC estimated that existing projects contributed to
0.4% of total energy generated in Australia in 2014. This portion is primarily contributed by the
operational (commissioned) solar systems shown in Table 2.

¹Not an exhaustive list of Australia’s large-scale PV systems. This table summarises the five largest operational plants (commissioned) as well as seven large projects which are being developed - identified by the Clean Energy Council ²Land use identified in corresponding environmental impact statements †Land use for projects smaller than 10MW varies significantly
The land area required for the solar farms listed in this table varies for the specific types of
technology used in the system. This depends on the type of technology available and the climatic
conditions for the specific location. In order to determine which technology should be used for a
specific location and the amount of land required developers can conduct private research or invest
in solar consulting/brokering services. Solar Choice is a Sydney based solar broker which provides
such services, and has provided relevant information for the purpose of this analysis; typically,
20
either horizontal single access trackers or fixed PV panels will be used. Horizontal single access
trackers require approximately 3 hectares of land area per megawatt of capacity, whilst fixed panels
require 2-3 hectares for the same capacity system. Land area is also required for the relevant
transmission infrastructure to connect to the nearest electricity network. This means that in total
approximately 100 hectares of land is required for each 30MW of capacity (Gemmell, 2015).
Considering the aforementioned criteria the number of possible locations for a solar farm quickly
diminishes. There are many large transmission nodes in Australia’s urban centres yet multiple
blocks of land would need to be aggregated to obtain the appropriate scale of land required for a
project. Furthermore the opportunity cost of using land in these areas for private and public
developments can be significantly higher than areas of land in regional areas (Solar Choice, 2015).
Regionally located marginal land which is only suitable for agricultural enterprises that does not
have a foreseeable opportunity cost for alternative land uses (such as mining) is therefore the most
suitable. Intuitively it would be thought that land of the lowest productive quality located in the
desert regions of Australia where sunlight intensity is highest is where these criteria would be best
met. The issue however is proximity to existing transmission networks and substations of large
enough capacity to supply enough electricity to the grid. Generation capacities need to be matched
with load capacities for existing infrastructure, meaning that large-scale applications are limited to
certain locations. Similarly the capital cost of installing transmission lines to connect a project to
the grid is approximately $1M/km (Gemmell, 2015). Proximity to a substation of a suitable
capacity is evidently very important to the capital requirements of a project.
An assessment of the chosen locations for some of Australia’s largest operational and planned solar
farms is conducted to identify which types of land have previously been identified as being suitable
for large-scale PV developments. From Table 2 it can be seen that solar farms have been
constructed on a variety of different land areas around Australia, used for cattle and sheep grazing,
dryland and irrigated cropping, and native bushland. In most cases land has previously been used
for grazing purposes to some degree (or still is). Environmental impact statements made publically
available provide this information, yet do not specify the types of grazing or cropping enterprises
used. Further research and consultation with previous and existing landowners could be used to
gather this information. Regardless, it is important to note that cattle grazing enterprises are
commonly situated in areas suitable for solar farms. There are many reasons why this is the case.
As was previously mentioned, solar farms require large areas of land – approximately 100 ha per
30MW of capacity for a PV system. Similarly, close proximity to a transmission line or substation
minimises expenses required to connect to the grid. Climatic conditions have to be suitable,
particularly those for solar irradiation and sunlight hours. Land should be relatively flat or have a
21
slightly northern aspect and be free from restricted zoning areas. The areas of land which suit these
initial criteria best are in central and western New South Wales, and eastern South Australia
(Figures 9 and 10). Figure 8 shows that livestock grazing and dryland agriculture are the primary
land uses for these areas. Dryland agriculture, however, often utilises highly fertile soil types for
various cropping enterprises. It may be found that this land is well suited to such enterprises and
that the opportunity cost of substituting cropping area for solar farming is too high. In conjunction,
fertile black soils present within dryland agriculture zones are unsuitable for large-scale solar
systems. These soil structures can be highly porous and subject to textual variation which inhibits
the soils ability to provide firm support for a solar array. Dryland agriculture zones are therefore
less suitable than grazing land, yet they may still be used if specific conditions are met.
Additionally, a location’s suitability will also be influenced by the risks associated with floods,
fires, dust and pollution. These risks can be assessed on a case-by-case basis and are important
considerations for the longevity of a solar farm.

2.9 Cattle grazing & solar farms
Around the world, solar farms are increasingly being developed on land that supports other grazing
enterprises. The technology offers opportunities for a variety of multipurpose and mixed land uses.
Co-location applications for solar PV have been studied and applied in the United States, co-
production of meat and solar energy has been trialled in Japan, German developers have invested
heavily in solar lease agreements and in India solar PV has been considered for deployment above
canals to reduce evaporation rates and supply grazing enterprises with irrigation for pasture
improvement (Ferroukhi, 2015). The practicality of applying these models to a grazing system
varies. An assessment of the possible interactions between solar farming and grazing is used to
suggest how Australian cattle graziers can integrate existing enterprises with solar farming. Whilst
assessing options for co-location and solar leasing it should be borne in mind that a solar developer
can choose to purchase land directly, negating the need for this analysis. Similarly, a landowner
may choose to develop a solar farm independently from existing enterprises. This analysis is useful
for developers and landowners who seek to avoid large upfront capital expenses for land and
infrastructure, to instead suggest alternate financing options.
Research related to the co-location of large-scale solar systems with grazing enterprises in Australia
is somewhat limited. It is probable that relevant research will be undertaken as Australia’s uptake
of large-scale PV grows. To gain an understanding of co-location opportunities it is therefore useful
to consider research conducted in parts of the world where the uptake of large-scale PV is greater.
A study prepared by Macknick (2014) for the United States National Renewable Energy
Laboratory (NREL) provides a useful summary of integration opportunities. It was found that solar
infrastructure could be strategically placed above a vegetation area so that average vegetation
yields were not substantially affected. Benefits for doing so were not quantified. Rather, qualitative
observations of existing solar farms were used to indicate opportunities. The implications of the
study’s findings for grazing enterprises are significant, particularly for small-animals such as sheep,
goats and free-range poultry. Table 3 summarises the three varied co-location opportunities
identified by this study.
24

Incorporation of elevated solar infrastructure was found to have been used in two main ways as
shown above, where energy centric systems focus on solar energy yields per hectare and vegetation
centric systems focus on grazing yield. It was noted that these models could potentially be used to
provide diversified revenue from small-animal grazing enterprises where high vegetation yield was
not a limiting factor (marginal land). Opportunities for large animal grazing were not identified, yet
it was noted that additional expenditure for rigid solar support structures may be required for larger
animals (Macknick, 2014). This alludes to the problem facing integration with cattle grazing.
The European Bureau of Resource Economics (BRE) indicates that cattle are considered unsuitable
for co-location since they have the weight and strength to dislodge standard mounting systems
(Scurlock, 2014). Cattle cannot graze beneath panels fixed relatively low to the ground and pose
the risk of damaging infrastructure in close proximity. This challenge can be overcome by using
higher, more rigid support structures if consequent problems are resolved. Additional expenditure
may be required for robust panel support structures elevated well above the ground. A solar
developer would be required to identify an affordable type of infrastructure present in the
marketplace in appropriate quantities. Similarly, additional expenditure would be required for the
drilling and installation of such infrastructure. The soil type and presence of bedrock at a chosen
location for a cattle-integrated solar farm would therefore need to be able to support more weight
and facilitate deeper drilling. Higher panels may also require additional electrical wiring for
generated power, a cost which could compound quickly for a large scale project. Finally, general
maintenance practices would need to adapt to taller solar infrastructure. Considering these
limitations it can be said that co-location of a solar farm with a cattle grazing enterprise using
25
current PV technology is infeasible. A solar developer that cannot afford to purchase the required
land for a solar farm should therefore consider an alternate financing strategy – solar leasing.
Solar leasing is a highly prevalent financing method available to solar developers and landowners
around the world, most commonly used in countries where multiple large-scale PV systems exist.
In Germany, for example, 11% of renewable energy capacity is effectively owned by farmers,
where land is leased to solar developers (Ferroukhi, 2015). Solar leases have been used to enhance
the value of marginal land, generate clean energy and to ensure that existing landowners retain
ownership. The advantages and disadvantages for doing so will be discussed later. First, it is
important to understand why a solar lease may be suitable for an existing landowner seeking to
develop a solar farm.
The initial capital requirements for a large scale solar project can be substantial as the resources
required can be costly – particularly those of skilled labour and materials. These resources may not
be readily available to a landowner, meaning that investment in a large scale project may not seem
feasible. For the landowner to invest in large-scale solar as an income source financial assistance
may be required. Finance provided by an investor or a commercial bank could be used to fund a
project, however, individual landowners may find it difficult to gain support from a commercial
bank which lacks experience dealing with these types of projects. Australian solar industry leaders
predict that Australian banks will eventually be comfortable with the process, yet feel that they
have “another one or two year learning curve” before they get to that point (Gifford, 2015).
Investors can therefore be used as a source of funds, an option which may not be readily available
to small private landowners. This issue gives rise to the need for an alternative financing method.
Current alternatives available to Australian landowners include national, state and local government
assistance, private grants and solar leasing programs.
A solar lease agreement is a structured finance agreement held between two or more parties which
enable landholders to install large-scale PV projects without financing the development,
construction or maintenance of the project (Clean Energy Council, 2014). A lease can be facilitated
by solar manufacturers, installers or brokers and can involve partnership with a third party that
provides credible finance. Relevant due diligence can be conducted by the facilitator of the lease to
ensure the bankability of the large-scale project and to identify the most appropriate solar
technology, project size and relevant time frames to be used. The specific terms of a lease are
tailored to individual projects on a case by case basis. Typically the relevant solar supplier is
responsible for the monitoring and maintenance of the system until the lease expires, at which point
the ownership of the project may transfer to the landholder or the supplier.
26
Solar leases of 20-25 years are suitable to landholders who do not wish to sell their land whilst the
project is underway. The lease provides passive income for decades and secures income for
families. However, even if land is to change hands the new landholder can take advantage of the
solar lease, so long as they agree to all the relevant terms and conditions. Building on this, it can be
said that those landholders who are more willing to invest in a passive income source are those
which currently lack one. Businesses may lack passive income for a number of reasons, yet in the
case of cattle graziers it is likely that drought affected or otherwise unproductive enterprises suffer
from unstable cash flow. Intuitively this means that these landowners may be more likely to
consider a solar lease for a large-scale project. It should also be noted that landowners suffering
from poor climatic conditions are more likely to be located further west of the Great Dividing
Range where rainfall is less frequent and sunlight intensity is higher (Figure 10). Higher sunlight
intensity translates to higher solar power output yield, making the investment more attractive to
third parties and the lease more attractive to landowners.
In summary it should be acknowledged that large-scale solar projects do present opportunities for
integration with small animal enterprises as described by Macknick (2014). Even so, in the
Australian context it is likely that solar farm opportunities will need to be identified for areas that
do not use these enterprises. This chapter indicates that cattle grazing land is commonly situated in
suitable areas for solar farms, so for the purpose of this study the relationship between cattle
grazing and large-scale solar will be considered.
2.10 Concluding comments
This chapter’s critical assessment of global and national trends in the solar PV industry finds that of
the two main solar technologies, solar PV has the most potential for large-scale adoption in
Australia. Current trends in the global solar PV industry illustrate that solar PV can be used as a
major source of electricity in a developed country and it is likely that utility generation models of
the future will include more solar PV. It is established that solar leasing can facilitate this change.
In order to evaluate the suitability of a solar lease for a landowner, an analysis of hypothetical and
existing scenarios can be used. It is difficult to describe a typical solar farm, given the variations in
technology used, sunlight intensities in different locations and overall scale of a project. Thus, a
case study of a possible solar farm can be matched to the analysis of cattle grazing enterprises for
the purpose of comparison and evaluation of benefits and costs. This ex ante analysis is used to
provide land holders with economic reasoning to help determine whether a solar farm could be
used as a source of income.
27
Chapter 3: Data Construction for Case Study
3.1 Introduction
The purpose of this chapter is to build a framework required for the ex ante analysis. A
hypothetical solar farm is described in terms of capacity, location, system selection and
corresponding minimum lease price. Typical and representative grazing enterprises for the chosen
location are also described. Finally, the chapter makes relevant assumptions necessary for the
construction of data to be used for analysis in Chapter 4.
3.2 Case study – Armidale 30MW project
For the purpose of this analysis a hypothetical solar farm is described, using data generated by
Solar Choice for the chosen solar PV system size and location (Appendix 1). System yields for this
project and associated data are used to identify a minimum lease price. In doing so, relevant
assumptions are made so that revenue streams from a 20 year solar lease may be evaluated against
revenue streams from representative and typical grazing systems for the chosen location.
A solar lease substitutes grazing activities with solar infrastructure directly, so it is important that a
large enough area of land is used to capture accurate financial performance data for varied grazing
activities and a solar system. Given that a large-scale system is described as having a capacity equal
to or greater than 1MW by the CEC, this size can be used as a minimum requirement. The land area
required to support 1MW of capacity is dependent upon the type of technology used. Solar Choice
identified polycrystalline silicon cells manufactured by Trina Solar to be readily available in the
current market and suitable for this analysis. These cells can be arranged in a fixed array and
generally require 2-3ha/MW (Gemmell, 2015). This area of grazing land is not, however, a large
enough area of land for comparison with cattle grazing systems which generally use much larger
areas of land. It is for this reason that an area of 100ha was chosen. An area this size would
facilitate a much larger 30MW project and provide relevant landholders with a more accurate
indication of potential revenue streams. Thus, using a 30MW capacity solar farm which generates
electricity for a 20 year period, a framework for analysis can be developed. Average costs and
benefits for the described grazing systems are provided by the NSW Department of Primary
Industries (DPI) on a per hectare basis, so financial data for a 100ha case study is easily calculated.
In order to obtain expected generation yields and estimate the value of this 30MW project a suitable
site is identified. As mentioned earlier, a site should be nearby transmission lines or a substation,
28
receive adequate solar irradiance and sunlight hours, present suitable soil types to support
infrastructure and be mostly cleared. A site should also be free from shading and zoning restrictions
and have sufficient protection from flooding and fires. It is also important to consider the
opportunity cost of using land for alternative purposes. Similarly, the social importance of
preserving wildlife systems, maintaining biodiversity and reducing other negative externalities
should be considered. A suitable site which meets these criteria is identified below in Figure 11,
near Armidale, NSW.
Figure 11: Site location
Source: (ARENA, 2015)
The blue shaded area above represents approximately 250ha of land which could be suitable for a
30MW project. Given that climatic data, proximity to the 330kV substation and the topography of
land in this area is similar, the specific 100ha to be used for the solar farm will not need to be
identified. Instead, data can be simulated to estimate output yield and subsequently determine an
appropriate lease price.
29
3.3 Grazing enterprises
When identifying suitable cattle grazing enterprises for the purpose of analysis it is useful to
consider those which are currently used and those which have previously been used for the chosen
location. Beyond this it is important to identify an enterprise which is likely to yield the greatest
returns for existing landowners, irrespective of their current enterprise choices.
Consultation with existing landowners for the selected site in Figure 11 identified multiple current
and previous enterprises. Between landholders a mixture of steer backgrounding, cow-calf
breeding, fat lamb production and small mixed grazing enterprises which rely on off-farm income
are currently used. Steer backgrounding and cow-calf breeding were identified to be the dominant
two enterprises (Foley, pers. comm, 2015). Previous landowners exhibited a similar mix of
enterprises. The major landholder for this location utilises steer backgrounding, as do a number of
neighbouring landowners. This enterprise will therefore be used to describe a typical cattle grazing
enterprise for the greater area.
Steer backgrounding refers to the grouping and acclimatisation of livestock prior to entering a
feedlot or intensive finishing system (MLA, 2015). Typically, livestock are purchased at a young
age, held for a specified period of time and then sold directly to a feedlot. In this instance steers are
purchased at 9 months of age at an average of 240kg liveweight, held for 12 months and sold
directly to a feedlot at a targeted 420kg liveweight. Expected variable costs and income for this
system are estimated using partial income statements provided by the NSW DPI. These summaries
indicate average prices and quantities relevant to inputs and outputs for the enterprise. A complete
summary of assumptions for this data is shown in Appendix 2.
In addition to the typical enterprise for the case study location an optimal enterprise is identified.
From Appendix 4 it can be seen that a similar steer backgrounding enterprise will yield the greatest
revenue for a landowner. Since it has already been established that the case study location can
support a 240-420kg steer backgrounding enterprise it can be implied that a higher profit yielding
240-460kg steer backgrounding enterprise can also be used for the subject land area. The key
differences being expenditure on pasture improvement (Appendix 2 and 3) and income from sales.
As shown by Appendix 3 the assumptions relevant to the provided partial income statement are
very similar to those used for the typical grazing enterprise. Using this information data can now be
constructed for analysis.
30
3.4 Data construction
Before conducting an ex ante analysis consideration for the construction of data is provided. This
includes justification for the use of relevant assumptions. After vindicating the construction of data,
economic analysis is conducted.
In order to evaluate the potential financial implications of solar leasing for existing landholders a
suitable lease price for the solar farm is determined. As per traditional leasing methodology a
suitable lease price could be reached by estimating a portion of the value of land. For grazing land
in NSW the DPI recommends that a lease price of between 5-9% of the value of the land should be
used (DPI, 2007). This methodology could be used to compare the value of a solar lease to
alternative leases yet it will not be included in this analysis. Rather, consultation with Solar Choice
was used to determine an appropriate lease price so that the industry expertise and experience of
staff could be utilised. Using the data simulation shown in Appendix 1 consultation with Solar
Choice concluded that a minimum lease price of $200/ha could be used (Gemmell, 2015).
Managing Director, Angus Gemmell, suggested that a solar developer could engage with a higher
lease price, yet this would place greater pressure on profit margins. Considering the developer’s
need to negotiate a competitive Power Purchase Agreement (PPA) with a power purchaser (in this
case TransGrid) lower lease prices enable the developer to offer a lower PPA price. A lower PPA
price increases the likelihood of the power purchaser being willing to purchase electricity generated
from the solar farm (Solar Choice, 2015). Therefore in the following analysis the minimum solar
lease price of $200/ha is used.
In order to estimate the economic value of a solar farm to an existing landholder using this solar
lease a calculation of the net present value of future benefits/costs is conducted. Over the expected
20 year life span of the case study solar farm income flow is projected into the future. In doing so it
is important to indicate the real value of incomes by holding the purchasing power of money
constant relative to a specific point in time (2015). This excludes the distortionary effects of
inflation. As such, comparisons between values will be meaningful since a dollar at any given point
in time has the same purchasing power (Sinden & Thampapillai, 1995). Real values are also easier
to understand from a landowner’s perspective and are more relevant to current decisions. Using
2015 as a base time period immediate income can then be observed. For the aforementioned solar
farm $200/ha rent would be received by a landowner in the base year. Since the real value of
income is considered over the entire 20 year period the landowner will receive $200/ha for every
subsequent year. For the grazing enterprises however, the expected income to be received in 2015
is calculated. Partial income statements were provided by the DPI in 2012, so the 2012 values are
treated for three years of inflation first. This is achieved by multiplying 2012 values by Australia’s
31
long term average rate of Consumer Price Inflation (CPI). The Reserve Bank of Australia (RBA)
indicates that since inflation targeting began in 1994 for a 2-3% range the economy’s average rate
of inflation has been 2.7% (RBA, 2015). In Appendix 6 this rate is applied to determine base year
values. Base year values are used as current real values and projected 20 years into the future just
as rent from the solar lease is.
The treatment of costs differs slightly. As per the DPI’s partial income summaries (Appendices 2
and 3) the exclusion of all fixed costs and some variable costs is useful for the purpose of analysis
to compare enterprise specific revenue streams. For grazing enterprise variable costs an average
annual rate of inflation of 2.7% is similarly used to calculate base values for 2015. This analysis
offers landholders with a reliable indication of how productive the factors of production which are
directly related to an enterprise are. This is useful because it can signal immediate changes
landowners should make to maximise profit. However, this treatment fails to consider the
additional benefit a landowner receives from a solar lease because that 100ha does not require costs
such as labour, repairs & maintenance, fuels, contracts and administration. That is to say, that it
does not indicate overall changes in net income. The relative expense required for these items can
vary. It is difficult to estimate fixed costs for an average enterprise due to variations in total land
area, levels of debt, machinery schedules, and labour used. As a consequence these costs are not
included in the initial calculation of net present values. Rather, by considering a basket of these
expenditure items as an additional benefit (income stream) for a solar lease their influence on net
present values can be accounted for. Sensitivity analysis is used to create possible scenarios where
fixed costs increase typical steer enterprise total expenditure by 10, 20 and 30%. 30% is selected as
the maximum sensitivity because an increase in costs beyond this point would see the typical
enterprise reach a breakeven point. Incremental rates of 20% and 10% are used to estimate relative
changes in net present values.
Incomes and expenses are expressed per 100ha for the purpose of this analysis, as 100ha is required
for the 30MW solar farm. Values for the DPI’s specified 240-420kg and 240-460kg steer
backgrounding enterprises are based on land areas of 97ha and 108ha respectively. In order to
ensure that exactly the same land area is used between all enterprises income and expenditure items
are adjusted proportionally to suit 100ha. It is for this reason that all values for the typical
enterprise (240-420kg steer backgrounding) are increased by 3.09% and for the optimal enterprise
(240-460kg steer backgrounding) are decreased by 7.41%. This ensures greater accuracy for results
by providing a more realistic indication of income flows for 100ha of each enterprise. Data is
standardised over the same area of land and shown in real values for the base year – 2015. Future
income and expenditure is projected 20 years into the future as shown in appendices 5, 6 and 7.
32
Future outcomes are converted to equivalent present values using an appropriate discount rate. This
is the percentage rate of compound interest for which future benefits and costs can be adjusted to
equivalent present-day values. However, it is difficult to determine which rate should be used
because the value of future outcomes may vary between individuals. Moreover, the flow of future
outcomes for different alternatives can be exposed to varied levels of risk. It is for this reason that
three different discount rates are used to estimate the value of future outcomes. The New South
Wales Treasury recommends a central real rate of 7% should be used, including sensitivity analysis
for rates of 4% and 10% (New South Wales Treasury, 2007). These rates represent the real rate at
which future outcomes are valued which is consistent with the real values used for projections of
future income and expenditure. Net present values of future outcomes are calculated on a yearly
basis. The addition of net present values indicates the estimated value of the project to the
landowner for the 20 year period.
The net present value of an outcome at any year in the future is calculated as;
NPV = !!
(!!!)!
where ′𝐵!′ is benefit in time period ′𝑡′ and ′𝑖′ is the discount rate
Similarly, the sum of net present values can be calculated;
NPVSUM = !!!!! !
!
!!!
For gross margin analysis, values can be compared on a per hectare basis. In an agricultural context
a gross margin may be defined as the gross income from an enterprise minus the variable costs
incurred in achieving it. A gross margin is a useful indicator for landholders because it shows how
much revenue a business can generate from an enterprise minus the variable costs incurred in doing
so. In the context of cattle grazing enterprises this can be represented as a dollar value per hectare,
rather than as a percentage of overall revenue (as accounting generally would express a gross
margin). This is useful for the selection of the most profitable enterprise for a farm business and
can be used to determine the minimum price point to be used for the price of a solar lease. In
December 2012 the NSW DPI provided budgets for varied livestock enterprises, including cattle
enterprises shown in Appendix 2. This data is based on a 100 cow herd with a weaning rate of 86%
(NSW Department of Primary Industries, 2015). Using the Australian Bureau of Statistic’s CPI
calculator tool these values are altered to reach more accurate 2015 values (Australian Bureau of
Statistics, 2015).
33
3.5 Concluding comments
From Chapter 3’s data construction the main parameters to be used for the following case study
analysis are: 100ha grazing land, fixed solar lease price of $200/ha for a 30MW system, 20 year
time frame, typical enterprise of steer backgrounding for 240-420kg and optimal enterprise of steer
backgrounding for 240-460kg. 2012 DPI partial income summary values are adjusted for 100ha and
inflation to reach 2015 base year values. It is assumed that this adjustment provides an accurate
reflection of 2015 cattle prices. It is also assumed that these may be treated as real values, so real
discount rates of 4, 7 and 10% are applied for consistency. Using this information analysis is
undertaken to provide results shown in Chapter 4.

Chapter 4: Ex ante Analysis
4.1 Introduction
This chapter provides a summary of results for the three different scenarios. A central
discount rate of 7% estimates the net present value of each alternative and appropriate sensitivity
analysis indicates the relative influence of varied discount rates. Gross margin analysis is also used
to compare alternatives with appropriate sensitivity analysis. Both of these pieces of analysis are
used to estimate breakeven points between alternatives.
4.2 Net present values
The calculated net present value sums are summarised and presented in Table 4. Models used to
calculate these values are shown in appendices 5, 6 and 7. The choice of each discount rate can be
seen to have a significant influence on results. Each value shown in Table 4 indicates the value of
an alternative over 20 years in real dollar terms for a corresponding discount rate. The alternative
yielding the highest net present value is shown to be $362,315.66 for ‘Steers 240-260kg’ with a 4%
discount rate. Conversely, the lowest net present value is $190,271.27 for the solar lease when a
discount rate of 10% is used. An interpretation of these results and corresponding analysis is
provided in Chapter 5.

*100ha case study
To account for the influence of fixed costs which are not measured in Table 4’s results, further
sensitivity analysis is used to price the additional expenditure items in baskets of 10, 20 and 30%
increments as additional revenue streams for the solar lease. Using the $200 lease price as a base
the additional grazing expenditure can be seen as an addition to rent revenue. Respective additions
are shown in Table 5 below. These additions are included in the model shown in Appendix 9.

In Table 5 base values represent total expenditure for each enterprise as estimated for 2015.
Additional expenditure baskets are calculated as proportional increases in base values. Under each
value an indication of the net effect on total expenditure is illustrated on a per hectare basis. These
per hectare additions are directly added to the $200 lease price to yield new net present values
shown in Table 6. With the central real discount rate of 7% the new rent revenues are entered into
the discounting model (Appendix 9). In effect, the new values illustrate the addition of original
solar lease net present values and the benefits of saving expenditure on fixed costs. Table 6
summarises these results:
Table 6: Net present value sums, including fixed cost savings

Alterations to the solar lease price are also used to determine the point at which rent revenue from
the lease would breakeven with each enterprise. By identifying the net present values for each steer
backgrounding enterprise at a certain point in time then solving for benefit in the corresponding
time period, this can be achieved. Calculation provided the following breakeven points:
Table 7: Breakeven lease prices
Enterprise Solar lease breakeven price ($/ha) Steers 240-420kg 213.11 Steers 240-460kg 248.33
Since real values are used for the projection of future outcomes and the same three discount rates
are applied these lease prices yield the same net present values as each corresponding enterprise for
each discount rate. Evidently, this means that the breakeven solar lease prices are equal to the 2015
gross margin per hectare rates for each grazing enterprise.
36
4.3 Gross margin analysis
In order to compare gross margins for each cattle enterprise and the solar lease in 2015, the
provided DPI partial income statements are altered. Appendices 10 and 11 show how 2012 values
for each enterprise are first adjusted to suit an area of 100ha and then treated for average annual
inflation of 2.7% for three years. In each it can be seen that gross margins proportionally increase
over the time period. A simplified summary of each alternative’s gross margin is presented in Table
8, showing that in both cases a solar lease’s gross margin is not as competitive.
Table 8: Gross margin results

*Gross margins quoted include pasture improvement costs
Gross margin analysis is also used to estimate the influence of a drought year on returns from each
enterprise. For a solar lease the gross margin will not change during a drought year so this value
remains unchanged. For the two steer enterprises however, gross margins can vary significantly. It
is difficult to estimate the average severity, duration and timing of a drought period, so for the
purpose of this analysis the following assumptions are made. It is assumed that drought conditions
begin when 9 month old steers are purchased (the start of the 12 month period) and that the
landholder is aware of this. Instead of spending cash on pasture improvement as shown in the DPI
summaries this cost is transferred to expenditure on hay and grain. There is no net effect on total
expenditure and livestock purchase prices are held constant. It should be noted though that in a
drought, purchase prices may change as the supply of cattle to the market increases. The critical
variable to be changed is ‘liveweight kilograms sold’, since drought conditions stress livestock and
limit weight gain. The influence of a drought is calculated by accounting for decreased liveweight
kilograms sold. Table 9 summarises the influence this has on income, using a 10% decrease in
liveweight from data in appendices 2 and 3. These results illustrate that the described drought
conditions decrease gross margins to $127/ha for the 240-420kg steer enterprise and $165.03/ha for
the 240-460kg steer enterprise. The solar lease, however, remains the same at $200/ha. The key
finding of this result is that regardless of drought conditions a solar lease can generate secure
income. Implications of this finding are discussed in the following chapter.
37
Table 9: Comparing initial liveweight yield to drought year yield
Enterprise Income ($) Gross margin ($/ha) Normal Year Steers, 240-420kg 85,768.77 213.11 Drought Year Steers, 240-420kg 77,191.89 127.16 Normal Year Steers, 240-460kg 83,301.29 248.33 Drought Year Steers, 240-460kg 74,971.16 165.03 Normal Year Solar Lease 20,000 200.00 Drought Year Solar Lease 20,000 200.00
In contrast to drought year gross margins, grazing enterprise yield may vary due to cattle price
changes. Additional gross margin sensitivity analysis is used to account for price variations of
livestock purchased and sold. Average yearly price variations for the typical and optimal grazing
enterprises are not available, so data sets for similar steer enterprises are observed to determine
levels of price volatility. Appendix 12 shows that for a similar steer enterprise, trade steers
weighing 330-400kg, cattle prices varied between 15-20% from the period 2010-2015 (NLRS,
2015). This volatility justifies the use of sensitivity analysis to account for a 20% change in cattle
prices. Appendix 12 shows that a 20% change in prices would cause the typical steer enterprise
gross margin of $21,311.26 to increase to $28,549.66 or decrease to $14,072.89. This means that if
2015 prices are 20% greater than shown appendices 10 and 11, a typical 240-420kg steer
backgrounding enterprise may yield a 34% greater gross margin per hectare, of $285.50. Similarly,
if 2015 prices are 20% lower, the typical enterprise may yield a 51% reduced gross margin of
$140.73/ha. These findings are discussed with reference to the current cattle market in Chapter 5.
4.4 Concluding comments
In summary, the results of this study’s ex ante analysis are able to provide landholders with
economic reasoning to make enterprise decisions. It is apparent that a solar lease generates less
value than steer backgrounding enterprises when future outcomes are discounted at the same rate.
The value of a solar lease relatively increases when consideration is given to the influence fixed
costs may have on grazing enterprises. Gross margin analysis similarly finds that a solar lease
generates more value under certain circumstances – including drought. These findings are
discussed in Chapter 5 to evaluate possible implicaitons for landowners, solar developers and
governments.
38
Chapter 5: General Discussion and Conclusions
5.1 Introduction
The purpose of this chapter is to summarise the key findings of this study and to suggest
some relevant implications for landowners, solar developers and policy makers. It provides a
landholder-centric analysis of two cattle grazing enterprises and a solar lease which determines the
intrinsic value of each alternative to the landholder over a 20 year period. This includes varied
treatments for enterprise costs and simple breakeven analysis. In addition, gross margin analysis is
used to comment on the potential for each alternative to maximise profit. Building from this
analysis consideration is given to situations where enterprise gross margins are substantially
affected. Implications of this analysis are suggested with reference to an assessment of large-scale
solar PV conducted in earlier chapters.
5.2 Overview of the study
The main objective of this case study is to conduct an ex ante analysis of the possible implications
of solar farms for Australian cattle graziers. The main research question is to determine whether it
is beneficial for these landowners to engage with large-scale solar projects using solar lease
agreements. An ex ante evaluation addresses this question using primary and secondary data to
analyse net present values and gross margins. Results from this study are considered with findings
from a literature review and assessment of solar PV in the world, Australia and agriculture through
earlier chapters.
Chapter 2 established that global energy supply will inevitably shift to renewable generation
sources. Solar PV technology was identified as an increasingly cost-competitive source of
renewable energy around the world currently used by multiple large developed economies as a
primary electricity generation source. Australia’s reliance on renewable generation sources,
however, was found to be proportionately less than the global average. In particular, solar PV
accounts for only 2.1% of national demand for electricity. 2.5% of this portion is attributable to
large scale PV. If solar is to provide for 29% of Australia’s annual electricity demands by 2050 as
the Australian Climate Council predicts, substantial changes to the current generation model are
required. An assessment of recent trends in investment, cost efficiency, development and potential
for solar PV finds that Australia’s large-scale PV sector is likely to grow rapidly over the coming
decades. The chapter concludes by identifying how and where this growth can occur – Australian
39
grazing land. Findings from this section are used to support economic analysis in the following
chapters.
Chapter 3 builds on this assessment to construct a case study for analysis. A demonstrative model
for the development of a solar farm is built using representative cattle grazing enterprises and a
solar lease agreement. Relevant assumptions are made to approach the analysis in a landholder-
centric manner. Net present values, gross margins and associated sensitivity analysis are used to
provide economic reasoning that can help cattle graziers identify with the possible benefits of solar
leasing. Chapter 4 provides a summary of the results of this analysis which will be referred to in
this chapter’s discussion. Key findings from this study and possible implications are discussed in
the following section.
5.3 Summary and implications
5.3.1 Summary of results
Chapter 4 provides a summary of results obtained from ex ante analysis. An interpretation of results
is provided in this section so that subsequent implications can be identified. For net present value
calculations future outcomes are projected as real values using real discount rates so it can be said
that these results reflect the value of each alternative in real dollar terms.
Table 4 highlights initial net present value sums before fixed costs are accounted for. The relevant
costs and benefits shown are those which are directly related to the generation of income from each
activity. Each result contains a positive figure, so it can be said that any alternative will provide the
landowner with net gain. The alternative with the highest net present value has the highest net gain,
making it the most desirable. A preliminary interpretation of results can be conducted by observing
net present values at equivalent discount rates. The results illustrate that the optimal 240-460kg
steer backgrounding enterprise yields the greatest value for the landowner at each rate. The greatest
value - $362,315.66 is realised when this enterprise is chosen and a 4% discount rate is applied.
Similarly, at each equivalent discount rate the solar lease is the least valuable, where a discount rate
of 10% yields the lowest net present value of $190,271.27. Using these interpretations a typical
landowner has no incentive to use a solar lease. Instead, the typical landowner should seek to adopt
the heavier steer backgrounding enterprise. However, this interpretation fails to consider which
discount rate is most suitable for each alternative.
When analysing results it is important to understand the influence of each discount rate and the
basis for choosing between them. The low rate, 4%, is based on the concept of individual time
40
preference, whilst the higher rate, 10%, is based on the concept of opportunity cost (Sinden &
Thampapillai, 1995). A higher discount rate places greater emphasis on short term outcomes and
other opportunities, since the value of future benefits decreases relatively faster. Conversely, the
lower rate reflects the value of future outcomes where an individual is indifferent between present
and future values, so should be applied when long term costs/benefits are well known. The
difference between a high rate and a low rate is therefore considered as a risk premium. When risk
is higher, a higher discount rate should be used and vice versa.
For existing landowners the relevant costs are variable and short term in nature. As such a
landowner can use values from these calculations to determine the best way to maximise short term
profit. By projecting the outcomes of a choice 20 years into the future the landowner can gauge the
suitability of a current choice if variable costs are expected to remain the same. This means that if
the landholder is unsure how variable costs will change over the 20 year period a discount rate of
7% or 10% should be observed. On the other hand, if landowners are confident that they can
predict these costs over the next 20 years the lower discount rate of 4% can be used. Even though
the cattle grazing industry is mature and relatively stable, cattle graziers are ‘price takers’ so they
are vulnerable to short-term price volatility. This makes it difficult to estimate variable
costs/benefits. For these reasons the central discount rate of 7% can be used to capture both the
influence of the industry’s stability and susceptibility to price changes. By contrast, a solar lease
agreement is contractually enforceable, meaning that a landowner can almost certainly predict
future income over a long period of time. It is for this reason that a landholder should use the net
present values indicated by a 4% discount rate to estimate the value of the solar lease. Using this
knowledge the results summarised in Table 4 can be reinterpreted.
For the central discount rate of 7% the typical 240-420kg steer enterprise yields a net present value
of $247,083.02. This indicates that the sum of future benefits generated from this enterprise over
the next 20 years is worth $247,083.00 in current dollar terms. For the optimal 240-460kg steer
enterprise the sum of future benefits is worth $287,910.68. Both of these options are worth more
than a solar lease if the 7% discount rate is applied, yielding $231,880.28. However, since returns
from the lease are nearly certain it is more appropriate to value the benefits of the solar lease using
a 4% discount rate. At this rate a 20 year solar lease is worth $291,806.53 in real dollar terms,
making it the most desirable alternative. Under these assumptions a landowner could choose to
enter a solar lease agreement to maximise net benefit. Even though this provides a good indication
of which alternative is the most profitable it does not include the effects of fixed costs. In order to
account for the influence of fixed costs which are not shared (excluded) between each alternative
further analysis is required.
41
In situations where fixed costs increase total expenditure a landholder can consider the savings
from avoiding these costs as being equivalent to additional income received from a solar lease. This
approach is useful for landholders who are currently using one of the described steer enterprises
that are considering a solar lease. For these calculations the central real discount rate of 7% is used
to capture the risk of fixed costs changing in the long term. The real dollar value expressed through
a net present value using this approach therefore reflects the addition of actual benefit and the
implied benefit of cost reduction.
Sensitivity analysis is used to test the influence an accounting for fixed costs will have on net
present value by using increments of 10, 20 and 30% to increase total expenditure. For each test
fixed costs are considered together as a basket of costs, as shown in Table 5. Fixed costs vary for
grazing enterprises, so landholders can use Table 6 to determine which portion of fixed costs best
suits the cost structure for their enterprise. Landholders can then more accurately identify the
possible benefits of a solar lease using this information. As shown by Table 6, a landholder who is
currently using the typical 240-420kg steer backgrounding enterprise may be subject to an increase
in total expenditure by 20% when fixed costs for the 100ha are accounted for. If this is the case the
net present value of a solar lease increases to $381,385.10. This means that by accounting for fixed
costs the solar lease becomes 64.48% more valuable to the landholder. It should be borne in mind
that in reality the solar lease won’t provide additional income. Instead, the grazing enterprise is
relatively less valuable. Other results from hypothetical cost structures have notable results. In
particular, a grazier who is using the 100ha for typical 240-420kg steer backgrounding who
accounts for fixed costs through a 30% increase in total expenditure stands to gain 96.72% more
value over the 20 years using a solar lease. The net present value for a solar lease under these
circumstances is $456,143.30. Other income sources from the same 100ha may distort this
approach by making grazing enterprises relatively more profitable. Consequently this sensitivity
analysis should only be used by landholders whose enterprise suit the benefit-cost structure
described in this model.
Lease prices are also altered to determine the breakeven points between a solar lease and each
enterprise. Table 7 shows that for 240-420kg steers the breakeven price is $213.11/ha and for 240-
460kg steers the breakeven price is $248.33/ha. These values correspond to the breakeven gross
margins for each enterprise on a per hectare basis. Using the same discount rate a grazier would be
indifferent between each alternative. In reality however, the lower 4% discount rate is suited to the
solar lease and the 7% discount rate is suited to each grazing enterprise. At these rates the lease
prices required to see net present values break even with each steer backgrounding enterprise are
calculated by testing the model in Appendix 5 for the corresponding net present values. For 240-
42
420kg steers a lease price of $169.34 would result in a net present value of $247,083.02 for each
choice. Similarly a lease price of $197.33 yields a value of $287,910.68 to breakeven with the 240-
460kg steer enterprise. Logically this implies that if grazing enterprises are discounted at a 7% rate
and the lease at a 4% rate the solar lease will always generate more value than each enterprise. A
landholder could use this information to identify solar leasing as a more valuable alternative.
In addition to discounting future outcomes from each alternative current differences between each
cattle enterprise and a solar lease can be evaluated using gross margin analysis. This analysis is
useful for an evaluation of the influence a drought will have on gross margins. Gross margin data
for 2015 is constructed in appendices 10 and 11, in order to adjust 2012 DPI values for average
annual inflation. Table 8 summarises these changes, showing that in 2015 the typical 240-420kg
steer backgrounding enterprise gross margin is $213.11/ha, the optimal 240-460kg steer
backgrounding enterprise gross margin is $248.33/ha and for the solar lease $200/ha.
Using this information a landholder can see that per hectare the optimal steer enterprise is the most
profitable, followed by the typical enterprise and then the solar lease. As discussed earlier though, a
landowner should also consider the portion of fixed costs per hectare from each grazing enterprise.
Consideration for these costs will make the solar lease seem more profitable on a per hectare basis
(Table 6). Net income per hectare is evidently a more useful measurement for landowners to
consider when evaluating the benefits of solar leasing. Even though gross margin analysis fails to
account for some costs it can be used to estimate the influence a drought and price volatility have
on each alternative.
The timing and duration of a drought and the severity of climatic conditions can vary. For this
reason it is difficult to describe a typical drought, so relevant assumptions are made. Chapter 4
outlines these assumptions, where the critical variable influenced is liveweight kilograms sold. The
DPI’s partial income summaries for each enterprise show how liveweight kilograms sold influence
sale prices, so using this information a decreased sales yield of 10% is used to estimate the
influence a drought has on gross margins per hectare. Table 9 summarises this information. For a
typical 240-420kg steer backgrounding enterprise the described drought causes a reduction in
income from sales to $77,191.89. This reduces the enterprise’s gross margin to $127.16/ha – a
67.59% reduction. For the optimal 240-420kg steer backgrounding enterprise income is reduced to
$74,971.16. The associated gross margin is $165/ha – a 50.48% reduction. For the solar lease the
gross margin of $200/ha will not change during a drought year. As such, it can be said that under
drought conditions a solar lease may generate stable income for a landowner. Moreover, by
accounting for fixed costs or considering situations where liveweight yield decreases further a solar
lease’s income may seem relatively more desirable. This highlights a potential advantage of using a
43
solar lease. A solar lease can provide a low-risk income source to landowners irrespective of
climatic conditions. It is likely that over a 20 year period the existing landowners will experience
multiple droughts so this information is particularly relevant to current enterprise choices.
Conversely to the influence of a drought, Chapter 4’s sensitivity analysis illustrates that cattle price
volatility can significantly increase gross margins. A 20% increase in the price of cattle may lead to
a 34% increase in the typical steer enterprise’s gross margin (Appendix 12). In this situation the
value of a solar lease markedly decreases for the landowner. The 2015 330-400kg steer market
prices illustrate that current market prices are higher than those shown in appendices 10 and 11
(NLRS, 2015). Therefore, it is possible that previous analysis understates actual 2015 cattle prices.
Whilst the current prices may overstate actual values it is useful to consider the influence a 20%
decrease in prices has – which could lead to the typical enterprise gross margin decreasing by 51%.
As such, landowners should undertake enterprise decision making with the most accurate data
available.
The most significant findings of this analysis are that a solar lease can provide a secure income
source for cattle graziers for long periods of time and that in certain situations a solar lease can also
generate more income. Consequently, a low discount rate can be used to estimate the value of
future benefits and landowners can use a solar lease as a low-risk income source to avoid losses
during drought. Additionally, a minimum lease price of $200/ha can generate more value than both
typical and optimal cattle grazing enterprises under certain circumstances.
Under circumstances where fixed costs increase total expenditure by 10% for each enterprise a
$200/ha solar lease presents more value for the 20 year period for equivalent discount rates.
Compounding this information with the knowledge that a lower 4% rate is best suited to a solar
lease it can be said that a solar lease is very likely to generate more value for landowners in the
long term. The implications of these findings are discussed in the following section.
5.3.2 Implications
The implications of these results vary for landowners, solar developers, policymakers and society.
Landowners can use this study to identify whether their location is suitable for a solar farm. If land
is suitable they can evaluate the possible opportunity of engaging with a solar lease agreement on a
per hectare basis. This study describes the typical and optimal enterprises as steer backgrounding
for two different weight classes using information provided by the DPI. As shown in Appendix 4
these two enterprises yield greater gross margins per 100 hectares than most other listed
44
enterprises. Therefore it can be implied that for most other listed enterprises solar leasing can be
used by a landowner to generate relatively more value than what is shown in this study.
Furthermore, enterprises which are not considered in the DPI summary can use this analysis to
evaluate the potential implications of solar leasing by comparing the lease model used in this
analysis to their enterprise benefit/cost structure. Regardless of a landholder’s existing enterprise no
establishment costs are required and the landholder can be relatively certain of future returns once a
lease price is negotiated.
It is difficult to value the social benefits provided by the 30MW solar farm. Even still, a landholder
can view a solar lease as a socially beneficial alternative which reduces carbon emissions and
generates electricity for households that utilises a renewable resource at little or no social or private
cost. The hypothetical 30MW solar farm described in this study is estimated to be able to produce
51,893MWh of electricity annually (Appendix 1). The DPI has advised that 1.37kg of CO2
emissions are produced for every kilowatt hour of electricity, using a 2013 generation model (DPI,
2013). Therefore the described 30MW solar farm could save up to 71,093.41 tonnes of CO2
emissions annually. The 51,893MWh of electricity produced annually should also be able to power
8,160 Australian homes. Evidently, society benefits significantly for every 30MW of solar PV
generation. Solar developers and landowners may consider this information to estimate the
additional social value of developing a solar farm. With reference to the ARENA/Ipsos social
acceptance report, a landowner may also derive benefit from the knowledge that he/she is helping
the community adopt renewable energy. Whilst these benefits are difficult to price they are
important to acknowledge for a landholder considering a solar lease.
A solar developer can use this study to gain a better understanding of the way in which a landholder
will seek to maximise returns from land using a variety of enterprises. This knowledge can be used
when negotiating a solar lease to calculate a fair price which creates value for the landholder and
allows the developer to engage with a competitive PPA. Furthermore, landholders who become
aware of the possible benefits of solar leasing described in this report may identify themselves to
solar developers as having land which could potentially be used for a solar farm. This can reduce
the expense a solar developer incurs in identifying possible locations and could create opportunities
for business growth.
The findings of this paper can also be used to recommend opportunities for governments to assist
with the development of large-scale solar PV. Chapter 2’s assessment of large-scale PV in
Australia can be used to highlight the potential for growth in the sector. It should be noted that
other developed economies have been able to adopt solar PV as a primary energy source and that
Australia will inevitably need to change its energy generation mix. Solar energy is identified as an
45
increasingly cost-competitive source of electricity with significant potential to meet Australia’s
electricity demands. It is also apparent that the development of large scale PV projects will require
large areas of land in suitable locations, establishing the need to research ways such projects can be
integrated or substituted with existing enterprises. It is for these reasons that funding for solar PV
research may be required to identify the most effective ways to integrate or substitute solar farms
with existing enterprises. For this study though, recommendations are made to suggest how policy
makers can assist with the development of solar farms using solar leasing agreements. To be
consistent with earlier analysis, recommendations are made with consideration for the additional
benefits a landholder could derive from government support.
Government support via subsidies or competitive funding programs could be used to encourage
landholders to use their land for solar farming. Solar developers are currently challenged by the
difficulty of selecting a suitable location and negotiating agreements with landholders. Subsidy
support could provide a financial incentive for existing landholders to identify their enterprises as
having potential to utilise solar leasing.
An example of how a subsidy could be used in such a way can be derived from the results shown in
Tables 6 and 7. This piece of analysis accounted for additional expenditure on fixed cost items as
baskets of costs that increased total expenditure by 10, 20 and 30%. Just as analysis considered
these as additional benefits of solar leasing they can also be considered to estimate the value that
could be created by a subsidy. For instance, if a landowner was paid a $64.47/ha subsidy for
undertaking solar leasing the effective rent revenue earned from the lease could be $264.47/ha,
assuming the original $200/ha lease price. If the subsidy was in place for the duration of the lease
and a 100ha project was used, the resulting net present value would be $306,626.89 (Table 7).
Therefore by providing $6,647 annually through a subsidy the solar lease creates 32% more value
for the landowner. This may increase the likelihood of existing landowners approaching solar
developers to consider lease agreements for solar farms. A similar subsidy could be used to provide
solar developers with a financial incentive to develop solar farms. Benefit could be transferred to
the developer by providing $64.47/ha of solar farm installed. This would assist the negotiation of a
fair lease price between each party, where benefit could still be passed on to the landholder through
a higher lease price. This example illustrates that a relatively inexpensive subsidy could be used to
create significantly more value for existing landowners and developers.
A number of other means may be used to provide support for large-scale PV. However, additional
research may be required to evaluate the potential usefulness of varied support programs. For this
study a subsidy is shown to be a simple, cost-effective way to create value for landholders and solar
developers.

5.4 Areas for further analysis
This analysis is structured in a landholder-centric manner so that the potential implications of solar
farms for Australian cattle graziers can be evaluated. An assessment of large-scale solar PV in
Australia reviews existing secondary data and case study analysis provides an evaluation of one
particular opportunity – a solar lease. As such there are a number of opportunities for further
analysis. Before suggesting additional opportunities the limitations of this paper are mentioned. For
the purpose of analysis a number of assumptions had to be made for data construction. Some of
these assumptions present research limitations, which may require additional research to be
undertaken.
A hypothetical solar farm is described using solar PV technology that is currently available in the
marketplace. The capacity of the solar farm is representative of a typical large-scale project and a
possible location is identified. Further study could be used to test the system yields possible for
other large-scale solar technologies such as CSP. Similarly, other locations could be used to test the
value of a solar farm to different grazing enterprises. The $200/ha lease price was provided by
Solar Choice, so additional developers could be approached for alternate pricing information. In
total, additional research could be used to test the potential implications of large-scale solar using a
different technology, location, capacity and pricing model. Similarly, it may be useful to research
the potential for co-locating cattle grazing enterprises with large-scale solar systems.
For the chosen grazing enterprises and associated financial information a number of limitations
exist. Partial income summaries use information from 2012 and fail to account for all costs relevant
to the land area used. Considering current increases in cattle market prices it is very likely that this
study understates the profitability of each grazing enterprise. More recent data that incorporates
current prices and all fixed costs for each enterprise could be used for further analysis to evaluate
the implications of solar leasing for graziers. Further analysis could also be used to test the value of
a solar lease against varied agricultural enterprises such as cropping, sheep and free-range poultry.
Regardless of the topic for future study though, the findings of this paper can be used to show
relative differences in value using a landholder-centric ex ante analysis.
5.5 Concluding comments
This paper builds on existing research to determine current and expected trends for the solar PV
industry. It was found that Australia’s uptake of large-scale solar lags behind the global average
uptake and that it will be necessary for this to change. There is significant growth potential for solar
47
farms in Australia and it is very likely that cattle grazing land can accommodate their development.
Cattle grazing cannot, however, be integrated with large-scale solar under a co-location model
because current solar technology is not suitable for interaction with large animals. Instead, solar
leasing was identified as the most suitable way to develop solar farms on grazing land using current
solar PV technology. It was found that landholders can create value in the short and long term using
solar leasing, in the majority of circumstances. Analysis showed that solar leasing can provide a
secure income source for graziers. This is particularly desirable when the influences of drought
conditions on income are considered. Case study results illustrate that if Australian governments
are to support the growth of large-scale solar PV, inexpensive leasing subsidies can be used to
create significant benefits for landowners and developers. This paper may be used to identify the
potential for private and societal value creation through large-scale solar PV.

Care is needed in purchasing the right type of cattle which are likely to be at the higher value end of the market. This is a specialised operation. Freight costs will vary depending on proximity to major feedlots.
Production Information: Breeds preferred Murray Grey, Angus, Shorthorn or Wagyu/British crosses when available. Liveweight scales on farm are essential. Growing out enterprises can be risky because of the price variation in both purchases and sales. Producers should consult the table on the previous page that shows gross margin changes due to variation in purchase and sale prices. Producers should determine the maximum purchase price they are prepared to pay before the sale. Liveweight and description buying are recommended methods.

Later maturing types prefered for the Japanese feedlot 120-150 day grain fed market. Some could be taken through to the Korean/EU market. Freight costs will vary depending on proximity to major feedlots.
Production Information: An increasingly common option in the Riverina and North West of NSW. There will generally be a need to finish the weaning process of stores after purchase which requires adequate facilities on farm. Growing out enterprises can be risky because of the price variation in both purchases and sales. Producers should consult the table on the previous page that shows gross margin changes due to variation in purchase and sale prices. Producers should determine the maximum purchase price they are prepared to pay before the sale. Liveweight and description buying are recommended methods.
