Southern Africa

• On Site Power in an African Environment

Opportunities

� World Wide Economic Growth and Technology

� Shifting from Engines to Engineering

� Power to be Always On, Always Available

� Africa is no exception

• Several possible solutions exist to :

Solution Options

- near centres of consumption

- power at a point, regardless of the major transmission and distribution power lines

� ensure the continuity of power supply

• Current “quick” solutions include generators.

• Africa has large potential for Solar, and in some countries, Hydro.

• Each solution has pro’s and con’s

• Hybrid solutions becoming relevant

Types of Solutions

• W.r.t generators, suppliers in Africa:

� Caterpillar

� General Electric

� Cummins

� MTU

� Volvo

� Perkins

� Hyundai

Generators

Fuel Sources

� Coal

� Biogas� Biofuels

� Methane (CH4)� HFO

� LPG� Petrol

� LNG (Natural Gas)� Diesel

GasFossil Fuels

• African Fuel Sources

Methane (CH4) Sources

• Methane (CH4) sources in Africa include

� Coal Bed and Mine Methane

� Underground Coal Gasification

� Landfill & Organic Waste Sites

� Water and Waste Treatment Facilities

� Livestock Manure

� Digester Plants

• Co-generation Opportunities

Fuel Quality and Storage

• Fuel Quality

� Poor diesel quality & contaminants

� System failure

Fuel Quality and Storage

• Fuel Storage

• Fuel Delivery

• Approvals

Solar

• Solar in Africa

� Many global solution providers

� Large solar installations feasibility stages

� Lack of knowledge & High initial capital cost

• Solutions include

� Grid tied systems to reduce grid feed

� Solar and Battery Backup

� Stand Alone Systems

Hydro

• Hydro in Africa

� Hydro plants exist throughout Africa.

� Not many are at full operational capacity

� Affected, seasonal rainfall and droughts

� Lack of skill, knowledge, and funds w.r.t

maintenance.

IPP’s

IPP’s - Independent Power Producers

� Opportunities exist

� Currently minimal significant purchasing

agreements are signed.

� Major challenge in Africa - transmission

� Most infrastructure grid and transmission

networks are not always available

IPP’s

IPP’s - Independent Power Producers

� If available – usually state owned

� Willingness to share / rent network not

forthcoming

� Power is seen as “Strategic”

� Strict controls imposed

� Many industries have ability to produce

� SA government – 10% from Private Sector

Funding

• Global Economic Crisis – No CAPEX

• Funding & Structured Finance solutions:

� Asset Backed Loans

� Finance and Operating Leases

� Dual funding from financial institutions & DFI’s

� Long Term Rentals

� Rental, Used, and New solutions

� Purchase power by kWhr

Skills

• Skills Shortage

� Developing local skills

� Training

� Knowledge Transfer

� Sustainability

� Support

Energy Efficiency

• Energy Efficiency and Power Conservation

• No more “Cheap” electrical power

• Energy Accord and Punitive Penalties

• Smart usage - result in cost savings

• Generators / alternative power no longer a

grudge purchase

• Tool to control peak demand costs and

provide risk insurance

Value Add

• Durability and Reliability

• Local backup and service w.r.t parts and

skills offered in Africa

• “Cheap” solution – normally minimal support

• Provider to understand local conditions

• Many solutions in African countries not

functioning at full capacity.

• “Cheapest” option is not always the “Best

Option” in the long run.

Sector Solutions

• Municipal Distribution & Utilities

� Interim or permanent on site power

alleviating current constraints.

� Complementary urban power generation

� Base line or peak supply, at key substations

� Assist in managing demand.

Sector Solutions

• Municipal Distribution & Utilities

� Leverage the proximity of water treatment

plants and landfill sites

� Generate power closer in the municipal power

distribution zone

� Use gas generated to run bio gas generator

sets or turbines.

� Technology successful in Europe

Sector Solutions

• Mining and Utilities

� Grid support power

� Stand alone power

• Key Installations

� Ring fencing of key installations

� Public, Commercial, Industrial, Manufacturing

� Supply dedicated prime, standby and

uninterruptible power solutions at all times.

Sector Solutions

• Telecommunications

� Network Stability Essential

� Information backup

� Improved reliability

� Sites require remote monitoring

� Solutions include batteries, Solar System,

Generators and Hybrid Solutions
