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
• 5kVA – 100MVA Solutions
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
