Privately-owned limited liability company
Activities in the power sector:
mini-hydro
solar power
gas-turbine

4. Electric power in Ghana
Current access to electricity is approx. 70% (2015)
A large proportion of the country has no power supply
Recurrent black-outs are a limiting factor for the industrial development
The Government offers support to private investors in the energy industry

5. Hydroelectric power in Ghana
The Akosombo Dam on the Volta river generates MW used mainly for the Al industry and for large cities
No small/mini hydro plants in Ghana at present
Many rivers have the potential for small hydropower development (<10 MW)
data from: World Small Hydropower development report (UNIDO) and (ICSHP)

6. Sites under development in Ghana
40 MW
Average cost: 3000 USD/kW
Bulb and Pelton turbines

9. Benefit of Mini hydro plant tecnology
Small single investment
Investments can be phased
Production can start within 1-2 years
Do not require highly specialised workforce
Local workforce can be used for construction and for maintenance
Low impact on the natural environment

10. Opportunities and Threats
New regulatory and legal framework for development and use of renewable energy source
Good economic incentives in place to attract investors to small hydropower
Elevated request of energy and drinkable water
Limited local technical expertise;
Lack of reliable technical data about the river (flow rate, rain etc.)
Cyclic droughts
Climate change

11. Local involvement
The Ministry of Energy will support the project with their technical staff
Local universities will be involved in the project
Programs will be developed to train local technicians on how to run and maintain the power plants
