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
Hydroelectric power in Ghana
•
The Akosombo Dam on the
Volta river generates 1000
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
2013 (UNIDO) and (ICSHP)
Sites under development in Ghana
• 9 sites
• 40 MW
• Average cost: 3000 USD/kW
• Bulb and Pelton turbines

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
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
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
