What We Do
Sources of Power
In Kenya, electricity is mainly generated from hydro, thermal and geothermal sources. Wind generation accounts for less than six megawatts of the installed capacity.
Currently, hydro power comprises over 60 percent of the installed capacity in Kenya and is sourced from various stations managed by the Kenya Electricity Generating Company (KenGen). Hydro power is generated by a process whereby mechanical energy produced by falling water is transformed into electrical energy.
Thermal electricity is produced by the burning of fuel (fossil, nuclear, biomass etc) to produce steam or gas which turns turbines that produce electricity. Geothermal electricity is generated from underground steam that is used to drive a conventional turbine to generate electricity.
Transmission and Distribution
Kenya Power is responsible for ensuring that there is adequate line capacity to maintain supply and quality of electricity across the country. The interconnected network of transmission and distribution lines covers about 47,035 kilometers.
- National grid
The national grid is operated as an integral network linked by a 220 kV and 132 kV transmission network. There is a limited length of 66 kV transmission lines. The national grid impacts on the future growth of the energy sector because any new generation capacity must take into consideration the existing network and its capacity to handle new loads.
Kenya Power reinforces the power transmission and distribution network by constructing additional lines and substations.
Efficiency of the transmission and distribution network continues to be enhanced in both technical and non-technical aspects. (See our annual report for more information on transmission system plans.) Technical improvements include re-conductoring of lines, installation of capacitors, and construction of additional feeders and substations. Non-technical improvements include introduction of electronic meters, improvement of meter reading accuracy, fraud control and resolution of billing anomalies.
- Supply and Demand of Electricity
Kenya Power has more than 2,038,635 customers who consumed over 6,341 gigawatt hours of electricity in the financial year 2010/11. During the year, the maximum daily electricity peak demand recorded was 1,232 MW.
