Olkaria II Power Station is Africa’s largest geothermal power station. It generates 70MWe and is the second geothermal plant owned and operated by Kenya Electricity Generating Company. The second phase of Olkaria II was commissioned in 2010 injecting an extra 35MWe of power, making a total of 150MWe of power produced through geothermal means.

On Thursday last week, KenGen shareholders visited the plant in Naivasha and were impressed by, among other things, the medicinal water that allegedly cures skin diseases at the Geothermal Health Spa. Olkaria II is efficient in steam utilisation. The wells were drilled between 1986 and 1993. In February, Well 37 A was established by Green Energy Group of India and it produces 4.2 MWe. It is still at the testing phase. It is experimental and the first of its kind in Africa.
