The Greater Olkaria Geothermal Area is located in the Rift Valley about 120km from Nairobi. The field occupies an area of about 204KM² and the area currently under utilization is about 24KM². The estimated resource size is about 80KM².

 KenGen has been granted the license by the Government of Kenya to develop the Olkaria field which has an estimated potential of about 1200MW out of which, 155MW is developed and operated by KenGen and 52MW is developed and operated by Independent Power Producers (IPPs) leaving undeveloped resource potential of about 990MWe.

The Drilling Program
With funding from the Government of Kenya, KenGen commenced extensive drilling activities at the Olkaria field in 2006, and to date, a total of 63 wells with a steam capacity equivalent to 442.7MW have been drilled.

About 320MW equivalent of steam would be dedicated to the development of the 280MW of the Olkaria I Unit 4&5 and the Olkaria IV Project currently under construction and scheduled for commissioning in the year 2014.
A detailed drilling program for the development of the next phase of 560MW has been commenced and will be executed continuously until the year 2018.

The proposed 560MW Geothermal Project Pipeline KenGen plans to develop up to 560MW of Geothermal Power Plants at the Olkaria field in phases of 140MW each through Public Private Partnerships (PPP).
