Olkaria II went on-stream in 2003 when
Kenya Electricity Generating Company (KenGen) commissioned two 35 MW units manufactured and installed by
Mitsubishi Heavy Industries (MHI). In 2010, a third unit of 35 MW capacity was installed, at a cost of approximately US$100 million, bringing the total capacity to 105 Megawatts. The expansion was financed by (a) the
European Investment Bank, which lent US$40.8 million (KSh303 billion), the
International Development Association, which lent US$27.6 million (KSh2.2 billion), the
French Development Agency, which lent US$20 million (KSh1.6 billion) and KenGen, which contributed the balance. The Olkaria II power plant is one of six geothermal stations either planned or already operational in the Olkaria area in Nakuru County. ==Ownership==
