Olkaria I Power Station
Olkaria I Power Station was the first geothermal power plant in Africa. The 45 MW plant was commissioned in three phases and has three units each generating 15MW of electricity. The first unit was commissioned in June 1981, the second and third units in November 1982 and March 1985, respectively.
To date, a total of 33 wells have been drilled for the station. Thirty-one of these are currently connected to the power station while two of these are retired. One well is currently being used for hot-injection. The turbines are direct condensing 4-stage running with an inlet steam pressure of 5 bars at temperatures of 152oC and steam consumption of 9.2 t/h/MW. The plant has had an average availability factor of over 95 per cent from commissioning. The power generated is connected to the national grid via a 132KV-transmission line.
