Location
editThe facility is located in the Hell's Gate National Park along with its sister stations, Olkaria II and Olkaria III. This location lies in Olkaria, in Nakuru County, on the eastern edge of the Eastern Rift Valley, approximately 40 kilometres (25 mi), by road, southwest of Naivasha, the nearest large town.[3] Olkaria is approximately 121 kilometres (75 mi), by road, northwest of Nairobi.[4]
Overview
editOlkaria I Geothermal Power Station is one in a series of six geothermal power stations, clustered in the Olkaria area in Nakuru County. Four of the stations Olkaria I, Olkaria II, Olkaria III and Olkaria IV were operational, as of September 2017. As of 2020, the entire Olkaria complex had an installed capacity of 810.3 MW[5][6] Olkaria V is under construction and Olkaria VI is planned for 2021.[7]
History
editThe Olkaria I Power Station first started operation in 1981 running one Mitsubishi turbine with a generation capacity of 15MW. In 1982 and 1985, two more turbines identical to the first were commissioned at the facility, bringing the total generation capacity to 45MW.[8] As of January 2015 unit 4 and 5 with a combined installed capacity of 140 Megawatts were inaugurated.[9] This brings the total installed capacity of Olkaria I to 185 Megawatts.[2]
In March 2016, the government of Kenya borrowed KSh9.53 billion (US$95 million), from the Japan International Cooperation Agency (JICA) to refurbish turbines 1, 2 and 3 at Olkaria I. The works includes increasing the combined capacity of the three turbines from 45MW to 50.7MW. The rehabilitation and upgrade works are expected to last until 2021. This will increase capacity at this power station from 185 megawatts (248,000 hp) to 190.7 megawatts (255,700 hp).[10]
In December 2018, Kenya Electricity Generating Company broke ground for the construction of Unit 6 of Olkaria I Geothermal Power Station, with capacity of 83 megawatts. Completion of this unit was expected in 2021, bringing total capacity at this geothermal station to 268.3 megawatts (359,800 hp).[11] Unit 6 of Olkaria I, was commercially commissioned in July 2022.[1]
Ownership
editOlkaria I Power Station is owned by KenGen, a Nairobi Stock Exchange - listed company, in which the government of Kenya maintains 70 percent shareholding, the remaining 30 percent being held by institutional and private investors.[2][12]
