The company is now seeking bids for the proposed projects.
By 2017, Kenya aims to boost power generation capacity by 5,000MW from the current 1,664MW in order to reduce tariffs and business cost, reports Reuters.
The country is expected to need approximately 15,000MW of additional capacity by 2030 and most of the power would be generated from geothermal and other renewable resources.
Among the projects under construction include 140 MW Olkaria V power plant as well as 70MW plant in Olkaria I unit 6.
The company, which is 70% state-owned, is negotiating with development institutions seeking finance for the 140MW power plant.
Kenya has the potential to produce 7,000MW from geothermal and intends to produce at least 5,000MW of geothermal power by 2030.
KenGen, the electric power generation company in Kenya, generates approximately 80% of electricity consumed in the country.
