Within the period of 2009 and 2014, KenGen implemented and commissioned the Ngong I and II wind projects with an installed capacity of 5.1 and 20.4MW respectively.

The Ngong Wind Farm is located on the Ngong Hills, near Ngong town in Kajiado County and is approximately 20 Kilometres from the capital, Nairobi.

The Ngong I plant consists of 6 Vestas V52-850 KW 50 Hz turbines while the Ngong II plant consists of 8 Vestas V52-850 KW 50 Hz turbines and 16 Gamesa turbines G52-850 KW 50HZ turbines. Total generated power of 25.5MW is evacuated via an 11/66 kV line to the Ngong Substation.

Plans are at advanced stage for the development of Ngong Phase 3 wind farm with an 18-month implementation period. Once completed, the project will add 10MW to the national grid. Also planned for development is the Ngong Phase 4 wind farm which will bring on-stream another 40MW at a cost of USD70 million.
