The project will use 16 G52 850kW turbines, designed for high wind conditions. It will be located 30 kilometres outside Nairobi and is being constructed by Kengen and Iberdrola.
The turbines will be delivered in Q1 2014, with the aim of bringing the project online in Q2 2014.
Kenya has just 5MW operating and although it is attempting to build the 310MW Lake Turkana project, this has been mired in funding and approval issues.
While South Africa and Ethiopia have pressed ahead to develop their wind capacity, progress in the rest of sub-Saharan Africa has remained patchy.
This is despite electricity prices being driven ever higher by expensive diesel imports and unprecedented growth in demand. The resulting power shortages continue to seriously constrain economic and social development.
