Power generated from the 2.2MW Gorge Farm AD plant will be sold to Kenya Power under a power purchase agreement (PPA).

Tropical Power managing director Johnnie McMillan said: "Distributed power projects are vital to Kenya’s energy security, reliability and efficiency, by generating electricity close to the point of use.

"Through biogas and solar, we want to displace expensive and imported generation fuels – like diesel and heavy fuel oil – from Kenya’s distributed power mix. The Gorge Farm AD Plant is physical proof that locally-produced feedstock can be used to generate clean and cost effective distributed power for all Kenyans."

Owned and managed by Biojoule Kenya, the $6.5m AD facility will make use of 50,000t of organic crop waste each year to produce at least 35,000t of nitrogen-rich matter as a by-product from the biogas process.

GE Africa Distributed Power leader George Njenga said: "This is the first AD project in sub-Saharan Africa for GE and it demonstrates how our Jenbacher gas engines can provide reliable and clean on-site power."
