KenGen’s half year profit has dropped from 4.6 billion in 2016 to 4 billion in the six months ending December 31 2017. The power generator at the same time saw an increase in revenue from 17.7 billion to 18.6 billion, an increase of 4.93 percent. This was due to higher energy revenues from geothermal and increased steam revenue following the completion of the Olkaria-Suswa transmission line.
