The Icelandic consulting firms ÍSOR, Mannvit, Vatnaskil and Verkís recently signed an agreement with Kenya Electricity, KenGen, for capacity assessment and feasibility study of the Olkaria geothermal fields. The agreement is the conclusion of an international tender procedure.
The Olkaria geothermal field is located in Kenya’s Rift Valley northwest of Nairobi south of Lake Naivasha. The utilization of the area began more than three decades ago and included consultation from Icelandic scientists and engineers. Currently there are three power stations in production totaling 200 MW. Plans for two 140 MW power plants are underway and KenGen anticipates that the harnessing capacity of the area is about 1000 MW. In comparison, the electrical capacity of the Hellisheiði Plant in Iceland is 300 MW.
ÍSOR and Vatnaskil will develop a model to simulate the behavior of the geothermal reservoir to estimate the future capacity of the area. Mannvit and Verkís will make a technical and economical assessment of the current power plants as well as further power plants to be constructed and an environmental report.
A local partner in Kenya is the consulting firm Armstrong and Duncan. The project has commenced and estimated time for completion is one year. Utilization of more geothermal fields is planned in Kenya and the Icelandic group is closely monitoring the process.
