Kenya Electricity Generating Company (KenGen) has issued a tender notice seeking “Expressions of Interest (EOI) for consulting services for the implementation of turbine uprating for Olkaria IV Unit 1&2, and Olkaria IAU Units 4&5 geothermal power plants in Olkaria, Kenya”
The Project Executing Agency (PEA) hereby invites qualified independent consultants to submit a pre-qualification document for required consulting services.
Funds have been earmarked for this project by the German bilateral Financial Cooperation, provided through KfW Development Bank. The prerequisites for disbursement are not yet finalised. Any contractual commitment related to this tender procedure is subject to the readiness of disbursement of funds.
As at January 2020, Kenya has developed 846.8MW of geothermal power out of a potential of over 10,000MW and is currently at position 7 in the world ranking. KenGen contribution to the national geothermal is 706.1MW mainly in the proven Olkaria Geothermal Field with at least 1000MW potential. KenGen power plants and their capacities currently include but are not limited to: Olkaria I – 45MW, Olkaria II-105MW, Olkaria IAU150MW, OlkariaIV-150MW , Wellheads – 83.5MW and Olkaria V-172.328MW. Additional plants, Olkaria I-Unit 6 (86.8MW) is currently under implementation stage while others are planned in Olkaria field over the next 5 years namely, Olkaria VI- 140MW, Olkaria VII-140MW and Modular power plants-50MW.
KenGen has applied for financing of the project from the KfW Bankengruppe (KfW) and intends to undertake uprating of Olkaria IV and Olkaria IAU 140 MW geothermal power plants in order to increase the power output and improve steam efficiency. The project entails: Upgrading the existing Olkaria IV units 1 & 2 steam turbines steam path to be able
to admit steam at a higher inlet pressure in order to increase the power output from
the current 75MWGross to 85MWGross Turbine/generator,
Upgrading the existing Olkaria I additional units 4 & 5 steam turbines steam path to
be able to admit steam at a higher inlet pressure in order to increase the power output from the current 75MWGross to 85MWGross Turbine/generator,
