Consultancy services sought for FPV on Kamburu hydropower reservoir

Kenya Electricity Generating Company (KenGen), Kenya's state power producer, intends to engage the services of a consultant to carry out a detailed feasibility study for development of a 40 MWp floating solar PV (FPV) plant on the reservoir of the Kamburu hydropower plant on the Tana River, which straddles the borders of Embu and Machakos Counties in the country's Eastern Province. The 93 MW Kamburu station, part of the Seven Forks Scheme, was commissioned in 1975.

An Invitation for Prequalification launched on 14 November invites sealed bids by 15 December. The contracted services are to be financed by the Government of Germany through KfW Development Bank (KfW). The findings of the feasibility study should be detailed enough to form the basis for project financing by the KfW, World Bank, AFD or any other financiers and to initiate negotiations for a Power Purchase Agreement (PPA). The feasibility study shall include, but not be limited to (i) Project start with kick-off meeting; (ii) Data collection, review of previous studies and site visits; (iii) Hydrological, sedimentation and bathymetric survey; (IV) Water flow, water quality and waves height analysis; (v) Computational fluid dynamics for wind flow analysis; (vi) Geotechnical study and preliminary topographical field investigations; (viii) Conceptual design; (IX) Transmission line, battery storage and grid connection study; (x) Economic and financial analysis; (xi) Risk analysis and mitigation, (xii) Project schedules and (xiii) Environmental and Social Impact Scoping Study.

The services are expected to be completed within eight months from the date of commencement of the assignment. A pre-feasibility study carried out in 2020 for floating solar on three of KenGen’s hydropower reservoirs – Kamburu, Turkwel and Kiambere – recommended a 40 MWp FPV array on the Kamburu reservoir due to the minimal water level variation, less design complication, good infrastructure (road network and grid), lower O&M costs and lower permitting costs due to ownership by KenGen. The Kamburu reservoir covers a surface area of 15 km2 at FSL and has a total storage capacity of 1.5 x 108, a useful capacity of 1.23 x 108 and a water level range of 16 m. KenGen is also developing a pilot 40 MWp ground-mounted solar PV array, adjacent to Kamburu.
