KenGen seeks Francis turbine runners for Kamburu

Kenya Electricity Generating Company (KenGen), Kenya’s state power producer, invites sealed bids by 27 February from eligible candidates to design, manufacture, deliver, install, test and commission two Francis turbine runners for the 94.2 MW Kamburu hydropower station on the river Tana.

The scope of works shall include inspection of equipment at site, detailed design and engineering, performance of CFD analysis and design reviews with the client, manufacturing of equipment, transportation and delivery to site, installation, site acceptance tests and commissioning, obligations in the 24 months guarantee period, training, documentation and warranty. All the works and equipment that are necessary for the execution of the project at site shall be the responsibility of the contractor. Tendering will be conducted under open competitive method using a standardized tender document.

Commissioned in 1973 to 74, the Kamburu station, which is situated about 180 km northeast of Nairobi, comprises three 31.4 MW vertical Francis turbines. The three units were rehabilitated from 2018 to 2019, including installation of new stainless-steel guide vanes with clutches, installation of new cooling system, upgrade of the excitation system, rewinding of the stator and installation of new rotor poles, installation of new 415V switchgear and servicing of the three main inlet valves. The station is currently running on second generation runners, the initial ones having been replaced due to extensive cavitation and frequent runner blade cracking. The current turbine runners, especially of Units 1 and 2 still experience frequent runner cracking at the crown. Unit 3 runner has not been experiencing the same phenomenon but has had some cavitation signs. In situ repairs have not been able to eliminate the problems and the units have to be stopped repeatedly for the works.
