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.
