Unilever Tea Kenya Ltd. started as Brooke Bond Kenya. Tom Rutter, then in charge of Brooke Bond in Calcutta, India, during a hunting safari in Kenya in 1914, realised that the country was ideal for tea growing. Brooke Bond Kenya’s first major tea factory in Kenya was completed at Kerenga in 1927.
Hydroelectricity has played a major role in providing power for the tea production from the outset. Gilkes
provided their first turbine-generator units for the estate the year after it was completed in 1928. Three different hydro project locations have been developed over the years with Gilkes supplying a total of seven turbine-generator units.
Gilkes installed the Tagabi 2 turbine-generator equip-ment in an extension to the existing Tagabi project supplied in 1989.
Total Hydro Capacity: 2870 kW
*The Chemosit Project was supplied by Gilkes to another tea estate which was acquired by Brooke Bond Kenya as their tea production expanded
