The 90 MW Thermal Power Plant (TPP) owned by Rabai Power Limited constitutes a significant investment in the future prosperity of Kenya. With a capacity to provide power for 400,000 Kenyan Consumers, the Plant remains a key strategic Infrastructure investment into the Kenyan Electrical Generation system. The prime movers of the Power Plant are five 17 MW W18V46 4-stroke medium speed diesel engines in a combined cycle set-up, whereby the heat retained within the exhaust gasses are reused to produce steam in a Waste Heat Recovery Plant. Through a Steam Turbine (STG) “free” energy to 18,000 Kenyan consumers are produced, leaving Rabai Power as the most efficient TPP in Kenya.

Rabai Power Plant has a total capacity of approximately 90 MW, the major equipment comprising:

• 5 x Wärtsilä 18V46C reciprocating diesel engines: 17.4 MW, 500 rpm
• 5 x ABB AMG 1600 air-cooled generators: 21.3 MVA, 11 kV
• 5 x Aalborg (Alfa Laval) Waste Heat Recovery Steam Boilers: 11.8 kg/s, 13.5 bar, 365ºC
• 1 x Dresser Rand (Peter Brotherhood) Condensing Steam Turbine: 7.85 MW
• 1 x Bronswerk Air Cooled Condenser:
• 2 x Areva Step-Up Transformers: 75 MVA, 132/11 kV
• 3 x 4,500 M³ HFO Storage Tanks
