Landmark East African Sovereign Power Generation Facility
The Kenya Rabai 90MW Thermal Power Plant & Grid Substation is a premier sovereign energy infrastructure development constructed in Rabai, Kilifi County, near Mombasa, Republic of Kenya. Commissioned under national utility expansion plans with Kenya Power & Lighting Company (KPLC) and the Ministry of Energy, the project was engineered and executed by GY & Sons Holding in joint venture with international power engineering consortia to provide reliable baseload electricity to the Kenyan coast and national power grid.
Engineered to rigorous international utility reliability benchmarks, the plant comprises high-efficiency heavy thermal generation engines equipped with closed-circuit cooling systems, exhaust gas heat recovery, dual 10,000 m³ heavy fuel oil storage facilities, and an integrated 132kV high-voltage step-up switchyard connecting directly to the Mombasa–Nairobi national transmission corridor.
Gross Power Output
Continuous thermal baseload generation powering industries, coastal port logistics, and urban households.
High-Voltage Substation
Integrated step-up transformer substation and SF6 gas-insulated switchgear connected to the KPLC grid.
Fuel Storage Complex
Twin 10,000 m³ heavy fuel oil storage tanks with heating coils, fuel purifiers, and offloading manifolds.
Plant Availability
Demonstrated utility-grade availability factor supporting East Africa's economic development corridor.
