BACKGROUND

The 90 MW power Plant owned by Rabai Power Limited constitutes a significant investment in the future prosperity of Kenya. Being a major milestone in the Kenyan Government’s long-term energy plan which is aimed at regenerating the entire energy sector, the sponsors and developers behind the project, Burmeister & Wain Scandinavian Contractor A/S (BWSC) of Denmark and Aldwych International (Aldwych) of the United Kingdom aim at securing affordable and reliable power supply that meets Kenya’s increasing demand for electricity. The power Plant shall make an important contribution to the expanding economy of Kenya by providing a stable electricity source to the Kenyan households and businesses.

The prime movers of the power Plant consists of five 17 MW 18V46 Wärtsilä 4-stroke medium speed diesel engines each coupled to an alternator. The engines provide dependable power production and high availability ensuring optimal Plant performance. The heat energy, a by-product of the engines’ exhaust gases, is utilized to enhance the efficiency of the Plant. Steam generates from the exhaust gas in heat recovery boilers.  This steam is used both for heating requirements associated with fuel oil storage and treatment; and to drive a Steam Turbine Generator (STG), hence improving the overall efficiency of the Plant by increasing the capacity by approximately 8% “free” extra output as a result.
