In May 2005, the Kenya Power & Lighting Company Ltd. (KPLC) called for tender for an Independent Power Producer (IPP) company to expand the thermal generating capacity in Kenya by 80 to 90 MW at Embakasi, Nairobi. 

BWSC, in consortium with Aldwych International Ltd., won the tender.

Due to proximity to the national airport in Nairobi and the logistic costs for fuel transportation, it was decided to retender the project, but this time with a new location at Rabai, Mombasa. Once more, BWSC, in consortium with Aldwych International Ltd., won the tender and was nominated preferred bidder in November 2006.

One of the other bidders challenged this award to the Procurement Board; the challenge was dismissed, but was then entered into the legal system. Finally, in October 2007, the case was dropped only to be followed by the disputed general election in Kenya in December 2007 which was followed by country-wide unrest.

At last, it was possible to close the financing against the backdrop of the worldwide financial crisis in the autumn of 2008.
