GL Africa Energy chief executive Anders Langhorn has told African Energy that the 55MW expansion of the company’s Ndola heavy fuel oil (HFO) power plant in Zambia reached “substantial completion” on 30 January. The plant is in its final test and commissioning phase with reliability tests about to begin. The first 50MW at the Ndola power plant has been operating since November 2013 under a 15-year power purchase agreement, with six Wärtsilä 32 generators powered using HFO from the Indeni refinery.
