Limbe Power Plant rehabilitation project

Power Plant rehabilitation project restores original capacity

Eneo Cameroon’s Limbe power plant could generate only about 40% of the installed total capacity of 80MW. Wärtsilä’s solution was a complete rehabilitation; a total overhaul of four Wärtsilä 18V46 engines and five alternators. The overhaul covered all critical auxiliaries, including the replacement and upgrade of radiator systems, as well as other auxiliaries. This rehabilitation means clear operational savings for the customer.


“Prior to the rehabilitation project, each of the five engines had power derates of about 3-5MW. We definitely needed to improve the performance of the plant.”

Mr. John Louis Batoko, South Grid Thermal Plants Subdirector at Generation Eneo.

    • Regaining full plant capacity (16.0MW power from each engine) after a severe decline in output
    • Overhauling five engines and a whole power plant in seven months
    • Complete customised power plant rehabilitation, including upgrade of auxiliaries to achieve 16.0MW engine output
    • Original total generation capacity of 80MW recovered, even ahead of schedule
    • Reliable engines and power stability
    • Savings through reduced fuel and lube oil consumption
    • Reduced air emissions
