Mainstream Energy Solutions Limited (MESL)

Mainstream Energy Solutions Limited (MESL) was established in 2011 and licensed as a power-generating company. Through a concession agreement with the Federal Government of Nigeria, MESL acquired the Kainji and Jebba Hydro Plants (HPP) in November 2013, with a combined installed capacity of 1,338.4 MW. These two hydro plants are located 100 kilometers apart, with the Kainji dam positioned upstream of the Jebba plant.

The Kainji and Jebba hydro power plants have installed capacities of 760 MW and 578.4 MW, respectively. Kainji was commissioned as Nigeria’s first hydro power plant in 1968, while Jebba followed in 1985. These facilities are key components of Nigeria’s energy infrastructure and play a critical role in the nation’s electricity supply.
At the time of acquisition in 2013, the plants’ combined capacity was 482 MW, with Kainji non-operational. MESL has since restored their capacity to 1,002 MW, now contributing an average of 25% of Nigeria’s electricity. The company is managed by a seasoned Board of Directors and Executive Management team.
