Overview

The power station, owned by the Federal Government of Nigeria comprises six generation turbines, each with a rated capacity of 96.4 megawatts, for a maximum installed output of 578.4 megawatts. The concession agreement for operations and maintenance at this power station is held by ''Mainstream Energy Solutions Limited'', an independent power company. Mainstream Energy also holds the concession on the 760 megawatts Kainji Hydroelectric Power Station, located about . upstream of Jebba Power Station. Five of the generation units are available, as of January 2021. The sixth generation unit is inoperable, since it was damaged by a fire in April 2009.
