Mainstream Energy Solutions Limited(MESL) operates two separate Hydro Generation Plants both drawing water from the same source, Niger River. The two Hydroelectric Power Plants, Kainji and Jebba have an installed capacity of 760MW and 578.4MW respectively. Kainji began operations as Nigeria’s first Hydro Power Plant in 1968. Located downstream from Kainji is the Jebba Power Plant which was commissioned in 1985. The turbines in the Power Plants are Kaplan adjustable and fixed blade types.
Mainstream Energy Solutions Limited has a strong commitment to renewable energy development to protect the environment and public health and help reduce emissions that cause climate change, while ensuring a system of diversity and security in electricity supply. Our renewable energy development programme is one of the most constructive, cost effective ways to address the challenges of high energy prices, energy security, air pollution, and global climate change.
Our Hydroelectric Power Plants generate on average 18 percent of Nigeria's power.
The feasibility study of both Kainji and Jebba dams started in 1952 and was concluded in 1962. The construction of Kainji dam commenced in 1964 and was completed in 1968. The dam was impounded in 1968, with a surface area of 1228.8km2 at full supply level of 141.73m. It has a gross storage volume of 15 Billion cubic metres and a live/usable storage of 12 Billion cubic metres.
The length of the reservoir is 136km from the dam axis to beyond Yauri in Kebbi state, while the widest portion at Shagunu is 24.50km.
Jebba dam was impounded in 1983, with a surface area of 316.50km2 at full supply level of 103.00m. The length of the reservoir is approximately 100km from Jebba dam axis to Kainji dam. The widest portion of the reservoir is 2.5km. Jebba reservoir is a relatively small one. It is about one quarter of the size of Kainji Lake. It has gross storage volume of 3.880 Billion cubic metres and a live storage of 1.00 Billion cubic metres. Read More
