Mainstream Energy Solutions Limited (MESL), operator of Nigeria’s largest hydropower plants, has partnered with Granville Energy (PTY) Limited to design, build, finance and operate a 100 megawatt (MW) floating solar power plant at the Kainji Hydropower Plant in Niger State.

The project, described as the first of its kind in Nigeria, is expected to complement the existing hydroelectric capacity at Kainji, support the country’s energy mix and reduce reliance on fossil fuels.
It also aligns with the Federal Government’s agenda to boost renewable energy adoption across the country, the company said.

Speaking at the memorandum of understanding (MoU) signing ceremony in Abuja, Chairman of the MESL Board, Col. Sani Bello (rtd), said the initiative marked a significant milestone in the company’s mission to transform Nigeria’s energy landscape.

“This pioneer project embodies our unwavering commitment to increasing power generation in Nigeria while promoting sustainable and environmentally friendly solutions.

“When fully operational, the project will provide thousands of Nigerian homes and businesses with clean, reliable energy, supporting economic development while minimizing environmental impact,” Bello said.

He noted that the partnership with Granville Energy represents a strong statement of MESL’s dedication to renewable energy, in line with its mission and corporate social responsibility (CSR) interventions.

According to him, the floating solar power plant will demonstrate how renewable technologies can work side-by-side with existing hydro infrastructure to deliver affordable power and strengthen Nigeria’s energy security.

The Managing Director of MESL, in an official press statement, also underscored the strategic importance of the project.

He explained that the plant will harness the potential of solar energy to complement hydro generation at Kainji, thereby boosting efficiency and ensuring a more reliable power supply for consumers.

The 100MW floating solar plant will become a model for future renewable energy projects in Nigeria, especially as the country intensifies efforts to diversify its power generation sources. With the bulk of electricity still dependent on natural gas, such projects are critical to reducing greenhouse gas emissions and achieving the government’s energy transition targets.

MESL currently operates the Kainji and Jebba hydropower plants, along with other facilities, which together contribute significantly to the national grid. The new solar initiative, in collaboration with Granville Energy, is expected to reinforce the company’s position as a key player in Nigeria’s energy transition.
