Mainstream Energy Solutions Limited (MESL) has partnered with Granville Energy (Pty) Limited to design, finance, construct, and operate a 100-megawatt (MW) floating solar plant at the Kainji Hydropower Station in Niger State. The agreement was formalized during a signing ceremony in Abuja and marks a major milestone in Nigeria’s renewable energy landscape.
The hybrid project combines solar and hydropower technologies to enhance grid stability, expand electricity access, and support the nation’s clean energy transition.
Driving Nigeria’s Clean Energy Transition
Speaking at the event, Sani Bello, Chairman of MESL, described the initiative as a transformative step for Nigeria’s power sector.
“This 100 MW floating solar project embodies our commitment to increasing power generation while promoting environmentally and socially responsible energy. Once operational, it will supply clean and reliable electricity to thousands of Nigerian homes and businesses, powering economic growth in an eco-conscious manner.”
The project aligns with MESL’s renewable energy strategy and Corporate Social Responsibility objectives.
Government Support and Renewable Impact
Abba Aliyu, Managing Director of the Rural Electrification Agency (REA), highlighted the project as a key addition to Nigeria’s renewable energy portfolio.
“Distributed renewable energy is the most cost-effective way to provide electricity to underserved communities. The planned 100 MW floating solar facility will make a significant contribution to Nigeria’s renewable generation capacity.”
Aliyu emphasized the importance of integrating dedicated distribution networks, SCADA systems, and metering infrastructure to ensure commercial sustainability. He also noted that REA is working on deploying 188.4 MW of renewable power through interconnected mini-grids, including Nigeria’s first floating solar installation at the University of Lagos.
Pan-African Collaboration for Hybrid Energy
Tabi T. Tabi, CEO of Granville Energy, said the partnership represents the first phase of a long-term vision to scale the project to 1,000 MW (1 GW).
“Our immediate goal is to deploy the 100 MW phase quickly, integrating solar, hydro, and battery energy storage to improve system reliability. This collaboration between Nigeria and South Africa highlights the potential of African-led clean energy innovation.”
The floating solar system will employ high-efficiency panels on the Kainji reservoir, creating a hybrid system that balances generation between solar, hydro, and battery storage. Floating panels also reduce reservoir evaporation, supporting water conservation critical for both energy production and agriculture.
The full-scale 1,000 MW deployment is expected to substantially cut carbon emissions, reinforcing Nigeria’s commitment to the Paris Agreement and long-term climate goals.
