Mainstream Energy Solutions Limited (MESL), in a bid to advance the Nigerian energy landscape, has signed an agreement with Granville Energy (PTY) Limited to design, build, finance, and operate a 100 megawatt (MW) floating solar power plant at the Kainji hydro power plant.
Speaking during the signing ceremony in Abuja on Tuesday, Sani Bello, Chairman, Board of Directors, Mainstream Energy Solutions, said that the project is a significant step forward in the company’s mission to transform Nigeria’s energy landscape.
He explained that when fully operational, the project will provide thousands of Nigerian homes and businesses with clean, reliable energy, supporting economic development while minimising environmental impact.
‘We are proud to partner with Granville Energy (PTY) Limited to design, build, finance, and operate a 100MW floating solar power plant at the Kainji hydro power plant. This pioneer project embodies our unwavering commitment to increasing power generation in Nigeria while promoting sustainable and environmentally friendly solutions.
‘As an organisation. We have consistently demonstrated our commitment to renewable energy, aligning this with our mission statement and the focus areas of our Corporate Social Responsibility interventions. This MOU signing is a testament to our resolve to drive positive change and contribute to Nigeria’s economic growth.
‘This aligns perfectly with our core objective: powering Nigeria’s economic growth in an environmentally responsible manner,’ he said.
In his remarks, Abba Aliyu, Managing Director, Rural Electrification Agency (REA) noted that Nigeria currently have the highest number of people without electricity, with most of these people located in the rural and urban areas of the country.
For him, the most economically viable means of providing them with electricity is through distributed renewable energy, through the deployment of renewable sources.
‘For us to have an opportunity where 100 megawatts of renewable energy can be injected into the grid, for us, this is a huge and significant increase in the renewable mix of the country. I will say that apart from the Azura, which was 450 megawatts that was added as a Greenfield, and Zungeru, which mainstream is very much active in managing that, there is no significant renewable capacity that has been added to the grid.
‘Initially, the Rural Electrification Agency is currently working on injecting about 188.4 megawatts through interconnected mini-grids, one of which we intend to be the first to will do the floating solar in the University of Lagos, where we will put the panels by the side of the lagoon to power the University of Lagos.
‘But definitely, the commitment of the mainstream and the partners, Granville Energy, is something that the federal government will always have pleasure in and will always key into it.
He said that Nigeria needs to increase the generation capacity, hence the need to deploy more renewable resources and an innovative model like this that harnesses the space around the hydro and creates a floating solar.
He also advised the companies that the project should come with its own distribution network, SCADA system, and full meters to enhance the commercial viability of the project, adding that without these, the commercial viability of the renewable project can never be sustained.
‘This is an ingenious, complex framework that must be encouraged, and for the Rural Electrification Agency, we would like to be part of this initiative, key into it, support it, and in any way also learn from how we will do that, how we will deploy it at this level of capacity,’ he added.
Also speaking, Tabi T. Tabi, Chief Executive Officer, Granville Energy, said that the MOU commits both parties to the development of the Kainji Floating Solar Plant, which is intended to reach a total capacity of 1,000 megawatts (1 Gigawatt).
He explained that the immediate focus is the rapid deployment of phase one, which will add 100 MW of hybrid renewable power to the grid. ‘This multi-gigawatt vision is a testament to what is possible when two African giants-Nigeria and South Africa-collaborate,’ he said.
Tabi noted that by deploying high-efficiency solar panels directly onto the surface of the Kainji reservoir, the project will deliver a powerful hybrid system. This synergy, he said, ensures that when the sun shines brightest, it generates solar power; and when it sets, or when water flow fluctuates, the stabilised output of the hydro plant and the power from the battery energy storage systems step in, providing consistent, reliable power to the national grid.
‘Floating solar is a win for water management. By covering a section of the reservoir, we drastically reduce water evaporation-a critical benefit for a nation balancing energy production with agricultural and domestic water needs.
‘This first 100 MW phase is the down payment on a larger vision that will, upon completion, provide 1,000 MW of new, clean capacity, dramatically cutting carbon emissions and cementing Nigeria’s commitment to the goals of the Paris Agreement and its long-term climate targets,’ he said
