Total Energies Inaugurates Africa's Biggest Hybrid Renewable Energy Project in South Africa

French energy giant, TotalEnergies has inaugurated Africa's largest hybrid renewable energy project in South Africa, marking a major milestone in the continent's shift towards cleaner electricity while helping strengthen one of Africa's most strained power systems.

Known as the Hydra project, the facility is located in South Africa's Northern Cape province and combines a 216-megawatt (MW) solar photovoltaic plant with a 500-megawatt-hour (MWh) battery energy storage system.

The project has been developed by a consortium comprising TotalEnergies (35%), Hydra Storage Holding (35%) and Reatile Renewables (30%).

Unlike conventional solar farms that generate electricity only when the sun shines, Hydra stores excess solar power in batteries, allowing electricity to be supplied for extended hours after sunset.

The facility will provide 75 MW of dispatchable renewable electricity to South Africa's national grid continuously between 5:00 a.m. and 9:30 p.m. under a 20-year power purchase agreement with Eskom.

According to TotalEnergies, the project will generate more than 400 gigawatt-hours (GWh) of electricity annually, enough to meet the electricity needs of about 200,000 South African households.

"This project reinforces our renewable production capacity in South Africa, the continent's largest power market in terms of electricity consumption," said Magali Pailhé, Managing Director of TotalEnergies Southern Africa.

She added that the project would strengthen South Africa's energy security while supporting efforts to decarbonise electricity generation.

The Hydra project goes beyond adding new renewable capacity. One of the biggest criticisms of solar energy is its intermittency: electricity production falls sharply after sunset, when demand often remains high. By integrating a large-scale battery storage system, Hydra can store daytime electricity and release it when needed, improving the reliability of renewable power.

The project is also among the largest battery-backed renewable facilities on the African continent, reflecting a broader shift in electricity investment from simply adding renewable generation to building systems capable of supplying power more consistently.

Hydra forms part of South Africa's Risk Mitigation Independent Power Producer Procurement Programme (RMIPPPP), introduced to attract private investment into electricity generation following years of power shortages and load shedding.

Although electricity supply has improved over the past year, South Africa continues to diversify its generation mix by adding renewable energy and storage to reduce dependence on its ageing coal-fired power stations while improving grid resilience.

For TotalEnergies, the project also strengthens its growing electricity business as the company expands beyond oil and gas into renewable energy and battery storage. The company said it now has nearly 36 gigawatts of gross renewable power generation capacity globally and is targeting more than 100 terawatt-hours of net electricity production by 2030.

The launch comes as countries across Africa race to expand electricity access while reducing carbon emissions. Battery-backed renewable projects such as Hydra could become increasingly important across the continent because they offer a way to improve electricity reliability without relying entirely on fossil-fuel generation. As more African governments seek private investment in clean energy, the project may serve as a model for future large-scale solar-and-storage developments.
