Battery energy storage systems (BESSs) are becoming a key part of Africa’s transition to renewable energy, as it helps make the power grid more stable, flexible and secure across a continent that is still facing infrastructure and policy challenges, says renewable-energy company Enel Green Power.

Battery systems are vital for connecting renewable sources, such as solar and wind, to national grids, with BESS technology providing the balancing power needed for renewables to meet increased electricity demand, without affecting grid reliability.

“Battery energy storage is no longer an optional add-on to renewables – it is the backbone of a strong, low-carbon energy system,” the company reports.

Through its programmes – such as Open Africa Power – and partnerships – with foundation in support of the just energy transition RES4Africa – the company is helping to develop skills and drive innovation to roll out BESS projects across Africa. These efforts aim to increase access to affordable, clean power while developing local knowledge and capacity in energy storage solutions.

However, Enel Green Power admits that scaling storage projects in Africa remains difficult, as one of the biggest barriers is the lack of clear and stable regulation, while high upfront costs and limited funding continue to slow progress.

In South Africa, access to the grid is still controlled by State-owned power utility Eskom, which slows grid connections for renewable projects.

“Enel Green Power supports the recent market reforms that would allow independent power producers to sell power directly and join electricity markets, opening the door for more investment in storage,” the company says in an official statement.

Blended Finance Models

Project financing is another challenge, especially in developing markets where funding is limited and project risks are perceived as high, says Enel Green Power.

To tackle this, it is using blended finance models and public–private partnerships to derisk projects and make them more affordable.

“Enel is exploring innovative financing tools that combine development funding with private investment,” the statement reads.

It adds that studies, supported by the Enel Foundation and RES4Africa, are helping to identify ways of reducing risks and designing financial tools suited to African markets, as “these steps are key to improving project bankability and attracting long-term investment”.

Beyond finance and policy issues, sustainability and battery life-cycle management are also central to Enel Green Power’s strategy. The company applies strict sustainability rules for its suppliers, ensuring that all batteries are recycled or reused once they reach the end of their life.

For example, projects, such as Europe’s battery-technology-focused BIG LEAP – which is supported by the Enel Foundation – are exploring second-life uses for old batteries.

“These projects help reduce waste, lower environmental impact and promote a circular economy,” Enel Green Power reports.

Digital technology is another important part of improving the performance and reliability of energy storage. The company says advanced digital tools for predictive maintenance and real-time monitoring help to detect problems early and improve uptime. These systems also help to lower costs and extend asset life.

Enel adds that BESSs plays a crucial role in stabilising weak or overloaded grids, especially in regions with poor transmission and distribution systems. By offering voltage support, frequency control and peak shaving, these systems help to prevent blackouts and balance power flow.

Enel Green Power’s renewable-storage projects in North Africa help to demonstrate that these systems can boost grid resilience, even in fragile networks.

Improving Energy Access

The company notes that off-grid and microgrid solutions are becoming popular for bringing power to remote areas and mining sites. Through its work with RES4Africa and the RES4Africa Technical and Vocational School, Enel Green Power is helping to train local technicians to design, build and maintain small-scale energy systems.

“These projects are not only improving energy access but also supporting local job creation and economic growth,” it reports.

Enel Green Power believes that lower lithium-ion battery prices and new long- duration storage technologies will accelerate the adoption of BESSs across Africa as these are becoming cheaper and easier to scale, which will allow for increased participation in new electricity markets and create new revenue opportunities.

The company is already exploring such business models in countries, such as South Africa, where paid grid services are starting to emerge, it notes, adding that Africa’s energy future depends on clear rules, better financing options, and using digital and sustainable design.

“Battery storage is the missing link that can make renewable energy reliable, affordable and accessible for all. If we align policy, finance and technology, Africa can leapfrog to a cleaner and more secure energy future,” the company concludes.
