Africa’s renewable energy growth is moving into a new stage as countries across East, West, and Southern Africa rapidly expand solar power capacity. While solar installations are increasing, the main challenge is no longer generation but integration. Weak transmission networks, grid instability, and heavy reliance on diesel power are making it difficult to deliver reliable electricity. As a result, battery energy storage systems are becoming a core part of energy infrastructure rather than an optional addition.
In many African markets, energy storage is not used mainly for price trading or arbitrage. Instead, it plays a critical role in ensuring reliable power supply. Solar-plus-storage plants, hybrid microgrids, and grid support systems are being deployed to stabilize frequency, reduce power curtailment, and provide consistent electricity for households, businesses, and public services. Storage is also helping reduce diesel consumption, lowering fuel costs and emissions in remote and off-grid areas.
Africa’s operating conditions add further complexity to storage deployment. High temperatures, dust, and remote locations require systems that can operate safely and continuously with limited on-site support. This has increased demand for solutions that go beyond battery hardware to include system engineering, digital controls, and long-term operations and maintenance.
Developers and utilities are therefore shifting toward end-to-end storage solutions that integrate hardware, software, and lifecycle services. RelyEZ has structured its Africa strategy around this model, offering integrated project delivery as well as standalone equipment. Its portfolio includes the GridUltra containerized battery energy storage platform, the Venture Series of application-specific solutions, and an integrated Energy Management System.
GridUltra is designed for high-temperature environments and long-duration use, with liquid cooling, modular design, and enhanced safety features. The Venture Series builds on this platform to support different use cases such as utility-scale renewable integration, commercial and industrial backup power, and hybrid solar-storage-diesel microgrids. The company’s Energy Management System allows real-time monitoring and control, optimizing battery performance while supporting grid services like peak management and frequency stabilization.
Bankability and risk management are also becoming more important as storage projects rely on long-term financing. RelyEZ has received Tier-1 BESS classification and a BBB bankability rating, with insurance-backed warranties supported by Munich Re.
In Africa, RelyEZ is involved in projects focused on energy access and reliability. In Kenya, it is delivering hybrid solar-storage-diesel microgrids for nine remote villages under a government rural electrification program. In Burkina Faso, the company has secured an EPC project combining 40 MW of solar with a 10 MW/30 MWh battery system to improve grid stability in the Koudougou region.
As Africa’s energy transition continues, battery storage is emerging as a backbone technology. Integrated delivery models are expected to play a key role in building reliable and resilient power systems across the continent.
