Africa's renewable energy surge accelerates with fast-built solar, wind, and storage projects

Africa’s power sector is being reshaped by a wave of solar, wind and battery projects as governments and investors increasingly favour technologies that can be built faster, financed more flexibly and brought online at lower cost than coal or large hydropower schemes.

The direction of travel is clear in the project pipeline. Electron Intelligence says 173 of the 322 energy projects announced across Africa in 2025 were solar, compared with 46 hydropower developments, 34 wind projects, 22 gas schemes and 14 hybrid projects. That tilt towards renewables reflects a wider recalibration of energy strategy across the continent, where reliability, affordability and speed to market now matter as much as raw generating capacity.

Industry figures point to accelerating momentum. The International Renewable Energy Agency says Africa added a record 11.3 gigawatts of renewable capacity in 2025, with South Africa, Egypt and Ethiopia accounting for much of the increase. Separate IRENA data also indicate that solar drove around three-quarters of global renewable capacity growth last year, underlining the technology’s central role in the current build-out.

For many developers, the appeal is not only environmental but commercial. Utility-scale solar prices have fallen sharply over the past decade, while onshore wind has also become markedly cheaper, making both technologies among the most competitive sources of new electricity in many African markets. Matt Tilleard, chief executive of CrossBoundary Energy, said renewables have become “the fastest, cheapest, and most bankable way” to connect businesses and economies to new power.

That shift is especially visible in distributed energy. Instead of waiting for national grids to expand, companies are increasingly installing solar and battery systems at mines, factories, telecom sites and homes. Tilleard argued that this part of the transition is often undercounted because official statistics still focus on grid connections, even though batteries and rooftop or captive solar can deliver power without central utilities.

Large industrial users are among the strongest drivers of demand. CrossBoundary Energy is developing a 233-megawatt solar and battery project for the Kamoa-Kakula copper complex in the Democratic Republic of Congo, one of Africa’s largest mines. Other reporting has described the scheme as a 222MWp solar plant paired with 526MWh of storage, with Germany’s Soventix joining the project earlier this year. The pace of execution is part of the attraction: projects of this kind can reach revenue far faster than coal plants or major dams, which often take many years to complete.

Developers are also betting on new business models. In South Africa, SOLA Group brought the Springbok Solar Power Project into early commercial operation in October 2025, describing it as the continent’s first multi-buyer flexible wheeling project. In January, the African Development Bank and PowerGen Renewable Energy launched a platform aimed at deploying 120MW of renewable generation and storage across Africa, with the potential to serve nearly 70,000 households. In Chad, Qair started building two hybrid solar plants with storage in N’Djamena, showing how battery-backed systems are spreading beyond the best-established markets.

Even so, the transition remains constrained by finance. Many utilities remain financially weak, making long-term power purchase agreements harder to underwrite. The International Energy Agency says borrowing costs for renewable projects in Africa can be up to three times higher than in advanced economies because of perceived country risk. Development finance institutions, including the African Development Bank and the International Finance Corporation, are stepping in with concessional lending, guarantees and risk-sharing structures.

The policy backdrop is also improving in some markets. Ethiopia’s ban on imports of internal combustion engine vehicles has helped support wider electrification efforts, while South Africa’s easing of limits on private power generation has opened the door to more industrial renewable projects. Yet the central challenge remains the same: translating abundant resource potential into bankable projects at scale.

As FSD Kenya’s Mugwe Manga put it, the issue is no longer whether the technology works. The harder task is mobilising capital, building political support and preparing projects that can be financed and delivered quickly enough to meet Africa’s growing demand for power.
