The United Kingdom is putting more than £2 million behind clean energy in Africa through the ZE-Gen Scale-up Fund and the UK Government’s Ayrton Fund. This support will power 10 projects across eight African countries. Together, they aim to replace diesel generators, bring reliable electricity to essential services and businesses, and help proven technologies move from pilot programmes into wider use. It’s a meaningful boost for Africa’s clean energy transition.
This programme is modest relative to Africa’s energy needs. Its importance lies less in its headline amount than in what it can demonstrate: whether targeted grants can help local energy businesses deliver dependable power, attract follow-on finance and improve livelihoods. The projects span Nigeria, Kenya, Uganda, Rwanda, Tanzania, Mozambique, Madagascar and Lesotho, covering solar-powered cold storage, hospital power systems, second-life batteries and hybrid mini-grids. Their shared challenge is making clean electricity reliable and affordable where grid service is weak, costly or unavailable.

Electricity access is not merely a household issue; it determines whether clinics can refrigerate vaccines, farmers can preserve produce, and small businesses can operate beyond daylight hours. The UN’s 2026 Energy Progress Report shows 655 million people still lack electricity, with 86% of the global access deficit concentrated in sub-Saharan Africa. IRENA confirms that about 33% of sub-Saharan Africa’s unelectrified population lives in West Africa, mostly in rural areas where grid extension is not economically viable. The sector’s scoreboard counts connections, but a connection is not access. 53% of sub-Saharan Africa has a grid connection, yet more than 560 million still live without reliable power.
In Nigeria, Farm Warehouse is deploying solar-powered cold-storage systems, while KAMIM Technologies is developing solar-powered agricultural hubs. Across sub-Saharan Africa, smallholder farmers lose 40 to 60 percent of perishable crops because there is nowhere to keep what they grow cool enough to reach market. Solar cold storage extends shelf life from around five days to as long as 21, enabling farmers to wait for fair prices rather than selling in a panic the day after harvest. Independent estimates suggest such systems could add more than US$10 million in seasonal income for Ghanaian farmers while cutting greenhouse gas emissions tied to food loss by around 15 percent.
In Kenya, SHIELD will provide clean-energy systems to power hospitals and reduce reliance on diesel. For health facilities, dependable electricity supports lighting, refrigeration, laboratory equipment and medical devices. MSF’s installation at Niafounké hospital in Mali illustrates the model: a 90 kWp solar system with 210 kWh lithium battery storage now covers around 60% of the hospital’s energy needs, significantly reducing dependence on a diesel plant prone to frequent outages. The hybrid system ensures continuity of vital care, including oxygen concentrators, surgical emergencies and blood transfusion cold chains.
In Uganda, Rwanda, Tanzania, Mozambique, Madagascar and Lesotho, the programme supports companies including AceOn, SLS Energy, Simusolar, Gommyr, Nanoé and Vittoria Technology. Second-life batteries can potentially reduce storage costs by reusing batteries that no longer meet original application demands but remain suitable for stationary storage. PREO’s 2026 report documents seven companies building viable second-life battery businesses, with models spanning battery testing, refurbishment, and Battery-as-a-Service. A pilot in Kenya found that adherence to IEC standards played a decisive role in mitigating technical risks, strengthening the economic case for solar-plus-storage solutions.
Mini-grids can serve communities distant from the national grid. IRENA’s 2026 report finds that solar PV mini-grids with battery storage represent a near-term market of 568 MW across Burkina Faso, Mali, Nigeria and Senegal, with approximately 397,270 settlements addressable by mini-grids. Nigeria accounts for almost 400 MW of this near-term capacity. The “value of storage” metric shows that for a typical community of 500 inhabitants, battery storage offers a discounted lifetime value of approximately $20,000, with fuel savings offsetting higher upfront investment.
Diesel generators are common where grid supply is absent or unreliable, but expose users to fuel-price volatility, transport costs and local air pollution. IRENA’s analysis shows that storage is a hedge against fuel-price shocks, with avoided fuel costs outweighing incremental investment by between two and four times. This is especially acute in landlocked countries where overland transport of fuel from coastal ports adds high cost and supply risk to every kilowatt-hour of diesel-based electricity.
The programme should be judged by durable results. Useful public indicators include operating hours and system uptime, diesel litres displaced, cost per unit of electricity delivered, number of farmers or patients served, changes in food spoilage or business income, maintenance costs, technicians trained, and follow-on finance secured. Nigeria’s experience offers a cautionary data point: evidence from solar systems installed in Nigerian Primary Health Care Centres indicates that more than 30 per cent become non-functional within three years of commissioning, with problems linked not to technology but to inadequate preventive maintenance, unavailable spare parts and unclear asset responsibility.
A clean-energy system can be technically successful and still fail if customers cannot pay for it. Tariffs, financing terms and payment schedules must reflect local incomes and the value users receive. For hospitals and other public facilities, governments must budget for maintenance and replacement parts. The IEC standards pilot in Kenya demonstrated that standards-based institutional electrification can improve learning environments and enable essential medical equipment operation, but emphasised that governance and end-of-life management are critical.
The programme’s stated goal is to move proven pilots into larger deployments. A pilot may work technically but fail to attract commercial investment if customers cannot afford the service, equipment is difficult to maintain, or revenue is uncertain. IRENA’s report recommends integrated electrification planning, enabling environments for mini-grids and storage, and innovative finance and de-risking mechanisms. Scale-up funding can help companies refine equipment, establish local supply chains, train technicians and demonstrate performance, but grants are not a substitute for a durable business model.
For Africa, the central lesson is that clean-energy deployment succeeds when technology is matched to local needs and supported by financing, maintenance, skills and accountable measurement. More than £2 million can support demonstrations and early commercial deployments, but it cannot by itself resolve Africa’s electricity-access gap.
The programme’s wider value will depend on whether it produces evidence that attracts additional public, private and development-finance investment. Solar panels and batteries are the hardware. The lasting outcome is whether farmers preserve more produce, hospitals maintain critical services, businesses operate more reliably, and communities receive power they can afford.
