Africa’s Telecom Industry Accelerates Shift to Solar Power Amid Rising Diesel Costs
Rising diesel prices linked to the Iran conflict are intensifying an already ongoing transition across Africa, as telecommunications companies hasten efforts to convert cellphone towers from fossil fuels to solar power.
Diesel currently powers the majority of Africa’s approximately 500,000 telecommunications towers. In recent weeks, fuel markets have tightened following the Middle East conflict, making diesel more expensive and sometimes harder to secure. Several African nations heavily dependent on imported fuel have experienced price spikes and supply disruptions, prompting both governments and companies to reconsider their energy strategies.
“Diesel has always been a major cost, but recent global events have made it even more volatile,” explains Lande Abudu, senior energy specialist for Africa at GSMA, a global organization representing mobile operators. “That strengthens the case for solar and hybrid solutions.”
The economic argument for transitioning to solar has become increasingly compelling. Energy accounts for up to 60% of operating costs for telecom towers in off-grid areas. Once the default solution, diesel now presents challenges ranging from transport logistics to theft and maintenance issues.
Vodacom Africa reported that its energy costs rose 5% to $300 million in 2025 from the previous year, citing higher electricity tariffs and fuel prices. The company operates across multiple African countries including Egypt, South Africa, Congo, Mozambique, Tanzania, and Lesotho, with additional subsidiaries in Kenya and Ethiopia through Safaricom. Last year, Safaricom raised $153.6 million in green bonds specifically to help transition its towers to solar power.
In Nigeria, Africa’s most populous nation, cost pressures have intensified dramatically. The removal of fuel subsidies in 2023 triggered a surge in diesel prices of up to 200% within a year. Nigerian telecom operators now spend approximately $400 million annually just to keep towers operational. Recent global price increases tied to the Iran conflict have further exacerbated this pressure.
Companies are responding decisively to these challenges. Atlas Tower Kenya recently announced a $52.5 million investment to construct 300 new solar-powered telecommunication towers to serve major operators including Safaricom, Airtel, and Telkom Kenya. The firm currently has 82% of its 500 existing towers powered by solar energy.
Across the continent, mobile network operators are increasingly adopting hybrid systems that combine solar panels, battery storage, and limited diesel backup. Some companies aim for fully solar-powered sites over time, particularly in rural and off-grid areas where extending electricity grids would be prohibitively expensive.
The benefits extend beyond cost savings. Solar-powered towers have proven less vulnerable to fuel shortages and generator failures, improving reliability in underserved areas. In parts of northern Nigeria and Congo, cellular outages linked to fuel shortages have previously disrupted essential services ranging from mobile money transactions to emergency communications.
“By replacing diesel-powered telecom towers with fully solar-powered infrastructure, we expect to reduce the carbon emissions associated with mobile network operations,” said iSAT Africa CEO Rakesh Kukreja in March, when announcing new funding for clean energy tower projects.
Early results show significant savings. MTN operations in South Sudan have cut fuel spending by approximately 30% after adopting solar power. Meanwhile, Airtel Africa, working with ENGIE Energy Access, has reduced diesel use by more than half at sites in Zambia and Congo.
Africa’s reliance on diesel is particularly pronounced due to weaker grid infrastructure across much of the continent, making the shift both more challenging and potentially more transformative. However, regulators note that the transition could deliver broader benefits. In Nigeria, the telecom regulator has encouraged operators to integrate towers into solar minigrids that can also supply nearby communities.
“These telecom towers can act as anchor clients for solar minigrids, supplying electricity not only to the towers but also to nearby homes, businesses and public services,” said Aminu Maida, head of the Nigerian Communications Commission.
Replacing diesel generators with solar energy could help close Africa’s connectivity gap, where about 65% of people who could benefit from mobile internet remain unconnected, according to GSMA data.
In rural Kenya, residents in off-grid communities report that solar-powered towers have improved service stability, enabling more consistent access to mobile banking, education, and health information.
“Before this telecommunication mast was installed, we struggled to process mobile money payment or even call for help during medical emergencies,” said Martin Imwatok, a teacher in northern Kenya. “When these towers go off, business and life stop.”
As fuel prices remain uncertain amid global tensions, industry experts predict the case for cleaner energy will only grow stronger in the coming years.
“This is no longer just about climate,” Abudu notes. “It’s about resilience, cost and keeping Africa connected.”
