NAIROBI – Rising diesel prices, influenced by the Iran conflict, are pushing Africa to embrace solar power for cellphone towers. Most of Africa’s 500,000 towers rely on diesel, which has become costlier and harder to find due to recent global market shifts. As prices soar and supplies dwindle, companies are urgently rethinking their energy strategies.
Traditionally, diesel has been the go-to fuel for these towers. However, the growing push towards solar energy, driven by both cost and climate goals, has gained momentum. The ongoing conflict has made companies reassess the risks associated with diesel dependence. “Diesel has always been a major cost, but recent global events have made it even more volatile,” said Lande Abudu, an energy expert at GSMA. “That strengthens the case for solar and hybrid solutions.”
Mobile operators are now increasingly turning to hybrid systems that blend solar panels, battery storage, and limited diesel use. This is especially crucial for rural areas where extending traditional electricity grids can be prohibitively expensive. There’s a noticeable trend in developed countries where most telecom towers are connected to reliable electricity networks. In contrast, Africa’s reliance on diesel puts operators at risk during supply shortages.
For instance, Atlas Tower Kenya is investing $52.5 million to build 300 solar-powered towers as part of a broader goal to reduce reliance on diesel. Currently, about 82% of their 500 towers are already solar-operated.
The financial arguments for switching to solar are robust. In some off-grid areas, energy costs can account for up to 60% of operational expenses. Major telecom players like Vodacom are already feeling the pinch. The company reported energy costs hitting $300 million in 2025, driven by rising fuel prices and electricity tariffs. In Nigeria, removing fuel subsidies triggered diesel prices to surge by 200% within a year, further squeezing budgets.
Amid these pressures, companies are now accelerating investments in clean energy. iSAT Africa is among those leading the charge, implementing solar-powered towers with innovative financing models. Early results are promising; MTN’s operations in South Sudan reported a 30% reduction in fuel costs after switching to solar.
Beyond financial benefits, solar towers improve service reliability. Solar systems reduce the risks tied to diesel shortages and generator failures, which can cripple services, particularly in underserved regions. In Nigeria and Congo, fuel-related outages have disrupted essential mobile services.
Recent user experiences underscore these improvements. Residents in rural Kenya have noticed better connectivity with solar towers, enabling smoother access to mobile banking and healthcare. “When these towers go off, business and life stop,” noted Martin Imwatok, a teacher in northern Kenya, emphasizing the critical role of stable telecommunications.
The shift from diesel to solar could also help narrow Africa’s connectivity gap. Currently, about 65% of individuals who could benefit from mobile internet remain unconnected. “Renewable energy systems enable faster and more cost-effective expansion into underserved areas,” Abudu highlighted.
This transition could also provide broader community benefits. In Nigeria, telecom regulators are encouraging operators to connect towers to solar minigrids that can supply power to nearby communities. Aminu Maida, head of the Nigerian Communications Commission, explained, “These telecom towers can act as anchor clients for solar minigrids.”
As global fuel prices continue to fluctuate, the case for cleaner energy in Africa only becomes stronger. “This is no longer just about climate,” Abudu concluded. “It’s about resilience, cost, and keeping Africa connected.”
