Rising Diesel Costs Threaten Telecom Investment and Network Reliability in Nigeria

By GLEBM News Desk

Nigeria’s telecommunications operators are facing renewed cost pressures following another increase in diesel prices, raising concerns that the expense of powering network infrastructure could constrain investment and affect service reliability.

The latest increase by Dangote Refinery took its ex-depot diesel price from ₦1,700 to ₦1,800 per litre on October 10. Other depot operators were reportedly selling the product at approximately ₦1,905 per litre, adding to the operating costs of companies that rely heavily on diesel-powered generators.

The development is significant for telecommunications providers because mobile networks require continuous power to operate base stations, transmission equipment, data centres and other critical infrastructure. Where public electricity supply is unreliable, operators must provide their own backup power to maintain service.

The scale of this dependence is substantial. Figures cited from the Africa Finance Corporation’s State of Africa’s Infrastructure Report 2025 indicate that Nigerian telecommunications operators consume more than 40 million litres of diesel monthly, with annual spending exceeding $350 million.

The sector is therefore exposed to fluctuations in fuel prices, which can affect operating margins and reduce the funds available for expanding network coverage, improving internet speeds and upgrading equipment.

MTN Nigeria had previously warned that diesel prices averaging ₦2,000 per litre in the second half of 2026 could have a financial impact of between ₦120 billion and ₦140 billion on its full-year earnings. The warning illustrates how energy costs can become a major financial burden even as demand for telecommunications services continues to grow.

The pressure extends beyond the purchase price of fuel. Operators must also pay for transporting diesel to geographically dispersed sites, maintaining generators, replacing batteries and securing equipment against theft and vandalism. Remote and rural locations can be particularly expensive to service because of poor road access, security concerns and limited grid connectivity.

These expenses could complicate efforts to expand broadband access and improve network capacity. If a growing proportion of revenue is absorbed by energy costs, operators may have fewer resources for infrastructure upgrades and the extension of services to underserved communities.

Consumers could also face indirect consequences. Higher operating costs may increase pressure for tariff adjustments, although any changes would remain subject to the applicable regulatory framework. More expensive telecommunications services would affect households, small businesses and organisations that rely on mobile data, electronic payments and online commerce.

Operators have been exploring solar power, battery storage, natural gas and hybrid energy systems to reduce their dependence on diesel. However, these alternatives require substantial upfront investment, and their effectiveness varies according to location and energy demand.

Improving electricity supply remains a key part of the long-term solution. More reliable grid power, better access to alternative energy and investment incentives could reduce the cost of operating telecommunications infrastructure.

The latest diesel increase highlights a broader economic challenge: energy costs affect not only fuel users and manufacturers but also the digital infrastructure on which businesses, financial services, education and public services increasingly depend. Sustained relief will require both more efficient power solutions and a more reliable electricity supply.
