Cormart Nigeria Limited has shifted its primary power source from diesel to natural gas, deploying five gas engines with a combined capacity of 5 megawatts across two operational sites in Lagos. The move positions the manufacturer—affiliated with Tropical General Investments Group—as a case study in how industrial companies can lower operating costs while cutting their carbon footprint in an environment of chronic electricity grid failures and volatile fuel pricing.
The company now operates 1.5MW of gas-fired generation at its Ilupeju head office, alongside 3.5MW at its production facility situated along the Lagos–Ibadan Expressway corridor. The previous diesel generating sets—a 2MW unit and a 3.1MW unit—have been retained solely for emergency backup duty.
According to Cormart's Technical Manager, Jawwad Alasa, the decision reflected hard operational economics. Energy expenses across Nigeria have climbed steeply, and manufacturers reliant on self-generated power have absorbed a disproportionate share of those increases. Integrating gas-fired generation with grid electricity has allowed the company to sustain output without sacrificing operational efficiency, Alasa explained.
The gas infrastructure is anchored by engines supplied and maintained under a service agreement with Clarke Energy, a specialist in distributed power generation. Grid connections and diesel generators remain in place as secondary layers, but the gas-first configuration now governs daily operations. Cormart noted that the arrangement prioritizes cleaner combustion and predictable fuel pricing against the volatility that has characterized diesel markets.
A recent service intervention illustrates the maturity of in-country support capabilities. Clarke Energy's Lagos workshop completed a minor overhaul on one engine unit after 40,000 hours of operation, returning it to optimal performance within a six-week window. The turnaround demonstrates growing technical capacity within Nigeria to service gas generation equipment without necessarily routing components overseas.
The company has also layered energy-efficiency measures into its operations, including steam-leak detection systems, routine energy audits, and upgraded lighting infrastructure. Together with the gas transition, these steps have contributed to more stable production and improved overall operational efficiency, according to Cormart.
Yiannis Tsantilas, Managing Director for Clarke Energy in Sub-Saharan Africa, framed Cormart's approach within broader food security and economic development objectives. Affordable food production depends on reliable and cost-competitive energy inputs, he noted, adding that adopting gas as an alternative to diesel supports both sustainability reporting requirements and the commercial viability of locally manufactured goods.
For multinational clients served by Cormart, the emissions reductions carry a relationship-management dimension. Export-oriented and multinational buyers increasingly factor supplier sustainability performance into procurement decisions, making energy transition credentials commercially relevant beyond cost savings alone.
Nigerian manufacturers broadly face an energy squeeze that combines grid unreliability with high diesel costs—a combination that makes self-generation a necessity rather than a preference. Cormart cited internal estimates placing self-generated power at 30–40 percent of total production costs, underscoring why fuel switching to gas represents a material bottom-line issue for the sector.
Broader adoption across the country, however, depends on pipeline and distribution infrastructure access. While Lagos benefits from relatively developed gas network coverage, manufacturers in other regions may encounter higher connection costs and longer lead times to secure gas supply. The model remains replicable where infrastructure exists, but infrastructure gaps limit the pace at which similar transitions can scale nationally.
