Africa continues to absorb the financial shockwaves of sustained geopolitical instability in the Gulf, with Brent crude prices whipsawing from $81 per barrel on March 3 to $112 on March 12 before settling back around $100 on March 25. For most of the world, crude volatility registers as an inconvenience. For Africa’s estimated 44 million small and medium-sized enterprises, it can be the difference between staying open and shutting down.
That is because across much of the continent, diesel has become the default energy source, not by choice but by necessity. Where grid infrastructure is unreliable, generators running on imported fuel fill the gap. When global oil markets tighten, African SMEs absorb the blow with little buffer. In this environment, coal-fired power generation is drawing renewed attention as a domestically available, potentially lower-cost alternative that could offer the fiscal breathing room these businesses so urgently need.
Rising Fuel Prices Squeeze African SMEs
The price surge has been sharp and indiscriminate. Nigerian fuel prices climbed to upwards of ₦1,000 per litre in March 2026, driven by pricing adjustments at the Dangote Refinery and broader swings in international crude markets. That represents a 39.5 percent increase since February, the second-largest monthly rise recorded globally. For a Nigerian manufacturer running diesel generators to compensate for the country’s chronic grid instability, the math has become punishing.
Zimbabwe is faring no better. Petrol prices have surged to $2.17 per litre while diesel stands at $2.05 per litre, placing Zimbabwe among the most expensive fuel markets in the SADC region and second-highest in Sub-Saharan Africa. Botswana faces the prospect of further price increases, while Uganda continues to experience location-by-location price swings that make forward planning nearly impossible for business owners reliant on fuel-generated power.
Even South Africa, the continent’s most industrialised economy, has seen businesses accelerate their shift to diesel as constrained grid capacity and persistent loadshedding erode confidence in centralised electricity supply. Supply disruption anxiety at the Strait of Hormuz has compounded an already difficult situation, adding a layer of geopolitical risk premium to fuels that small businesses cannot afford.

Coal’s Case for SME Competitiveness
The case for coal is, at its core, a case for energy sovereignty. Countries such as Nigeria, Zimbabwe, Botswana and Uganda all sit atop substantial domestic coal reserves. These resources, if properly developed and integrated into national power generation strategies, could reduce reliance on imported fuels and create a more predictable cost structure for local businesses.
According to the African Energy Chamber, Nigeria holds an estimated 9.8 billion cubic metres of coal reserves. Zimbabwe has documented reserves of 502 million cubic metres. Botswana, often overlooked in coal conversations, holds 1.6 billion cubic metres. Uganda’s reserves stand at around 800 million cubic metres. These are not marginal deposits; they represent a credible foundation for expanded domestic power generation that could materially alter the economics of doing business across the continent.
For SMEs, reliable and affordable electricity is not a luxury but a prerequisite for growth. Coal-fired power can offer a lower-cost baseload alternative that supports manufacturing continuity, enables longer planning horizons and reduces the vulnerability of small businesses to global supply shocks. Where many African governments are already integrating coal within broader energy diversification strategies, scaling generation and improving distribution infrastructure could translate directly into improved sovereign resilience and industrial competitiveness.
“When African businesses are being crushed by imported fuel costs, using domestic coal to keep factories running and SMEs alive is not a step backward but a rational act of economic self-defence.”
NJ Ayuk, Executive Chairman, African Energy Chamber
That framing of coal as economic pragmatism rather than ideological choice is increasingly the language that African policymakers and business leaders are adopting. The continent’s energy challenge is not abstract: it is felt in the daily operating costs of a Zimbabwean textile manufacturer, a Lagos food-processing plant running on generators or a Kampala printing house whose margins erode with every litre of diesel. Reframing coal’s role in terms of what it can do for those businesses, rather than what it means symbolically, is a necessary shift in conversation.
AEW 2026 Revives the Coal Debate
It is against this backdrop that African Energy Week (AEW): Invest in African Energies 2026 takes on particular significance. The annual event, which returns to Cape Town from October 12 to 16, 2026, has over successive editions created space for substantive, unideological discussions around coal’s place in Africa’s evolving power mix. Those conversations have grown more urgent, not less, as energy security, industrialisation and business affordability move back toward the centre of national policy agendas.
AEW 2026 is expected to host discussions examining the application of clean coal technologies, efficiency improvements in existing generation infrastructure, viable financing models for coal-fired projects and the specific sectors where coal-powered electricity can most directly support productive activity. The event provides a platform not for advocacy on coal’s behalf, but for rigorous analysis of where it fits within a realistic, Africa-specific energy strategy.
That distinction matters. The global energy debate has at times treated African coal discussions as anachronistic, a failure to absorb the lessons of the energy transition underway in Europe and North America. But Africa’s energy circumstances are materially different. Per-capita electricity access remains limited across large portions of the continent. Grid infrastructure, where it exists, is often unreliable. And the SMEs that generate employment and economic activity cannot wait for renewable buildout timelines that stretch years or decades into the future. In that context, coal is not a retreat but a response to immediate, tangible conditions on the ground.
African Energy Week 2026, Cape Town, South Africa · October 12–16, 2026. The continent’s leading energy investment event brings together policymakers, developers and industry leaders to debate Africa’s energy future across coal, gas, renewables and emerging technologies.
Coal will not solve Africa’s energy challenge on its own, and no serious analyst is suggesting otherwise. The continent needs a diversified power mix, one that draws on natural gas, renewables, nuclear and, yes, coal, in proportions that reflect the unique resource endowments, grid realities and development trajectories of individual nations. What AEW 2026 and the broader policy conversation are pushing back against is the idea that coal has no role at all, a position that, applied to Africa’s current energy conditions, would leave millions of small businesses exposed to precisely the kind of fuel-cost volatility that is already pushing some to the edge.
The question is not whether Africa should rely on coal indefinitely. The question is whether, in the near and medium term, domestic coal-fired generation can reduce the dependence of African SMEs on imported diesel, stabilise their power costs and create the conditions in which they can invest, hire and grow. On the evidence of current fuel prices across Nigeria, Zimbabwe, Botswana and Uganda, the answer deserves more than a dismissal.
