When Governor Peter Mbah announced plans for a 660-megawatt coal-fired power plant in Enugu State, the proposal immediately triggered two opposing reactions. One side sees it as the rebirth of the old Coal City and a bold attempt to escape Nigeria’s chronic electricity paralysis. The other sees it as a dangerous bet on a fuel the rest of the world is gradually abandoning.
At the heart of the debate lies a brutal reality: Nigeria desperately needs power. Industries are collapsing under diesel costs. Manufacturers spend fortunes on self-generation. Small businesses die quietly under blackouts. In that context, a government promising uninterrupted electricity sounds revolutionary.
But the real question is not whether Enugu needs power.
It is whether coal is the right future for that power.
Why Enugu Is Looking at Coal
The decision is not accidental. Enugu’s history is literally tied to coal. The city itself rose around coal mining during the colonial era, earning the nickname “Coal City.” Large coal deposits remain in the region, and the state government argues that using a local resource to generate electricity is economically strategic.
Governor Mbah insists the state’s coal has low sulphur content and high calorific value, making it cleaner and more energy-dense than many global coal reserves. According to him, the government has spent nearly two years studying feasibility and securing coal assets before unveiling the project.
For Enugu, the attraction of coal comes down to five things:
Abundant local availability
Stable baseload electricity generation
Lower fuel import dependence
Potentially cheaper long-term electricity
Industrialisation ambitions tied to manufacturing growth.
It will not be subject to global fuel price volatility thereby adding stability to power generation.
Coal plants also provide what energy experts call “baseload power” — electricity that can run continuously for long hours without depending on weather conditions. Unlike solar or wind, coal plants do not shut down when clouds appear or winds slow.
To policymakers chasing industrialisation, that reliability is seductive.
Why Coal May Look Better Than Gas ,At Least on Paper
Nigeria possesses enormous gas reserves, so critics immediately ask: why not gas instead of coal?
The answer is complicated.
Gas power plants may be cleaner, but they are heavily dependent on pipelines and gas delivery infrastructure something Nigeria notoriously struggles with.
Pipelines are vandalised. Supply contracts fail. Gas producers sometimes prioritise exports over domestic supply. Several Nigerian gas plants today operate below capacity because they simply cannot get enough gas consistently.
Coal, by contrast, can be stockpiled on-site. Once mining and transportation chains are established, supply interruptions become less frequent.
Coal plants are also generally less sensitive to short-term fuel price volatility. Gas prices can fluctuate heavily depending on global energy markets. Coal, especially locally mined coal, can offer more predictable operational costs.
That is likely part of the calculation behind Enugu’s move.
Yet this is where the argument begins to crack.
The Technical Downfalls of Coal
Coal may provide steady electricity, but it comes with technical, environmental, financial, and geopolitical baggage.
The first problem is emissions.
Coal-fired plants release large amounts of: Carbon dioxide (CO₂), Sulphur dioxide Nitrogen oxides, particulate matter, Heavy metals like mercury
Even “clean coal” technologies do not eliminate pollution; they only reduce it at enormous cost.
A 660MW coal plant would become one of the largest single-point emitters of greenhouse gases in Nigeria. That matters because global finance is rapidly moving away from coal projects. Many international banks and climate funds now refuse to finance coal infrastructure altogether.
This creates a dangerous long-term risk:
Enugu may build a plant that becomes economically isolated in a world transitioning toward cleaner energy.
Coal Plants Are Expensive to Maintain
Supporters often focus on construction costs but ignore lifecycle realities.
Coal plants require:
Massive cooling systems
Ash disposal systems
Emission-control technologies
Continuous maintenance of boilers and turbines
Rail or trucking logistics for coal transport
Ash waste alone becomes a major environmental issue. Coal combustion produces fly ash and bottom ash containing toxic substances that can contaminate water and farmland if improperly managed.
Then comes water usage.
Coal plants consume huge volumes of water for cooling. In regions already facing climate stress and irregular rainfall patterns, that becomes another hidden pressure point.
Gas Has Its Own Advantages
Gas-fired plants are not perfect, but technically they offer several advantages over coal:
Faster construction
Gas plants are usually quicker to build than large coal facilities.
Lower emissions
Natural gas emits significantly less carbon dioxide and pollutants than coal.
Higher efficiency
Modern combined-cycle gas turbines can achieve higher thermal efficiencies.
Operational flexibility
Gas plants ramp up and down faster, making them better companions for renewable energy integration.
Easier global financing
Investors increasingly view gas as a “transition fuel” compared to coal.
So why not simply use gas?
Because Nigeria’s energy paradox remains unresolved: a country rich in gas still struggles to deliver gas reliably to domestic power plants.
That is the contradiction haunting the sector.
The Bigger Contradiction: The World Is Leaving Coal
The most controversial aspect of Enugu’s plan is timing.
While Enugu moves toward coal, much of the world is moving away from it.
Countries across Europe are shutting down coal stations. China, despite still using coal heavily, is aggressively expanding renewables and nuclear energy. Financial institutions increasingly blacklist coal projects.
Even African countries are facing mounting pressure to avoid new coal investments.
So Enugu risks building what could eventually become a stranded asset infrastructure that becomes politically, financially, or environmentally unsustainable before the end of its intended lifespan. That does not mean the project will fail.
It means the project may succeed technically while becoming problematic economically and environmentally over time.
The Political Logic Behind the Project
Politically, however, the move is understandable. Reliable electricity changes everything:
factories reopen
investors arrive
SMEs survive
technology hubs expand
employment rises
Governor Mbah appears to be pursuing an aggressive industrialisation strategy tied to electricity independence. His administration believes power is the foundation upon which the state’s $30 billion economic ambition rests.
In a country where federal electricity supply remains unstable, subnational governments are beginning to pursue their own energy ambitions after constitutional and electricity market reforms allowed states greater participation in power generation and distribution.
That is the broader significance of Enugu’s announcement:
it signals the rise of state-driven energy federalism in Nigeria.
Editorial Conclusion
Enugu’s proposed 660MW coal-fired plant is both visionary and controversial.
Visionary because it recognises a hard truth: no economy industrialises in darkness.
Controversial because it bets heavily on a fuel many nations now consider yesterday’s technology.
Coal may give Enugu stable electricity faster than Nigeria’s chaotic gas infrastructure currently can. But coal also drags along environmental liabilities, financing complications, public health concerns, and long-term sustainability questions.
The smartest path may not be coal versus gas.
It may be coal as a short-term industrial stabiliser while aggressively investing in:
gas infrastructure
solar generation
battery storage
transmission modernisation
cleaner hybrid energy systems
If Enugu builds this plant without parallel investments in cleaner technologies, the state risks solving today’s electricity crisis while creating tomorrow’s environmental and economic burden.
The Coal City may indeed rise again. But the real challenge is ensuring it does not rise with the smoke of the past attached to its future.
