You cannot run an energy-intensive industry on good intentions. British steelmakers are currently staring down a brutal economic reality, grappling with an electricity price gap against European competitors that has widened to its worst position in three years.
The numbers tell a stark story. UK producers face power costs hovering around £90.5 per megawatt hour, while their French counterparts pay roughly £60.6. That stark £30 per megawatt-hour gulf isn't just a minor line item on a spreadsheet. It is a structural anchor dragging down domestic heavy manufacturing right when the country claims it wants to reindustrialize.
Why does this keep happening? The root cause sits in how the British energy grid is priced.
The wholesale price of electricity in the UK remains tightly coupled to gas. When geopolitical shocks flare up—such as the recent conflicts and supply disruptions in the Middle East driving global gas prices through the roof—the wholesale cost of power spikes across the board. It does not matter that a portion of the grid runs on cheap renewables; the market design dictates that gas sets the marginal price.
France sidesteps this structural trap largely because of its heavy reliance on nuclear power. Nuclear generation provides a steady, predictable baseline cost that insulates French manufacturers from wild fluctuations in international gas markets. Germany, meanwhile, still relies heavily on coal for industrial power, giving its heavy manufacturing a different set of trade-offs, though German steelmakers still secure an overall electricity price advantage over UK plants.
When you look at the breakdown provided by industry lobby group UK Steel, the baseline wholesale costs for British producers sit near £80.8 per MWh, dwarfing French wholesale figures. Even though past government policy changes removed certain policy add-ons and carbon charges to help industrial users, the raw mechanics of the power market leave UK plants competing with one hand tied behind their backs.
This disadvantage strikes at the heart of the national industrial strategy. You cannot build a modern green economy without steel. The transition to electric arc furnaces—which clean up the steelmaking process by recycling scrap metal instead of burning virgin coal—requires vast, reliable quantities of electricity. If powering those furnaces costs significantly more in Scunthorpe than it does across the Channel, capital will flee, plants will stutter, and domestic supply chains will wither.
Industry leaders argue that targeted price caps or direct state interventions are the only viable fixes left on the table. A proposed price cap scheme estimated at roughly £51 million annually would see the government cover the excess when wholesale prices spike, while the industry reimburses the state when prices drop. Critics point out the fiscal cost, but proponents counter that losing the domestic steel sector entirely carries a far heftier price tag in lost jobs, sovereign security, and economic resilience.
The government insists that recent relief measures and manufacturing support packages will trim bills for thousands of industrial businesses. Yet, on the ground, steel executives note that the gap with European rivals continues to stretch.
Fixing industrial power prices requires more than political slogans. Until the pricing mechanism decouples cheap renewable generation from volatile gas markets, British steel will continue to fight an uphill battle against continental rivals who enjoy cheaper, more stable power.
