Britain’s ambition to reach net zero emissions by 2050 is being stalled not by a shortage of commitment but by a tangle of high industrial power bills, market mechanics that let gas set prices even when renewables supply most electricity, and policy choices that create perverse incentives for companies. The result: manufacturers that must electrify to decarbonise are facing costs that sap cash for investment, nudge some toward fossil-fuel solutions and, in places, force firms to choose between saving energy and keeping vital subsidies. The squeeze is unfolding now as the government rolls out measures to ease bills while still wrestling with the structural problems that keep prices high.
Market mechanics raise the price floor
Britain generates a rising share of electricity from wind, solar and nuclear, yet wholesale prices are frequently set by the cost of gas-fired generation — the marginal unit called on to meet demand. That marginal pricing design means expensive gas can determine the market price for every half-hour trading period even when low-carbon sources supply the bulk of power, keeping the price floor well above what renewables’ running costs would imply. This coupling has left British industrial users paying some of the highest electricity rates among advanced economies, a charge that expert analyses say is a major barrier to industrial decarbonisation and competitiveness.
Beyond wholesale rates, levies and network charges tied to funding grid upgrades and renewable support are billed through electricity tariffs rather than general taxation. Those add-ons can account for a substantial slice of business bills and, because they are spread across consumers, raise the effective price paid by heavy industrial users. The government has recognised this pressure and proposed sharply increased discounts for the most electricity-intensive firms — a plan to raise relief for network charges — but those changes will take time to implement and do not resolve the underlying market linkage between gas and power prices.
Policy design creates perverse incentives
The way relief and subsidy thresholds are structured can perversely discourage efficiency. Several manufacturers have told officials they deliberately avoid cutting energy consumption below thresholds that would strip them of exemption schemes, because the loss of relief would overwhelm any savings. At the same time, temporary fiscal measures intended to limit excessive profits from some generators have added another layer of uncertainty for investors and operators in the clean energy sector. Those interventions were designed to protect consumers but also risk complicating the price signals that would otherwise steer investment into dispatchable low-carbon capacity.
Faced with bills that run into millions every month, companies say their strategic budgets are being dominated by energy management rather than technology upgrades. Firms able to qualify for targeted relief under industrial support packages track production and energy use meticulously to maintain eligibility; some have reconfigured processes, dimmed lighting and delayed capital spending because elevated power costs make low-carbon investments financially unrealistic. Others have considered the opposite — building on-site gas generation to avoid levies and network fees — a move that, while saving money in the short term, would lock in fossil infrastructure and jeopardise long-term decarbonisation. Those choices help explain why the transition from coal to renewables at the system level has yet to translate into rapid decarbonisation of heavy industry.
Britain’s net-zero roadmap envisions large increases in electrification: heat pumps for buildings, electric vehicles, and electrified industrial processes alongside a domestic supply chain of wind turbines, pylons, substations and batteries. But many of the firms that would make that equipment are themselves squeezed by energy costs and shrinking margins. When manufacturers cannot afford to invest in new plant, or choose to idle equipment during costly price spikes, the domestic industrial base that should deliver the clean-energy buildout weakens — slowing rollout of the very infrastructure that would lower long-run prices and enable faster decarbonisation.
Political tension between short-term fairness and long-term signals
Policymakers face a dilemma: act to reduce bills now to protect competitiveness and employment, or leave prices to reflect market realities so that long-term investors see the signals needed to finance clean capacity. Recent government announcements to trim levies and expand relief for energy-intensive industries aim to buy breathing space for manufacturers and limit the immediate damage to jobs and production. However, interventions that blunt price signals or introduce ad-hoc levies can discourage private capital from financing the flexible, low-carbon generation and storage needed to replace gas in the dispatch stack. That tension has created a policy environment in which firms and investors are reluctant to place large bets, slowing the transition.
The practical effects are visible across regions and sectors. Steelmakers operating electric arc furnaces cut output during price spikes; aluminium and foundry operations face monthly electricity spends that run into seven figures; and manufacturers that would otherwise install heat pumps or electrified processes calculate that running costs make those investments uneconomic today. Some global companies have flagged UK plants as having higher electricity costs than their overseas sites, raising the risk of offshoring or capacity loss if competitive gaps persist. Those micro decisions, taken thousands of times across the economy, aggregate into a meaningful slowdown in Britain’s capacity to reach net zero on schedule.
Industry and many policy analysts argue that a combination of measures is required: reforms to the wholesale pricing framework or alternative contracting arrangements that shield industries from extreme gas-driven price spikes; faster roll-out of low-cost, dispatchable low-carbon generation and storage to reduce reliance on gas; and a targeted, predictable support architecture that rewards efficiency without penalising firms that successfully cut consumption. The government’s pathway to a cleaner power system by 2030 and its net-zero target by 2050 provide overarching aims, but turning commitments into an operating environment that sustains industrial investment will require aligning market rules, fiscal design and network planning — and doing so quickly enough that the industrial base is not hollowed out in the meantime.
