The UK government is actively exploring a shift from the current national energy pricing system to a zonal energy pricing model, which would see electricity priced differently across the country based on local supply and demand dynamics. While some industry voices support the move as a way to modernise the grid and better reflect regional differences, others warn of potentially severe consequences – particularly for consumers, businesses, and regions with higher demand and lower renewable output.
What Is Zonal Energy Pricing?
Under the current system, electricity prices are uniform across Great Britain, regardless of where power is generated or consumed. This model supports equitable access to energy and simplifies procurement for suppliers and businesses alike.
Zonal energy pricing, however, would segment the country into distinct pricing regions. Each zone’s electricity cost would be determined by the local availability of energy and transmission constraints. Areas with high renewable generation – such as Scotland – could see lower prices, while those in the South East and London, with higher consumption and limited local generation, may face significantly higher costs.
Rationale Behind the Proposal
Supporters of zonal energy pricing argue that the current system fails to incentivise efficient grid use. Renewable energy, particularly wind from Scotland, is often curtailed due to limited transmission capacity. This results in high constraint costs, estimated to reach £3 billion a year, paid by consumers to compensate generators for turning off clean energy.
Advocates believe zonal energy pricing would encourage energy-intensive industries to relocate closer to areas of abundant renewable generation. It could also reduce the need for costly upgrades to the national grid by better aligning consumption patterns with local generation. In theory, this would help achieve the UK’s net zero goals more efficiently.
Risks and Regional Disparities
However, critics caution against a rushed implementation of such a major structural change. A key concern is the potential for regional economic inequality. Consumers and businesses in southern England could see substantial energy price increases, affecting competitiveness, affordability, and investment.
The disparity in energy costs between regions may discourage investment in areas already grappling with higher operational expenses, while exacerbating the north-south economic divide. Further, there is concern about the impact on consumers who cannot easily relocate or adjust their energy usage. Households and small businesses in higher-cost zones could face steeper bills without viable alternatives.
Political and Industry Tensions
Despite the urgency for zonal energy pricing expressed by some, experts say it isn’t something that can be rolled out quickly. Cornwall Insight, have said the system likely wouldn’t be workable until the 2030s. The reforms required are complex, and the industry, regulators, and grid infrastructure all need time to adapt. This means that even if the decision to go ahead is made soon, the benefits may not be felt for years – while uncertainty and regional imbalances could emerge much sooner.
The Labour Party has expressed opposition to the current zonal pricing approach, fearing it could drive up household bills in parts of the country already facing affordability challenges. Some officials worry the proposal is being driven more by policy ambition than by sound economic planning.
Meanwhile, the renewable energy sector is split. Some developers welcome the signal it sends to build generation capacity closer to where it’s needed. Others fear it could complicate project financing if price volatility and location risks are not adequately addressed.
Industry Outlook and Next Steps
The government is expected to make a decision on zonal pricing later this year as part of broader electricity market reforms. Industry stakeholders are urging policymakers to consider the full range of implications, including social equity, business competitiveness, and the practical challenges of implementing a more complex pricing system.
It’s likely that if zonal pricing is introduced, it will be phased in gradually, with a transition plan to support affected regions and industries. Clear communication, detailed modelling, and robust stakeholder engagement will be essential to ensure a smooth rollout.
The debate around zonal energy pricing highlights the tension between efficiency and equity in energy reform. While the potential benefits of reduced grid constraint costs and better alignment of supply and demand are significant, the risks – particularly to consumers and regions with higher demand – are equally serious.
Businesses should begin scenario planning for potential regional price changes and consider how future reforms could impact their energy procurement strategies. Staying informed and adaptable will be critical as the UK charts the next stage of its energy transition. If you’d like expert advice regarding this ongoing, don’t hesitate to contact one of our team.
