UK Government Unveils Clean Power 2030 Action Plan for Electricity Market Reform

Government opts for national pricing over regional zones

On 10 July 2025, the UK government announced major reforms to Great Britain’s electricity market. Energy Secretary Ed Miliband confirmed the country will keep its single national wholesale electricity price. The decision ends three years of debate about whether to split the country into regional pricing zones.

The Review of Electricity Market Arrangements (REMA) concluded that reformed national pricing offers the best route to a fairer and more affordable system. The changes aim to support the government’s Clean Power 2030 mission. They also seek to protect consumers from volatile fossil fuel prices while speeding up renewable energy deployment.

This marks a significant moment for UK energy policy. The government has chosen evolution over revolution. Instead of dividing the country into zones with different wholesale prices, it will modernise the existing model through targeted infrastructure and operational improvements.

How Britain’s electricity market reached this point

Great Britain has operated a single national wholesale price since 2005. That year, the British Electricity Trading and Transmission Arrangements (BETTA) unified England, Wales, and Scotland into one market. Before that, the New Electricity Trading Arrangements (NETA) came into force in 2001 following electricity privatisation.

The Electricity Market Reform package arrived in 2013. It introduced Contracts for Difference (CfDs) to support low-carbon generation. These mechanisms helped drive over £110 billion of investment in clean energy by 2020. However, they also created new challenges as the grid evolved.

The REMA process launched in 2022 to address mounting pressures. Renewable generation has grown rapidly, particularly offshore wind in Scotland and the North Sea. Unfortunately, much of this power generates far from where people use it. Consequently, the grid faces regular constraints that cost billions to manage.

Under national pricing, everyone pays the same wholesale rate regardless of location. This creates fairness in one sense. However, it also means constraint costs get spread across all consumers. The government explored zonal pricing as an alternative but ultimately rejected it due to investment risks.

Strategic planning takes centre stage in 2026

The centrepiece of the new approach is the Strategic Spatial Energy Plan (SSEP). The National Energy System Operator (NESO) will publish this plan in 2026 after consultation. The UK, Scottish, and Welsh governments commissioned it jointly in 2024.

The SSEP will map optimal locations for energy projects across land and sea through to 2050. This represents a fundamental shift in how Britain plans its energy infrastructure. Instead of reacting to project applications, the system will guide development to the most efficient locations from the start.

For businesses, this matters because it should reduce grid connection delays. Currently, projects can wait years in connection queues. The SSEP aims to align generation, storage, and network capacity more effectively. This should cut costs and speed up the transition to clean power.

NESO estimates the reforms could avoid up to £4 billion in constraint payments by 2030. These are the costs paid to wind farms and other generators to switch off when the grid cannot handle their output. Therefore, reducing these payments will directly benefit consumer bills.

Constraint costs drain billions from the system

Constraint payments have become a major issue as renewable capacity has grown. When wind farms in Scotland generate more power than local demand requires, the grid must either store it, transmit it south, or pay generators to curtail production. The third option happens far too often.

Grid infrastructure has not kept pace with renewable deployment. Transmission lines and interconnectors face capacity limits. As a result, National Grid ESO (now NESO) pays generators in the north to reduce output. It then pays gas plants in the south to increase generation to meet demand.

This inefficiency costs the system billions annually. The £4 billion saving target by 2030 depends on accelerating grid upgrades and better balancing mechanisms. However, these improvements require significant capital investment and planning reforms to succeed.

For manufacturers and energy-intensive businesses, constraint costs feed into overall system charges. Reducing them should help moderate price increases. Nevertheless, the benefits will only materialise if infrastructure delivery matches the ambition set out in the reforms.

Network charging reforms address regional differences

While wholesale prices remain national, the government plans changes to network charging. Currently, transmission charges vary by location to reflect the cost of connecting different areas. These charges can significantly affect business operating costs, particularly for heavy industry.

The reforms will review how these charges apply to ensure they send appropriate signals for new investment. For example, businesses locating near renewable generation sources might benefit from lower connection costs. Conversely, those in grid-constrained areas could face higher charges.

This creates a more nuanced approach than pure zonal pricing. Wholesale prices stay uniform across Britain. Meanwhile, network charges reflect actual infrastructure costs more accurately. The government believes this balance maintains investment certainty while improving efficiency.

Energy UK, the industry trade body, welcomed this clarity. The organisation noted that reformed national pricing modernises markets without creating the regional disparities that zonal pricing would have introduced. This stability matters for businesses planning long-term investments in clean energy.

What Ed Miliband said about the decision

Energy Secretary Ed Miliband framed the reforms as essential for energy security. He stated that building clean power at pace and scale remains the only way to protect Britain from fossil fuel market volatility. His comments emphasised protecting families and businesses from price shocks.

Miliband described reformed national pricing as the best way to deliver a fairer, more affordable, and more secure electricity system. This reflects the government’s broader Plan for Change, which prioritises clean power by 2030 as a foundation for economic growth and energy independence.

The announcement signals that energy policy will focus on delivery over further debate. After three years of REMA consultation, the government has chosen its path. Implementation now moves to NESO and industry bodies to execute the operational changes required.

Five essential points about the reforms

• The government announced the decision on 10 July 2025 through the Department for Energy Security and Net Zero, choosing reformed national pricing over zonal pricing after a three-year review.
• The Strategic Spatial Energy Plan will be published by NESO in 2026, mapping optimal energy project locations across Great Britain through to 2050 to reduce grid queues and system costs.
• Reforms could save up to £4 billion in avoidable constraint payments by 2030 through accelerated grid upgrades and improved balancing mechanisms.
• The single national wholesale price will remain, but network charging will be reformed to better reflect actual infrastructure costs and send appropriate investment signals.
• These changes build on the Electricity Market Reform package from 2013, which drove over £110 billion of clean energy investment by 2020 through Contracts for Difference and capacity markets.

Supply chain and procurement considerations for SMEs

For businesses involved in public sector supply chains, these reforms connect directly to procurement criteria. Government buyers increasingly require suppliers to demonstrate credible net-zero plans. Consequently, understanding electricity market reforms helps position your business competitively.

The shift towards clean power affects energy-intensive sectors particularly. Manufacturing, food processing, and logistics companies need to consider how their energy sourcing aligns with national policy direction. Power Purchase Agreements (PPAs) with renewable generators may become more attractive as the grid evolves.

Additionally, the SSEP will influence where new industrial facilities locate. Businesses planning expansion should monitor NESO’s spatial planning process. Locating near planned renewable generation or grid infrastructure could offer cost advantages through lower network charges and better supply security.

For smaller businesses, the key benefit should be price stability. National pricing prevents regional disparities that could disadvantage areas far from generation sources. Meanwhile, the drive to reduce constraint costs should moderate overall system charges over time.

However, this assumes infrastructure delivery meets targets. Delays in grid upgrades or SSEP implementation could undermine these benefits. Therefore, businesses should track progress through NESO updates and industry publications rather than assuming automatic improvement.

Compliance and reporting implications remain steady

The electricity market reforms do not directly change emissions reporting requirements. Businesses still need to measure and disclose their Scope 2 emissions from purchased electricity. Market-based accounting using supplier-specific emission factors continues alongside location-based reporting.

Nevertheless, the shift towards clean power by 2030 will affect your organisation’s carbon footprint. Grid emission intensity will fall as coal and gas generation decline. This creates a favourable trend for Scope 2 emissions even without changing your energy supplier.

For businesses pursuing net-zero commitments or responding to PPN 06/21 requirements, grid decarbonisation provides useful reductions. However, it does not eliminate the need for energy efficiency measures or renewable energy procurement. Credible climate plans still require demonstrated action beyond relying on grid improvements.

Our compliance support services help businesses navigate carbon reporting requirements and align energy strategy with net-zero targets. The market reforms create opportunities to strengthen your sustainability position if you act strategically rather than passively.

What this means for business energy costs

Predicting exact price impacts remains difficult because multiple factors affect electricity costs. However, the reforms aim to reduce system inefficiencies that currently inflate bills. Constraint payments, grid congestion, and balancing costs all feed into the final price businesses pay.

The £4 billion constraint saving by 2030 represents significant potential relief. Nevertheless, this benefit depends entirely on infrastructure delivery. Grid upgrades require planning consent, financing, and construction time. Past experience suggests these processes can face delays and cost overruns.

Maintaining national pricing protects businesses in southern England from potentially higher zonal prices. Under a zonal system, areas far from generation could have faced wholesale price premiums. Therefore, retaining the single price prevents regional competitive disadvantages.

Energy UK emphasised that stability and certainty matter for investment. Businesses planning energy-intensive operations or long-term supply contracts benefit from knowing the market structure will remain consistent. This reduces risk compared to the uncertainty that prolonged REMA debates created.

For practical planning, businesses should model scenarios that include both successful reform implementation and potential delays. The optimistic case sees falling costs from 2027 onwards. The pessimistic case involves continued high constraint costs if infrastructure lags. Most organisations should plan for outcomes somewhere between these extremes.

Grid infrastructure faces a critical test

The success of these reforms depends on physical infrastructure delivery. Britain’s transmission network needs substantial expansion to handle increasing renewable capacity. Offshore wind connections, interconnectors, and reinforced grid lines all require rapid buildout.

NESO inherits responsibility for coordinating this expansion alongside planning the SSEP. The organisation must balance multiple priorities including renewable integration, demand growth from electrification, and maintaining system stability. This represents a significant operational challenge.

Historical precedent offers mixed lessons. The BETTA unification in 2005 succeeded in creating a unified market. However, subsequent infrastructure investment lagged renewable deployment. This created the constraint cost problems that these reforms now attempt to solve.

The government’s commitment to accelerate planning reforms and grid investment suggests awareness of past failures. Nevertheless, delivery depends on coordination across multiple government departments, devolved administrations, and private sector developers. This complexity creates numerous potential failure points.

For businesses, the practical implication is monitoring progress rather than assuming success. NESO will publish regular updates on SSEP development and infrastructure delivery. These documents will provide early warning if implementation falls behind schedule.

Investment signals for clean energy projects

Retaining national pricing preserves investment certainty for renewable developers. Zonal pricing could have created regional price differentials that made some projects unviable. Consequently, the decision supports the government’s Clean Power 2030 target by maintaining stable conditions for capital deployment.

Contracts for Difference remain the primary support mechanism for new renewable capacity. The CfD system guarantees generators a fixed price for their output, protecting them from wholesale price volatility. This continues under the reformed market arrangements.

However, network charging reforms may shift where developers prefer to build projects. If charges better reflect actual grid connection costs, this could steer investment towards locations with available capacity. The SSEP will reinforce this by identifying preferred development areas.

For businesses considering on-site generation or storage, the reforms create a more predictable environment. Corporate PPAs with renewable generators benefit from stable wholesale market structures. Meanwhile, flexibility services that help balance the grid may become more valuable as renewable penetration increases.

Our net-zero programme helps businesses evaluate renewable energy options and develop strategies aligned with market developments. The reforms create opportunities for organisations that move strategically rather than waiting for perfect clarity.

Political and regulatory context matters

These reforms reflect the current government’s priorities around energy security and climate action. However, energy policy can shift with political changes. Businesses planning long-term investments should consider how robust these arrangements are across electoral cycles.

The decision to retain national pricing has broad support from industry bodies and consumer groups. This cross-party consensus suggests relative stability. Nevertheless, implementation challenges or cost overruns could revive debate about alternative approaches including zonal pricing.

Regulatory oversight comes from Ofgem, which must approve many implementing measures. The regulator balances multiple objectives including consumer protection, competition, and decarbonisation. Its decisions on network charging and market rules will shape how the reforms actually function.

Scotland’s devolved government has particular interest in these arrangements given the concentration of renewable generation north of the border. The SSEP process explicitly includes Scottish and Welsh governments to ensure territorial concerns are addressed. This collaborative approach reduces but does not eliminate potential for future disputes.
