Economy Minister Dr Caoimhe Archibald has published the Final Scheme Design for Northern Ireland’s new Renewable Electricity Price Guarantee (REPG). Marketed as a “significant milestone” on the path to net-zero, the framework sets out how future auctions will support renewable generators, drive down bills and help deliver the legal target of 80 per cent renewable electricity consumption by 2030.
The announcement matters to households facing some of the UK’s highest electricity costs and to developers deciding where to locate the next wave of on-shore wind, solar and storage projects. A well-designed support scheme could unlock hundreds of millions of pounds of private investment and accelerate the region’s transition away from volatile fossil-fuel imports.
What the REPG will do
- Competitive auctions: The Department for the Economy (DfE) plans to hold the first auction “in early 2027”. Generators that bid successfully will receive a guaranteed strike price for the electricity they export, loosely modelled on Great Britain’s Contracts for Difference (CfD) and the Republic of Ireland’s Renewable Electricity Support Scheme (RESS).
- Community bill discounts: Households living near REPG-supported projects are to receive a yet-to-be-defined deduction on their electricity bills. Minister Archibald said this approach “will ensure that local communities benefit from the transition to net zero.”
- Legal and governance framework: The Final Scheme Design outlines the legislation, oversight bodies and settlement processes required to administer payments and recover costs in the all-island Single Electricity Market.
- Funding mechanism: Although the document references a “core mechanism for funding the scheme”, precise details—such as levy structure, cost caps and consumer protection measures—will be consulted on later this year.
- Eligibility and allocation: Basic criteria have been published, with fuller terms and conditions to follow in a statutory consultation before contracts are finalised.
Launching the scheme, the Minister argued that the REPG would “boost renewable generation and deliver lower electricity costs to households than they are paying today.”
Timeline and next steps
DfE intends to publish draft Terms and Conditions for public consultation “later this year”, giving industry, consumers and community groups a chance to comment on contract length, sustainability criteria, penalty clauses and more. Subject to legislation passing Stormont, preparatory work will continue through 2026, with the inaugural auction pencilled in for the first quarter of 2027.
The Department notes that the design “has been tailored to fit the unique characteristics of the all-island market”, which already trades power freely between Northern Ireland and the Republic. Officials have drawn on feedback to the Design Considerations for a Renewable Electricity Support Scheme consultation response issued in April 2024 and on the wider Energy Strategy Action Plan 2025.
What remains unsaid
- Size of community discounts: The announcement does not indicate how large the local bill rebates will be, who will qualify or how payments will be administered.
- Total budget exposure: There is no headline figure for the scheme’s cost ceiling, nor a clear explanation of how liabilities will be shared between Northern Ireland consumers and the broader UK Treasury if wholesale prices fall below strike prices for extended periods.
- Grid infrastructure: Accelerating renewables to 80 per cent within five years will require major upgrades to transmission and distribution networks. The press release is silent on whether the REPG will be accompanied by a parallel plan to fund grid reinforcement and reduce queue times for connection agreements.
- Planning reform: Northern Ireland’s on-shore wind planning regime is widely regarded as slower than those in Great Britain or the Republic of Ireland. The Final Scheme Design does not mention any fast-track measures to align consenting timescales with the 2027 auction window.
Broader context and policy gaps
Power prices in Northern Ireland sat around 35 pence per kWh in early 2025—up to 20 per cent higher than the UK average, according to the Consumer Council. While the REPG is framed as a cost-cutting tool, downward pressure will only materialise if auctions are competitive and if grid constraints do not curtail output.
Elsewhere in the UK, the latest CfD auction cleared at record-high strike prices due to inflation and supply-chain stress, prompting debate over whether subsidy schemes are still the cheapest route to decarbonisation. The Final Scheme Design does not reference these trends, nor does it discuss alternative options such as capped fixed-price Power Purchase Agreements or targeted support for battery storage.
Finally, energy poverty remains acute: one in three Northern Irish households is currently classed as fuel-poor (Department for Communities, 2024). Yet the REPG’s consumer-facing element is limited to geographically targeted discounts. Wider affordability measures—such as social tariffs or energy-efficiency grants—fall outside the scheme’s scope and are not addressed in the announcement.
Questions to consider
- What level of strike price will the Department set as a reserve to ensure auctions remain competitive yet attractive to investors?
- How large—and how long-lasting—will the promised community bill rebates be, and how will eligibility be verified?
- Will additional funding be made available to upgrade grid infrastructure so that new projects can connect before the 2030 deadline?
- How does the Department plan to coordinate the REPG with existing UK-wide schemes to avoid duplication or conflicting incentives?
- Given persistently high rates of fuel poverty, should the scheme be complemented by wider consumer-protection measures beyond the immediate vicinity of renewable projects?
Looking ahead
The REPG has the potential to reshape Northern Ireland’s power sector, attract fresh investment and cushion households against fossil-fuel price shocks. Whether it delivers on those promises will depend on the fine print still to come—particularly the funding mechanism, community-benefit rules and grid-capacity solutions.
Stakeholders may wish to prepare detailed submissions for the forthcoming Terms and Conditions consultation and to track legislation as it moves through Stormont. Transparency on costs, timelines and coordination with planning and network operators will be critical markers of progress over the next two years.
