The UK government has announced details of the financial backing for the next Allocation Round (AR) in its flagship renewables auction
£205M (US$247M) has been pledged for AR5, the first of what is now an annual auction for renewable energy capacity in the flagship contracts for difference (CfD) scheme.
The £205M includes £170M for established technologies such as offshore wind and £10M that has been ring-fenced for tidal stream technologies. Offshore wind has been at the heart of the scheme and the UK now has the largest operational fleet in Europe and an ambition to deploy up to 50 GW by 2030, including up to 5 GW of floating offshore wind.
Minister of State for Energy Security and Net Zero Graham Stuart said, “The contracts for difference scheme is already delivering clean, homegrown energy as well as growing a green economy with green jobs.
“The announcement in the budget, the move to annual auctions and continued investment in renewable energy will limit the impact of events like Putin’s illegal war in Ukraine and drive our overriding priority for the UK to have among the cheapest wholesale electricity prices in Europe.
“I am excited to see the opportunities that will open for Britain’s world-class renewable industries as annual auctions kick off this year, enhancing the UK’s reputation as among the most attractive places to invest in for a secure, affordable and prosperous future.”
Responding to the announcement, RenewableUK warned that the plans set out by the Government for this year’s round of auctions “will not maximise investment in wind, solar and tidal projects.”
RenewableUK economics and markets manager Michael Chesser said, “Unfortunately, in the light of global inflationary pressures, the budget and parameters set for this year’s CfD auction are currently too low and too tight to unlock all the potential investment in wind, solar and tidal stream projects which the industry could deliver.
“Concerns about energy bills and energy security are at a record high, so the UK should be trying to maximise investment in low-cost clean energy, to provide relief for billpayers who’ve been hit hard by massive spikes in global gas prices over the past year.
“At a time when the US and EU are bending over backwards to offer incentives for developers to build new projects, the UK is sending the wrong investment signals.
“As a result, we risk losing vital opportunities to scale up our supply chains around the UK, denying communities the industrial-scale benefits which our sector offers. We are also jeopardising our global lead in cutting-edge clean energy technologies like floating wind and tidal stream.
“We are calling for the Government to revise the CfD budget so that we can stay on track to deliver on our renewable energy targets, as well as creating tens of thousands of high-quality green tech jobs and attracting billions in private investment in the years ahead.”
As announced in the Core Parameters publication in December 2022, CfD AR 5 will feature two auction pots with offshore wind now competing alongside other established technologies, enabling it to build on its great success and remain competitive with other renewable technologies.
Arranged across two ‘pots’, this year’s fifth AR includes an allocation of £170M to Pot 1 for established technologies – which for the first time includes offshore wind and remote island wind – and confirms an allocation of £35M for Pot 2 which covers emerging technologies such as geothermal and floating offshore wind, as well as a £10M ring-fenced budget available for tidal stream technologies. A two-pot structure will also support competition in AR5 to drive efficient and long-term support for low-carbon generation.
The CfD round is scheduled to open to applications on 30 March. Results of the AR5 auction are expected Q3 2023. After the closing date National Grid ESO will assess and value all qualifying applications and notify the Secretary of State, who may then consider whether to increase the budget for the allocation round.
Monetary support (pot budget) estimates in this notice, including the £205M total figure and split across the two pots, are presented in 2011/2012 prices in line with the Control for Low Carbon Levies. These figures are an estimate of annual support in the most expensive year in the first five (Pot 1) or four (Pot 2) years following deployment. Actual annual figures will vary over the lifetime of the contract depending on future wholesale electricity prices, and outcomes of the competitive auction process.
The budget is set by taking into account best knowledge, at that moment in time, about the anticipated firm project pipeline. The government has the opportunity to review the budget, after applications have been assessed by the CfD delivery partner (the EMR Delivery Body – National Grid ESO) and once the government has greater certainty about participation in AR5.
The government has also published other key documents for AR5 and a response to the consultation on AR5 contract changes. It noted that during periods of high wholesale electricity prices, CfD generators should ordinarily pay money back into the scheme but that, by delaying their start dates, some generators were making extra profit on the wholesale market. As a result, the government has also confirmed a technical change to the AR5 contract, confirming that flexibility to delay contract start dates should not be used by generators to benefit from higher prices on the wholesale market.
