My Lords, these regulations were laid before the House on 28 October. They form an important part of the Government’s commitment to accelerate the deployment of the low-carbon electricity technologies that are critical to achieving the Government’s clean energy mission.
The contracts for difference scheme is the Government’s main mechanism for supporting new low-carbon electricity generating projects in Great Britain. Contracts for difference are awarded through annual, competitive auctions where the lowest-priced bids are successful. The sixth allocation round, which ran earlier this year, was the largest round ever and more than double last year’s round held by the previous Government. It awarded contracts to 128 clean energy projects across Great Britain, capturing 9.6 gigawatts of renewable capacity and generating enough electricity to power the equivalent of 11 million homes.
We must, though, ensure its continued success and evolve the contracts for difference scheme to drive progress towards 2030. So, building on auction round 6, we want to update the scheme through this instrument to continue our march towards a low-carbon power system. We propose, first, to extend the option of phased contracts for difference to floating offshore wind projects and, secondly, to enable the eligibility of repowered onshore wind projects to apply for a contract for difference.
On the first point, the Government have committed to radically increasing the UK’s offshore wind capacity, including floating offshore wind. As an emerging technology with less than 250 megawatts of capacity deployed worldwide, the floating offshore wind construction process is yet to be industrialised. Floating wind projects are likely to have a slower buildout rate than established fixed-bottom offshore wind, for reasons including limitations on suitable port capacity and increased sensitivity to adverse weather.
Phasing in the contract for difference allows projects to be built in multiple stages. It was designed to provide support for early fixed-base offshore wind projects by mitigating the specific commercial risks inherent in offshore project construction. Extending this policy to floating offshore wind projects will allow for greater flexibility in the construction phase, allowing delivery to more realistic timelines and providing more certainty and confidence to the wider supply chain. This reduction in project risk will, in turn, increase investor confidence in the UK’s growing floating offshore wind sector.
On the second amendment—to enable repowering for onshore wind—our analysis suggests that approximately 1 gigawatt of onshore wind will come to the end of its operating life between 2027 and the end of 2030. Repowering can help ensure that renewable generation capacity is not lost from older projects. It also provides an opportunity to increase the renewable generating capacity of existing sites through improvements in technology and more efficient use of the site. Enabling access to the contract for difference for repowered onshore wind projects offers them revenue certainty, encouraging retention and expansion of existing capacity. This supports our ambition to achieve clean power by 2030 and make Great Britain a leading place for onshore wind investment.
