The UK government has launched its fourth and so far largest cycle of contracts for difference (CfD) for renewables, offering £۲۸۵ million* (€۳۳۵ million) per year to secure 12 GW of green capacity across the UK. Agent-based modelling, auction theory, contracts for difference, EL 33, EL33, electricity market reform, offshore wind, real option analysis, renewable energy auctions Today`s auction is likely to challenge biases about renewables. For example, Professor Dieter Helm, who is leading a government review of energy costs, said offshore wind farms will “never” be economical. A new report from research firm Cornwall Insight explores the role of Contract for Difference (CfD) generators in expanding the UK`s offshore wind and renewable energy portfolios. In response to today`s cfd announcement, the Chair of the Environmental Audit Committee, the Right Honourable Philip Dunne MP, said: “The UK has the geographical chance to be a renewable energy power plant. I am pleased that the potential of floating offshore wind and tidal current has finally been recognised as a contribution to our future low-carbon energy mix. This support for renewable energy will help Net Zero Britain, give investors welcome demand signals and give the industry the confidence it needs to secure capacity for the future. “In addition, Cornwall Insight has updated its views on capture prices for wind technologies to reflect the increasingly cannibalized nature of wind stocks in the electricity market. These are now well below the typical base price view, which means that wind turbines get a discount compared to typical market prices.
For nuclear power, the strike price of Hinkley C is displayed. Note that this is a 35-year contract that spreads the cost over several years, depressing the price compared to 15-year renewable energy contracts. “Already in 2021, we saw that the standard deviation of overnight electricity prices – a good approximation of volatility – increased significantly compared to previous years. Although it is also due to weather and failure factors of larger power plants, the low wind production in Q1 2021 is also a determining factor. The government has also published the auction criteria for the fourth CfD allocation. The auction consists of three different pots. The first pot is dedicated to established onshore technologies, including onshore wind, solar and hydropower. The government is providing a budget of £۱۰ million for a total capacity limited to 5 GW. This pot is technology neutral, which means that different technologies compete for price.
To ensure that the different technologies in this pot have a fair chance of being auctioned, the maximum capacity of the successful bids for onshore wind and solar is limited to 3.5 GW. This is the first time since 2015 that the UK government has provided public support for onshore wind energy. For offshore wind, the prices shown reflect the orders already awarded for each delivery year, drawing a straight line between years. For onshore wind, contract prices are displayed for 2017, LCOE forecasts for 2018 and 2020, and then an estimate for 2022 by the consulting firm Baringa Partners. (Note that wind farms in the UK almost always produce electricity, while their production varies. For example, in November 2016, offshore wind generated nearly 100% of the hours. BEIS expects new offshore wind farms to have a utilization factor of nearly 50%.) GlossaryCharger Factor: A measure of the average power of a power plant in relation to its installed capacity. It depends on technical and economic factors. For individual gas, coal or nuclear power plants, the utilization factor can theoretically be more than 90%. However, the averages of the British fleet are much lower. The range of fleet-wide average load factors over the period 2010-2014 was 28-62% for gas, 40-57% for coal and 65-74% for nuclear. The price range for the UK`s renewable fleets was 10-11% for solar, 22-28% for onshore wind and 30-38% for offshore wind.
New wind farms tend to have larger turbines, especially offshore, and they are expected to achieve utilization factors of up to 48%. CloseLoad factor: A measure of the average power of a power plant in relation to its installed capacity. It depends on technical and economic factors. For individual gas, coal or nuclear power plants, capacity utilization is. These frequently asked questions and answers (“FAQs”) are prepared by Low Carbon Contracts Company Ltd (“LCCC”) in response to stakeholders` questions regarding the content of the Contract for Difference (“CFD”), which includes the CFD Agreement and the Standard CFD Terms (“Terms”) as published by the Ministry of Business. Energy and Industrial Strategy on August 29, 2014. The FAQs also apply to investment contracts (“ICs”), but users of this website are advised to carefully review the relevant clauses of their CI, as there are differences between the CFD and the CI. The additional offshore wind capacity resulting from the financing alone could generate enough electricity to power about 8 million homes, the government said. The CfD model is credited with promoting the deployment of offshore wind and lowering prices.
The price per unit of offshore wind fell by about 65% between the first allocation cycle in 2015 and the third in 2019, according to the UK`s Department of Economic Affairs, Energy and Industrial Strategy (BEIS). At the last auction, offshore wind costs fell by a third to collapse by around £۴۰ million, which is well below the price of electricity on the UK`s wholesale energy market, meaning households are unlikely to face higher charges for their energy bills. The UK government has announced the auction criteria for the upcoming fourth round of cfD auctions. The auction will be the world`s largest renewable energy auction and could add more than 12 GW of new renewable capacity. It will consolidate the UK`s position as the world`s leading supplier of offshore wind energy. In particular, it will also allow the return of British onshore wind and the launch of the floating wind. The number of technologies supported under the programme will also be increased in the final round, with offshore wind, onshore wind, solar, tidal and floating offshore wind projects all eligible. This is the first time floating offshore facilities have been eligible for the program, and the first time since 2015 that onshore wind and solar have been included. Since their last competition, onshore solar and wind projects have become profitable without subsidies under good conditions.
The table below shows the CfD awards for wind and solar (blue and yellow lines) compared to the new Hinkley C nuclear power plant (purple line), which has a 35-year CfD for £۹۲٫۵۰/MWh. red). Two offshore wind projects have won contracts with record levels of £۵۷٫۵۰ per megawatt hour (MWh). This makes it one of the cheapest new sources of electricity generation in the UK, joining onshore wind and solar, with all three being cheaper than new gas, according to government forecasts. “While this investment is extremely welcome, the government also needs to assess the infrastructure that supports renewable energy. Investment cannot accomplish much if infrastructure cannot support the projects to be carried out. Our committee, as part of its work on technological innovations, has highlighted the need to examine the grid connection of offshore wind farm expansion and the need to adequately invest in deep-water port capacity. “Our forecasts also show that these factors will increase in the future as offshore wind development continues to develop under the program.
In the meantime, the system will also be more sensitive to periods of high demand and persistent weather conditions, which can have significant price spikes, as seen in January of this year. .
