The United Kingdom has just been at the center of a historic offshore wind energy auction which reinforces its leadership in this sector within Europe and sets a benchmark for other countries with renewable energy ambitions, such as offshore wind power in SpainThe seventh round of Contracts for Difference (AR7) has allowed the awarding of more than 8 gigawatts (GW) of new offshore capacity, with prices that, despite being higher than in previous auctions, are still clearly lower than the cost of new gas-fired power plants.
This move has implications not only for the The UK's electricity mix and its energy securityBut it is also reigniting the debate on the Iberian Peninsula about how and when offshore wind, especially floating wind, will take off. Many in the sector are closely watching the British experience to gauge which parts of that model are replicable within the regulatory and pricing context of the Spanish electricity market.
A record-breaking auction: 8,4 GW of new offshore wind power
The AR7 round has concluded with award of 8,4 GW of offshore wind capacityThis is enough to power approximately 12 million British homes when all projects are operational. The bulk of this capacity comes from fixed-foundation offshore wind, while floating technology adds a still modest but strategic portion to the overall package.
According to official data, the auction has allowed the allocation 6,86 GW of fixed wind farms in England and Wales y 1,38 GW in Scotland, which consolidates the North Sea and the Celtic Sea as major hubs for European renewable energy generation. Meanwhile, British floating wind power is advancing with 192,5 additional MW, pointing the way towards the use of deeper and more complex waters.
The British government estimates that this auction will unlock around £22.000 billion in private investment and will support nearly 7.000 skilled jobs across the country, from the Scottish Highlands to Wales and the east coast of England. It's not just about electricity capacity; it's also a clear commitment to the industry and regional development associated with the major offshore wind manufacturing and logistics hubs.
Overall, the London Administration presents this result as a decisive step towards its objective of clean electricity by 2030Following a previous round in which no projects were awarded and an AR6 auction that already marked the beginning of the recovery, AR7, with its volume and prices, is poised to consolidate this trend after a period of uncertainty in international markets.
Prices, contracts and technological competition
One of the most relevant pieces of information from the auction is the agreed price for fixed offshore wind. At 2024 values, the The average exercise price has stood at 90,91 pounds per megawatt hour, which is equivalent to about 65,25 pounds/MWh in 2012 terms and is about 40% less than the estimated cost of building and operating a new gas plant, which is 147 pounds/MWh.
Breaking it down by territory, the official figures place the Average price of £91,20/MWh for England and Wales y £89,50/MWh for ScotlandThis reflects slight regional differences, but confirms the clear competitiveness of conventional offshore wind compared to fossil fuel technologies. Although these figures are approximately 11% higher than those of the previous auction, the government insists they continue to offer good value for money for consumers.
In the case of the floating offshore wind powerThe exercise price is around 216 pounds/MWhThis level highlights its nascent nature and the higher costs associated with the design of platforms, anchors, and operations in deep water. Translated to constant 2012 prices, this equates to approximately £155,23/MWh, compared to £65,45/MWh in England and Wales and £64,23/MWh in Scotland for fixed wind farms.
All these projects fall under the scheme of Contracts for Difference (CfD)This mechanism guarantees a stable price for developers in the long term—in this round, for a period of 20 years. When the wholesale price falls below the agreed value, the system compensates for the difference; if the price rises above it, the generators return the surplus. This mechanism, widely observed in Europe, reduces volatility for investors and consumers and has been key to sustaining the massive deployment of renewables in the United Kingdom.
Wind megaprojects: Dogger Bank South, Norfolk Vanguard, Berwick Bank and Awel y Môr
The map of projects awarded in AR7 confirms the British ambition to become European large-scale offshore wind platformAmong the most outstanding parks are complexes that are already among the largest in the world, both for their power and their strategic importance.
In the North Sea, off the coast of Yorkshire, the project stands out Dogger Bank South, divided into two large units: Dogger Bank South East y Dogger Bank South West, with 1.500 MW each. Together they total 3.000 MW of fixed offshore windconsolidating this area as one of the major global wind energy hubs.
The complex is located in the east of England, in the East Anglia region. Norfolk Vanguard, structured in two main blocks: Norfolk Vanguard East (units A, B and C), with 1.545 MW, and Norfolk Vanguard West (also with three units), which contributes another 1.545 MW. In total, this development adds more than 3.090 MW capacity, becoming one of the great pillars of the expansion of English offshore wind power.
Scotland, for its part, contributes the project Berwick BankThe 1.380 MW wind farm, located in the North Sea off the east coast of Scotland, is set to become one of the world's largest offshore wind developments. It completes a complex whose final capacity is projected to reach approximately 4 GW when all phases are operational.
In Wales, the park Awel and Môr (Phase A) marks the return of new contracts After more than a decade without any new projects in the region, this project, with 775 MW of fixed offshore wind capacity, reinforces the role of the Irish Sea and the Welsh coast within the British wind energy ecosystem.
British floating wind power: Erebus and Pentland as technological vanguard
Although the volume awarded continues to be dominated by the fixed offshore wind turbineFloating technology is gaining prominence as a future strategy in deep waters. In the seventh round, two projects have become symbols of this new era: Erebus y Pentland Floating Offshore Wind Farm.
ErebusThe 100 MW wind farm is located in the Celtic Sea off the coast of Wales and represents one of the first significant-scale floating wind farm developments in the UK. Developed by Blue Gem Wind, this park is considered an intermediate step between purely experimental installations and the large commercial complexes that could arrive in the next decade.
The project PentlandFor its part, it contributes 92,5 MW of floating wind power in northern Scotland. Located off the Scottish coast, it is backed by the public investment vehicle Great British Energy and the National Wealth Fund, who see the floating platform as a key element for deploying renewables in areas where fixed foundations are not viable due to depth or seabed conditions.
Although prices are still significantly higher than those for fixed wind power, both the government and industry agree that these projects are essential for mature the technology, optimize the supply chain, and reduce costs in the coming years. The accumulated experience will serve as a direct reference for other European countries with deep coastlines, like Spain and Portugalwhere floating wind power is emerging as the main way to harness the offshore wind resource.
RWE, SSE and other winners: industrial concentration and strategic alliances
In the distribution of contracts, the German RWE emerges as one of the big winners from the auction, reinforcing its position as a dominant player in European offshore wind. The company has secured coverage for approximately 6,9 GW, a figure that reflects both its financial strength and its long-term commitment to the British market.
Within this package, RWE leads or co-leads some of the key projects: the parks Dogger Bank South East y Dogger Bank South West, of 1,5 GW each, both in the North Sea; and the projects Norfolk Vanguard East y Norfolk Vanguard Westwith capacities of around 1,5 GW per block, also located in the eastern English zone. In total, these assets represent a significant portion of the newly awarded offshore capacity.
RWE's strategy is based on a network of alliances with major investors and industrial partnersIn the case of Norfolk Vanguard East and West, the company has reached an agreement with the global firm KKR, which will acquire 50% of both projects. The final investment decision and financial closing are expected in the summer of 2026, with a view to a phased start of operations between 2029 and 2030.
The parks of Dogger Bank South will be developed in consortium with Masdar, while the project Awel and MôrOff the coast of Wales, the project is being developed in partnership with Stadtwerke München and Siemens. Together, these developments could supply renewable electricity to more than six million British households, reinforcing RWE's role as one of the key players in the country's energy transition.
The German company not only contributes capital, but also Technical experience in development, construction and operation of marine parks, something especially valuable in large-scale projects where the management of technical, environmental, and logistical risks is crucial. This collaborative model, in which established operators partner with investment funds or local utilities, is emerging as an increasingly widespread practice in Europe.
Energy security, pressure on bills and political debate
The commitment to offshore wind power is framed within a context of extremely high volatility in international energy marketswith episodes of sharp increases in gas prices linked to geopolitical tensions, especially in the Middle East and on the border of Eastern Europe. According to statistics compiled by the British government, the fluctuations in these markets have contributed to half of the recessions recorded since the 1970s.
Given this scenario, the London government argues that accelerating investment in domestically produced clean energy This is a way to reduce exposure to these fluctuations and gain more control over electricity costs. In fact, the government has complemented the auctions with budgetary measures aimed at easing bills, including average reductions of around €150 per year per household starting in April.
The Secretary of Energy, Ed MilbandHe described the auction results as “a historic triumph” and emphasized that the country is “regaining control of its energy sovereignty.” According to his argument, renewable energy generated at home is the best option for permanently reducing bills and create quality jobs throughout the territory.
However, the auction has not been without political controversy. The Conservative opposition has criticized the fact that the new fixed-base offshore wind CfDs were closed at £90,91/MWh, approximately 11% higher than the previous round, arguing that this could “lock the country to high prices for decades.” The government counters that, even with this increase, the contracts are still much cheaper than new gas-fired plants and offer reasonable protection to consumers against future price escalations.
The industry, for its part, has received the auction as a clear boost to the offshore wind sector After a challenging period in which several European auctions were unsuccessful or saw low participation, organizations such as the Global Wind Energy Council believe that the British results "demonstrate that offshore wind is back in full force" and reinforce the UK's status as a priority destination for international renewable energy investment.
Connections with Spain and Europe: prices, floating costs and regulatory delays
The quantitative success of the British auction contrasts with the Regulatory gridlock facing offshore wind in Spainwhere the first major auction—particularly relevant for floating technology—remains pending despite repeated government announcements. This difference in pace has reignited the debate about the extent to which the UK model can serve as a reference for the Iberian Peninsula.
One of the points that generates the most controversy is the level of awarded prices in the AR7. In the British case, some of the floating and pre-commercial projects are priced at over €150-170/MWh when converted to euros, far removed from the context of the Spanish wholesale market. In Spain, the average pool price in 2025 was around € 65 / MWhsupported by a strong penetration of onshore and solar renewables, which makes it difficult to justify, at present, a massive incorporation of marine generation at such high prices in the peninsular system.
The Spanish Wind Energy Association (AEE) insists that this is incomparable situationsFactors such as distance from the coast, sea depth, facility design, park size, maturity of floating technology, and logistical costs vary considerably between the North Sea, the Scotia Sea, and the Spanish coast. Furthermore, many of the floating projects awarded in the UK have capacities in the 90-100 MW range and wind turbines of around 10 MW, placing them closer to pre-commercial installations than to truly large commercial wind farms.
Where replicating some aspects of the British model could make economic sense is in isolated electrical systems such as the Canary Islandswhere the current cost of conventional generation far exceeds that of the Iberian Peninsula. The AEE points out that, with a commercial floating installation of between 200 and 250 MW, the savings for the system could exceed 100 million euros annually, reaching up to 115 million if the value of carbon credits and other factors associated with decarbonization are taken into account.
At the European level, there are also precedents of high prices linked to very specific contexts, such as the case of a 17 MW pre-commercial floating wind farm in Japan, with a price close to €200/MWh in an area affected by typhoons and with small wind turbines. For the sector, these examples serve as a reminder that The cost of experimental facilities cannot be directly extrapolated what large retail parks should be worth in mature markets.
European industry and Spain's role in the value chain
Beyond price comparison, the British auction focuses on the European offshore wind supply chainwhere Spain already plays a significant role despite not yet having operational wind farms in its waters. The alliance between Navantia Seanergies and Windar Renovables is a good example of how the Spanish industrial sector has positioned itself in the manufacture of components for international projects.
At the Fene shipyard (A Coruña), both companies have recently completed the Jacket number 200 for offshore wind turbines, manufactured in SpainThis is a fixed foundation for the Dieppe le Tréport marine wind farm in France, developed by a consortium led by Ocean Winds. Since its first contracts more than a decade ago, the alliance has supplied structures for wind farms such as Wikinger (Germany), Moray East and East Anglia One (UK), Nissum Bredning (Denmark), and St. Brieuc (France).
These 200 jackets produced in Galicia are in addition to others 80 units built in the United Kingdom at the facilities acquired by Navantia UK in 2025, specifically in Methil (Scotland) and at the Harland & Wolff shipyard in Belfast. A large part of these structures have been allocated to British projects, such as Ormond, Beatrice, and East Anglia One itself, to the point that the total manufactured by the alliance represents approximately half of the jackets installed in Europe.
The Fene shipyard has thus established itself as a European center of reference in offshore wind energycombining jacket production with the manufacture of floats, monopiles, and, soon, offshore electrical substations. Although Spain has not yet deployed its own large-scale offshore wind farm, its companies are already integrated into the major British and Northern European projectssupplying critical components that sustain this boom.
Given this scenario, the Spanish Government has begun to support the preparation of key infrastructure such as portswith aid aimed at strengthening the logistics and industrialization associated with offshore wind. However, the sector insists that, without a a clear auction schedule and a stable regulatory frameworkIt will be difficult to consolidate a complete value chain in Spain that also includes the development of projects in national waters.
While London is moving forward with regular auctions and a scheme well-known to investors, in Madrid there is still a sense of... certain blockage in decision-makingDespite the fact that a public consultation has already been held and there are formal targets in the energy planning to 2030. For many stakeholders, the British experience demonstrates that projects drive technology, technology drives logistics, and in that mechanism, ports and industry need clear signals of future demand.
The UK's move, with an auction that combines high volume, long-term contracts and a mix of fixed and floating wind powerThis reinforces its position as a European leader in the energy transition and sends a clear message to its neighbors: whoever sets the pace for regulation and investment first will be the first to capitalize on the industry, jobs, and innovation associated with the sea. For Spain and other European countries, the challenge lies in finding a balance between consumer protection, the competitiveness of the electricity system, and the need to harness offshore wind resources, which, if well managed, can become a cornerstone of decarbonization in the coming decades.
