Offshore wind turbines on the horizon over the sea off the Norfolk coast

RWE and KKR Seal £12 Billion Offshore Wind Deal to Power 3 Million UK Homes

November 12, 2026 Faizan Altaf

Britain has just recorded one of the biggest clean-energy investments in its history. German energy company RWE and American investment firm KKR have agreed to spend around £12 billion — about $16 billion — building two huge offshore wind farms off the Norfolk coast in the North Sea.

The two projects, called Vanguard West and Vanguard East, will have a combined capacity of 2.8 gigawatts. That is enough electricity to power around three million UK homes. Construction at sea starts in early 2027, and both wind farms are expected to be fully running by 2030.

The deal was announced on Wednesday, 11 November 2026, just as world leaders gathered in Antalya, Turkiye, for the COP31 climate summit. The British government welcomed the investment and said it would support more than 2,400 jobs during construction and operation.

What Was Announced

RWE and KKR said they had reached “financial close” on both wind farms. In simple terms, that means all the money is now in place and the projects can go ahead.

The two companies have also completed a deal first announced in January 2026: KKR has bought a 50% stake in each project, creating an equal partnership with RWE. RWE will lead the building and delivery of the wind farms.

Each wind farm will have an installed capacity of 1.4 gigawatts, giving a combined total of 2.8 gigawatts. The turbines will stand between 50 and 80 kilometres off the Norfolk coast in East Anglia, in the southern North Sea.

The £12 billion covers the cost of building the wind farms and the cables and substations needed to carry the electricity ashore.

The Two Wind Farms in Numbers

Here are the key facts about the Vanguard West and Vanguard East projects:

Total investment: Around £12 billion (about $16 billion)
Combined capacity: 2.8 gigawatts (1.4 gigawatts each)
Location: 50 to 80 kilometres off the Norfolk coast, North Sea
Homes powered: Around 3 million UK homes
Jobs: More than 2,400 during construction and operation
Ownership: 50:50 joint venture between RWE and KKR
Construction starts: Early 2027
Fully running: 2030

What Is ‘Financial Close’ — and Why It Matters

“Financial close” is the moment when a big project stops being a plan on paper and becomes something that will actually be built. It means the developers have signed binding agreements with all the banks and investors providing the money.

For Vanguard West and Vanguard East, the financing package is the largest ever put together for a UK offshore wind project. A group of 35 international banks is providing £11.1 billion in cash facilities and a further £1.7 billion in ancillary facilities — a total of £12.8 billion in bank financing.

Britain’s publicly owned National Wealth Fund is also taking part, committing £1 billion. This is the fund’s first time financing UK offshore wind projects.

The financing is “non-recourse”, which means the banks will be repaid from the money the wind farms earn by selling electricity, rather than from RWE’s or KKR’s own balance sheets. That is a sign of confidence: lenders are willing to bet on the projects standing on their own.

Who Is Paying for the Power?

Big wind farms need buyers for their electricity, and the Vanguard projects already have that sorted. In January 2026, both projects won 20-year Contracts for Difference — known as CfDs — in the UK government’s Allocation Round 7 auction.

A Contract for Difference is a deal between the government and a power producer. It sets a fixed price for the electricity the project will produce. If the market price falls below that fixed price, the government tops it up. If the market price rises above it, the producer pays the difference back. The idea is to give investors certainty, so they are willing to fund expensive projects like offshore wind farms.

For Vanguard West and Vanguard East, the agreed price is £91.20 per megawatt-hour, in 2024 prices, adjusted for inflation over the 20-year life of the contract.

What Happens Next

Work on land is already well advanced. Cables are being laid and substations built to connect the wind farms to the national grid.

The next big step is offshore construction, which is due to begin in early 2027. The first turbine foundations for Vanguard West are planned for the first half of 2027, followed by Vanguard East. Full commissioning of both projects is expected in 2030.

RWE’s chief executive, Markus Krebber, said preparatory works were “well advanced”, putting the company “in a strong position to begin offshore construction in early 2027”.

Why This Deal Matters for the UK

The UK is already one of the world leaders in offshore wind, and the government wants clean power to supply the country’s electricity by 2030. Projects like Vanguard are essential to that plan, because wind power at this scale can replace electricity from gas-fired power stations. Britain already has one of the largest offshore wind fleets in the world, built up over more than two decades, and the government sees wind as the backbone of its clean-power plans.

The deal also matters because of its size. The government described it as the biggest investment of its kind in UK history. At a time when energy costs and energy security are high on the political agenda, a project that produces home-grown electricity — and does not depend on imported gas — is attractive to ministers.

The timing is also significant. The announcement came on the same week as COP31, the United Nations climate summit in Antalya, Turkiye, where Prime Minister Andy Burnham was due to attend. The government used the deal to show that Britain is still attracting major clean-energy investment, even as it defends its approval of a controversial new North Sea gas field.

There is also a jobs story. The government said the investment would support more than 2,400 jobs during construction and operation, many of them in East Anglia and in the wider UK supply chain.

The Bigger Picture: Offshore Wind After a Difficult Few Years

Offshore wind has had a bumpy ride in recent years. Building costs rose sharply, interest rates climbed, and some developers walked away from projects or asked governments for better prices. The January 2026 auction in which Vanguard won its contracts secured a record amount of offshore wind capacity, showing that the government’s pricing was finally drawing developers back.

The Vanguard deal suggests the industry is finding its footing again. The fact that 35 banks were willing to lend, and that a major private equity firm like KKR put up half the equity, shows that investors believe offshore wind can make money at today’s prices.

RWE itself reported strong results on the same day as the announcement. The company said its adjusted earnings before interest, tax, depreciation and amortisation rose 35% to €4.6 billion in the first nine months of 2026, compared with €3.4 billion a year earlier.

For the UK, the challenge now is delivery. The Vanguard wind farms will not produce a single unit of electricity until the end of the decade, and offshore construction is complex, weather-dependent work. But with the money secured and the contracts signed, the projects have cleared their biggest hurdle.
