RWE and KKR Reach Financial Close on £12bn UK Offshore Wind Mega-Deal
German utility RWE and US investment firm KKR said on November 11 that they have reached financial close on a £12 billion ($16 billion) investment to build two offshore wind farms in the UK North Sea, a deal the British government is calling the largest renewable-energy investment in the country’s history, OilPrice.com reported, citing RWE and UK government statements.
The financing covers Vanguard West and Vanguard East, two wind farms with a combined capacity of about 2.8 gigawatts (GW) that RWE says could power roughly three million UK homes once both are fully commissioned in 2030. For a sense of scale, the projects sit alongside Dogger Bank, the North Sea’s largest single wind farm, in a UK offshore pipeline that developers including Ørsted have helped build into the world’s second-largest after China’s.
From auction win to financial close
The RWE-KKR tie-up dates back to January, when RWE secured Contracts for Difference (CfDs) for 6.9 GW of offshore wind capacity in the UK’s seventh renewables auction round (AR7) and simultaneously agreed to bring KKR in as a 50% partner on the Vanguard projects — then known by their fuller name, Norfolk Vanguard East and West. At the time, RWE put the combined development and construction cost at more than $15 billion and said financial close, the point at which the funding needed to build a project is formally locked in, was expected by summer 2026.
Ten months on, financial close has arrived later than that original guidance but with a higher headline figure: the £12 billion ($16 billion) total now cited includes not just the turbines and foundations but the transmission infrastructure needed to bring the power ashore. Commercial terms of KKR’s stake were not disclosed in this week’s announcement; people familiar with the January deal had previously put the implied value of KKR’s 50% share at around $1.8 billion, a figure OilPrice.com’s report did not revisit.
Why private capital is still betting on UK offshore wind
The projects were originally developed by Sweden’s Vattenfall before passing to RWE. Infrastructure investors’ continued appetite for UK offshore wind is notable at a time when cost inflation has cooled enthusiasm in some other markets: the CfDs RWE won in the AR7 auction guarantee a fixed power price, which removes much of the revenue uncertainty that has made some wind projects elsewhere harder to finance, making them more predictable for institutional investors such as KKR.
Where it fits in the UK’s build-out
The UK currently has more than 16 GW of offshore wind in operation, against a government goal of over 43 GW by 2030, according to RenewableUK figures cited in the report. Offshore wind generated a record 52 terawatt-hours of power in 2025 — 17.9% of UK electricity generation, up from 48.8 TWh (17%) in 2024, per the government’s own Energy Trends data. Hitting the 2030 target will require a wave of projects reaching financial close in quick succession; the UK has also recently cleared the way for export cables linking projects such as Berwick Bank to the mainland grid, part of the same build-out logic underpinning Vanguard West and East.
Political backdrop
UK Prime Minister Andy Burnham called the investment “a vote of confidence for building in Britain,” according to a government statement cited by OilPrice.com. Government officials said the project is expected to support more than 2,400 jobs during construction and operation.
