The wind farm, which is located about 19km from the coast and spread across an area of 145km², has a total of 87, out of which 40 were supplied by MHI Vestas. The remaining 47 were supplied by Siemens Gamesa.

Ørsted’s Walney Extension programme director Andrew Cotterell said: “We’re delighted to announce that all 87 turbines have been installed.

“We are now focussed on completing construction and looking forward to seeing the world’s largest wind farm brought safely into commercial operation later this year.”

The Walney Extension wind farm is expected to start its operations in the second half of this year. When fully operational, the wind farm is expected to generate enough energy which can be supplied to more than a million households in the UK.

Cotterell added: “Walney Extension is a prime example of the UK leading the way for offshore wind globally – demonstrating the commercial viability of the latest turbine technology from MHI Vestas and Siemens Gamesa, as well as the strength of the rapidly growing UK supply chain with blades manufactured on the Isle of Wight and in Hull.”

Danish clean energy giant Ørsted owns 50% stake in the wind farm, while the remaining is held by two Denmark-based pension funds PFA and PKA with 25% each.

In November last year, Ørsted, formerly Dong Energy had agreed to sell 50% of stake in Walney Extension offshore wind farm to PKA and PFA.

The sale price of £2bn includes the 50% ownership share along with a commitment to pay funds for 50% of EPC contract for the whole wind farm.

Legal & General had provided £300m in long-term debt to help Danish pension funds, PKA and PFA consortium acquire the stake in the wind farm.
