Ørsted - Walney Extension

What Ørsted - Walney Extension does

Ørsted - Walney Extension is a 659 MW operational offshore wind farm located approximately 19 km west of Barrow-in-Furness in the Irish Sea, UK. Inaugurated on 6 September 2018 after being constructed on time and on budget, it held the title of the world's largest offshore wind farm until Hornsea 1 surpassed it in 2020. The asset spans 145 km² and comprises 87 turbines deployed across two phases: 40 MHI Vestas 8 MW units with blades from the Isle of Wight and 47 Siemens Gamesa 7 MW units with blades from Siemens Gamesa's Green Port Hull factory and towers from CS Wind's Campbeltown facility.

Ownership is shared between Ørsted A/S (50%), the publicly listed Danish energy company (Nasdaq Copenhagen: Orsted), and a partnership of AIP Management (Danish infrastructure investor) and PFA (Denmark's largest commercial pension company). The project sells electricity to the UK national grid under regulated market arrangements and offers a separate Corporate PPA programme to business customers. Net output is sufficient to power approximately 600,000 UK homes and brings Ørsted's total capacity operating out of Barrow to 1.5 GW.

Operations and maintenance are delivered from Ørsted's Barrow-in-Furness base, supporting more than 250 direct regional jobs and engaging over 50 local suppliers during construction. The Walney Extension Community Fund, administered by GrantScape, provides roughly £600,000 per year for community projects in Cumbria and Lancashire over the asset's 25-year operating life, with over £3 million awarded to 184 projects since 2016.

Core offering

Walney Extension is a 659 MW offshore wind farm located approximately 19 km west of Barrow-in-Furness in the Irish Sea, comprising 87 turbines (40 MHI Vestas 8 MW and 47 Siemens Gamesa 7 MW) that generate clean electricity sufficient to power nearly 600,000 UK homes. The project is owned 50% by Ørsted with partners AIP Management and PFA holding the remaining stake, and electricity is sold to the UK grid and to corporate customers via long-term Power Purchase Agreements (PPAs). The wind farm is operated and maintained from Ørsted's Barrow-in-Furness base, covering 145 km² of sea area.

Product overview

Walney Extension is a single offshore wind farm project, not a platform product. It is operated and maintained from Ørsted's base in Barrow-in-Furness, covering an area of 145km² (equal to approximately 20,000 football pitches or 10x Lake Windermere). The project was owned by Ørsted (50%) and partners AIP Management and PFA, and brought Ørsted's total capacity operating out of Barrow to 1.5 GW. The wind farm supports over 250 direct jobs in the region and includes the Walney Extension Community Fund providing approximately £600,000 annually for community projects over the 25-year expected lifetime.

Direct peers

• Hornsea 2: Ørsted's 1.32GW Hornsea 2 in the North Sea is one of the world's largest operating offshore wind farms. Direct peer sharing the same Ørsted operating platform, UK grid offtake, and PPA structures as Walney Extension.
• Hornsea 1: Ørsted's Hornsea 1 is a 1.218GW offshore wind farm in the North Sea that surpassed Walney Extension as the world's largest in 2020. Direct peer — same developer, same revenue model (UK grid PPAs), same customer base and operational structure.
• Triton Knoll: RWE and J-Power's 857MW Triton Knoll offshore wind farm in the North Sea is a direct comparable to Walney Extension in scale, technology vintage, and UK PPA/grid offtake.
• Moray East: Ocean Winds' (EDP/Engie JV) 950MW Moray East offshore wind farm in Scotland is a direct UK peer of similar vintage and scale, using comparable MHI Vestas 9.5MW turbines and selling into the UK grid/PPA market.
• Dogger Bank A/B/C: SSE, Equinor and Vargrønn's Dogger Bank (3.6GW total) is the world's largest offshore wind farm under construction. Direct peer — same UK North Sea market, PPA offtake, and operational model; defines the next-generation benchmark Walney is being compared against.
• Beatrice Offshore Wind Farm: SSE Renewables and Copenhagen Infrastructure Partners' 588MW Beatrice offshore wind farm in the Moray Firth, Scotland. Direct peer — comparable fixed-bottom UK offshore wind generation asset with similar PPAs and grid supply.
• East Anglia ONE: ScottishPower Renewables' (Iberdrola) 714MW East Anglia ONE is a UK North Sea offshore wind farm. Direct peer — same fixed-bottom offshore wind generation model, similar scale, and same UK grid/PPA offtake structure.

Broad incumbents

• Equinor Renewables UK: Equinor operates Hywind Scotland (floating) and Dudgeon/Sheringham Shoal (fixed-bottom) offshore wind in the UK. Broad incumbent with comparable UK offshore wind generation and PPA business, plus broader oil-and-gas heritage.
• Vattenfall (UK offshore wind portfolio): Vattenfall operates multiple UK offshore wind farms (e.g., Norfolk Vanguard, Aberdeen Offshore Wind Farm). Broad incumbent with deep offshore wind expertise and overlapping UK PPA customer base, though a broader European utility portfolio.

Others

• Siemens Gamesa Renewable Energy: Siemens Gamesa supplied 47 of Walney's 87 turbines and is the dominant global offshore wind turbine OEM. It is an enabling technology peer/ecosystem participant rather than a direct competitor, but its technology roadmap directly determines Walney's repowering economics and long-term competitiveness.
