Ørsted abandons multibillion-pound Hornsea Four wind farm development citing rising costs

The 180-turbine wind farm had received a Government contract for difference award last year

Energy giant Ørsted has halted worked on the final wind farm of the mammoth Hornsea zone in the North Sea.

The Danish multinational has citied rising supply chain costs, higher interest rates and increased timeline risks surrounding the construction of the 2.4GW Hornsea Four wind farm. It deals a blow to clean energy ambitions in the º£½ÇÊÓÆµ following the project's approval in 2023, and to the wind farm's Grimsby service base.

Ørsted had planned a 180-turbine development to complete the Hornsea zone which includes Hornsea One and Two - already in operation - and Hornsea Three which is under construction. The development secured a contract for difference award in September last year.

In an update to investors, Ørsted said it had stopped spending on the project and terminated supply chain contracts. Costs of between 3.5bn-4.5bn Danish Krone (£399m-£513m) are now expected following the decision, including a write-down of assets and contract cancellation fees.

However, Ørsted says it will consider future development as it hangs on to seabed rights, a grid connection agreement and a Development Consent Order.

Rasmus Errboe, group president and CEO of Ørsted, said: "We remain fully committed to being an important partner to the º£½ÇÊÓÆµ Government to help them achieve their ambitious target for offshore wind build-out and appreciate the work they’ve done to deliver a clear framework to support offshore wind.

"However, our capital allocation is based on a strict and value-focused approach, and after careful consideration, we’ve decided to discontinue the development of the Hornsea 4 project in its current form, well ahead of the planned Final Investment Decision later this year.

“We’ve been maturing the project over the past nine months and have been working relentlessly with stakeholders and suppliers to manage the different project risks for a project of this scale.

"Throughout the development phase we’ve been very diligent in our approach to capital commitment to our suppliers, and our committed capital is well below our threshold. The adverse macroeconomic developments, continued supply chain challenges, and increased execution, market and operational risks have eroded the value creation.

"I’d like to emphasise that Ørsted continues to firmly believe in the long-term fundamentals of and value perspectives for offshore wind in the º£½ÇÊÓÆµ. We’ll keep the project rights for the Hornsea 4 project in our development portfolio, and we’ll seek to develop the project later in a way that is more value-creating for us and our shareholders."
