The Dogger Bank offshore wind farm in the North Sea is facing significant construction delays that may push back its timeline for delivering low-cost electricity to consumers. Approved in 2019, the project was initially set to begin supplying power as early as 2023, but ongoing technical issues have hindered progress and raised questions about when the promised affordable energy will come online.
Located more than 80 miles off the coast of Yorkshire, Dogger Bank is poised to become the world’s largest offshore wind farm, with a planned capacity of 3.6 gigawatts generated by 277 turbines. Once complete, it is expected to provide enough clean electricity to power approximately six million homes. The project is jointly owned by SSE, a major FTSE 100 energy company, Norwegian state oil and gas producer Equinor, and Norwegian offshore wind firm Vargronn.
Dogger Bank’s development is divided into three phases: A, B, and C. Contracts for Dogger Bank A were awarded at a record-low strike price of £55.01 per megawatt-hour (MWh), considerably cheaper than existing UK offshore wind farms and roughly a third of current wholesale market rates, which have surged to around £162.50/MWh. Contracts for sections B and C were set at £57.92/MWh. At the time of approval, the government touted the project as a breakthrough in delivering renewable energy below market prices without additional consumer subsidies.
Although Dogger Bank A began generating electricity from its first turbine in 2023, the project encountered setbacks in 2024 after two turbine blades failed, leading to cascading delays. According to a recent government document, the wind farm continues to grapple with "unforeseen and significant technical issues" involving installation, remediation, and commissioning activities. These challenges, along with shortages of technical resources, have caused ongoing impacts on the construction schedule.
The fixed-price contract for Dogger Bank A requires part of the project to be operational by November 30, or the contract risks cancellation. It remains unclear whether the project will meet this deadline. Officials have indicated that cancelling the contract is unlikely given the urgency to secure affordable power amidst rising energy costs. Electricity generated during the commissioning phase is currently being sold at prevailing market prices, which remain high.
A spokesperson for Dogger Bank Wind Farm confirmed that while some construction delays have occurred, the project is maintaining momentum. They noted expectations that the majority of Dogger Bank A’s capacity will be available for generation by the end of 2026, with final commissioning continuing into 2027. Upon completion, the wind farm is expected to provide Britain with a significant source of secure, low-cost renewable energy on an unprecedented scale.
