Question to the Department for Energy Security & Net Zero:

To ask the Secretary of State for Energy Security and Net Zero, pursuant to the Answer of 8 October to Question 5072 on National Grid: Costs, what estimate he has made of the potential impact on consumer energy bills of the lifetime costs of delivering the coordinated offshore design set out in the Offshore Coordination Support Scheme for East Anglia.

As part of the feasibility work for the coordination proposal explored through the Offshore Coordination Support Scheme, independent analysis by Arup and the Electricity System Operator (now the National Energy System Operator) identified an increase in development costs by up to £890 million, and additional constraint costs of greater than £1.5 billion over the project lifetime. While these costs would be expected to be recovered from consumer electricity bills, the interactions with other bill components mean there are uncertainties preventing a precise estimate of the impact.
