Question to the Department for Energy Security & Net Zero:

To ask the Secretary of State for Energy Security and Net Zero, if he will make an estimate of the cost of building (a) the Western link and (b) all current and future stages of the Eastern Link if that route was primarily overland via pylons instead of offshore cabling.

Ofgem reviews proposed project costs and ensures that network companies spend efficiently. Electricity network reinforcements are only approved where they are in the interests of consumers and help reduce system costs.

Ofgem identified a net lifetime benefit for Western Link, due to lower project and constraint costs compared to alternatives. [1] The system operator set out the project need case in 2007.

Ofgem’s analysis [2]of Eastern Green Link 1 and 2, noted that onshore reinforcements would not achieve required delivery dates resulting in increased constraint costs.
