Wind Power: Radar

Question: To ask the Secretary of State for Energy Security and Net Zero, with reference to his Department’s press release entitled New radar systems to unlock offshore wind, published on 20th March 2026, what estimate he has made of the amount of offshore wind capacity that has been delayed or constrained due to radar-related issues.

Answer: As part of a mission led Government, the Department for Energy Security and Net Zero and the Ministry of Defence and have worked together to assess the impact of offshore wind on the UK’s radar systems and the potential for delays to offshore wind deployment. This collaborative effort informed the procurement of the new specially designed air defence radar systems, which will facilitate the co-existence of up to 10 GW of offshore wind capacity, enabling the Government to deliver its clean power mission whilst protecting national security.
