Written question asked by John Lamont (Conservative) on Monday, 10 November 2025, in the House of Commons. It was due for an answer on Wednesday, 12 November 2025. It was answered by Michael Shanks (Labour) on Tuesday, 18 November 2025 on behalf of the Department for Energy Security and Net Zero.


Eskdalemuir Seismological Array

Question

To ask the Secretary of State for Energy Security and Net Zero, whether the Eskdalemuir Working Group will prioritise (a) the maintenance of national security and (b) international defence obligations when considering any new (i) regime and (ii) methodology for measuring seismic interference within the safety zone around the Eskdalemuir Seismological Array.

Answer

We recognise and are aware of the interference that onshore wind turbines can cause to seismological monitoring stations, and the subsequent safeguarding concerns that operators of seismological arrays can have. We are working closely with the Ministry of Defence to bring forward a resolution to this issue, via the Eskdalemuir Working Group. We are clear that the Eskdalemuir Seismic Array is a key piece of defence infrastructure that is part of international monitoring networks and that any updated approach to managing onshore wind deployment near the Array will not compromise its detection capabilities.
