Wind farm would cause radar 'interference' - MOD Getty Images RAF aircraft can often be seen on training exercises in the Yorkshire Dales (stock image) Louise Fewster Yorkshire 10 October 2026 The Ministry of Defence (MOD) has objected to plans for a wind farm on moorland near the Yorkshire Dales, claiming it would cause "unacceptable interference" to radar.

Fred. Olsen Renewables is seeking permission to build 23 turbines more than 200m (656ft) high on land between Arkengarthdale and Teesdale. The MOD stated it would also cause a "physical obstruction" to low-flying aircraft.

The renewable energy developer said it was working with the MOD, other stakeholders and the local community to address potential impacts and find "practical solutions where needed".

The MOD raised its concerns about the size and location of the proposed wind farm in a letter to the national Planning Inspectorate.

It says the turbines would impact the Royal Air Force's (RAF) ability to "detect and deter aircraft" in UK airspace.

In its submission, the MOD says it would cause "unacceptable interference" to air defence radar about 67 miles (108 km) away at Remote Radar Head Brizlee Wood in Northumberland.

It says it would also impact the air traffic control radar about 19 miles away (30 km) at RAF Leeming.

It adds that it would create "false radar returns" and also result in real aircraft "not being detected". It also warns that the turbines would be in an RAF low-flying area.

LDRS/Hope Moor Wind Farm Action Group Hope Moor Wind Farm would see 23 turbines built on moorland The Department for Energy Security and Net Zero ended the ban on new onshore wind farms when Labour came to power in 2024. That meant that wind farms were prioritised as a Nationally Significant Infrastructure Project.

The government said its strategy for easing planning rules was crucial to achieving clean power targets by 2030.

The MOD has also objected to proposals for a wind farm in the East Yorkshire Wolds claiming it would impact air defences and jet pilot training exercises.

Local people have voiced their concerns over the proposal, with campaigners calling it the "devastating industrialisation" of Yorkshire Dales moorland.

Councillor Angus Thompson, who has helped to lead the campaign against the wind farm, said that the MOD's "stark warning is the nail in the coffin for this scheme".

"The MOD considers that these monster turbines threaten national security and the lives of pilots," he said.

"This hopeless project should be abandoned without delay." The developer argues the scheme could generate enough renewable electricity to power about 135,000 homes while helping meet climate targets.

Euan Hutchison, UK development director at Fred. Olsen Renewables, said Hope Moor could help in reducing reliance on imported energy and deliver a more secure and affordable energy system. "We also believe national security and energy security go hand in hand," he said.

He encouraged residents, businesses and community groups to submit feedback as plans for the development continue to be refined. A decision on whether the development will go ahead will eventually be decided by the Secretary of State for Energy.
