MoD Windfarm Objections: Radar Interference Threatens UK Energy Goals 2026

The Ministry of Defence (MoD) has objected to at least four planned windfarms in the past year over radar interference fears, potentially jeopardizing the UK's renewable energy targets. These objections, based on national security concerns, highlight a growing conflict between energy infrastructure and military operations.

MoD's Objections: A Closer Look

The MoD's primary concern is that spinning turbine blades could cause unacceptable interference with radar systems used to detect military aircraft. In late June, officials raised alarms about the Hope Moor project in County Durham, a proposed onshore windfarm with 23 turbines reaching 200 meters in height. According to a letter to the planning authority, the turbines could result in aircraft "not being detected" within an RAF Low Flying Area.

This objection is the latest in a series of at least four made on national security grounds in the last year. Other projects facing MoD opposition include the Burton Agnes windfarm in East Yorkshire and a 13-turbine development in Scotland, where the risk was deemed "unmanageable." The background to this story is set out in Onshore Windfarm Applications Hit 10-Year High in England. A related thread runs through Offshore Windfarm Threatens Bass Rock Seabirds. Earlier coverage in Renewable Energy Quiz: Test Your Knowledge Today shows how the argument developed.

Impact on UK Energy Goals

The MoD's objections put it on a collision course with the Department for Energy Security and Net Zero (DESNZ). In 2024, the Labour government lifted a decade-long block on onshore wind developments in England, aiming to double the UK's onshore wind capacity by 2030. Hope Moor has been designated a nationally significant project, with its fate to be decided by the energy secretary.

This conflict underscores the challenge of balancing national security with renewable energy expansion. While the government pushes for cleaner energy, the MoD insists on protecting radar capabilities critical for defense.
