Defence Ministry Objects to Hope Moor Wind Farm Over Military Radar Concerns
Developing story first seen 54 minutes ago
The Ministry of Defence has objected to plans for the Hope Moor wind farm in County Durham, warning that its turbines could interfere with military radar and leave aircraft undetected in an RAF low-flying area. The objection is the latest in a series of defence concerns that could complicate the government’s plans to expand onshore wind in England.
Hope Moor could comprise 23 turbines up to 200 metres tall and has been designated a nationally significant project, meaning the energy secretary will decide its fate. The MoD has raised concerns about at least four wind farms in the past year, including projects in East Yorkshire and near the Scottish border, as well as an 87-turbine offshore proposal in the Irish Sea. Industry representatives say radar concerns are often resolved through changes to turbine size or height, while the government says defence, community and environmental impacts are assessed through planning.
- MoD says Hope Moor turbines could affect military radar.
- The project has 23 turbines planned, up to 200 metres tall.
- Radar concerns have been raised about at least four wind farms in a year.

The UK is expanding onshore wind farms as part of its renewable energy strategy. The proposed Hope Moor project in County Durham would include 23 turbines up to 200 metres tall. The Ministry of Defence has objected to the plan, warning that the turbines could interfere with military radar systems.
Military radar is essential for detecting aircraft safely, particularly in areas designated for RAF low-flying training. If wind turbines disrupt this radar, it could compromise aircraft detection in those zones, creating a potential safety concern. The MoD has raised similar concerns about other wind farm proposals in recent months.
Because Hope Moor is classified as a nationally significant project, the energy secretary will make the final decision rather than local planners. Defence impacts will be assessed alongside environmental and community concerns as part of the planning process. Industry representatives suggest that radar concerns can often be resolved through adjustments to turbine height or design.
Both sides, in good faith
The strongest fair case each way — we don't pick a winner.
The case for
The government must dramatically accelerate renewable energy deployment to meet climate targets and bolster energy security amid geopolitical uncertainty. Industry representatives argue that radar interference concerns can be mitigated through modifications to turbine design or placement, with previous projects successfully resolving such issues. Designating Hope Moor as nationally significant reflects the assessment that energy supply is a critical infrastructure priority for the nation's prosperity and security.
The case against
The Ministry of Defence has a fundamental responsibility to protect airspace and maintain military operational capability, particularly in active low-flying training areas where radar detection is essential for aviation safety. Large turbines can materially interfere with radar systems in ways that cannot be easily undone once installed, and the fact that the MoD has raised concerns about at least four separate projects in one year suggests this represents a systemic problem rather than an isolated case that can be readily solved through minor modifications.
