Over £3.5 million funding from Government to reduce the impact of offshore windfarms on UK Air Defence

• The Department for Energy Security and Net Zero and DASA has awarded £3.2 million in funding to minimise the impact of offshore windfarms on UK Air Defence.
• The funding will be used to help develop prototype demonstrations of windfarm mitigating technologies such as new materials and sensor technology.
• A further competition has also launched today, with up to £500,000 in funding available for innovators with expertise in modelling and testing the effectiveness of different mitigation technologies.

Another significant boost to the UK’s renewable energy expansion has been delivered today, with fresh multi-million-pound Government funding and the launch of a new competition driving the move to minimise the impact of offshore windfarms on UK Air Defence surveillance.

Funding worth £3.2 million has been awarded by the Defence and Security Accelerator (DASA), in partnership with the Department for Energy Security and Net Zero (DESNZ), to two projects aiming to demonstrate technologies which can mitigate offshore windfarms’ impacts and their interference on defence radar.

Alongside this a new £500,000 competition has been launched which will help companies find solutions to accurately model and test the effectiveness of these technologies.

This will help ensure the UK remains on course to reach its ambition of 50GW in offshore wind by 2030, whilst supporting and co-existing with our air defence capabilities.

The Windfarm Mitigation for UK Air Defence: Phase 3 Programme is funded by the government’s £1 billion Net Zero Innovation Portfolio (NZIP) and is undertaken in partnership with the Royal Air Force (RAF), the Defence Science and Technology Laboratory (Dstl), and DASA.

Energy Security Secretary Grant Shapps said:

“Putin’s illegal invasion of Ukraine has shown us how important it is to power more of Britain from Britain.”

“Our offshore wind capability plays a huge role in delivering our energy security, with world’s four largest offshore windfarms in UK waters.”

“But with the war raging on, we need to make sure our energy security and our national security remain fully compatible.”

“This funding will ensure our offshore wind works alongside our latest air defence technologies – boosting our defences through our military, and by delivering home-grown energy for our homes and businesses.”

The first winner of the funding today is LiveLink Aerospace, a Hampshire-based aerospace company, who have been awarded up to £1.3 million in funding.

Their project will address the challenge of radar clutter caused by the rotating blades of wind turbines, which can degrade the performance of air defence radars and surveillance systems.

The firm’s work comprises of developing a series of small low-cost and robust passive air defence sensors, which do not emit any signals themselves, and therefore do not interfere with the radar returns from wind turbines.

The second winner is Trelleborg, an engineering firm based in Nottinghamshire, which has been awarded up to £1.8 million in grant funding to deliver a project on the use of advanced materials in wind turbines to tackle radar interference. Trelleborg will use its existing expertise in manufacturing and engineering of stealth materials to deliver next-generation wind blades which will cause less interference with radars.

Key dates and funding

Also announced today, is up to £500,000 in funding now available for Stream 2 of Windfarm Mitigation for UK Air Defence: Phase 3.This phase seeks to provide funding for innovators with expertise in modelling and testing the effectiveness of different mitigation technologies, with the end goal of producing the best technology through the right combination of radar, materials and mapping software.

The deadline to submit a proposal is midday 24 October 2023 (BST).Read to full competition document to submit a proposal.

The Windfarm Mitigation for UK Air Defence Programme

As part of the UK’s renewable energy supply to achieve Net Zero goals, offshore wind energy will be essential. However, the installation of offshore windfarms may cause detrimental effects on the quality of data gathered from surveillance radars, which are crucial for the UK’s air defence detection capability.

The Windfarm Mitigation for UK Air Defence programme has been addressing this challenge area for several years. After the successful completion of Phase 1 and Phase 2, Stream 1 of Phase 3 was launched earlier this year. The primary objective of Stream 1 is to support prototype demonstration of the technologies that could mitigate the impact of windfarms on UK Air Defence.

Stream 2 aims to find innovative solutions that can accurately model and test the effectiveness of different mitigation technologies.

Wing Commander Kevin Walton, Co-Chair of the Ministry of Defence/Offshore Wind Industry Council Air Defence Mitigation Task Force said:

“The MOD is playing an active role in the UK’s efforts to build a greener, net-zero future.

“Offshore wind will play a central part in meeting our nation’s renewable energy needs and ensuring energy security for the UK. Complementing existing RAF work to mitigate the impacts of large-scale offshore windfarms on our current radars and the previous phases of this competition, this 2nd stream of Phase 3 of the innovation competition will play an important part in helping us to find the right combination of future solutions that will enable the long-term co-existence of windfarms and the UK’s air surveillance radars.”

Windfarm Mitigation for UK Air Defence Programme: Phase 3 – Stream 2

To support the decision making on further development of windfarm mitigation technologies, it is necessary to develop a model which can be used to objectively compare the funded solutions, determine their effectiveness in reducing the impact of proposed offshore windfarm developments and predict the consequences and benefits of combining solutions together.

For this competition, we are seeking models that can help assess the performance of different windfarm mitigation technologies to inform future policy decisions. The model should be able to assess the technologies and combinations against a set of specific metrics, data, and different scenarios.

Example scenarios include:

• Several military jets crossing over a windfarm
• A fast jet performing a turn over a windfarm
• A supersonic fast jet traversing a windfarm at high/low altitude

Example metrics include:

• Percentage of time over a windfarm that the target remains tracked
• Time to re-establish tracking if lost
• Delay of any tracking.
