Repowering
Repowering is the key to creating a cleaner, more resilient power system by 2030
The big picture
Behind every repowering project are real outcomes — more clean energy, more jobs, and stronger communities.
12%

How Nadara is leading repowering
Through repowering Nadara's ageing wind turbines, we could power an extra three million UK homes.
Learn about repowering
What is repowering?
Repowering is the process of upgrading ageing onshore wind turbines, responsible for generating around 12% of the UK’s electricity generation, by upgrading and/or replacing older turbines with modern, more efficient models while reusing much of the existing infrastructure.
Instead of dismantling wind farms at the end of their ~ 25-year lifecycle, repowering can extend value, boost energy output by between 3 and 10 times, reduce environmental impact, and ensure a consistent supply of secure, home-grown renewable power to support the UK’s energy transition.
How does repowering work?
Through repowering Nadaras aging wind turbines, we could power and extra 3 million UK homes.
Repowering can often reuse much of the existing infrastructure, such as roads, cabling, and grid connections, to upgrade existing onshore wind farms. Depending on the site, this can mean fully or partially replacing older machines with new-generation models capable of producing between 3 and 10 times more renewable energy.
Just as important as the technical upgrades are the environmental and community considerations. Every repowering project includes thorough noise, visual, and biodiversity assessments, ensuring wildlife, landscapes, and local resources are protected.
At Nadara, we place communities at the heart of the process, listening, engaging, and investing, so that repowering not only delivers cleaner, more reliable power but also lasting benefits for the people and places that host our wind farms.
Nadaras commitment
With 1 GW of installed onshore wind capacity and some of the UK’s oldest wind farms under operation, Nadara is at the forefront of making repowering a reality.
Why is repowering important?
Repowering is central to the UK government’s Clean Power 2030 strategy, which targets 27–29 GW of onshore wind capacity by 2030 and 35–37 GW by 2035. Without repowering, up to 9 GW of capacity could be lost by 2050, undermining progress towards climate and energy security goals.
Repowering can also reinforce:
- Energy security: providing consistent, home-grown electricity as demand surges through the 2030s.
- Faster decarbonisation: extending the life of existing wind farms reduces the need to build new projects on untouched land.
- Community resilience: projects continue to deliver local investment, shared ownership opportunities, and community benefits.
