Repowering with ENERTRAG: Proven location. New wind turbine.
Modern wind turbines generate a higher electricity yield, secure long-term income and advance the energy transition in your region. Find out how repowering can make your sites fit for the future.
What is repowering?
Older wind turbines are replaced by modern turbines. This increases the electricity yield, secures long-term income and continues to use existing sites for the future.

Repowering leads to ...
- higher energy yields
- more efficient use of space
- better economic efficiency thanks to modern technology
- often fewer wind turbines in the wind farm
- added value remains in the region
- improved grid integration thanks to grid-friendly new wind turbines
- an effective contribution to climate protection
What are the advantages of repowering?
The repowering process with ENERTRAG
We start with a free potential analysis and check existing wind turbines for their repowering capability. This includes checking the eligibility for approval of new turbines and, for example, the availability of land and the economic potential. Together with you, we develop the right path to your successful repowering.
From old to efficient - rock'n roll in the wind farm with ENERTRAG
How existing wind sites can be efficiently renewed with modern technology: more electricity yield, fewer turbines, lower costs and maximum benefits for operators, investors and the energy transition.

What you should bring to the interview:
Our checklist will help you to assess whether repowering could make sense for you:
- Site information (location, area)
- Current key figures on energy generation
- Overview of existing turbines (year of construction, type, output)
- Contract details (e.g. terms)
- Information on any restrictions (construction height, species protection)
