Wind turbines have a lifespan of 15 to 25 years. "Once a turbine has reached the end of its lifecycle, we are faced with three possibilities: extend its lifespan by about three to five years depending on the condition of the park, carry out a repowering operation, or if these two alternatives are not feasible, dismantle the park," explains Thomas Fabritius, VP of Operations for Renewables Europe.
Repowering? This term refers to the replacement of old wind turbines with more efficient models, allowing for an increase in a park's production without requiring additional land, and in some cases, even using less of the existing plot. "The increase in installed power is significant, ranging from +60% to +70% on average," emphasizes Thomas Fabritius. It's a sustainable approach contributing to ENGIE's objective of producing 80 GW of renewable energy by 2030 (compared to 38 GW today).
