When a park reaches the end of its life (20 to 30 years of operation for wind farms), questions about its future arise. Two solutions are then available: dismantle the farm and return the land to its natural state, or carry out a Repowering process.
The latter involves dismantling the park in order to renew it. This generally involves the use of more powerful and quieter turbines, but also better optimization of production (production data and the wind deposit are already known and analyzed over at least 20 years of service).
VSB and repowering !
VSB's expertise will support you in all aspects of power plant development, from the sale of electricity on the market to the «repowering» of installations and energy management using new technical and economic models.
We discuss the « repowering » of your power plants with an analysis of your sites to identify the best option to sustain and optimize energy production. Once this audit has been carried out, we will assist you in implementing this solution by supporting you in the development and construction operations.
«Install less to produce more! In Rivesaltes (66), VSB carried out its first repowering project on behalf of GEG ENR Company. By replacing 8 old turbines with 6 new ones of equal size, the power of the park has increased from 7.6 MW to 11MW »
1. Are all parks that have been issued with a purchase obligation eligible for a repowering operation ?
2. Does the repowering of a park require a new application for an environmental permit ?
The legal framework was clarified by a circular dated 11 July 2018. Substantial modification within the meaning of Article L181-14 of the Environmental Code or significant modification, in a certain number of cases the assessment is the responsibility of the Prefect. Initial feedback will make it possible to validate or even simplify the legal framework.
3. Repowering or revamping ?
Repowering makes it possible to benefit from existing infrastructures (access, delivery station, connection): however, it is a new project in its entirety that needs to be developed, financed and built. On the other hand, revamping only consists of changing certain parts of a turbine, or even an entire turbine within the same park.
