Repowering: EDF Renewables commissions a fully renewed wind farm in Germany

EDF Renewables in Germany is announcing the repowering of the Eckolstädt wind farm, the first in a series to come. “Repowering” or renewing means the refurbishment of a facility that has reached the end of its life cycle. The Eckolstädt wind farm initially had an installed capacity of 14.5 MW, which has now been increased to 34.5 MW. This repowering project contributes to the EDF Group’s CAP 2030 strategy, which is aimed at doubling its worldwide renewable capacity to 50 GW between 2015 and 2030.

The Eckolstädt wind farm is located in Thuringia, Germany. Developed and commissioned by EDF Renewables in 1999, it initially consisted of 11 first-generation wind turbines. After obtaining planning permission and benefiting from a 20-year Power Purchase Agreement contract in late 2016, Eckolstädt’s wind turbines were fully dismantled by REETEC, an EDF Renewables’ subsidiary, in early 2018. The wind turbines’ components were mostly recycled and the foundations were crushed to be used as backfill for the platforms of new projects and surrounding roads.

The wind farm was then rebuilt on the same site and now consists of 10 new-generation wind turbines. The output generated by the wind farm is enough to meet the electricity needs of almost 18,500 German households.

The six-month repowering project was managed by EDF Renewables in Germany. Installed capacity has been increased by 20 MW to 34.5 MW with a smaller number of turbines.

EDF Renewables is currently assessing other repowering projects in Germany where there is a potential of 4.5 GW or 6,000 wind turbines* to be refurbished by the end of 2020, and around 1,600 wind turbines per year between 2021 and 2026. In France, EDF Renewables is also actively evaluating four repowering projects.

With the growing number of wind farms due to reach the end of their life-cycle between 2020 and 2030 – representing an installed capacity of around 76 GW across Europe** – repowering is a growth industry in which EDF Renewables has been developing its expertise over the last few years.

*According to the Deutsche WindGuard  study: „Weiterbetrieb von Windenergieanlagen nach 2020“.
**According to the WindEurope association, almost half of the European Union’s installed wind power capacity – 141.6 GW in 2015 – is due to reach the end of its life between 2020 and 2030.

Project Development & Execution

17 Jan | ACCIONA completely renovated wind farm service Spain

  • El Cabrito, located at Tarifa (Cadiz), goes from ninety 330-kW wind turbines installed in 1995 to twelve 3-MW and 1.5-MW machines of Nordex technology
  • The installation will produce 16% more clean energy with the same capacity (30 MW) as the obsolete wind farm
  • The renewal has reduced its environmental impact, as well as its visual and noise profile, and makes it easier for birdlife to fly through.

08 Jan | Nexans completes high voltage cable project to connect Kype Muir wind farm to Scotland’s power grid

The Scottish Government has set an ambitious target for renewable energy resources to meet 100 percent of the country’s gross annual electricity consumption by 2020. Large onshore wind farms will play a key role in meeting this target, such as the 88 megawatt (MW) Kype Muir wind farm, where Nexans has just completed a project to provide a 16 km 132 kilovolt (kV) underground grid connection for SP Energy Networks.
