Energiequelle has begun work on a repowering project at the Bremen-Rekum wind farm in Germany to increase efficiency by around 800%.
Work to dismantle two old turbines has now started (pictured). The two Enercon E-66 wind turbines, each with an output of 1.8MW, will be replaced by two modern turbines.
The new Nordex N163 turbines have a rotor diameter of around 163 metres, a hub height of 164 metres and a generator output of 7MW per turbine.
This output will supply around 12,000 households and save more than 35,000 tonnes of carbon dioxide emissions.
Energiequelle submitted the application for approval for the two turbines in mid-January 2023 and received the positive decision at the end of 2023.
After rescheduling the access route due to a listed railroad track, the project was submitted to the onshore wind energy tender in August and was awarded a contract by the Federal Network Agency in mid-September.
Energiequelle project manager Felix Busse said: “Due to the proximity to a large wartime submarine bunker, we were busy clearing explosive ordnance for months.
“A preliminary archaeological investigation was also necessary, as the construction site is located in an area with archaeological potential.”
With the dismantling work now underway, construction of the new facilities is planned from the end of the year. Commissioning is scheduled for spring 2026.
