VSB Group has completed the grid connection of its 105MW Elster repowering project in Saxony-Anhalt, marking a significant step in Europe’s renewable energy transition. The wind farm, now equipped with 16 Siemens Gamesa SG 6.6-155 turbines, is expected to generate 235GWh annually, enough to power 67,000 households, according to VSB.
The project replaces 50 Enercon E-40 turbines, originally installed between 2000 and 2002. VSB dismantled the legacy units between 2021 and 2022, reusing many components as spare parts or in continued operation elsewhere. This approach underscores the industry’s growing focus on circular economy principles, where the lifecycle of wind turbines is extended through reuse and recycling.
“Every kilowatt hour from Repowering Wind Farm Elster strengthens Europe’s energy sovereignty and brings us closer to achieving the EU’s climate targets,” said Chief Executive Felix Grolman. The project’s completion comes at a critical time, as Europe seeks to reduce its dependence on fossil fuels and accelerate its green energy transition.
The new Siemens Gamesa turbines stand 242.5 metres tall, with a blade length of 77.5 metres. “Modern turbines like the SG 6.6-155 deliver higher yields using less land – and make a clearly measurable contribution to climate protection,” said Christian Essiger, head of onshore business in Germany at Siemens Gamesa.
The project’s success highlights the importance of long-standing experience and close cooperation with local partners and authorities. “Grid connection, permitting, dismantling – the project posed significant challenges in every phase. Its successful completion shows how existing sites can be future-proofed,” said Thomas Winkler, Managing Director of VSB Germany.
VSB plans to add two additional turbines at the Elster site in autumn 2025, further increasing the farm’s capacity. “Fewer turbines, more output, and smart use of available land – that’s the key to a strong European wind industry,” Grolman added.
The Elster repowering project serves as a model for the wind industry, demonstrating how technological advancements and strategic planning can optimize energy generation and contribute to Europe’s climate goals. As the sector continues to evolve, such projects will play a pivotal role in shaping the future of renewable energy in Europe.
