VSB Group Powers Ahead with Major Wind Farm Repowering Milestone

VSB Group Connects One of Europe's Largest Repowering Projects to the Grid

The VSB Group has successfully connected the Repowering Wind Farm Elster to the grid. This impressive project, with an installed capacity of 105.6 megawatts, stands among the largest repowering projects in Europe. The energy output has increased sixfold compared to the original site due to modern turbine technology.

Generating Efficiency and Sustainability

The new wind farm produces 235 gigawatt hours of electricity annually, enough to power around 67,000 three-person households—similar to a city the size of Heidelberg. Dr. Felix Grolman, CEO of VSB Group, emphasizes that every bit of energy produced enhances Europe’s energy independence and contributes to meeting critical climate goals.

Revolutionary Approach to Repowering

With a staggering efficiency increase of nearly 600 percent, the Elster site serves as a potent demonstration of the potential of repowering. This strategy is promising in nations where older turbines are still operational.

Future-Proofing Existing Wind Farm Sites

The history of VSB’s involvement at Elster spans over two decades. From autumn 2021 to autumn 2022, the old turbines were dismantled, with many components being reused for spare parts or relocated for continued use.

According to Thomas Winkler, Managing Director of VSB Germany, the project faced challenges at every stage, from grid connection to dismantling. He noted that the successful outcome showcases how existing sites can evolve meaningfully through experience and collaboration with local entities.

Utilizing Advanced European Technology

The 16 SG 6.6-155 turbines utilized in this project come from the reputable European manufacturer Siemens Gamesa. Christian Essiger, Head of Onshore Business in Germany at Siemens Gamesa, mentions that modern turbines generate significantly higher yields while using less land, greatly enhancing climate protection efforts.

A Commitment to Expansion

This autumn, the wind farm will see the addition of two more turbines. Grolman envisions a clear future path: fewer turbines yielding more energy while utilizing land effectively—a strategy crucial for the strength of the European wind industry.

Comparing Old and New Wind Technology

The efficiency of these new turbines compared to those they replaced is remarkable:
