Above and beyond – From the depths of coal mines to sky-high wind turbines

Germany is turning a former coal mine in Lusatia, in the state of Brandenburg, into a center for renewable energy with Gicon’s construction of what will soon be the world’s tallest onshore wind turbine.

Gicon, a Dresden-based engineering and environmental consulting firm, specializes in renewable energy solutions and environmental protection technologies. Its 364-meter wind turbine at the Lusatia coal site will be the second tallest structure in Germany (after the Berlin TV Tower) and serves as a symbol of the country’s shift away from coal dependency. The Klettwitz wind park, where the new turbine is being constructed, already integrates existing wind turbines and photovoltaic panels, forming a hybrid renewable energy facility.

This turbine, positioned on a four-legged lattice tower, is designed to generate twice the power of standard models with the same rotor diameter by capturing stronger winds at higher altitudes. A notable feature is its telescopic system, which allows it to be built at a lower height and then raised to its full 364 meters — beyond the reach of cranes.

Gicon’s plans extend beyond this single turbine. The company aims to install 1,000 similar turbines across Germany by 2030, focusing on former open-cast coal mines, particularly in Bavaria. These taller turbines are designed to increase energy output without needing additional land, as they coexist with current wind turbines. According to Gicon’s founder, Jochen Grossmann, the new turbines won’t disrupt wind flow to the machines below, enabling multi-layered energy production. The technology could also be applied in regions with less wind, potentially expanding the global use of wind energy.

Unlike other wind turbine projects, there was no pushback from residents, as Gicon engaged the community early and kept them informed about the plans. The foundation stone was laid in September 2024, and operations are expected to begin by summer 2025.
