Annual yield

The dismantling of an old wind turbine using a construction crane. The blades of the wind turbine are being separated from the rest of the structure and are still hovering at the level of the nacelle.

The project

In the repowering project in the Alzey-Worms district, we replaced five old turbines of the Spiesheim wind farm. These old turbines were errected in 1997 with a modell of the latest generation (Enercon E-40) and each with a capacity of 500 kilowatts. The new turbines have a nominal capacity of 5.6 megawatts, a rotor diameter of 150 meters and a total height of almost 250 meters and, therefore, alone generate almost four times the output of all five old turbines combined.

In front of the construction crane lie the now dismantled blades of the wind turbine. Compared to modern turbines, they appear tiny. In the background, the stump of the tower of the old turbine is still visible.

Technology makes the difference

The technology surrounding renewable energies is advancing rapidly: we take advantage of this for the optimization of plant locations within the scope of repowering projects. For more yield, more added value and even more climate protection.
