Enercity Erneuerbare GmbH announced plans to build the Klettwitz 2.2 onshore wind farm in the Lusatia lignite mining district in Klettwitz in Brandenburg, Germany.
The project is an extension of the Klettwitz 2.1 wind park and will have a capacity of 33 MW. The German municipal utility said Vestas Wind Systems A/S will deliver and install 10 wind turbines for the project, of which five will be commissioned by the end of 2019.
The company said in an Aug. 15 news release that soil conditions on brown coal dumps require special expertise to create sustainable turbine foundations. "The sandy soils can get in motion in connection with groundwater," enercity Managing Director Ivo Grünhagen said. He added that soil compaction driven up to 90 meters deep will secure the turbine foundations.
After completing the project by February 2020, the total output of Klettwitz 2.1 and Klettwitz 2.2 will be about 53.5 MW.
Hanover, Germany-based enercity is a subsidiary of Versorgungs- und Verkehrsgesellschaft Hannover mbH. It supplies about 560 GWh of electricity and plans to boost its wind energy production to up to 2,000 GWh.
