The approval and construction of substations is subject to the Federal Immission Control Act (BImSchG) and are therefore different from the approval procedure for a 380-kV overhead line.
The application for a permit under the BImSchG for the construction of a new 380/110-kV outdoor switchyard was submitted on 14 November 2013. On 5 September 2014, the competent environmental department of the Wittenberg district approved the project and as such granted the building permit for the project.
The selected location is best suited for the construction of a 380-kV overhead line, so that the construction works do not affect nature conservation areas or other ecologically valuable areas.
In January 2015, the application documents for the 380-kV overhead line were submitted to the Administrative Office of Saxony-Anhalt. After a thorough review of the documents, the authority decided to release the 380-kV overhead line from the planning approval proceedings and approved the plan that was submitted.
In consultation with the local public authorities and the land owners, the Administrative Office was able to confirm the route corridor established by 50Hertz.
The construction permit for the 380-kV grid connection was granted in late January 2015.
