Project status 1st section (Bad Lauchstädt - Vieselbach)
The first section was completed in 2008. Since then, the 380 kV overhead line between the substations of Bad Lauchstädt near Halle and Vieselbach near Erfurt has been in operation.
The overhead line is located on the territories of Saxony-Anhalt and Thuringia. As a result, the mandatory procedures are carried out by two Länder authorities. Within only two years, the spatial planning and plan approval had been concluded. Work commenced in February 2006, in Steigra (Saale district, Saxony-Anhalt).
The 380 kV route replaced a 220 kV line that had connected Bad Lauchstädt and the Vieselbach substation since the 1960s. The new EHV line therefore mostly follows the old route.
Project status 2nd section (Vieselbach - Altenfeld)
The second section between Vieselbach and Altenfeld is currently under construction. After the works were interrupted between February and August, 50Hertz recommenced construction of the second section in September 2012. In addition to the 380 kV line, 50Hertz is constructing a section of 110 kV line from the substation at Stadtilm to the 380 kV route for Thüringer Energienetze GmbH.
For the second section between Vieselbach and Altenfeld, the competent Thuringian Administrative Office in Weimar finalised the regional planning procedure on 30 March 2007 with its "state planning assessment". This was followed by the plan approval procedure. Approval for the plan was then granted on 31 January 2012.
Project status 3rd section (Altenfeld – Thuringian state border)
The plan approval procedure was officially initiated by the Thuringian Administrative Office on 19/09/2013. Between 7 October and 18 November 2013, the planning documents were available for consultation at the offices of the municipalities involved, namely: municipal association Großbreitenbach (Ilm-Kreis), municipal association Langer Berg (Ilm-Kreis), city of Langewiesen (Ilm-Kreis), municipal association Bergbahnregion/Schwarzatal (district Saalfeld-Rudolstadt), municipal association Lichtetal am Rennsteig (district Saalfeld-Rudolstadt), city of Bad Blankenburg (district Saalfeld-Rudolstadt), municipality of Masserberg (district Hildburghausen), city of Eisfeld (district Hildburghausen), city of Neuhaus am Rennweg (district Sonneberg), city of Schalkau (district Sonneberg), municipality of Frankenblick (district Sonneberg), municipality of Judenbach (district Sonneberg), municipal association Buttelstedt (Landkreis Weimarer Land).
50Hertz has now also published the planning documents online. They can be consulted here.
For the plan approval procedure, project developer 50Hertz drew up a detailed plan of the line route, containing the mast locations, a feasibility study for a possible partial underground cable solution in the Schalkau area and a landscape management plan, mentioning all effects on the environment and proposing compensation measures.
In the scope of the preparatory works, extensive discussions with the city and municipal administrations as well as the forestry authorities are necessary. 50Hertz takes account of the special topograhic conditions with wide span sections. These bridge valleys of up to 800 metres wide. The objective is to minimise the visibility of the pylons and the effects on the forest. To this end, technical calculations are currently being performed for the droop and for the construction of special pylons that can handle the enormous tractive forces.
The plan approval procedure was preceded by the regional planning procedure. To this end, the Thuringian Administrative Office in Weimar, which is responsible for the procedures, held a project conference in May 2006. Subsequently, an additional consulting round was held in February 2007. In January 2010, the regional planning procedure was formally initiated. During its course, alternative line routes were studied. The regional planning procedure was concluded with the state planning assessment on 30/03/2011.
TenneT TSO GmbH is the responsible transmission system operator for the construction work on the section from the Bavarian state border to Redwitz (to the project website).
