All important questions on SuedOstLink are answered briefly and concisely in this leaflet to the Project.
On the basis of the study framework of the Federal Network Agency, the application for federal sectoral planning is revised and deepened. An information letter will provide information on the works and the supplemented route corridor Network.
Based on findings from application conferences in Magdeburg, Halle and Gera, the Federal Network Agency defined the scope of studies at the end of 2017. The study frameworks were drawn up separately according to sections:
A summary of the main contents of the application for federal sectoral planning (pursuant to § 6 of the Network Expansion Acceleration Act, NABEG) and the step-by-step planning processes from the study area to the definition of the corridors are bundled in the "executive summary".
The complete application for federal sectoral planning of March 2017 comprises more than 4000 pages and can be found on the website of the Federal Network Agency:
All through the planning and approval procedure 50Hertz keeps close contact to the public. Different formats, tailored for the various dialogue partners, ensure continuous information about the project’s status, gives the chance for exchange of ideas and arguments and allows to collect valuable regional and local information. Main aim of all activities is to review and improve the planning results in order to identify corridors and routes, holistically considering environmental and social aspects.
In the public participation for SuedOstLink 50Hertz uses three main formats:
Important: All events, the shown maps and material as well as the received feedback are documented on the SuedOstLink web-page.
On Wednesday, 8 March 2017, 50Hertz, together with project partner TenneT, submitted the application for federal sectoral planning for the direct current project SuedOstLink. On the same day, representatives from state politics, administration and associations from Saxony, Saxony-Anhalt and Thuringia informed themselves about the contents of the application at a planning forum in Halle.The maps and presentations shown at the Planning Forum are available for download below.
After checking that the application is complete, it will be published on the website of the Federal Network Agency responsible for the proceedings at www.netzausbau.de.
At the second planning forum for the SuedOstLink, the possible route corridor options for the northern area of the SuedOstLink were presented to the public for the first time. Those present were given an insight into the planning work of the past months. In working groups, they also had the opportunity to obtain information on the corridor options identified and to submit initial comments.
The first planning forum for the SuedOstLink was the prelude to the search for possible route corridor options for the SuedOstLink. Those present were given an insight into the methodology, the basic data and the status of technical planning for the underground cable Project.
Immediately after the publication of the first possible route corridor options at the end of September 2016, 50Hertz also discussed its plans with local citizens in the regions.
From 5 October to 3 November 2016, experts from 50Hertz visited ten locations between Wolmirstedt near Magdeburg and the Thuringian-Bavarian border with so-called information markets.
At the information markets, visitors were able to obtain information on topics such as permits, technology and environmental protection according to their personal interests.

SuedOstLink on site: 50Hertz provides information on ongoing planning
The current plans for the SuedOstLink direct current connection are the subject of an information tour of 50Hertz from 29 May to 20 June 2018. For this purpose, the transmission system operator visites squares and pedestrian zones in the planning area with its DialogMobil.
The representatives of 50Hertz give an overview of the additional studies that the leading Federal Network Agency has commissioned within the framework of the federal sectoral planning. These also include new, additional route corridor segments and an inspection for overhead line routing required for certain sections. Visitors are also able to obtain information on technical issues and the further course of the procedure.
The Information Tour to the SuedOstLink stops in:
Previously, 50Hertz conducted an information tour in the planning area of the SuedOstLinks in spring 2017. At that time, the project team had visited a total of 17 cities and municipalities 16 - 31 March 2017.
The SuedOstLink shall be mainly realised as an underground cable connection, as prescribed by law. A careful route search, the choice of the right laying technique and clear specifications for the construction teams ensure that the soils in Saxony-Anhalt, Saxony and Thuringia are spared as much as possible.
Soil protection has priority right from the planning stage: more than 50 individual criteria have to be considered during the search for a suitable route corridor. In addition to nature conservation areas with protected soils, for instance, mapping data on damp and easily compacted soils, moors, erosion-prone soils as well as soils with a particularly high natural fertility (e.g. black soils) are taken into account.
During the subsequent determination of the course of the underground cable trench, the route planners then take an even closer look. With detailed surveys and on-site visits, they determine the specific soil conditions. This is due to the fact that these can change within a few metres due to the geology, slope inclination or groundwater level.
Another important aspect of soil protection is the decision on how the cable will be laid under the ground. As a rule, the open trench method is used. In the case of the SuedOstLink, the cables can be laid in either one or two trenches depending on their number. A single trench makes the route narrow; however, with two parallel trenches vehicle movements may be less and better distributed, which helps prevent soil compaction.Another important option is trenchless installation. This allows protected areas to be undercut by up to 1,000 metre long drilled holes. A possible method to achieve this is horizontal directional drilling (HDD). However, parts of this method are very complex. Especially the larger surfaces required at the start and end points are often contrary to the actual protective purpose. Therefore, this method is only used for soil protection after careful consideration and in special cases.
But planning alone is not enough: for successful soil protection, the construction work itself is decisive. To this end, clear rules are already in place that prescribe what has to be done and what is not allowed. The implementation of these rules is the task of an ecological and pedological construction supervision as an advisory and control authority on site at the construction site.Effective soil protection already starts with the first work stage. The topsoil must be removed particularly gently and the different soil horizons must be removed separately. They must be stored separately so that they can later be reinstalled in the same stratification and not mixed. In order to maintain the soil structure, the stored excavated material needs protection from drying out by wind and sun.
Furthermore, the construction vehicles must not unnecessarily compact the subsoil. A proactive selection of machines with the lowest possible weight or with crawler tracks instead of wheels can keep the pressure and thus the soil compaction low. Additionally, underlay plates can distribute the pressure of heavy vehicles. Moreover, a thoughtful arrangement of the construction site keeps travel distances short and avoids unnecessary manoeuvring. In extreme cases, only an interruption can help: if the soil is very damp or subject to extreme weather influences, the construction works may need to be halted until the conditions have improved again.
