Public participation

SuedOstLink: continuous dialogue improves the planning results

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:

  • The “planning forum” (Planungsforum) gathers politicians, representatives from regional and local administration as well as experts from environmental or economical associations from the federal states of Saxony-Anhalt, Saxony and Thuringia. The aim is not only to give first-hand insight into the planning process for SuedOstLink, but also to get direct feedback from an expert audience. Since summer 2016 three “planning forums” have taken place.
  • “Information markets” are put up in town halls of larger municipalities across the planning region. Town representatives as well as the broad public are invited to get an update on the project and to give feedback on the respective planning status. A tour of ten “information markets” has taken place in autumn 2017 – aim was to get feedback on identified route corridors in order to improve the planning before submission.
  • The format of the “info-tour” addresses the same groups as the “information markets”, but instead of town halls a modified lorry, the “DialogMobil”, is used open-air to join local markets days or be present in frequented pedestrian area. An “info-tour” was held in Spring 2017 to inform on the content of the submitted planning application for SuedOstLink.

Important: All events, the shown maps and material as well as the received feedback are documented on the SuedOstLink web-page.

Third Planning Forum in Halle on 8 March 2017

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.

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.

Information markets for the SuedOstLink

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.

Information tour

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.

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.

Soil protection

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.

Protect valuable soils in the best possible way

Soil protection during corridor search and route planning

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.

Soil protection during construction planning

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.

Cable route in the construction phase with site road, and separately removed and stored excavated soil

Soil protection on the construction site

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.
