In its transmission grid area, 50Hertz Transmission GmbH has constructed a high voltage overhead line between Schwerin (substation Görries) and Geesthacht (substation Krümmel) near Hamburg. The final construction and connection works were performed on the line section in Schleswig-Holstein. The 380 kV overhead line was commissioned in 2012.
The so-called Wind Bus Bar is required to transport electricity, wind power for the most part, from the low-consumption coastal region to more inland regions consuming more electricity (especially Hamburg). With its construction, 50Hertz enables the further development of onshore and offshore wind power.
Other renewable sources of energy, however, will also benefit from the increased grid capacity. This includes biomass, which in North Germany already plays a more than average role in the generation of electricity. Furthermore, in Mecklenburg-Western Pomerania the Wind Bus Bar will substantially improve the 380 kV infrastructure. By connecting the 380/110 kV transformer substation of Görries over two independent overhead lines, the security of supply is improved for the entire west side of the Bundesland - more in particular for the state capital, Schwerin.
Moreover, the Wind Bus Bar establishes a link between the two regions with the highest generation of wind power in the drainage basins of the North and Baltic Sea. The electricity generation capacity of the wind turbines in this region is expected to rise exponentially in the years to come. 50Hertz is laying the groundwork for this infrastructure: when completed, 50Hertz Transmission GmbH will have invested about 93 million EUR in the new connection, having a length of some 88 km.
The Wind Bus Bar runs along national highway A24 for most of its length. The starting point is the Görries substation near Schwerin. From here on out, the route goes in south-westerly direction, then veers off west, running parallel to the A24, through the district of Ludwigslust-Parchim and finally reaching the state border south of Zarrentin. It then heads north-west through the district of Herzogtum Lauenburg along the highway in the direction of Geesthacht. Finally, it takes a bend to the south to Geesthacht, towards the Krümmel substation. The Wind Bus Bar totals 88 kilometres in length.
The construction work for the Wind Bus Bar was completed and the 380 kV line was commissioned in December 2012. After the plan approval procedure for the Mecklenburg-Western Pomerania section was concluded in 2009, the plan for the Schleswig-Holstein line was approved in late April 2012. Since then, we worked hard to link the completed eastern route section to the connection between the state border and Krümmel. Commissioning took place on 18 December 2012.
After the two-year regional planning procedure from 2005 to 2007, the plan approval procedure was concluded after another two years in September 2009. Subsequently, the line was completed up to the state border in July 2010. At the same time, the 110 kV line, supported by the same pylons, could also be commissioned.
After the regional planning procedure was concluded in 2005, approval was granted in the four-year plan approval procedure by the State Company for Road Construction and Transport in Kiel in April 2012. Following the conclusion of all negotiations with the land owners to secure the property rights, the construction works for the line began in the spring of 2012. By now, all pylons are in place and all conductors installed.
