The power line from Wilhelmshaven on the German North Sea coast to the Conneforde substation in Ammerland, both in the federal state of Lower Saxony, is one of those line projects in Germany that are urgently needed to extend the transmission capacities for wind energy from northern Germany to the consumption centres in the south and west. Moreover, the 380kV line is one of the German pilot projects for partial underground cabling in the three-phase current range. It will be around 30km long and comprise 60 pylons. In two sections, underground cables will be laid over a length of around 5.3km.
TSCNET shareholder TenneT has now begun construction of the new line with a symbolic turning of the first sod in Conneforde. The Dutch-German transmission system operator (TSO) by no means celebrated its first new construction in recent times: “This is already the fifth grid expansion project in Lower Saxony for which we can officially start construction within one year,” explains Lex Hartman, Managing Director of TenneT. Also the Fedderwarden substation (near Wilhelmshaven) is yet to be built. The scheduled commissioning date for line and substation is 2020.
To create transparency in the design process, TenneT involved the interested public, citizens as well as public stakeholders, much more in the planning than the formal procedure would have prescribed. In three years, the TSO has organised nine information markets along the route and conducted numerous individual discussions. “It is our central concern to harmonise our projects as closely as possible with the country and its people, while realising a secure energy supply for the benefit of electricity consumers,” explains Mr Hartman.
