The transmission system operator Amprion GmbH is a new partner of the Energieküste with its Korridor B project. We are very pleased that Amprion is enriching our network with this important building block for the energy turnaround. The first preliminary work for the construction of the 700 km long underground cable from the North Sea to North Rhine-Westphalia has begun, including water measurements.
Green energy for the Ruhr area
From around the beginning of the 2030s, Corridor B will supply northern German wind power to Germany's largest conurbation. Low-loss extra-high voltage direct current (HVDC) technology with a nominal DC voltage of 525 kilovolts will be used. The transmission capacity of the high-power cables, which will mainly run underground, is four gigawatts in total. Corridor B can arithmetically supply four to five million households sustainably, therefore a large part of the 5.1 million inhabitants of the "Pott".
The mammoth project consists of two parts: Line Construction Project No. 48 (Heide/West - Polsum) and No. 49 (Wilhelmshaven - Hamm) of the Federal Demand Plan Act. With the trend-setting Corridor B, the energy of shut-down coal-fired power plants in the Ruhr area will be replaced - a major step towards Germany's climate-neutral future.
Amprion, one of four transmission system operators in the Federal Republic, will also contribute to the energy transition with further projects on the Energieküste. On the occasion of the 2nd Energieküste Infrastructure Forum, Amprion signed a cooperation agreement on the expansion of power lines in the Dithmarschen region. The cooperation of a total of five partners includes joint guidelines from the district, grid operators and the state, which are intended to accelerate the expansion of power lines in Dithmarschen.
