The German power transmission system operator (TSO) Amprion plans to invest around €12bn over the next five years, amounting to an increase of some 10% compared to the previous planning. Investments remain focused on expanding the important north-south axes of the transmission grid, such as the Corridor B project, which should transport 4 GW of wind power from northern Germany to the centres of consumption in the Ruhr area from 2030 and therefore to replace the capacity of five large coal-fired power plants. During the 2021 financial year, Amprion invested a record amount of €1.2bn in expanding its power grid infrastructure. The group started the planning approval procedures for the entire direct-current corridor in the A-North project, the northern part of DC corridor A from Lower Saxony to Baden-Wurttemberg.
