The German transmission system operators (TSOs) have to react with innovative technology to the changes in the German energy landscape caused by the shutdown of nuclear and other large power plants in the course of the energy transition. An important issue is the loss of reactive power, and an appropriate technological response are rotating phase shifters, which are highly efficient and flexible in the provision of reactive power to maintain voltage.
TSCNET shareholder Amprion has now commissioned such a high-performance system at its Illingen-Uchtelfangen substation in the German federal state of Saarland. It is the second rotating phase shifter in the Amprion grid after the TSO commissioned the first one in September 2018 in Oberottmarshausen (Bavarian Swabia). Amprion has invested €60m in the new state-of-the-art equipment, which keeps the transmission grid stable and thus further increases supply security in Saarland.
The commissioning ceremony was attended by Anke Rehlinger, Saarland Minister for Economic Affairs, Labour, Energy and Transport. Together with Amprion Managing Director Dr. Klaus Kleinekorte, General Manager of GE Grid Solutions Gerhard Seyrling and representatives of district and municipal politics, she pressed the “red button”, which symbolically put the facility into operation. Mrs Rehlinger commented on the new device: “Against the backdrop of the energy transition, grid stability and security of supply are becoming increasingly important. With the installation of the rotating phase shifter, Amprion is making an important contribution to the future of power transmission grids.”
