Munich, GERMANY - The three systems are scheduled to be commissioned in 2025.

Siemens Energy has announced that the German-Dutch grid operator TenneT has commissioned Siemens Energy to supply three grid stabilization systems for the German power grid. As more and more conventional power plants are taken off the grid and replaced by electricity from decentralized renewable energy sources as part of the energy transition, transmission system operators will have to find alternative solutions to transport more energy while maintaining overall stability.

According to Siemens Energy, two of the three systems are synchronous condensers. A synchronous condenser essentially consists of a generator and a flywheel. The third of the three solutions is the world's first reactive power compensation system with supercapacitors. It will use short-term storage in the form of supercapacitors. The supercapacitors can counteract fluctuations in the grid frequency either by actively charging themselves for a short time, thereby withdrawing up to 200 megawatts from the grid, or by feeding the stored power into the grid.

According to the company, Siemens Energy will build the solutions in Mehrum in Lower Saxony. This state produces by far the most onshore wind energy in Germany. The three systems are scheduled to be commissioned in 2025.
