Home/Grid The transmission grid of 50Hertz Maintenance in the substation, works on 380-Kilovolt- overhead line from 50Hertz in South Brandenburg. Image rights: 50Hertz Our grid’s power circuit length covers a distance of 10,490 kilometres across the entire eastern part of Germany as well as Berlin and Hamburg. We transport a constantly increasing share of renewable energy over large distances at the extra high-voltage levels of 150, 220 and 380 kilovolts (kV). In substations, we exchange electricity with the distribution system operators; here, transformers convert electrical energy from one voltage level to another. Large producing units such as power plants or wind farms (onshore and offshore) as well as large industrial companies such as steel mills are directly connected to our extra high-voltage grid. We constantly maintain our lines and substations and repair damage resulting from old age or storms, for example.
