We are consistently working on the Success of the Energy Transition
As a transmission system operator, we ensure the electricity supply for around 18 million people in the north and east of Germany. Our high voltage grid has a power circuit length of approximately 10,200 kilometres. We keep up the condition of the lines and substations through efficient maintenance and repair, expand our grid based on the need and ensure the electrical balance between energy consumers and producers in our grid area at all times. Over 1,000 employees at eight locations ensure that electricity flows 24/7 in Berlin, Brandenburg, Hamburg, Mecklenburg-Western Pomerania, Saxony, Saxony-Anhalt and Thuringia.
With the energy transition, the energy system has fundamentally changed. Increasingly, renewable energies are fed into our grid, either directly or via the distribution grids, and have to be transported via our lines. Already today, the share of renewable energies in electricity consumption in the 50Hertz grid area is calculated at over 53 percent. And this share will continue to grow. The 50Hertz grid is prepared to keep the region stable and provide a secure supply of power also in the future – because we are dedicated to successfully shaping the energy transition.
Our Electricity oscillitates at 50Hertz
50Hertz primarily transmits the energy in its grid using alternating current. This current changes its flow direction 100 times per second. Technically speaking, the current oscillates at a frequency of 50 hertz. Fluctuations in electricity generation and consumption have an impact on the frequency. The frequency falls if there is a power deficit and increases if there is a power surplus. To ensure that the frequency is always in the range of 49.8 and 50.2 hertz, we constantly balance the oscillations. In doing so, we always keep the system stable.
