So, another frequency/voltage stabilization project, but not mass storage to reduce the need or fossil-fuel plants.. . . The storage systems are to be used to provide primary control power—a service for stabilization of the networks—for which the Transmission System Operators invite bids on a weekly basis. Primary control serves to stabilize the network frequency when there are short-term fluctuations in the grid (caused, for example, by uneven feed-in of energy from renewable sources which deviates from the forecasts, by power plant outage or by fluctuations in consumption). The six systems are to be operated independently of the STEAG power plants and are capable of relieving the grid fully automatically within a few seconds when there is surplus supply, and also in reverse feeding energy into the grid.
- Storage facilities and the creation of flexibility are essential elements in the implementation of the energy transition in Germany. STEAG has therefore decided to make this investment in large-scale batteries for deployment on the control power market, without making use of grants or subsidies.
—Joachim Rumstadt, Chairman of the Board of Management of STEAG GmbH
STEAG’s large-scale batteries will satisfy the current performance criteria for battery storage systems supplying primary control power—e.g., the requirement of being capable of providing primary control power for at least 30 minutes.
