Siemens delivers battery storage systems to Stadtwerke Schwäbisch Hall
"The energy storage system complements our decentralized power generation plants very well. These plants cover 60 percent of total consumption in Schwäbisch Hall, and now consist of a disproportionately high share of renewables," says Gebhard Gentner, Managing Director of Stadtwerke Schwäbisch Hall. Stadtwerke Schwäbisch Hall is a medium-sized energy service company that currently supplies electricity, natural gas, water, and district heating to approximately 50,000 customers. The utility company additionally handles billing for approximately 115,000 contracts in the shared service area and provides energy services for more than 500,000 customers throughout Germany on behalf of power and natural gas distribution companies. With a workforce of around 500, the public utility generates revenue of about €260 million per year.
Siemens will install all components of the Siestorage battery storage system in a single container and deliver it to the customer on a turnkey basis. The modular solution consists of lithium-ion battery modules, inverters and transformers as well as the control system. The system is primarily intended to help the public utility company market primary control reserves. Additional application areas are in the planning stage.
Distributed power supply is increasing as Germany transitions to a new energy mix. Integrating more and more renewable energy sources in the grids causes the volatility to increase, the base load to decrease, medium- and peak-capacity demand to grow and power surpluses to occur with greater frequency. The grid operators need reserve power to establish a balance between generation and consumption at all times. The function of the primary control reserve is to immediately balance out unforeseen fluctuations and short-term load changes in the transmission grid. Energy storage facilities are generally better suited to this task, since they can respond in seconds, unlike the sluggish conventional power plants. All of the offered power must be available within 30 seconds in order to maintain the normal frequency of 50 Hertz and prevent a blackout. Transmission grid operators purchase the primary control reserve they need on a market basis with weekly invitations to bid.
