Stadtwerke Schwerin are able to use unused energy in a sensible way on the premises of the Schwerin-South thermal power station. Thanks to strong support from SAG Erwin Peters.


Key Facts

  • Kunde: Stadtwerke Schwerin
  • Anlage: Secondary energy balancing system/ Thermal power station Schwerin
  • Commissioned: 2013

SAG Erwin Peters successfully realised the connection of Stadtwerke Schwerin's new 3x5 MW boiler plant to the balancing energy market. The boiler plant makes available up to 10 MW negative secondary balancing power (SBP). Excess electricity is hereby taken from the grid and converted into heat. This is then either stored directly in the heating network or in a heat accumulator.

SAG Erwin Peters realised the redundant coupling in accordance with IEC60870-5-101, the complex cooperative control of the boiler plant with its numerous modes and the necessary control system. Special gateways were used for the telecontrol, a Siemens control system was used for the control, and Proficy HMI/SCADA - iFIX 5.5 was used as the process control system.
