Electric Boiler – Cogeneration Plant Karoline

The electrode boiler located inside an already existing building part of the electric power transformation substation at the Karolinenstraße was replaced due to the expiration of service life of its main components. The aim of the renewal was to replace the existing electrode steam boiler system by a warm water electrode boiler including all ancillaries, transformers, substations and control systems.

In the future the new electrode boiler will be available as a short-term and flexible ready-to-use heat generation system. The Electrode Boiler is mainly used as a peak load heat generator to secure the district heating network during the heating season. Furthermore, the new boiler in its function as a Power-to-Heat-System is going to be part of the German research program SINTEG, to provide heat for the district heating network in case of short-term oversupply of electricity produced by wind turbines in Schleswig-Holstein. In addition, the plant can be operated depending on the electricity prices on the spot market or as a fast and considerable operating reserve for the electricity network.
