Core offering

Städtische Werke Energie + Wärme GmbH (EWG) is a municipal energy company in Kassel, Germany, that generates and supplies electricity and district heating (Fernwärme) to residential, commercial, industrial, and municipal customers through a 207-km pipeline network fed by combined heat and power (CHP) plants, a waste-to-energy facility, peak-load heating plants, and a run-of-river hydropower station. The company is transitioning to CO2-neutral fuels (sewage sludge and waste wood) by 2025 and also operates an accredited central laboratory (Zentrallabor Kassel) for water and substance analysis.

Product overview

Städtische Werke Energie + Wärme GmbH operates a portfolio of district heating (Fernwärme) and power generation infrastructure for the city of Kassel, Germany. The core offering is the 207-kilometer Fernwärmenetz Kassel district heating network, which distributes heat generated from three main generation sites — the Fernwärmekraftwerk Kassel (FKK) and Kombi-Heizkraftwerk at Dennhäuser Straße, and the Müllheizkraftwerk Kassel (MHKW) — supplemented by three peak-load heating plants (Heizwerke Brückenhof, Losse, Mittelfeld) and the Laufwasserkraftwerk Neue Mühle for hydroelectric generation. The company also operates the Zentrallabor Kassel for water and substance analysis. Expansion projects include new energy zones (Lindenberg, Mattenberg) and the new Fernwärme Kompetenzcenter Fiedlerstraße. The portfolio is undergoing a coal phase-out by 2025, transitioning to CO2-neutral fuels (sewage sludge and waste wood).

Together with the grid and distribution division of Städtische Werke, mobility provider KVG, and telecommunications company Netcom, the group realizes the energy transition by understanding the areas of heat, electricity, and mobility as a whole. EWG participates in KVV's 'Fit für die Zukunft' (Fit for the Future) strategic process.
• Städtische Werke AGcoreStrategic or Co-development PartnerEWG is a subsidiary of Städtische Werke AG. Städtische Werke AG manages customer relationships for district heating, while EWG builds and operates generation facilities and the district heating network. Both companies collaborate on energy supply to Kassel.
• Städtische Werke Netz + Service GmbHcoreTechnology or IntegrationElectricity generated at EWG's plants is fed into the grid operated by Städtische Werke Netz + Service GmbH. The run-of-river hydropower plant at Neue Mühle is operated by Städtische Werke Netz + Service GmbH.
• Müllheizkraftwerk Kassel GmbHcoreTechnology or IntegrationThe Müllheizkraftwerk (waste-to-energy plant) is a separate company (Müllheizkraftwerk Kassel GmbH) but integrated into EWG's operations. EWG's Heizwerk Losse and Heizwerk Brückenhof are operated from the Müllheizkraftwerk's control room. The plant generates approximately one-third of Kassel's district heating via CHP.
• Stadt Kassel (City of Kassel)coreStrategic or Co-development PartnerThe City of Kassel, represented by Oberbürgermeister Sven Schoeller and Christian Geselle, works in close partnership ('Schulterschluss') with EWG on municipal heat planning. The EWG Transformation Plan directly feeds into the city's legally required municipal heat planning (kommunale Wärmeplanung).
• Gemeinnützige Wohnungsbaugesellschaft der Stadt Kassel (GWG)coreStrategic or Co-development PartnerGWG is a key customer and partner in district heating expansion. Its properties in the Lindenberg area and Mattenberg settlement are being connected to the district heating network. GWG has provided concrete orders and letters of intent for district heating connections.
