What Stadtwerke Kelheim does

Stadtwerke Kelheim GmbH & Co KG is a municipal multi-utility based in Kelheim, Bavaria, operating across electricity, natural gas, district heating from biomass, drinking water, fiber optic internet, and e-mobility services. The company serves residential and commercial customers in the Kelheim district, including approximately 20 municipalities through the Abens-Donau Energie consortium, with a customer center at Ludwigsplatz 1 in Kelheim city center. It is 65% owned by KELDORADO Bäderbetriebe GmbH (itself 100% owned by the City of Kelheim) and 35% by Thüga Aktiengesellschaft, embedding the utility within a publicly governed municipal structure.

The company's core technical infrastructure centers on a biomass combined heat and power plant commissioned in 2011, with 4,500 kW thermal and 600 kW electric output (via ORC turbine), fed by regionally sourced wood chips and supplemented by a 121 kW peak rooftop PV system. A 200,000-liter thermal buffer storage (Pufferspeicher) was installed at the biomass CHP plant in 2024, generating 62 tonnes of annual CO2 savings through load balancing. Additional infrastructure includes a fiber optic network under expansion since 2018, a roll-out of intelligent metering systems (intelligente Messsysteme), and a digital Netzanschlussportal launched in 2024 for network connection management. The company holds DVGW, AGFW, and VDE Technical Safety Management (TSM) certifications across electricity, gas, water, and district heating, alongside ISO 50001 energy management certification and IT-Sicherheitskatalog certification from the Bundesnetzagentur.

Stadtwerke Kelheim generates revenue primarily through recurring subscription tariffs across its utility product lines (Haushaltsstrom, Wärmestrom, Mobilstrom, Dynamischer Stromtarif for electricity; Haushaltserdgas for gas; Biowärme for district heating; Trinkwasser for water; Glasfasertarife for fiber internet), plus transactional e-mobility revenue from charging solutions, charging card access, and E-Carsharing. Network operation services (Netzbetrieb) and energy consulting/building certification services round out the revenue mix. Distribution combines direct sales through the city-center customer center and field service Tiefbau-Team with self-service digital channels including the customer portal and network portal. The company is part of a broader cooperative ecosystem via minority stakes in Thüga-affiliated entities (Plattform Energie for joint procurement, VISCONTO for shared IT services, KOM9 for municipal utility advocacy) and operational joint ventures (Regioladen+ for charging infrastructure, Abens-Donau Energie for regional hydropower-based supply, BürgerEnergie Niederbayern eG for citizen energy participation).
