Stadtwerke Delmenhorst

What Stadtwerke Delmenhorst does

Stadtwerke Delmenhorst GmbH is a municipal utility company (Stadtwerke) founded in 1890 and wholly owned by the city of Delmenhorst in Lower Saxony, Germany. Operating as the parent of the StadtWerkegruppe Delmenhorst, it runs four wholly-owned subsidiaries: Abfallwirtschaft Delmenhorst GmbH (waste management), BAD Bäderbetriebsgesellschaft mbH (GraftTherme leisure facility), Parkhaus Delmenhorst GmbH (city parking garage), and Versorgung und Verkehr Delmenhorst (supply and transport). The group supplies electricity (DelmeStrom), natural gas (DelmeGas), drinking water, and wastewater treatment services to residential, commercial, and 22 large industrial customers within the Delmenhorst concession area, and is designated gas Grundversorger through 2027. Its core infrastructure includes an 801 km gas distribution network across high (68 km), medium (34 km), and low (337 km) pressure tiers, delivering approximately 703,942,339 kWh annually with a peak hourly demand of 256 MW recorded on 18.02.2025.

The product portfolio spans commodity supply (DelmeStrom Natur 100% green electricity, DelmeGas Natur climate-neutral gas with 12-month price guarantee), turnkey heating-transition solutions (DelmeStrom Plus heat pump package with subsidy handling), E-Mobilität including wallbox installation, comprehensive waste collection including the Gelbe Tonne (yellow bin), wastewater treatment upgraded with a €4.5 million NBank-funded fourth treatment stage, public parking, and the GraftTherme swimming and wellness facility. Adjacent municipal services include street lighting and traffic management. Distribution combines a physical presence — headquarters at Fischstraße 32-34, a ServiceCenter at Lange Straße, and operational facilities — with digital channels including the sWapp mobile app (iOS/Android), customer portal at kundenportal.swd-del.de, CAS-authenticated Planauskunft network information portal, and the quarterly customer magazine "nah dran".

Revenue is generated primarily through recurring subscription-based utility charges for electricity, gas, water, wastewater, and waste management, supplemented by transaction-fee revenues from parking operations and GraftTherme admissions. The go-to-market is direct-to-consumer serving residential (Privatkunden) and business (Geschäftskunden) customers in the Delmenhorst region, with third-party gas network access regulated and managed through EVU-Assist GmbH under framework contracts. The company is a member of the ASEW Stadtwerke-Initiative Klimaschutz alongside 43 municipal utilities committed to greenhouse gas neutrality, and has secured federal funding under the Nationale Klimaschutzinitiative (project 67K23041) for wastewater plant emissions reduction feasibility work. With 101-250 employees and 11 distinct training professions, Stadtwerke is one of the largest employers in the region.
