What Stadtwerke MüllheimStaufen GmbH does

Stadtwerke MüllheimStaufen GmbH is a municipal utility company (Stadtwerk) founded on June 18, 2009, headquartered at Marktstraße 1-3 in Müllheim, Baden-Württemberg, Germany. It supplies electricity (100% green/Ökostrom), natural gas, drinking water, and district heating to approximately 28,500 residents in Müllheim, Staufen, and surrounding municipalities, and also provides technical-operations management for water networks in neighboring Auggen, Münstertal, and Sulzburg. The company is owned by the cities of Müllheim (48.9%) and Staufen (26%), with the remaining 25.1% held by a consortium of six other German municipal utilities (KommunalPartner). Two physical customer offices in Müllheim and Staufen, supplemented by phone service, an online tariff calculator, and a customer referral program (€25 reward), form the go-to-market motion.

The company operates electricity, gas, water, and heating infrastructure that it owns but, in the case of electricity and gas networks, leases to naturenergie netze GmbH and Badenova Netze GmbH respectively for operations and maintenance. District heating is delivered through Holzwärme Müllheim GmbH (HWM), a joint venture with Energiedienst Holding AG established in 1996, featuring a ~3,000 kW wood-chip furnace and 6,000 kW of oil boiler peak-load capacity producing roughly 10.5 million kWh annually. Adjacent energy solutions include photovoltaic installations (e.g., on Faust Gymnasium Staufen producing up to 98,000 kWh/year), heat pump sales, and public EV charging stations operated with green electricity.

Revenue is generated through subscription-based recurring utility supply contracts across electricity, gas, water, and district heating, with monthly billing. The company also generates income from energy-solution installations (PV, heat pumps) and e-mobility charging. All surpluses are reinvested into the municipal budgets of Müllheim and Staufen rather than distributed externally, reinforcing the regional value proposition of keeping profits local and supporting community initiatives including sponsorship of local sports clubs, cultural events, and the BEGS citizen energy cooperative initiated in 2012.
