Stadtwerke Muehlhausen

What Stadtwerke Muehlhausen does

Stadtwerke Mühlhausen GmbH is a German municipal utility (Stadtwerke) headquartered at Windeberger Landstraße 73, 99974 Mühlhausen, Thuringia. The company supplies electricity, natural gas, district heating, and DSL broadband internet to residential and business customers within the city of Mühlhausen and surrounding districts (Windeberg, Saalfeld, Görmar, Felchta, Schröterode, and Weidensee), and also performs commercial billing and account-management services for two regional public water and wastewater associations (Zweckverband Trinkwasserversorgung Mühlhausen und Unstruttal and Zweckverband Abwasserentsorgung Mühlhausen und Umland). Electricity is marketed under the MühlStrom brand (with a MÜHLSTROM MOBIL e-mobility sub-line), natural gas under MühlGas, heating under Fernwärme and the City Wärme+ concept (including renewable options such as solar thermal and biomass), and broadband via a 2015 cooperation with Thüringer Netkom for fiber network deployment.

The company's core technology footprint consists of municipal utility infrastructure — generation and distribution assets for electricity, gas, and district heating (including the Sonnenfeld am Schadeberg solar thermal park and a biomass heating plant inaugurated November 2025), a spun-off network operator (Stadtwerke Mühlhausen Netz GmbH, established 2006), and a wind energy joint venture (Windkraft Thüringen GmbH, joined 2013). It holds DVGW and VDE Technical Safety Management (TSM) certification and is licensed for Grundversorgung and Ersatzversorgung within its territory. Distribution occurs through a physical customer service office, an online customer portal, a mobile app, social media (Facebook, Instagram), a customer magazine ('Gute Bekannte'), and press releases.

Revenue is generated via recurring subscription tariffs for electricity, gas, district heating, and DSL services, supplemented by fees from cooperative billing services for the water/wastewater Zweckverbände. Ownership is mixed: Wirtschaftsbetriebe Mühlhausen GmbH holds a 51.0% majority stake, with CONTIGAS Deutsche Energie-AG (25.1%) and TEAG Thüringer Energie AG (23.9%) as minority shareholders, giving the City of Mühlhausen effective control through its municipal holding company. Recent strategic emphasis has been on renewable heat (biomass and solar thermal), digital infrastructure (fiber and customer-facing app/portal), and e-mobility, alongside a leadership transition with Commercial Managing Director Regine Gierse departing in June 2026.
