Stadtwirtschaft Weimar

What Stadtwirtschaft Weimar does

Stadtwirtschaft Weimar, operating through its utility subsidiary Stadtwerke Weimar GmbH, is a municipal multi-utility headquartered at Industriestraße 14 in Weimar, Germany, with origins in the 1900 founding of the e-werk. The company supplies electricity, natural gas, district heating (Fernwärme), and E-mobility services to approximately 60,000 residents and businesses in the Weimar region. It also offers photovoltaic consultation and supports customers installing residential PV systems. The product portfolio is structured around multi-variant tariff brands: WeimarStrom (standard, Öko, Online, Wärme, Dynamisch), WeimarGas (standard, Öko, Online), Grüne Fernwärme, and E-Mobilität packages including charging points, Wallbox home hardware, E-auto tariffs, and the 280 EUR THG-Quote premium service. Supporting infrastructure includes an online customer portal, an in-person Kundencenter at Theaterplatz 2a, dedicated business-customer sales (RLM metering, framework contracts across multiple sites), and an active grid and district heating network.

The company is organized as a German GmbH jointly owned by Stadtwirtschaft Weimar GmbH (51% municipal holding) and Thüringer Energie AG (49% regional energy provider), reflecting a public-private municipal utility structure with no public listing or external venture funding. Revenue is generated almost entirely through regulated and competitive retail tariffs on a recurring subscription basis, with ancillary income from EV hardware sales, PV consultation, THG-Quote certification, and basic supply (Grundversorgung) fees. Customer acquisition combines a digital-first self-service motion with on-site consultation at the customer center and outreach across Facebook, Instagram, YouTube, LinkedIn, XING, and a quarterly customer magazine.

The utility is mid-transition into decarbonization. Operating headcount is reported at 101-250, with leadership comprising Constanze Reppin as Geschäftsführerin and Peter Kleine as Aufsichtsratsvorsitzender, supported by managing director Frank Harz and executive director Jörn Otto. Strategic priorities are anchored by a commitment to near-climate-neutral green district heating by 2040 in line with Thüringer Klimagesetz, executed through the 2026 groundbreaking of the Solarthermie-Projekt, deployment of intelligent metering systems, and rollout of dynamic pricing tariffs. Distribution remains geographically confined to Thuringia, with no disclosed expansion beyond the single Weimar service area.
