Stadtwerke Tübingen GmbH

What Stadtwerke Tübingen GmbH does

Stadtwerke Tübingen GmbH (branded as swt) is a municipally-owned multi-utility company headquartered at Eisenhutstraße 6, Tübingen, Germany, founded in 1950 and owned by the City of Tübingen. The company operates an integrated portfolio across electricity (TüStrom, including TÜV Nord-certified Ökostrom), natural gas (TüGas), district heating (TüWärme, leveraging renewable heat from the municipal wastewater treatment plant), drinking water, fiber-optic telecommunications (TüNet FTTH/FTTD), public transport (TüBus), e-mobility (voltap fast charging, ecowerk-echarge), parking (5 garages), and public swimming/recreational facilities (5 venues). It runs over 220 transformer stations and a portfolio of wind and solar generation assets, including the Traufwiesen solar park (June 2024), which supplies over 2,000 four-person households.

Its business model combines recurring subscription revenue across energy, water, heating, and telecom tariffs with transaction-based revenue from parking and swimming facilities, plus managed-services revenue from network operations (connections, smart meter operation, grid maintenance). Go-to-market operates on two tracks: a direct-to-consumer channel via an online customer center (kundencenter.swtue.de) and a physical swt-Kundenzentrum, and a dedicated business customer division (Geschäftskunden) serving commercial, industrial, and rail-power clients. Pricing is quote-based with an online tariff calculator for residential electricity and gas, and three district-heating tiers (Basis, Komfort, Komfort+).

The company is certified under ISO 14001, ISO 50001, TSM (VDE), PÜG, ISMS, and TÜV Nord Ökostrom, has held Top-Lokalversorger recognition for 15 consecutive years (through 2026), and is family-friendly certified since 2013. It serves residential, business, telecommunications, and municipal customers primarily within the Tübingen concession area, with extensions into Dettenhausen, supported by an employee base of 251–500.
