What Stadtwerke Waldshut-Tiengen GmbH does

Stadtwerke Waldshut-Tiengen GmbH is a municipal multi-utility company (Stadtwerke) headquartered in Waldshut-Tiengen, Baden-Württemberg, Germany, operating under private limited liability (GmbH) structure and 100% owned by the City of Waldshut-Tiengen. The company serves as the statutory Grundversorger (default energy supplier) for the Waldshut, Tiengen, and Kaitle network area for the 2025-2027 regulatory period. Its core product portfolio spans seven branded divisions: strom:werk (electricity supply, 100% hydropower since April 2011), wasser:werk (drinking water supply to approximately 25,000 residents), wärme:werk (district heating via multiple combined heat and power plants with up to 95% total efficiency), netz:werk (fiber optic broadband up to 1 Gbps), erlebnis:werk (Rhine ferry service, public swimming pools, saunas, river cruises), mobilitäts:werk (EV charging, e-car sharing via my-e-car, truck parking with 70+ spaces), and service:werk (customer service hub). The company holds ISO 50001 energy management certification (since 2013) and VDE TSM technical safety certification.

The underlying technology stack combines physical infrastructure (BHKW plants including Schulzentrum Waldshut at 302 kWel and Schulzentrum Tiengen at 343 kWel, water networks sourced from local groundwater and springs, fiber optic network, electricity distribution grid, and district heating networks) with digital customer-facing systems: a Kundenportal (customer portal) for contract and consumption management, PlusPortal smart meter gateway portal powered by Thüga SmartService, online meter reading submission via QR code, and a tariff calculator. Revenue is generated through a hybrid model: subscription-based recurring revenue from electricity, heating, and fiber tariffs; usage-based revenue from water supply (per cubic meter); and transaction-fee revenue from ferry rides, parking, swimming pools, river cruises, and EV charging. Network operation services (Netznutzungsentgelte) are also charged to other energy suppliers using Stadtwerke infrastructure. The customer base spans residential households (primary), commercial and industrial businesses (primary), public institutions and municipalities, and other energy suppliers (secondary). The company is led by Geschäftsführer Wolfgang Amann, with two Prokuristen (Andreas Rutschmann, Thomas Schilling) and a shareholders' meeting chaired by Mayor Martin Gruner. The firm employs 24 staff and operates across Waldshut-Tiengen, Lauchringen, and Wutöschingen through its Regionalwerk Hochrhein partnership.
