Stadtwerke Wertheim

What Stadtwerke Wertheim does

Stadtwerke Wertheim GmbH is a municipal utility company (Stadtwerke) headquartered in Wertheim, Baden-Württemberg, Germany, wholly owned by the City of Wertheim (Stadt Wertheim) and chaired by Oberbürgermeister Markus Herrera Torrez, with Thomas Beier as sole managing director. Founded in 1983, the company supplies electricity, natural gas, drinking water, district heating, and fiber optic internet to residential, commercial, and industrial customers across the Wertheim, Kreuzwertheim, and Freudenberg service areas spanning approximately 193 km², and operates the regulated electricity distribution network across the same territory after taking over the Freudenberg grid in September 2024.

The company operates an extensive physical network comprising approximately 689 km of power lines (covering overhead and cable at medium and low voltage), 200 km of gas pipelines (34 km high-pressure, 107.3 km medium-pressure, 58.7 km low-pressure), 80 MVA of installed transformer capacity, a district heating network serving roughly 3,500 residents in Wartberg and Reinhardshof, and a continuously expanding fiber optic network across approximately 27 km². Digital infrastructure includes the GIPS platform for network administration and customer management (delivered by Hehner Reus Systems GmbH), the KIVBF-backed Kunden-Onlineportal for self-service, epilot.cloud for journey-based online service workflows, smart metering with §14a EnWG-compliant controllable load management for heat pumps and wallboxes above 4.2 kW, and SAP-based EDI under GPKE and GeLi Gas standards for market communication with third-party suppliers.

Revenue is generated through regulated network charges (electricity and gas, published annually for 2024-2026), retail supply contracts (electricity, gas, water, district heating), fiber optic subscription services, e-mobility solutions (public charging stations including the first Schnelllader at Bahnhofstraße, wallbox solutions, THG quota trading, and carsharing), PV advisory and feed-in management via the SE SOLAR partnership, heat contracting, house connections, meter operations under §3 MsbG, and citizen participation investment programs such as PowerInvest Almosenberg (€2M target, 4.00% p.a. for customers over 5-year terms). Distribution combines a physical customer center in Wertheim's old town (Rathausgasse 9), field service teams, dedicated key account management for commercial customers, digital channels (website, customer portal, epilot-based online services), and community-based citizen investment offerings. Headcount is in the 51-100 range and revenue is not publicly disclosed.
