Stadtwerk Tauberfranken

What Stadtwerk Tauberfranken does

Stadtwerk Tauberfranken GmbH is a regional municipal utility (Stadtwerk) headquartered in Bad Mergentheim, Baden-Württemberg, Germany, serving residential, commercial, and municipal customers across the Tauberfranken and Main-Tauber-Kreis region. It supplies electricity, natural gas, water, district heating (Naturwärme), and fiber-optic broadband, and operates the regulated electricity and gas distribution network as both grid operator (Netzbetreiber) and legally mandated default metering operator (grundzuständiger Messstellenbetreiber) under the EnWG and MsbG. Revenue streams include subscription-based retail supply of all five utilities, regulated network usage fees (Netznutzungsentgelte), metering charges, hardware sales of PV and balcony-PV systems, EV charging and e-carsharing services (via the MOQO platform), and professional energy consulting/contracting services.

The company owns and operates a vertically integrated renewable generation portfolio: a 37.8 MWp ground-mounted solar park (Solarpark Gickelfeld, commissioned January 2024, ~€28M net investment), a 12 MW wind farm (Windpark Külsheim, 5x Nordex N117 turbines operational since 2016), and a biomass combined heat and power plant (Naturwärme Bad Mergentheim, ~8.5 MW thermal wood-chip boiler plus 950 kW_el ORC turbine) feeding an 18.7 km district heating network with 187 connections. A 175 kWp parking-lot PV canopy with 8 EV charging points was commissioned in 2026. Its fiber network has been upgraded to a 10G-capable platform, and the company operates multiple digital self-service portals (Kundenportal, Plusportal for smart meters, Lastgangübersicht for business customers, Internet-Kundenportal) alongside physical customer centers in Bad Mergentheim, Tauberbischofsheim, and Külsheim.

The business model is anchored in regulated network operations and bundled multi-utility supply within a defined concession area, supplemented by direct-to-consumer sales of renewable energy products, EV infrastructure, and consulting. Pricing is individualized through online tariff calculators by postal code, consumption, and household size, and network fees and metering charges are published annually. Go-to-market is direct-to-consumer through online portals and physical customer centers, with dedicated field sales for business and municipal accounts. The company holds at least one wholly-owned subsidiary (Naturwärme Bad Mergentheim GmbH) and minority co-investment stakes in joint renewable projects (Solarpark Gickelfeld 42.1%, Windpark Külsheim) alongside Thüga Erneuerbare Energien, EnBW, and partner municipalities. Managing Director is Paul Gehrig (Dipl.-Betrw. FH); employee count is 101–250.

Broad incumbents

• Stadtwerke München: Largest municipal utility in Germany (Stadtwerk), operating in electricity, gas, district heating, water, and fiber (M-net). Comparable as a vertically integrated municipal multi-utility with strong renewable generation and fiber telecom operations — albeit at vastly larger scale than Stadtwerk Tauberfranken.
• EnBW Energie Baden-Württemberg: Major integrated German utility headquartered in Baden-Württemberg and co-investor with Stadtwerk Tauberfranken in the Gickelfeld solar complex. Comparable as a regional integrated energy player in the same federal state, with overlapping grid, supply, and renewable generation activities.
• E.ON: One of Europe's largest integrated utilities operating distribution networks, retail supply, and distributed energy services across Germany. Comparable as the broad incumbent whose network operations Stadtwerk Tauberfranken interconnects with, and whose regulatory framework (Bundesnetzagentur) governs the company's grid fees.

Direct peers

• Thüga Erneuerbare Energien: Thüga's renewable energy subsidiary and direct JV partner in Solarpark Gickelfeld and Windpark Külsheim. Operates distributed wind, solar, and biomass projects across Germany alongside municipal utility partners — the closest direct peer to Stadtwerk Tauberfranken's renewable generation business.

• Stadtwerke Schwäbisch Hall: Municipal utility in Baden-Württemberg (regional neighbor of Stadtwerk Tauberfranken) supplying electricity, gas, water, heat pumps, fiber broadband, and EV charging. Closely comparable as a mid-sized Baden-Württemberg Stadtwerk with the same multi-utility and digital infrastructure product mix.

Emerging players

• Lichtblick: Hamburg-based green energy retailer and virtual power plant operator offering renewable electricity, heat pumps, and e-mobility products. Comparable as an emerging player in the renewable retail and distributed energy aggregation space intersecting with Stadtwerk Tauberfranken's green supply and EV offerings.
