What Municipal works Gundelfingen does

Gemeindewerke Gundelfingen GmbH (GWG) is a municipal utility (Stadtwerke) owned by the municipality of Gundelfingen in Baden-W\u00fcrttemberg, Germany, providing electricity, natural gas, drinking water, and district heating to approximately 12,000 residents of Gundelfingen and Wildtal, plus electricity and gas customers across the broader S\u00fcdbaden region. The company was formally incorporated in 2013 (HRB 6734) but traces operating history in district heating back to 1990; its managing director is Sebastian Giesel. GWG holds regulated monopoly positions as the local grid operator and basic supplier within its concession area and operates as the parent-affiliated operator of district heating networks owned by GWH (Gundelfinger W\u00e4rmeversorgungs- und Hallenbad GmbH), serving 89 connected buildings through CHP and gas-fired boiler plants.

GWG's technical infrastructure spans electricity and gas distribution networks, two district heating networks (~2.9 km total) with a 230 kW thermal CHP unit producing 425 MWh/year, drinking water supply from local springs and Rheinebene sources, public EV charging stations (7 \u00d7 22 kW across three sites) integrated into the Ladenetz.de roaming network, and digital self-service platforms including an SAP UI5-based Kundenportal and a Netzanschlussportal for installers and developers. All electricity supplied has been 100% renewable since 2015, and a dynamic tariff (Gundelfinger Umweltstrom dynamisch) is linked to hourly EPEX Spot Day-Ahead prices for customers with smart meters.

GWG generates revenue through regulated network charges and metering fees, plus retail tariffs for electricity, gas, water, and district heating billed on subscription/usage bases, EV charging fees (45 Ct/kWh via Ladeapp), and optional Klima-Cent surcharges funding local climate projects. Distribution is direct to consumers via the company website, online tariff calculators, the Kundenportal, a physical customer service office at Sonne-Platz, and direct sales for commercial/mid-market customers. The 23-person team operates the full utility stack across a compact concession area, with Thuega affiliation providing shared municipal-utility resources.

Revenue model

1. Electricity Supply (Strom): GWG supplies electricity to residential and commercial customers in Gundelfingen and surrounding communities (Südbaden). Revenue is generated through base tariffs (Gundelfinger Umweltstrom) with optional Klima-Cent surcharge (1 cent/kWh net) for local climate projects, and a dynamic tariff tied to EPEX Spot prices. Revenue is recurring from residential and commercial customers.
2. Natural Gas Supply (Erdgas): GWG supplies natural gas to customers for heating. Includes products such as ErdgasFix. Revenue is recurring based on consumption (kWh). All gas tariffs are subject to CO2 pricing under the BEHG (Brennstoffemissionshandelsgesetz).
3. Water Supply (Wasserversorgung): GWG supplies drinking water (a mix of local spring water and water from the Rheinebene) to customers in Gundelfingen. Revenue is generated through consumption-based water prices (per m³) and annual base/meter fees by meter size. Water supply is a regulated, recurring revenue stream.
4. District Heating (Fernwärme): GWG operates district heating networks in the Ortsmitte (since 1990) and Nägelesee (since 1996) areas, supplying heat for space heating and domestic hot water to 89 connected buildings. Revenue is generated through base/performance fees and consumption-based heat prices (per kWh), billed annually.
5. EV Charging (E-Mobilität): GWG operates public EV charging stations in Gundelfingen. Revenue is generated through charging fees: 45 Ct/kWh via Ladeapp (ad-hoc), with reduced rates for account customers via the gwg Ladekarte and the Ladenetz.de roaming network.
6. Network Operation and Metering Services (Netze / MSB / MDL): As the local grid operator (Netzbetreiber) for electricity and gas, GWG operates the distribution networks and provides metered services (Messstellenbetrieb / MSB, Messdienstleistung / MDL) in its network area.
