Stadtwerke Weinstadt

What Stadtwerke Weinstadt does

Stadtwerke Weinstadt is a municipal utility company (Eigenbetrieb) wholly owned by the city of Weinstadt in Baden-Württemberg, Germany. The company supplies electricity, natural gas (with optional 10% biogas blend), drinking water, and district heating (Nahwärme) to residential and commercial customers within the municipality, and additionally operates an indoor swimming pool (Hallenbad), e-mobility charging infrastructure with THG quota trading, and a fiber optic (Glasfaser) rollout program.

The core technical platform combines physical utility infrastructure — district heating networks powered by high-efficiency BHKW combined heat and power units, 14 elevated water tanks with over 10,000 m³ storage capacity, spring-fed and association-supplied water sources totaling ~1.2 million m³ annually, and a LoRaWAN-based remotely readable water meter rollout — with a digital self-service customer portal for contract management and a dynamic electricity tariff that passes through hourly wholesale market prices. The product portfolio spans 100% hydropower electricity (Ökostrom), standard and Bio10 biogas tariffs, Mieterstrom tenant electricity from on-site solar/BHKW generation, and customer loyalty programs (WeinstadtCARD, Treuebonus, Kunden werben Kunden, Baby-Bonus).

Revenue is generated primarily through recurring subscription-based utility supply contracts and consumption-based water fees, with secondary transaction-based revenue from EV charging fees and Hallenbad entry fees. Pricing for electricity and gas is not publicly disclosed due to wholesale market volatility, while water fees are regulated and transparent (€5.93/m³ total effective January 2025). The company employs approximately 9 people and reinvests profits locally into infrastructure and the city of Weinstadt's climate-neutrality-by-2035 target. Go-to-market combines online self-service ordering via price calculators, inside sales through phone/email, in-person service at the Schorndorfer Straße 22 headquarters, and a 24/7 emergency Notdienst hotline.

Broad incumbents

• EnBW: One of Germany's four large integrated energy utilities and the dominant retail/incumbent supplier in Baden-Württemberg. Competes with Stadtwerke Weinstadt for electricity and gas customers while also providing the backup Stördienst for incidents.
• Netze BW: Distribution system operator for electricity and gas across much of Baden-Württemberg and the regulated infrastructure partner for Stadtwerke Weinstadt's grid incidents (24/7 Stördienst). Operates the same energy delivery infrastructure Stadtwerke Weinstadt relies on.
• Stadtwerke München: Germany's largest municipal multi-utility (electricity, gas, district heating, U-Bahn, Trinkwasser, Telekommunikation). Demonstrates the strategic ceiling of the municipal Stadtwerk model that smaller utilities like Weinstadt operate within.
• Glasfaser Weinstadt / Deutsche Glasfaser: Deutsche Glasfaser is one of the largest FTTH builders in Germany and the natural reference point for the Glasfaser Weinstadt FTTH project the utility is running. Comparable as a broadband infrastructure peer for the fiber-optic arm of Stadtwerke Weinstadt's business.
• Stadtwerke Stuttgart: Large municipal multi-utility for the city of Stuttgart. Same German Stadtwerk model (electricity, gas, water, district heating, swimming pools, mobility) but at much greater scale, providing a benchmark for the upper end of the Stadtwerk value chain.

Direct peers

• Stadtwerke Remseck: Stadtwerk for Remseck am Neckar, another similarly sized Rems-region municipality. Provides electricity, gas, water, and local services to a small-town population, making the operating profile highly comparable to Weinstadt.
• Stadtwerke Fellbach: Municipal utility serving Fellbach, a comparable-size Baden-Württemberg town directly adjacent to the Stuttgart metro. Offers electricity, gas, water, heat, and e-mobility services — a near-twin operating model to Stadtwerke Weinstadt.
• Stadtwerke Schorndorf: Neighboring municipal utility (Stadtwerk) for the city of Schorndorf, just a few km from Weinstadt in the Rems valley. Operates electricity, gas, water, and district heating for a similarly sized municipality, making it the closest comparable German multi-utility peer.

Others

• Landeswasserversorgung: State-level long-distance drinking water supplier providing the majority (~66%) of Weinstadt's water. Closest functional comparability for the water supply side of Stadtwerke Weinstadt's business.

Emerging players

• Remstal Bürgerenergie eG: Local citizens' energy cooperative in the Rems valley and co-investment partner with Stadtwerke Weinstadt in the Solarpark Schönbühl solar park. Compares as an emerging player in the same local renewable generation space.
