Technische Werke Schussental

What Technische Werke Schussental does

Technische Werke Schussental (TWS) is a German municipal multi-utility jointly owned by the cities of Ravensburg and Weingarten, formed in 2001 from the merger of their predecessor Stadtwerke. The company is headquartered in Ravensburg and operates as a vertically integrated provider of electricity, gas, water, and district heating within its concession area, supplemented by a growing portfolio of e-mobility and digital services including 143 EV charging points, e-carsharing, e-bike rental, the on-demand bus service MOBI, and the twsMobil mobility app.

The core revenue model combines regulated network charges and retail energy margins on electricity, gas, and water with infrastructure fees for district heating connections and operational fees for tenant electricity (Mieterstrom), PV leasing (twsEnergiedach), and submetering/billing services. The e-mobility and shared-mobility lines (twsEcarsharing, twsRad, MOBI) and the commercial deployment of charging infrastructure for fleet operators such as RVV diversify the revenue base beyond traditional utility retail. TWS also pursues municipal partnerships outside the home concession — notably a municipal PV contract with the City of Bad Wurzach — signaling intent to commercialize its renewable and multi-utility capabilities regionally.

Operationally, TWS runs 100+ district heating systems including the largest heat network in Ravensburg's city center, is constructing a new district heating network in Weingarten, and is exploring deep geothermal (Tiefengeothermie) to expand its low-carbon heat supply. The company employs between 251 and 500 staff, operates three customer centers (Ravensburg, Weingarten, Bad Waldsee), and serves both residential/SMB customers and named commercial accounts including Vetter Pharma, Hymer, Reisch, Ebra, HKPE/teba, and RVV. AI use is presently confined to a customer-service chatbot ("Willy"), with no disclosed proprietary models or data-driven optimization of grid or asset operations.

Revenue model

1. Energy Supply (Electricity & Gas): TWS generates revenue by supplying eco-certified electricity (twsÖkostrom) and eco-gas ((Öko)Gas) to residential, commercial, and municipal customers in the Schussental region. Revenue is derived from per-kWh consumption charges and fixed base fees. A dynamic electricity tariff is also offered for flexible pricing.
2. District Heating (Fernwärme): Revenue from providing centralized heating supply to connected buildings via underground district heating networks. Customers pay connection fees and recurring heat supply charges. TWS operates the largest district heating network in the Schussental area, including the Ravensburg city center expansion.
3. Water Supply: Revenue from supplying drinking water to residential and commercial customers in Ravensburg and Weingarten. Part of the regulated utility portfolio.
4. PV Lease / Pachtmodell (Energiedach): TWS generates recurring revenue by leasing PV systems to customers (commercial, municipal, and residential). TWS owns and operates the systems; customers pay a monthly fee and receive green electricity. The 18-year lease model provides long-term recurring revenue.
5. E-Mobility Services: Revenue from operating public EV charging infrastructure (AC and DC fast chargers) and e-carsharing services (twsEcarsharing via Hop-On). Charging revenue is usage-based per kWh; e-carsharing follows hourly/daily rental tariffs.
6. Heat and Operating Cost Billing (Heiz- und Betriebskostenabrechnung): TWS provides submetering and billing services for heat and operating costs to housing companies and landlords. Using radio-based metering technology, TWS reads consumption data, generates legally compliant cost allocations, and creates monthly in-year consumption information (uVI) per the 2022 Heating Cost Ordinance.
