Stadtwerke Nürtingen GmbH

What Stadtwerke Nürtingen GmbH does

Stadtwerke Nürtingen GmbH is a municipal utility (Stadtwerke) serving the city of Nürtingen in Baden-Württemberg, Germany, and five surrounding districts (Hardt, Neckarhausen, Raidwangen, Reudern, Zizishausen), with the City of Nürtingen as sole shareholder and Jonas Graßhoff as Managing Director (Geschäftsführer). The company supplies electricity, natural gas, drinking water (sourced since 2011 exclusively from Bodenseewasserversorgung / Lake Constance), and district heating across 16 heating networks, and operates as the default supplier (Grundversorger) for electricity and gas in PLZ 72622.

The company operates a vertically integrated physical infrastructure platform: 175 km of water pipeline, 100 km of natural gas network, 160 km of fiber-optic and conduit infrastructure, 11 elevated water reservoirs, 10 combined-heat-and-power (BHKW) units ranging from 5.5 kW to 1,065 kW electrical output, a run-of-river hydroelectric plant on the Neckar, a turbine at Trinkwasserhochbehälter Geigersbühl, and various rooftop photovoltaic installations, producing roughly 9% of total electricity demand from renewable sources. Adjacent infrastructure businesses include the NT-net fiber internet and telecommunications service (up to 1,000 MBit/s), a city-wide LoRaWAN IoT network, approximately 30 public EV charging points, swimming and sauna facilities (Freibad, Hallenbad, Inselbad Zizishausen), and parking operations. Digital channels include iOS/Android mobile apps for meter reading via camera scan, consumption tracking, and a local-partner "Angebotewelt" voucher loyalty program, plus dedicated self-service portals for retail and special-contract customers.

The company generates revenue through recurring subscription tariffs for energy and telecom supply, transactional admission and value-card sales for bathing facilities, one-time and project revenue for heat contracting and wallbox installations, and increasingly through energy-market arbitrage once the 2026 battery-storage joint venture (with ADS-TEC Energy and citizens' cooperative BEGiNT) commissions. Customers are organized across residential (Privatkunden), commercial/industrial (Gewerbe/Industrie) under the TempusProfi tariff, and municipal/public sector (Kommune) segments, with the City of Nürtingen itself serving as the principal municipal customer for schools, public pools, street lighting, and fiber expansion. Headcount stands at approximately 110 employees including apprentices, and the company is privately held as a GmbH with no public capital markets activity or disclosed funding rounds.
