What stadtwerke gronau does
Stadtwerke Gronau GmbH is a municipal utility company (Stadtwerk) wholly owned by the city of Gronau (Stadt Gronau) in North Rhine-Westphalia, Germany. The company provides electricity, natural gas, water and wastewater, heating solutions, e-mobility charging, fiber optic infrastructure, and operates municipal swimming facilities (indoor and outdoor pools, courses, and a bath shop). It serves approximately 52,000 inhabitants across a roughly 25 km² service area that also includes the surrounding postal codes of Heek, Schöppingen, Metelen, and Legden, and operates a gas distribution network of approximately 470 km. The company has held Grundversorger (basic supplier) status for electricity since July 2018 and serves as the grundzuständiger Messstellenbetreiber (basic metering operator) for Gronau and Epe.
The company's core technology stack consists of physical municipal infrastructure (electricity and gas distribution grids, water and wastewater networks, fiber optic passive infrastructure) layered with digital customer-facing platforms: the GronauEnergie+ smartphone app (iOS/Android), an online self-service portal (portal.stadtwerke-gronau.de), an online bath ticket shop (shop.stadtwerke-gronau.de), and an intelligent metering system (iMSys) infrastructure. Differentiated offerings include the Regionalstrom product — 100% green electricity with at least 35% sourced from renewable plants within 50 km of Gronau, verified via Regionalnachweise from the Umweltbundesamt — and a dynamic electricity tariff whose pricing adjusts every 15 minutes against EPEX SPOT exchange prices. A mobile PV cleaning service (hyCLEANER), housed in a self-contained single-axle trailer with osmosis water treatment, is rented to customers and non-customers.
Stadtwerke Gronau operates a hybrid direct-to-consumer and channel-partner business model. Electricity, gas, water, and heating tariffs are sold directly via online tariff calculator and physical customer center at Laubstiege 19, with revenue from volumetric consumption charges plus base fees. Network operations generate regulated network usage fees and metering service revenue. The fiber optic business is structured as an infrastructure partnership: Stadtwerke Gronau plans, builds, and maintains the passive network while Vodafone (and in commercial areas, NDIX, Deutsche Glasfaser, 1&1 Versatel, Epcan) sells active fiber products to end customers. GroMobile serves as the local retail fiber contact. Ancillary transactional revenue comes from hyCLEANER rentals (€50–€150 per period), energy certificate issuance (€95 base fee), and loyalty-program-linked discounts via the in-app Vorteilswelt program. The company has approximately 160 employees and has been recognized as a kununu Top Company in 2025 and 2026.
