What StWZ Strom does
StWZ Energie AG is a Swiss municipal energy and building technology utility headquartered in Zofingen, Canton Aargau, serving the municipalities of Zofingen and Strengelbach. Founded in 1916 and owned by the Einwohnergemeinde Zofingen, the company operates electricity, natural gas, and water distribution networks under a regulated local concession and acts as the sole grid operator in its catchment. Its portfolio spans core utility supply products (electricity under the ECO, VARIA, and REGIOSTROM brands; natural gas including BIO 30 and BIO 100 biogas-blended products; drinking water) and a building technology services division covering electrical installations, building automation, lighting, heating, plumbing, solar PV systems, storage, and EV charging infrastructure.
The technology backbone includes Smart Metering infrastructure for digital consumption monitoring, an EV charging product line built on Zaptec hardware (Go and Go 2 stations) with proprietary intelligent load management for multi-vehicle sites, online Solar- and Heizungsrechner tools for customer acquisition, and a customer portal (kundenportal.stwz.ch) for self-service account management. Through its partnership with Quickline, StWZ distributes internet, TV, and telephony services, adding telecommunications to its utility vertical stack. The company employs between 101 and 250 staff, runs an apprenticeship program for Elektroinstallateure and Montageelektriker profiles, and maintains a 24-hour emergency service (Pikett-Dienst). Commercial and industrial customers are served via a field-sales Gebäudetechnik division led by named department heads.
StWZ generates revenue through a hybrid model combining recurring subscription utility supply (electricity, gas, water), one-time hardware sales of EV charging stations, usage-based EV charging fees (31 Rappen per kWh), professional services for building technology installations, and partnership-based telecommunications distribution. Pricing across consumer products is publicly disclosed in CHF including 8.1% VAT, while commercial EV charging solutions are quoted on an individual offer basis. Its 24th ordinary Generalversammlung in 2025 confirms a mature governance cadence anchored on its single municipal shareholder, with growth signal most evident in EV charging and solar feed-in tariff activity rather than expansion beyond the concession area.
