StWZ Strom

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.

Direct peers

• IBAarau AG: Municipal energy utility based in Aarau (neighboring Aargau city to Zofingen) supplying electricity, gas, water, and energy services. Directly comparable in size, governance, and Swiss municipal-utility business model.
• EKZ (Elektrizitätswerke des Kantons Zürich): Cantonal utility serving the Zurich region with electricity, heat, telecom (including Quickline partnership), EV charging (EVolve), and building energy services. Comparable integrated utility model with similar service mix including Quickline telecom.
• AEW Energie AG: Regional energy utility in Aargau providing electricity, gas, water, and energy services to municipalities in the same Swiss canton as StWZ. Most direct comparable — overlapping product portfolio, customer base type (residential + commercial + industrial), and regulated utility model.
• Energie 360°: Zurich-based multi-utility providing natural gas, biogas, heat, electricity, and mobility/EV charging solutions. Closely comparable in biogas/biomethane product focus (Naturwärme, Biogas offerings) and integrated gas-heat-EV service approach.
• EBL (Genossenschaft Elektra Baselland): Swiss multi-utility cooperative offering electricity, natural gas, heat, water, telecom and EV charging solutions. Highly comparable in product breadth, cooperative/regulated governance style, and integrated building energy services positioning.

Regional players

• Primeo Energie: Swiss energy and heat provider based in Münchenstein (Baselland) with renewable heat and electricity products. Already a partner of StWZ for heat services — comparable in biogas/heat product focus and Swiss energy services scope.

Emerging players

• Move (formerly Plug'n Roll): Swiss EV charging network operator owned by Alpiq, providing public and home charging solutions. Comparable in EV charging product line and Swiss market presence, though operates as charging-specialist rather than integrated utility.
• Burkhalter Group: Swiss building technology services provider covering electrical installations, building automation, and energy infrastructure. Directly comparable in Gebäudetechnik/electrical installation services segment StWZ delivers.

Broad incumbents

• BKW AG: Major Swiss energy and infrastructure group with electricity generation, distribution, building technology services, and EV charging (Mobility Solutions). Comparable integrated services but operates at national scale across multiple cantons.
• CKW (Centralschweizerische Kraftwerke): Larger cantonal energy utility in Central Switzerland offering electricity, heat, telecom, and EV charging services. Comparable product portfolio but at larger scale and broader regional reach.
