What Electricity Works Jona Rapperswil does

Elektrizitätswerk Jona-Rapperswil AG (EWJR) is a Swiss regional electricity utility founded in 1902, headquartered in Jona (Rapperswil-Jona), operating under a regulated local monopoly for basic energy supply within its defined Versorgungsgebiet. The company generated CHF 53.1 million in FY2025 revenue across the EWJR Group with CHF 4.8 million in annual profit, distributing 172 GWh of electricity and employing 86 staff as of December 31, 2025. EWJR is structured around three divisions: Energie (regulated electricity supply via Grundversorgung and related Stromprodukte), Gebäudetechnik (building technology services including photovoltaics, e-mobility charging, heat pumps, ice storage, battery storage, electrical installation, lighting, automation, and IT/communications), and Netze (grid network services, large-scale battery storage, grid connections, and equipment rental). The company is incorporated as a Swiss Aktiengesellschaft with approximately 1,400 shareholders and shares trading on otc-x.ch at a tax value of CHF 5,200 per share as of December 31, 2025.

EWJR's business model combines regulated recurring subscription revenue from residential and commercial energy supply with project-based professional services revenue from building technology installations and third-party grid services. Pricing on the regulated supply side is set annually with a new seasonal model introduced for 2026 reflecting 12-20% price reductions, while installation services are quote-based. The technology stack is conventional utility infrastructure augmented by smart meter rollout (17,500 units), an in-house customer portal (Kundenportal), a MyEWJR mobile application with the Energie-Assistent consumption monitoring feature, and integration with Zaptec Pro EV charging hardware via the NovaVolt AG partnership. Two wholly-owned subsidiaries, ch-Solar AG and Sustech AG, extend the company into dedicated solar and clean-tech verticals. EWJR holds ISO 9001 and ISO 14001 certifications and is GDPR-compliant.

The customer base is split between a captive residential and SMB Grundversorgung pool in Rapperswil-Jona and a diversified enterprise project portfolio spanning real estate (St. Galler Pensionskasse, Magnolienpark), construction (Künzle Holzbau, Rüegg Karl Tiefbau), education (HSR Rapperswil), retail (ALIGRO), and manufacturing (Helbling & Co. AG). Distribution is direct via the Jona headquarters service counter (Verkaufsschalter), on-site installation crews, the online customer portal, and the MyEWJR app. Marketing channels emphasize regional sponsorship and community engagement. The competitive position rests on a regulated monopoly within the supply area, a 120+ year regional brand, and an integrated one-stop-shop offering spanning energy, installation, and grid services.
