Electricity and waterworks

What Electricity and waterworks does

ewb (Elektrizitäts- und Wasserwerk der Stadt Buchs) is a municipal utility founded in 1902 and wholly owned by the City of Buchs in the canton of St. Gallen, Switzerland. The company supplies electricity, water, and fiber-optic telecommunications to residential households, SMEs, and large commercial customers across Buchs and the broader Werdenberg region, with a workforce of 51-100 employees. Its energy offering is anchored on 100% renewable sourcing from hydropower, biomass, solar, and wind, and it operates its own hydroelectric plants at Altendorf and Tobeläckerli alongside the Europe-unique Agri-PV Lubera installation (10,700 sqm of greenhouse-integrated Insolight semi-transparent modules producing 750,000 kWh/year).

The business spans four recurring revenue streams: tiered electricity tariffs (ewb Basis Standard for residential, Expert for SMEs, Top/Pro for large customers, plus Kommunal/Baustrom); water supply; FTTH-based telecom services delivered through the Rii Seez Net brand and hosting Swisscom, Sunrise, Salt Mobile, Speedcom, and SAK Digital on its fiber; and solar PV installation services (in partnership with edion AG) bundled with battery storage, EV charging, and Smart Home integration. The ewb Portal provides self-service consumption monitoring, and the physical ewb Shop at Grünaustrasse 29 in Buchs serves as a consultation and retail hub including the Rii Seez Net Competence Center and the ewb Akademie.

Recent strategic activity centers on the 2023 launch of the Agri-PV Lubera project (recognized with the Solarpreis 2024 and Watt d'Or 2025), the March 2025 partnership with SAK to expand fiber into Werdenberg and Sarganserland, the long-term fiber-strand agreements with Swisscom and Sunrise (October 2024), formation of the Powernova regional procurement cooperative in 2025, and the April 2025 appointment of Jürg Göldi as Director. The company continues to roll out FTTH within buildings through 2027 and is launching the LEG (Lokale Elektrizitätsgemeinschaft) local electricity community product in 2026, extending its self-consumption billing portfolio (EVG, vEVG, ZEV, vZEV) into multi-property settings.

Direct peers

• SAK (St.Gallisch-Appenzellische Kraftwerke AG): Cantonal utility group covering St. Gallen and Appenzell regions with electricity, grid, fiber optic, and renewable energy services. ewb partners with SAK for accelerated FTTH deployment in Werdenberg/Sarganserland, making SAK the closest operating peer in scale and portfolio mix.
• Wasser- und Elektrizitätswerk Walenstadt: Multi-utility municipal operator offering combined water and electricity services in the Walenstadt region; member of the Powernova procurement cooperative alongside ewb. Closely comparable in scale, regulated tariff structure, and renewable supply profile.
• St. Galler Stadtwerke (sgsw): Integrated municipal utility of the City of St. Gallen offering electricity, water, telecom, and renewable energy services. Same Swiss Stadtwerk archetype as ewb but at considerably larger scale in the same canton.
• Elektra Gams: Municipal electricity utility for Gams (Werdenberg) and a Powernova partner. Closely comparable in scope (electricity distribution and grid operation) and customer base, but with narrower service portfolio than ewb.
• Elektrizitätswerk Sennwald: Local municipal utility serving Sennwald in the Werdenberg district and a Powernova partner. Very comparable in size and operating model, although narrower than ewb's multi-service platform.
• Technische Betriebe Grabs: Municipal utility for the town of Grabs (Werdenberg), part of the Powernova cooperative. Comparable small-scale integrated utility serving a single municipality with similar geographic and demographic profile to ewb.

Broad incumbents

• BKW Energie AG: Large Swiss energy and infrastructure group providing electricity, services, and networks to commercial and industrial customers nationwide. Competes for larger commercial loads that may otherwise default to ewb's ewb Basis Top/Pro tariffs.
• Repower AG: Vertically integrated Swiss utility active in Graubünden, Eastern Switzerland, and Italy with generation, grid, and end-customer supply. Overlaps with ewb in renewable supply, hydropower, and grid services in the regional market.
• Elektrizitätswerk der Stadt Zürich (ewz): One of Switzerland's largest municipal utilities, owned by the City of Zürich; offers electricity, fiber (ZüriNet), and renewable generation. Useful as the upper-scale benchmark for a multi-service Stadtwerk model, although operating at far larger scale than ewb.
• Axpo Holding AG: Switzerland's largest producer of renewable electricity and a major energy services provider across generation, distribution, and trading. As a cantonal/national-scale incumbent, Axpo competes with ewb for larger commercial and industrial customers in the St. Gallen region.
