What Energie Thun AG does
Energie Thun AG is a Swiss regional multi-utility (Aktiengesellschaft) wholly owned by the City of Thun, serving the Thun area in the canton of Bern with electricity, natural gas and biogas, district heating, and drinking water. The company traces its operations back to the first municipal electricity plant in Thun in 1896 and was reconstituted as Energie Thun AG in 2001. Reported FY2025 revenue was CHF 107.7 million, with EBITDA of CHF 13.5 million (annual profit CHF 1.8 million) and CHF 21.0 million of investment.
The portfolio spans generation and distribution across all four utility streams. Generation assets include the Aarewerke run-of-river hydroelectric plants (44.6 GWh in 2025), other water-power plants (31.8 GWh), and solar installations (62.4 GWh in 2025), all naturemade star certified. Distribution infrastructure comprises 135 transformer stations, smart metering with 15-minute interval consumption data transmitted hourly to a Head End System, and a district heating network of approximately 14 km sourced from the KVA Thun waste-to-energy plant through a partnership with AVAG Umwelt AG. Water is sourced and treated through shareholder WARET AG (25% springs, 75% groundwater). Customer-facing technology includes an online customer portal with two-factor authentication, eBill integration, and a 24/7 AI chatbot ('Tinu') powered by a RAG system on Microsoft Azure OpenAI.
The business model is direct-to-customer unit pricing across both residential (Privatkunden) and commercial/industrial (Geschäftskunden) segments in Thun, Goldiwil, Schwendibach, Homberg, and surrounding districts. Revenue streams combine volume-based tariffs (electricity Hochtarif/Niedertarif, tiered gas, tiered water consumption) with annual basic/fixed charges (e.g., district heating kW capacity, water meter-size-based basic fee) and ancillary connection and construction-site-power services. Supply is sold through multiple branded electricity products (GRUNDPFUUS, THUNPFUUS, Thuner Solarstrom, Thuner Aarestrom, Blau Strom, Thuner KVA Strom, Grau Strom) and gas/biogas blends, with procurement via Gasverbund Mittelland AG on the European market. No external investors or venture funding are involved; the company is municipally owned and reinvests cash flow into local generation, network expansion, and sustainability programs such as the Ökofonds environmental fund.

Energie Thun AG competitors and assessment
Company assessmentBroad incumbents
- BKW Energie AG: Large Swiss energy provider with generation, distribution, and services across Bern/Canton. Overlaps on regional distribution and renewable generation but operates at national scale across broader service territory.
- Repower AG: Swiss-based energy company with hydroelectric generation, distribution, and trading across Switzerland and Italy. Comparable as a Swiss operator with hydro generation roots and regional distribution, though with cross-border scale.
- Axpo Holding AG: Switzerland's largest producer of renewable energy and major grid operator. Comparable as a vertically integrated Swiss energy provider with hydro generation and distribution, though materially larger and broadly diversified.
Direct peers
- IBC Energie Wasser Chur: Municipal utility for the city of Chur (Graubünden) providing electricity, water, and heating. Closely comparable as a smaller Swiss multi-utility operating in a defined regional service area with similar commodity mix.
- EWL Elektrizitätswerk Liechtenstein: National Liechtenstein utility providing electricity, gas, water, and district heating. Comparable as a regional Alpine multi-utility serving a defined territory with similar product breadth.
- Energie Wasser Bern (ewb): Swiss municipal multi-utility serving the city of Bern with electricity, gas, water, and district heating. Highly comparable across product portfolio (multi-commodity utility), customer segments (residential + commercial), and ownership structure (city-owned).
Others
- Swisspower AG: Swiss alliance of municipal utilities (Energie Thun is a customer of their LEGhub platform). Adjacent rather than competing — provides shared services and platforms that Energie Thun and similar municipal utilities consume.
Regional players
- Elektrizitätswerk Davos (EWD): Municipal utility for Davos providing electricity, district heating, and water. Highly comparable operating model (municipally-owned multi-utility serving a single Swiss Alpine community) though smaller in scale.
- Centralschweizerische Kraftwerke (CKW): Regional Swiss electricity provider serving central Switzerland with generation, distribution, and energy services. Comparable as another Swiss regional multi-utility with renewable generation assets, though in a different geographic region.
- Stadtwerke München: German municipal multi-utility providing electricity, district heating, gas, and water in Bavaria. Comparable business model (city-owned integrated utility with significant district heating), operating in a different national market.
