EW Sirnach

What EW Sirnach does

EW Sirnach AG is a Swiss municipal utility company headquartered in Sirnach, Thurgau, that serves approximately 8,000 residents with integrated electricity, water, and fiber-to-the-home (FTTH) communication services. Founded as a municipal utility (Gemeindewerk) in 1922 and converted to a stock corporation (Aktiengesellschaft) in 2002, the company operates as a regulated regional utility with municipal assembly governance and inherent monopoly rights in its service territory. The company employs around 45 staff across field operations, network construction, electrical installations, and customer service, maintaining a branch office in Bettwiesen (since 1953) in addition to its headquarters. FY2025 capital investments were CHF 910,000 in the electricity network, CHF 580,000 in water infrastructure, and CHF 590,000 in FTTH expansion, reflecting continuous infrastructure renewal within a stable customer base.

The company's core offering comprises three utility networks plus a growing portfolio of value-added services. Electricity supply is delivered through tiered products co-developed via the Thurgie AG consortium with neighboring regional utilities—THURGIE Blau (standard 100% renewable), THURGIE Grün (premium naturemade-certified renewable), and THURGIE Grau (budget non-renewable)—priced by annual consumption volume tiers (Basis, KMU, Industry). Water supply and FTTH communications complete the core utility stack. Beyond basic supply, EW Sirnach operates an adjacent services platform including building automation through Loxone Gold Partner status, E-mobility charging via the MOVE/energie360° network, photovoltaic installations, self-consumption community administration (ZEV, vZEV, LEG, EVG/vEVG models), and AI-assisted energy management through the EFFECTAS platform. Product launches in vZEV (January 2025) and LEG (January 2026) align the company with Switzerland's revised electricity law and decentralized energy market structure.

Revenue is generated primarily through usage-based electricity and water tariffs with monthly billing, supplemented by recurring subscription fees for EVG/vEVG community administration and the MOVE Comfort charging subscription (CHF 59/year). FY2025 operating revenue reached CHF 22,907,120.74 with operating profit of CHF 596,831.63, reflecting typical municipal utility economics. The go-to-market motion is sales-led but operationally direct: company-owned field teams deliver installations and maintenance, the headquarters and Bettwiesen branch serve as customer-facing offices, and a digital customer portal enables self-service for consumption monitoring, invoices, and contract management. Distribution is entirely domestic within the Sirnach municipality area.
