IB Langenthal

What IB Langenthal does

IB Langenthal AG (IBL) is a 100% municipally-owned regional multi-utility headquartered in Langenthal, Canton of Bern, Switzerland, founded in 1894 and operating under the Stadtwerke model of municipal energy provision. The company supplies electricity, natural gas, drinking water, district heating (Fernwärme), telecommunications, and e-mobility charging infrastructure to private households, businesses, real estate operators, and municipalities across the Oberaargau region. Its district heating portfolio comprises three active projects — Wärmeverbund Hard and Nord (wood-chip based) and Wärmeverbund Mitte, the largest infrastructure project in company history now in execution — supported by smart metering across electricity, gas, and water, and a new fiber-to-the-home (FTTH) network developed in cooperation with Swisscom.

The business model is anchored in regulated, subscription-style recurring revenue from commodity supply and network tariffs, complemented by professional services in energy consulting, electrical installation, PV contracting, and ZEV/LEG (energy community) management. IBL combines direct customer service at its headquarters and field-based energy consulting for enterprise and municipal accounts with a self-service online Energieportal for households. Pricing varies by segment and consumption profile; disclosed FY2026 changes include a 10–15% electricity price reduction, a 10–12% gas price cut (from October 2025), and a 23.8% water price increase (from January 2026).

Strategically, IBL is executing a multi-decade energy transition: together with the Stadt Langenthal council it has committed to a full gas supply exit by 2040, redirecting investment into district heating, renewable integration, and e-mobility. The FY2025 result was CHF 80 million revenue with CHF 2.4 million net profit, alongside CHF 14.5 million of net infrastructure investment, signaling a stable, investment-led utility that funds its transition out of operating cash flow rather than external capital.
