Stadtwerke Judenburg

What Stadtwerke Judenburg does

Stadtwerke Judenburg AG is a privately held municipal utility (Aktiengesellschaft) headquartered in Judenburg, Styria, Austria, founded in July 1904. It operates as the designated grid operator and multi-utility provider for the Murtal region, serving more than 60,000 residents and approximately 1,800 businesses across 460 km² and eight municipalities (Judenburg, Fohnsdorf, Pöls, Pölstal, Obdach, St. Peter/Judenburg, Oberzeiring, and Weißkirchen). The company is wholly owned by the municipality/city of Judenburg and regulated by E-Control; it employs approximately 150 people.

The company's operations span eight core service lines: electricity supply (generated from own hydroelectric and photovoltaic assets, fed into a regulated distribution grid), water supply, wastewater treatment (2.3 million liters daily), waste collection, district heating sourced from industrial waste heat, cable TV and fiber internet (under the AINET brand via subsidiary AiNet Telekommunikations-, Netzwerk- und Betriebs GmbH), electrician and HVAC installation services, and funeral services. Approximately 1,600 local energy producers, including 1,550 photovoltaic installations, feed electricity into the company's grid, supported by Smart Meter infrastructure with quarter-hourly readings and a customer web portal.

Revenue is generated primarily through recurring subscription tariffs — regulated network fees (Systemnutzungsentgelte) set by E-Control, electricity supply tariffs across residential/commercial/agricultural segments (with feed-in and SNAP summer-time-of-use tariffs), water/wastewater rates, waste collection fees, district heating charges, and AINET telecom subscriptions — supplemented by professional service revenue from installation, PV system checks, battery storage sales, and funeral services. Go-to-market is direct-to-consumer via the company's own offices, customer portals, 24/7 hotline, in-house installation workforce, and a community-engagement marketing program including events ('Langer Tag der Energie'), a customer magazine ('Fair Informiert'), and paid social campaigns on Meta and TikTok. The company is currently constructing the €45 million Stadtkraftwerk Judenburg, a 5.7 MW run-of-river hydroelectric plant that will replace three historic power plants and nearly double annual generation to 27.3 GWh.
