Bioenergie Gruppe

What Bioenergie Gruppe does

Bioenergie Gruppe is a family-owned renewable energy operator headquartered in Köflach, Western Styria, Austria. Founded in 1874, the company has specialized in climate-friendly biomass heating for more than 25 years, planning, constructing, and operating a diversified portfolio of renewable energy assets. It serves three principal customer segments: private households, public institutions, and commercial and industrial enterprises, with a primary geographic footprint in Western Styria and additional operations at St. Pölten (hydropower), Rohrbach an der Lafnitz (pellets), and Zeltweg (biogas).

The company's core technology base consists of 32 standardized biomass heating plants connected to district heating networks, supplemented by 4 biomass combined heat and power (CHP) plants generating 9 MW of electrical capacity. Its largest asset, the Köflach II CHP plant commissioned in March 2021, delivers 15 MW of thermal and 3 MW of electrical output while processing approximately 250,000 cubic meters of biomass annually sourced within a 50-kilometer radius. Beyond biomass, the group operates 8.7 MW of wind capacity across the Gaberl I and II wind farms, 590 kW of legacy hydropower, a biogas plant at the Zeltweg military base, and 86 MW of industrial waste heat recovery through five projects, including partnerships with paper mills Heinzel Pulp and Sappi. Subsidiary Steirer Pellets GmbH produces 90,000 tonnes of wood pellets annually at Rohrbach using sawdust from partner rhi Holzindustrie Rubner, avoiding 330,629 tonnes of CO2 emissions in 2025.

Bioenergie Gruppe generates revenue through three primary streams: subscription-based district heating sales to connected end customers, usage-based electricity generation and grid feed-in from its CHP, wind, hydro, and biogas assets, and pellets sales through Steirer Pellets GmbH. The company employs 51-100 people and operates through wholly-owned subsidiaries including Bioenergie Wärmeservice GmbH, Bioenergie Köflach GmbH, and Agroforst – Schaflos GmbH. Its go-to-market is sales-led and project-based, anchored in long-term heat supply contracts with municipalities and industrial partners, while benefiting from Austrian federal, state (Styria), and EU-level subsidies channeled through KPC (Kommunal Kredit Public Consulting). Revenue figures are not publicly disclosed.
