What Energie Steiermark does

Energie Steiermark AG is an Austrian integrated multi-utility headquartered in Graz, Styria, wholly owned by the State of Styria (Land Steiermark). The company was formed in 2005 through the merger of STEWEAG and ESTAG and now operates as a holding with six wholly-owned subsidiaries: Energie Steiermark Kunden GmbH (retail customer services), Energie Steiermark Business GmbH (commercial customers), Energie Steiermark Wärme GmbH (district heating), Breitband GmbH (telecom infrastructure), Green Power GmbH (green energy), and E1 Wärme und Energie GmbH (solar energy services). Approximately 2,200 employees serve about 600,000 residential, SME, large-enterprise, agricultural, municipal, and housing-developer customers across 29 sites in Styria, a sales subsidiary in Vienna, and international operations in Slovakia, Czech Republic, Slovenia, Germany, and France.

The company's core operations center on 100% renewable electricity generation (hydroelectric, wind, solar, biomass), natural gas supply, district heating networks across multiple Styrian regions, passive broadband infrastructure, photovoltaic product lines, and electromobility services. Customer-facing brands include SteirerStrom (electricity in Fix, Flex, Spot variants), Erdgas (natural gas), SonnenStrom (PV feed-in tariffs linked to EPEX Spot AT and E-Control reference value), AgrarStrom (agricultural tariffs), and the elinx e-mobility app paired with wallbox hardware. Supporting tools include the Kundenportal self-service platform, energyLIVE/energyUSE energy management platforms, smartCOMMUNITY for energy sharing (Energiegemeinschaft), the PV-Planer online configurator, and the Energiesammler customer loyalty club.

Revenue is generated through seven subscription/recurring streams: electricity supply, natural gas supply, district heating, photovoltaic products and services, electromobility, broadband, and an emerging green hydrogen contract (long-term agreement with Wolfram, 2026-06-19). Go-to-market is hybrid: sales-led with dedicated account management for large enterprises and municipalities (>100,000 kWh/year); product-led via online ordering, PV planner, and the Kundenportal for residential and SMB customers; and channel/distributor-led internationally via subsidiaries and ownership stakes across five countries. Pricing varies by tariff and segment, with feed-in and spot products benchmarked to EPEX Spot AT and E-Control reference market values minus disclosed processing fees.
