What oekostrom AG does

oekostrom AG is an Austrian independent renewable energy provider founded in 1999 from the environmental and anti-nuclear movement, headquartered in Vienna with operating subsidiaries in Slovakia (oekostrom Service s.r.o.) and affiliated entities including MeinAlpenstrom GmbH and oekostrom Handels GmbH. The company supplies 100% renewable electricity sourced from its own wind and solar generation, more than 2,000 customer-owned solar installations, and procurement of additional renewable volumes, complemented by a biogas gas product with voluntary labeling since 2018. Core offerings include fixed and dynamic residential tariffs (oeko Fix, oeko Österreich, oeko Spot+), Grundversorgung mandatory basic supply, e-mobility and balcony power plant products, and B2B services via Key Account Management for large commercial customers. Differentiated technology features include the smartSparen device-control add-on (heat pumps, EVs, wallboxes) delivering up to 25% cost savings via automated load shifting, an in-house Eigenhandelsplattform energy trading platform, and direct marketing (Direktvermarktung) plus flexibility marketing services for renewable producers and storage operators.

The business model is primarily a recurring retail electricity and gas supply subscription, augmented by managed services in direct and flexibility marketing for renewable producers, one-time project development revenue (wind, PV, agri-PV), and a self-managed shareholder platform (aktie.oekostrom.at) where over 3,000 shareholders trade shares internally to fund capital needs without listing. Go-to-market is digital-first DTC for residential and SMB customers via oekostrom.at and the mein.oekostrom.at customer portal, paired with sales-led Key Account Management for enterprises consuming over 100,000 kWh annually. Pricing is publicly disclosed for standard residential tariffs (Grundversorgung: ~15.50 cents/kWh working price ex-VAT for electricity; ~14.50 cents/kWh for gas) with individualized offers for large business. The company maintains its own generation pipeline in Austria, Slovakia, and the Czech Republic, with a 17 MWp agri-PV hybrid plant in Parndorf (Burgenland) under construction in partnership with Green Planet Energy and Stadtwerke Hartberg, plus extensive Slovak solar SPV acquisitions completed between 2022 and 2025 and co-ownership of Czech wind farms in Protivanov and Oldřišov.
