What AAE Naturstrom does

AAE Naturstrom (legal entity AAE Naturstrom Vertrieb GmbH, previously Alpen Adria Energie) is an Austrian family-owned electricity retailer and small-scale generator founded in 1886, currently in its fifth generation of family management under Geschäftsführer Wilfried Johann Klauss alongside co-managing director Richard Kalcik. Headquartered in Kötschach-Mauthen, Carinthia, with a regional office in Wolkersdorf (Lower Austria), the company supplies 100% certified renewable electricity — sourced from Austrian wind, hydro, and solar generation — to residential, agricultural, commercial, and energy-producer customers across all nine Austrian Bundesländer. Its own generation footprint includes Carinthia's pioneering wind turbine 'Ruth' at Plöckenpass (operational since ~1997), the small hydropower plant at Stockenboi, photovoltaic installations, and the Grünsee eco-reservoir; in December 2025 it deployed Austria's first large-scale battery storage system (ADS-TEC BESS5000, 5 MWh).

The company's commercial proposition is structured around five core tariff products targeting different price-risk preferences: Naturstrom PLUS 26 (Umweltzeichen UZ 46 fixed-price with guarantee through 2026), AAE Natur.spot 2.0 (quarter-hourly EPEX SPOT AT dynamic pricing requiring smart meters), Naturstrom Float 1.4 and Öko Float Business 1.4 (monthly-floating EPEX-indexed tariffs with Lastprofilfaktor 1.2), and Grundversorgung (regulated default supply). Pricing averages approximately €0.10–0.18/kWh plus base fees of €1.80–€5.40/month, with monthly billing cadence and SEPA direct debit. Adjacent revenue streams include EV charging infrastructure (22 kW AC stations at Wolkersdorf with SMATRICS roaming, plus go-e smart-charger integration), a solar hardware partnership with Base-Energy Shop (10% customer discount on Balkonkraftwerke), energy-community services under Austrian regulations, and engineering consulting via AAE Consulting Bau & Planung.

Go-to-market is multi-channel: a self-service online switching portal (portal.aae.at/changeportal), phone and email customer service, in-person consultations at trade fairs and events (HausBau + EnergieSparen Messe Tulln, Lavendelfest Wolkersdorf, Teichklang Festival), and channel partnerships with go-e and TullnEnergie. The company holds the Austrian Umweltzeichen UZ 46 certification continuously since 2003, multiple consecutive Green Brand Austria awards since 2014, the Daphne environmental prize (2014), and in January 2026 was ranked #1 out of 129 Austrian electricity providers in the GLOBAL 2000 & WWF Stromanbieter Check under the designation 'Treiber der Stromzukunft'; per E-Control's May 2024 Preismonitor it was simultaneously the cheapest Austrian electricity provider, with claimed savings up to €700/year for a 3,500 kWh household.

Direct peers

• oekostrom AG: Austrian green electricity retailer headquartered in Vienna selling 100% renewable supply to households and businesses with similar tariff structures. Closest like-for-like competitor within Austria's certified eco-electricity segment.
• Greenpeace Energy eG: German cooperative supplying 100% renewable electricity with similar sustainability-led positioning and rigorous third-party certification. Comparable mission-driven competitor in the certified-green segment.
• NATURSTROM AG: German renewable-energy company supplying certified green electricity to households and businesses while developing own wind/solar generation. Highly comparable vertically-integrated eco-electricity model across the DACH region.
• Lichtblick SE: German green-electricity retailer offering dynamic spot-market tariffs and integrated smart-home/charging products. Closest DACH analog to AAE's Natur.spot 2.0 dynamic pricing model and bundling strategy.

Broad incumbents

• Wien Energie: Municipal utility of the City of Vienna supplying electricity (including green tariffs) and EV charging across Austria. Direct competitive overlap with AAE in green retail and municipal e-mobility partnerships, though from a much broader product/portfolio base.
• EVN (Energieversorgung Niederösterreich): Lower-Austria utility active across electricity, heat, and water including own green-electricity tariffs and renewables generation. Overlaps AAE in residential/business green supply with substantially larger scale.
• Verbund AG: Austria's largest electricity company and dominant hydropower generator, with retail supply across all federal states. Overlaps with AAE in green-electricity retail and renewable generation, with materially greater scale, capital, and brand reach.

Regional players

• Energie Steiermark: Styrian regional utility offering green electricity tariffs, hydro/wind generation, and EV charging—overlapping product set in a different Austrian state. Comparable vertically integrated retail-plus-generation model.
• KELAG (Kärntner Elektrizitäts-Aktiengesellschaft): Carinthian regional utility based in Klagenfurt—the same Austrian state as AAE's Kötschach-Mauthen headquarters. Competes with AAE directly for Carinthian retail customers while operating a much larger generation and grid footprint.
• Salzburg AG: Regional Austrian utility for the Salzburg area selling electricity (including green tariffs) and operating hydro and solar generation. Similar integrated profile serving residential and commercial customers with renewable offerings.
