EXAA - Energy Exchange Austria

EXAA (Abwicklungsstelle für Energieprodukte AG) is Austria’s power and environmental exchange based in Vienna. Founded on 8 June 2001, EXAA started operating spot market trading in electricity on 21 March 2002. Ever since, EXAA has been instrumental in developing efficient trading in the liberalised energy markets of Central Europe.

In addition to the standard tasks relating to exchange trading, EXAA is directly responsible for the settlement of financial transactions (clearing) and assumes the counterparty risk for all executed trades.


In December 2012, EXAA was the first European energy exchange to launch an additional market for the trading of power exclusively from renewable hydro and wind energy resources.

The concept offers the opportunity for exchange trading of green power and integrates well with the existing day-ahead spot market. It offers a trading platform which is independent of the feed-in tariffs defined by the German “EEG” and the Austrian “Ökostromgesetz”. It combines the best elements of bilateral trading based on guarantees of origin and those of exchange-based electricity trading coupled with physical delivery.

EXAA in a nutshell:

  • First energy exchange in Europe to launch green power trading.
  • Daily spot auction.
  • Proof that EXAA’s GreenPower exclusively originates from renewable energy sources, verified by the well-established European Guarantee of Origin (GO) standard – EECS.
  • Pool of regularly published and updated supplier facilities.


teem (training for energy and environmental markets)

EXAA offers teem as a compact training course for electricity and gas markets. Experienced energy experts cover main energy topics ranging from energy markets, energy law and energy technology. The courses are aimed at energy newcomers as well as experienced employees who seek to broaden and update their knowledge. Teem is a market leader in energy market training, provides up-to-date and concise content and offers excellent value for money. Delegates especially appreciate the modular design, allowing all modules to be booked individually.
