The story

EXAA was officially founded on June 8, 2001. The complete liberalization of the Austrian electricity market on October 1, 2001 created the legal framework for the establishment of an electricity exchange. Spot trading at EXAA began on March 21, 2002 for individual hours in the APG control area, with a total of twelve market participants. EXAA spot trading now comprises around 65 electricity trading companies from more than 10 countries, whereby the non-Austrian share of companies currently dominates.

Products and brands

An exchange is an organized trading venue whose processes are subject to legal regulations. The main objective of operating an electronic trading platform with an auction system is to optimize the bundling of liquidity. In addition, the efficiency of trading activities is promoted by significantly reducing the effort involved in concluding transactions compared to bilateral trading. The neutrality of an energy exchange, the guaranteed anonymity of bids and the immediate publication of price information make a significant contribution to promoting fairness throughout the market.

Traded Products

In principle, all 24 hours of a day can be traded individually on the Austrian energy exchange. In addition to the standard block products (the combination of several hours into a common block) base, peak and off-peak, further special block products have been introduced in order to meet the specific needs of market participants (see figure 1). Besides the single-hour products and block products, all 96 quarter hours of a day can be traded at the EXAA in the independent 10:15 day-ahead auction. Since September 30, 2025, quarter-hour products can also be traded in the 12:00 market coupling auction.

The physical fulfillment of transactions takes place either in one of the four control areas in Germany (Amprion, TenneT, TransnetBW or 50Hertz) or in the Austrian APG control area. Since 2024 the control area in The Netherlands was added (Tennet), as well as in 2025 the french (RTE) and belgian control area (Elia).This results in the determination of a price per MWh for Germany and another price for Austria and the other control areas. On the trading days from Monday to Friday, the orders of the individual market participants are collected in a closed order book. An auction for gray and green energy is then held daily for each market area (Austria & Germany). The price determined at the auction (Market Clearing Price, MCP) and the quantities allocated to the individual market participants are communicated to them immediately after the auction, whereas the physical settlement of transactions takes place the next day (day-ahead trading).

In 2012, EXAA was the first European electricity exchange to enable its trading participants to trade in green electricity.

With downstream post-trading, surplus quantities from the auction can be bought at the already defined market clearing price.

Trading System

The products of the EXAA spot markets are traded in auctions. Only a web browser is required on the trader side to transmit buy or sell bids. This avoids software installation and maintenance on the traders' IT systems and expensive dedicated lines. Access to the system is secured with electronic keys (RSA tokens).
