15.01.2021 Market Coupling Session with Partial Decoupling of EXAA on the 13th of January 2021

Within the scope of the 12:00 market coupling auction on 13.01.2021 for the delivery day 14.01.2021, a partial decoupling of EXAA as NEMO for the market area Austria and Germany occurred.

The cause of the partial decoupling was a technical problem with EXAA's Servicing Exchange. Despite intensive efforts in accordance with the relevant European Market Coupling Procedures, the problem could not be resolved within the specified period.

In compliance with the rules for the commodity exchange and the rules of market coupling as well as the associated time processes, EXAA made an effort to provide its trading participants with sufficient reaction time and at the meantime to ensure full transparency and clarity with regard to the entire auction process. On the basis of the remaining order situation, a fair market clearing price was calculated according to the circumstances. However, it differed greatly from the European market clearing price. Attempts at market manipulation can be ruled out.

As you can find in the message from SDAC JSC, an in-depth investigation has been initiated and EXAA is in close contact with his Servicing Exchange to clarify the technical problems. We can already confirm that the cause has been identified and rectified.

We look forward to the next successful Market Coupling Session and hope that our trading participants will continue to have confidence in EXAA.

We are very happy to welcome Wien Energie GmbH as a new trading participant at EXAA!

08.09.2020 Invitation: SDAC Full-Decoupling training session 30 September 2020

Dear EXAA traders! 

EXAA is very proud to have been an integral part of the European market coupling process for over a year now! All - to date 434 - Day Ahead Market Coupling auctions have been successfully completed, with EXAA always being coupled.

The team of EXAA Market Operations demonstrates its readiness for action on a daily basis and is always well prepared for any emergency.

In order to give you as a trading participant the chance to check how familiar you are with the European market coupling procedures, there will be an official joint test session at SDAC (Single Day Ahead Coupling) level on Wed, 30 September 2020 covering a full-decoupling scenario. A technical problem in the central price calculation will be simulated, which will finally result in shadow auctions for cross-border capacities and local auctions at the individual NEMOs. Here you will find the first common communication of all SDAC members. Further details on the test procedure will follow soon.

All parties involved (exchanges/NEMOs, TSOs, CCPs and JAO) and especially we as EXAA hope for a very active participation of our EXAA members and kindly ask you to officially register for the test with the EXAA Market Operations team via trading@exaa.at by Friday, 25 September 2020. We will then be happy to provide you with all necessary information.

Use this test to reduce your daily operational risk by:

  • training the handling of the EXAA trading system for the 12:00 Market Coupling auction,
  • live a local, simulated decoupled auction at EXAA,
  • strengthen your understanding of the "operational messages" used within the Day Ahead Market Coupling process
  • and thus to shorten your reaction time in extreme cases.
     

We look forward to your participation!
