As announced in the Customer Information on 18 May 2017, the EEX Exchange Council has decided in its meeting today how the Phelix-DE/AT will be determined after a split of the common DE/AT-bidding zone.
The Exchange Council adopted the proposal of the Management Board of the Exchange. Beginning with the introduction of congestion management on the German-Austrian border, Phe-lix-DE/AT will be calculated as a weighted average of the hourly prices for Germany (𝑃DE) and Austria (𝑃AT) as determined in the respective Day-Ahead Auctions by EPEX SPOT. The weighting of DE:AT will be set to 9:1, so that the Phelix-DE/AT for every hour of the respective delivery period will be calculated as 110(9𝑃DE+ 𝑃AT). This weighting takes into account the ratio of the yearly average production and consumption in the national markets Germany and Austria.
The Management Board of the Exchange will assess annually in June, earliest in 2020, whether the facts on which the determination of the weighting have been based, have significantly changed such an adjustment be required. If this should be the case, the Exchange Council may decide upon the proposal of the Management Board of the Exchange to adjust the weighting. The adjusted weighting will apply uniformly to all delivery periods beginning on 1 January following the review. Pursuant to the decision of the Exchange Council such adjust-ment may occur at the earliest with effect as of 1 January 2021.
