At the grid area borders of TSOs ČEPS, a.s./PSE S.A. and 50Hertz, not enough transfer capacity is available due to the high demand for electricity transmission, especially from east to west.
The complexity of physical and commercial interactions at the grid area borders between Germany, Poland and the Czech Republic requires both a high level of quality as well as a correspondingly high degree of coordination for the allocation method. These requirements are met through the allocation of the limited available transfer capacities in the scope of coordinated explicit auctions by JAO S.A. The transmission capacity of the KONTEK high voltage direct current cable between Denmark and Germany connecting the transmission system of Energinet.dk with that of 50Hertz Transmission GmbH (KONTEK link) is limited for technical reasons. Due to the great interest in power transmission, both from north to south and from south to north, the available capacity of the KONTEK link is provided to market participants on an annual / monthly basis through explicit auctions and on a daily / intraday basis through implicit auctions. The explicit auctions are handled by JAO S.A., the implicit auctions by the Nord Pool Spot AS (NPS) since the introduction of the Multi-Regional Coupling (MRC) in the north-western European region.
Information on the explicit auctions is provided on the JAO S.A. (www.jao.eu), information on the implicit auctions is available on the NPS website (www.nordpoolspot.com).
Changes to the current procedure are published on our website.
The capacities made available on the market by 50Hertz for the transmission of electrical energy are determined based on the "Procedures for cross-border transmission capacity assessments" described on the www.entsoe.eu website.
