Auctions of transmission capacities - General Information
As of 1 May 2004, traders active on the Polish electricity market are enabled to use system interconnectors and thereby transmit electricity between the Polish power system and the interconnected synchronously operating systems. The congestion management mechanism has been implemented. It ensures that transmission capacity is made available to market participants according to competitive market-based rules.

Interchange Scheduling
Polish Market Participants submit the day ahead cross border schedules according to ESS standard (ETSO Scheduling System). The identification of transactional parties is made on the basis of Energy Identification Coding Scheme (EIC). There are two possible ways to submit the schedules: the dedicated Electronic Data Interchange system WIRE or web based interface WIRE RP. The description of the whole process of the interchange scheduling is included in the Instruction of Transmission System Operation and Maintenance (Instrukcja Ruchu i Eksploatacji Sieci Przesy³owej – Polish version only).
