Regionally coordinated auctions of cross-border transmission capacities between South East European Transmission System Operators

摘要

Coordinated Auction Office in South East Europe (hereinafter: SEE CAO) was established in 2014, after few years of intensive preparation, by its shareholders - TSOs from the region of South East Europe (HOPS, NOSBiH, CGES, OST, KOSTT, IPTO, TEIAS) - with the objective to perform the explicit allocation of cross-border transmission capacity in both directions between Control Areas of the Participating TSO's, through NTC based Auction Processes in accordance with the requirements of Regulation (EC) 714/2009 of the European Parliament and of the Council on conditions for access to the network for cross border exchanges in electricity which also became a part of Energy Community aquis in line with the stipulations of Energy Community Treaty. SEE CAO's Go-Live was in November 2014 by launching the first yearly auctions for 2015 on two borders. During the year 2015, SEE CAO was expanding its scope of serviced borders by including remaining borders between the shareholding TSOs into its Auction process. Nevertheless, in order to complete the regional perimeter, SEE CAO and its shareholders are open and ready to include the remaining SEE TSOs, as well as their borders, into SEE CAO Auction Process. The pertinence of SEE CAO, particularly for regional electricity market in SEE, is reflected in introduction of new products by upgrading previous unilateral auctions performed by each TSO on 50% of NTC following their national Auction Rules or bilateral auctions performed by two neighbouring TSO on 100% of NTC following bilateral Auction Rules to regionally coordinated auctions performed by SEE CAO, having in force one single set of the Auction Rules and the possibility for the traders to allocate cross-border capacity from Croatia to Turkey by using SEE CAO as one-stop-shop. Since the core service of the company is highly dependent on data provision, the technical framework for implementation of auction tool had to be met. Therefore, Auction Platform was developed and implemented based on SEE CAO technical specification and requirements from SEE CAO Auction Rules. The Auction Platform, as web based application, is implemented completely following the ECAN (ENTSO-E Capacity Allocation and Nomination) standard, supporting the modules for Long Term and Daily Auctions, Secondary Market, Capacity Rights and Nominations (UIOSI), Finance and Settlement. Users of the Auction Platform, besides SEE CAO Operators and SEE TSOs (shareholders which are at the same time service users), are numerous Auction Participants. Auction Platform enables their users to offer or allocate the cross-border capacities on yearly, monthly and daily level. Thus, the data exchange is enabled between Auction Platform and the users in accordance with the Electronic Data Interchange (EDI) library and standards, while the relevant data is also provided to ENTSO-E Transparency Platform. Taking into account SEE CAO operational period up till March 2016, where all yearly, monthly and daily auctions were successfully conducted and having in mind positive feedback received from up to 100 registered traders, SEE CAO has proven its pivotal role for open and competitive South East European electricity market.
