On completion of successful IT tests, the Italian transmission system operator Terna and APG have now introduced a capacity auctioning mechanism for intraday on the common border between Austria and Italy.
The first capacity allocation took place on 28 May (energy delivery date: 29 May 2013). This cooperation aims to simplify cross-border energy trade and reconcile the principle of congestion management at this transfer point with the provisions of Regulation 714/2009 (EU) and the Congestion Management Guidelines. In addition, the process for the nomination of schedules was fully harmonised with the SO-SO matching approach used in the CEE region.
Given that the Italian market is currently not compatible with continuous trading, a decision was taken to organise two additional auctions on the day before the energy delivery ("day-ahead") as well as on the day of the energy delivery.
APG currently allocates intraday on all boarders through explicit PTR auctions (physical transmission rights), with the exception of the DE-AT border where an implicit link (with the possibility of an intraday stop) is guaranteed through EPEXSpot. The intraday allocation is carried out by CEPS (HU-AT and CZ-AT borders) and ELES (SI-AT borer). The Central Allocation Service Company ("CASC") in Luxemburg is responsible for auctions on the common border with Italy.
