Successful Implementation of Complementary Regional Intraday Auctions (CRIDAs) Greece-Italy-Slovenia


On the 22nd of September 2021, three Complementary Regional Intraday Auctions (CRIDAs) were performed successfully  at  Greece-Italy interconnection thus completing a new milestone, after the day-ahead coupling that was achieved on the same border on the 15th of December 2020 and the day-ahead coupling at Greece-Bulgaria interconnection on 11th of May 2021.

This achievement is the result of cooperation between the System Operators of Greece (IPTO), Italy (TERNA) and Slovenia (ELES), as well as the Market Operators (HEnEx, GME and BSP) respectively. CRIDAs  represent  a further step towards the achievement of the single pan-European Intraday electricity market  and they are executed according to European Regulation CACM (Capacity Allocation & Congestion Management).

These auctions, which will be conducted on a daily basis, are expected to enhance the liquidity of the intraday market and provide additional position correction tools to participants in the Greek electricity market.

The next milestone  is the integration of Greek borders (GR-IT and GR-BG) to the Continues Intraday trading (XBID)  later in 2022.
