Market Coupling

Market Coupling is the use of an implicit auctioning system, where transmission capacity represents an input parameter in the exchange of offers between two or more power exchanges.

In cooperation with other European Power Exchanges and System Operators BSP successfully implemented a project of Day-ahead market coupling on Slovenian-Italian and on Slovenian-Austrian and Slovenian-Croatian border.

On the 22nd of June 2016 we have additionally introduced, as a European pilot project, an implicit Intraday market coupling on slovenian-italian border.

On 8. June 2022 BSP has entered with 10 nominated electricity market operators and 16 transmission system operators to the Core Capacity calculation region as part of day-ahead market integration. Since then, core calculation has been carried out on all borders except the Italian one.

The last interconnector that needed to be implemented was the Hungarian border on June 30, 2022. From a market point of view, it was included in the cross-border capacity calculation process from July 6, 2022 for trading at the Day Ahead auction, and from July 7, 2022 it was also added to intraday trading Continuous market.
