Slovenian and Italian market coupling for Day-ahead electricity trading involves the simultaneous allocation of cross-border transmission capacities and electricity since January 1st, 2011.

In mid-October, BSP, in cooperation with Borzen and ELES, enabled Intraday electricity trading and clearing within a single application, offering improved user-friendliness and better market liquidity.

The Italian Borders Market Coupling links the Italian borders with the Multi-Regional Coupling (MRC) and demonstrates the flexibility and reliability of the Price Coupling of Regions (PCR) solution.

On 21 December 2015, BSP was designated by the Energy Agency as a Nominated Electricity Market Operator for 4 years, to perform the single Day-ahead and Intraday coupling within the territory of the Republic of Slovenia.

Slovenian and Italian regulatory agencies proposed a pilot Intraday market matching project at the border to ELES, TERNA, BSP, and GME. The project introduced implicit auctions for allocating Intraday cross-border transmission capacity and was completed on June 21, 2016.

BSP joined a multi-regional market merger in the central-southern European region, with operational implementation on the Slovenian-Italian border. A temporary market merger project was proposed and successfully completed on July 21, 2016, despite the classification of the Slovenian-Austrian border in the central European region.

On June 19th, 2018, the Slovenian-Croatian Market Coupling Project was launched, which demonstrates the flexibility and reliability of the Price Coupling of Regions (PCR) solution. The Go-Live is pending final approval by the regulatory authorities involved.

On June 8, 2022, the PXs and system operators of the Central European Region implemented Day-ahead market coupling in the CORE region by calculating available CZCs using the flow-based method after successful tests and simulations. The region includes market coupling operations at the Slovenian-Austrian, Slovenian-Hungarian, and Slovenian-Croatian borders.
