26 November 2025, SIDC Press Release
As of 25 November 2025, European Power Exchange (EPEX SPOT) is connected to the Single Intraday Coupling (SIDC) Continuous framework in the Baltic region. This achievement is a direct result of implementing the Baltic Multi-NEMO Arrangements, completed by the regional integration project parties: AST, Elering, Nord Pool EMCO, EPEX SPOT, Fingrid, Litgrid, PSE, and SVK. Their joint effort ensures seamless operation across borders and bidding zones.
This change brings not only direct advantages for Estonia, Latvia and Lithuania, but also for the overall interconnected EU-wide region. The Integration of EPEX SPOT as an active NEMO across the Baltic region, based on Multi-NEMO Arrangements with Nord Pool, marks another important milestone for market participants, which will benefit from a market that becomes more liquid and increasingly competitive, thus maintaining consistency with the single market’s core objectives: efficient, fair and non-discriminatory market functioning.
Next Steps
Project parties will closely monitor performance and stability during the initial operating period. Future MNA waves will continue to expand geographic coverage and product scope, further enhancing the European Internal Electricity Market.
About SIDC:
The Single Intraday Coupling (SIDC) is a market mechanism in the intraday timeframe defined in the CACM Regulation based on continuous trading and complemented by three intraday auctions (so called “IDAs”).
The SIDC continuous trading solution is based on a common IT system with one Shared Order Book, a Capacity Management Module and a Shipping Module. It allows for orders entered by market participants for continuous matching in one bidding zone to be matched by orders similarly submitted by market participants in any other bidding zone within the European Intraday Coupling as long as transmission capacity is available. The intraday solution supports both explicit allocation (where approved by the respective National Regulatory Authorities) and implicit continuous trading. It is in line with the EU Target model for an integrated intraday market.
In addition, SIDC IDAs allow for the pricing of cross-border capacity in the intraday timeframe. IDAs are implicit auctions where collected orders are matched, and cross-zonal capacity is allocated simultaneously for different bidding zones, determining clearing prices for each bidding zone.
European-wide intraday coupling is a key component for completing the European Internal Energy Market. With the rising share of intermittent generation in the European generation mix, connecting intraday markets through cross-border trading is an increasingly important tool for market parties to keep positions balanced. The purpose of the SIDC is to increase the overall efficiency of intraday trading.
