Geographical Expansion of SDAC Market Coupling Auction

27.01.2026

EXAA expands its access to Market Coupling Auction in France, Belgium and the Netherlands

 

EXAA continues to strengthen its role as a trading hub for European day-ahead power markets by expanding its Market Coupling Auction to France, the Netherlands, and Belgium. The extended market configuration went live on 27 January 2026, further advancing EXAA’s expansion within the Single Day-Ahead Coupling (SDAC).

As a Nominated Electricity Market Operator (NEMO), EXAA provides its members with efficient and cost-effective access to the pan-European day-ahead energy market via the 12:00 Market Coupling Auction. With the integration of France, the Netherlands, and Belgium, market participants gain seamless access to additional bidding zones through the established EXAA trading system.

 

A key highlight of this expansion is the extension of the Cross-Auction Spread product to the newly integrated markets. With today’s go-live, Cross-Auction Spreads are now available for Belgium, France, and the Netherlands, in addition to the existing markets Austria and Germany.  This product adds interesting new trading opportunities in multiple European markets.

The Cross-Auction Spread enables participants to directly trade the price difference between the EXAA 10:15 Early Auction and the 12:00 Market Coupling Auction. This allows traders to efficiently position themselves across both auctions and benefit from optimized collateral usage.

 

EXAA looks forward to welcoming market participants to the expanded Market Coupling Auction and the extended Cross-Auction Spread offering, supporting a smooth and successful start in all newly integrated markets!
