Methodology

The day-ahead market clears once each day via the EU Single Day-Ahead Coupling (SDAC). Since 1 October 2025, each connected bidding zone gets one price per 15-minute market time unit for tomorrow; older observations are hourly. Nord Pool runs the matching for the Nordic-Baltic region.

The clearing price is the highest accepted bid in each direction (sell / buy) at the equilibrium volume. Every accepted seller and buyer pays / receives this single uniform price.

FAQ

Why does Finland sometimes have a different price than Sweden?
When cross-border transmission capacity is full, prices decouple. Finland connects to Sweden (SE1/SE3) and to Estonia via the EstLink cables; when those lines are at capacity, the Finnish price separates from its neighbours.
Is the next day already shown?
After the SDAC auction publishes, tomorrow’s 96 quarter-hour prices are appended to this feed. Before publication, the feed ends with the latest already-cleared delivery interval.
