Intraday Flow-based

The intraday market is currently based on ATC (Available Transfer Capacity). 

The implementation project for the flow-based methodology in the intraday timeframe started in the beginning of 2025. Scope of the project is to implement a functioning Intraday Market Coupling (ID MC) from capacity calculation to allocation. First target is to have flow-based in operation in Intraday Auctions (IDA). 

Nordic Flow-based Intraday is part of European level development. Single IntraDay Coupling (SIDC) is an initiative to create a single EU cross-zonal intraday electricity market. SIDC covers the continuous market (IDC) and Intraday Auctions (IDA).
