How Does the Algorithm Work?

EUPHEMIA, i.e. the algorithm developed for SDAC, is used for the purpose of IDAs. The public description of EUPHEMIA (applicable to IDA and to SDAC) is available in the following link: https://www.nemo-committee.eu/assets/files/euphemia-public-description.pdf  


High-Level Architecture

  • XBID is used as source of network constraints data for IDA (pre-coupling) and to validate the IDA results in terms of capacity meeting the network constraints (coupling).
  • Network data are provided via NEMOs to EUPHEMIA (auction algorithm).
  • IDA results are submitted to XBID to update the information about Already Allocated Capacity (AAC) in XBID and to reflect in relevant CMM files the existence of capacity reserved for IDA results.
  • IDAs Trading Solution is the same solution as used for day-ahead being adapted for IDAs, depending on each NEMO.
  • IDA CIP is an intermediate system (interface) between XBID and NEMO Systems.


Products & Order Types

IDAs solution supports hourly, half-hourly and quarter-hourly products.

However, for the time being simple orders of only one time resolution are allowed in each BZ.

Additional order types  supported are simple block order and merit order.
