It is not allowed to include bids for any time period where the gate is closed, even if they are unchanged from previously submitted bids.
  • Gate opening time for BSPs is D-30.
  • Gate closure time for BSPs is D-1 at 18:00 EET/EEST.

  • Recommended maximum number of bids within a bid document is 2000.
  • Bid documents, Allocation Result documents and Acknowledgement documents will be exchanged between the parties using the ECP/EDX network. If the EDX connection is not working properly, the BSP should, if possible, use the Vaksi Web UI as a back-up to check the status of the submitted bids.

Bid level rules

  • Bid volume can contain a maximum of 1 decimal
  • Bid price can contain a maximum of 2 decimals
  • Decimal separator must be a period

  • Both parts of a combination bid must be included in the same bid document
  • Linked bids must have the same volume and time interval
  • Linked bids can have different prices, as long as they are 0 or higher
  • Submitting party must have a valid contract with Fingrid for both FFR and FCR markets
  • Exclusive Bid Identifier must be unique for each combination bid

Acknowledgement rules

  • For each bid message received, an acknowledgement document is sent back to the BSP
  • Messages are never partially accepted, only fully accepted or fully rejected
  • The acknowledgement message contains the erroneuous timeseries and a reason text indicating the error
  • Document level error code is A01 for accepted message, A02 for fully rejected message.
