Document structure

On this page you can find information about the structure and attributes of various documents related to the FFR market. The most important message types related to the FFR market are the bid document, reserve allocation result document, and the acknowledgement document.

General document rules

Dates and times should be in UTC, with the format YYYY-MM-DDThh:mm:ssZ. The last ‘Z’ stands for Zero and indicates UTC+0. The time period the document covers, however, should be in the same day in CET/CEST. This means the day is from 23:00 to 23:00 during winter time, and 22:00 to 22:00 during summer time.
When changing from winter time to summer time, the document covers 23 hours (from 23:00 to 22:00). When changing from summer time to winter time, the document covers 25 hours (from 22:00 to 23:00).
Each document must have a unique identifier in UUID format.
Bid Document

Bids are submitted to the FFR Market as ReserveBid_MarketDocument. Currently version 7.1 of the document schema is used. The document contains one or multiple Bid Time Series along with other document-wide information.

Bid Time Series

The bid time series contains attributes related to individual bids. A Bid document may contain multiple Bid Time Series. For multiple bids or periods in a message, create a timeseries for each bid. When submitting FFR-FCR combination bids, the FCR bids will use the structure of FCR Bid Time Series, described in the FCR Document Structure page.

Reserve Allocation Result Document

The Reserve Allocation Result document is a report sent to the BSP after the MTU containing information of the price and volume of activations during the MTU. No reference to the actual bids is included in the document; Per-bid results are sent in a separate document. The message is only sent if the receiving BSP has submitted bids that day. The FFR allocation document does not contain information of FCR parts of combination bids.
