Query Parameters

Required query parameters:

start: Start specifies the start of the time interval for which to retrieve bids, e.g. 2025-06-17T12:00:00Z (RFC3339 in UTC).

end: End specifies the end of the time interval for which to retrieve bids, e.g. 2025-06-18T12:00:00Z (RFC3339 in UTC).

Optional query parameters:

markets: Returns bids for requested markets as a comma separated string, e.g. FCR,AFRREnergy. If not set, returns all markets. Available options (case sensitive): FCR, AFRREnergy, AFRRCapacity.

productDirections: Returns bids for requested product directions as a comma separated string, e.g. NEGPOS,POS. If not set, returns all product directions. Available options (case sensitive): POS, NEG, NEGPOS.

Response format

Returns a JSON representation of the ancillary bids for the given time interval and virtual asset as a list. The following fields are provided:

market: The market of the bid, one of: FCR, AFRREnergy, AFRRCapacity.

product: The product of the bid, e.g. NEGPOS_00_04 (FCR), POS_00_04 (AFRR Capacity), POS_001 (AFRR Energy).

deliveryDay: The delivery day of the bid in the format YYYY-MM-DD, e.g. 2026-05-30 (full day according to RFC3339).

bids: A list of individual bids for the product.

Each bid in the list contains the following fields whose contents can vary depending on the market:

bidID: The ID of the bid.

offeredCapacity: The offered capacity of the bid in kilowatts, e.g. 2000.

capacityPrice:

• AFRR Energy: This field is null.
• AFRR Capacity: The capacity price of the bid in EUR/MW/h, e.g. 100.00. This price is used to determine the position of the bid in the TSO’s merit order.
• FCR: The capacity price of the bid in EUR/MW, e.g. 100.00. This price is used to determine the position of the bid in the TSO’s merit order.

energyPrice:

• AFRR Energy: The energy price of the bid in EUR/MWh, e.g. 100.00. This price is used to determine the position of the bid in the TSO’s merit order.
• AFRR Capacity: The energy price of the 16 implicit AFRR Energy bids in EUR/MWh, e.g. 100.00. When submitting a bid into the AFRR Capacity market, it is mandatory to place 16 implicit AFRR Energy bids covering the 4 hour duration of the Capacity bid. This is done by providing an energyPrice on each Capacity bid. Each of the 16 Energy bids will have the same offeredCapacity as the corresponding Capacity bid. These Energy bids can still be updated after the Capacity bid has received a result. However, if the Capacity bid was accepted, the offeredCapacity of the Energy bids cannot be reduced. If the Capacity bid is rejected, the implicit Energy bids are also rejected.
• FCR: This field is null.

status: The status of the bid, one of: pending, submitted. submitted confirms that the bid has been placed successfully with the TSO. pending indicates that the process of placing the bid with the TSO is still in progress. While a bid has status pending, it cannot be updated to avoid double bidding.
