Gets all aFRR bids for a given virtual asset and delivery day

Query Parameters

Required query parameters:

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

Optional query parameters:

market: Returns bids for requested market aFRR market only, e.g. capacity. If not set, returns all markets. Available options (case sensitive): capacity, energy.

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:

productDateCode:

The productDateCode in the response references a specific product on a given delivery day: e.g. 2025-01-01_POS_00_04.

This “product-date-code” can be used to update the bid individually through the PUT endpoint.

product: The product of the bid, e.g. 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:

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.

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.
