New features
New ancillary results and bids endpoints for physical assets
We have extended the ancillary API for physical assets with two new endpoints and richer response data on the existing results endpoint.
You can now retrieve ancillary results for a specific set of bid IDs without needing to know the delivery day, and look up bids filtered to a set of product keys:
GET /physical-assets/{physicalAssetID}/ancillary/results-by-bid-ids?bid-ids=<id1>,<id2>,... — returns results (with an exists flag) for each requested bid ID.GET /physical-assets/{physicalAssetID}/ancillary/bids-by-product-keys?product-keys=<key1>,... — returns bids filtered to the specified product keys.
The existing results endpoint (/ancillary/results) now also returns deliveryDay and product on each result, giving full context without a separate lookup.
This brings the level of information at a physical asset level in line with the information available at virtual asset level.
Logbook
We have shipped a new logbook feature for physical assets. You can now record, edit, and delete logbook entries and notes against individual assets and view all entries across a portfolio in one place. Each entry captures a start time, end time, and text description.
The logbook is accessible from the asset and portfolio pages in the webapp (Logbook tab) and is currently behind the asset-management feature flag. Please get in touch if you would like this enabled for your organisation.
Improvements
Ancillary capacity graphs — per-block available capacity
The FCR and aFRR day-ahead and intraday bid graphs in the webapp now display time-varying available capacity at each EFA block boundary, replacing the previously static single-value line. Tooltip labels have been updated from “Marketable Capacity” to “Available Capacity” to reflect this. The displayed capacity now tracks how ancillary headroom changes across the day as market positions evolve.Last modified on June 26, 2026
