After this date the endpoints continue to work but are no longer actively maintained.        | Use `/organisations/{organisationID}/virtual-assets/{virtualAssetID}/operational` and specify the data categories `stateOfCharge` and `stateOfEnergy`. |
| **Legacy operational data category names** — `marketableCapacityAFRRPos`, `marketableCapacityAFRRNeg`, and `marketableCapacityFCR`                                                                                          | **19 June 2026** — end of life. Values returned using these data categories may be inconsistent or correct after this date. | Use `afrrPosCapacityAvailable`, `afrrNegCapacityAvailable`, and `fcrCapacityAvailable` instead when requesting operational data.                       |
