State of Energy and State of Charge endpoints — /organisations/{organisationID}/virtual-assets/{virtualAssetID}/state-of-charge and /organisations/{organisationID}/virtual-assets/{virtualAssetID}/state-of-energy | 22 May 2026 — end of life. After this date the endpoints continue to work but are no longer actively maintained.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. |
