The Instantaneous SOC is the amount of energy in MWh that the battery, in real time, has available for CAISO participation. The SOC will be maintained within energy limit constraints (minimum and maximum) defined in the CAISO Master File. Data should be updated every four seconds and should vary from zero to maximum energy limit.
The Maximum Continuous Energy Limit is the maximum energy in MWh that can be stored in the battery for CAISO participation. This value cannot be above the maximum energy limit defined in the CAISO Master File. The derate should be reflected, when applicable, in real time.
The Instantaneous SOC is the amount of energy in MWh that the battery, in real time, has available for CAISO participation at the time this value is conveyed through telemetry. This value should be between the Minimum Continuous Energy Limit and Maximum Continuous Energy Limit as registered in the Master File, adjusted by any applicable outage, derate, or rerate. The SOC will be maintained within energy limit constraints (minimum and maximum) defined in the CAISO Master File. Data should be updated every four seconds and should vary from zero to maximum energy limit.
The Maximum Continuous Energy Limit is the maximum energy in MWh that can be stored in the battery for CAISO participation at the time this value is conveyed through telemetry. This value should align with what is registered in the Master File, adjusted by any applicable outage, derate, or rerate. This value cannot be above the maximum energy limit defined in the CAISO Master File. The derate should be reflected, when applicable, in real time.
Updates to battery point definitions to add clarity to the Instantaneous State Of Charge (SOC) and Maximum Continuous Energy limit. A new Telemetry point added – Minimum Continuous Energy Limit.
