XML message sent to Load Resources other than Controllable Load Resources for manual deployment of Responsive Reserve Service will be updated to show a value (MW) equal to the telemetered net power consumption
minus the telemetered Low Power Consumption (LPC). Currently, the XML message shows a value (MW) equal to the Responsive Reserve Responsibility.

NPRR626 adds following new telemetry points, as shown below, to communicate Real-Time On-Line Reliability Deployment information to the market using Inter-Control Center Communications Protocol (ICCP). For any
questions, please contact Client Services to get the ERCOT ICCP Support team help.
a.
