Graph Trend Definitions
• Telemetered SCE: Sum of all QSE’s Telemetered SCE (uses “Left” scale).• Regulation Deployed: Sum of all Regulation Ancillary Service. PLUS = increase
generation, MINUS = decrease generation. (uses “Left” scale).• Responsive Deployed: Sum of all Responsive Ancillary Service. Positive Only. (uses
“Left” scale).• Balancing:Balancing awarded: Sum of all QSE’s award. (uses “Left” scale)• Spinning Reserve: Sum of all QSE’s telemetered Spinning Reserves. (uses “Left” scale.)• Total Generation: Sum of all QSE’s “Total Generation” telemetered to ERCOT. (On
some NOI’s this may include bilateral purchases/sells). (uses “Right” scale.)• BPS & Dynamic: Sum of all QSE’s Base Power Schedules and Dynamic Schedules.
Most QSE’s have one or the other, some have both. (uses “Right” scale).• OLC “On-Line Capacity”: Sum of all QSE’s – Sum of Total Generation and Spinning
Reserve as telemetered from each QSE. (uses “Right” scale).• Obligation – Total Up Physical Obligation: Sum of all QSE’s. Sums for each QSE:
Base Power Schedule, Dynamic Schedule, Regulation “UP” Physical obligation, Responsive Physical obligation, any Non-Spin that has been deployed, Balancing Energy Deployed and Frequency Obligation (QSE bias times frequency deviation). (uses “Right” scale).
• Excess: Difference between “OLC” and “Obligation”: Sum for all QSE’s. MINUS = QSE’s “deficit” (uses Right scale).
• Load Imbalance: Difference between “Total Generation” and the sum of “Base Power Schedules and Dynamic Schedules”. (uses “Left” scale)
