ATC Equation
|
ATC = TTC (allocated)- Committed Uses
|
|
|
How is TTC determined?
|
TTC is determined through peer-reviewed engineering studies using the WECC Reliability Criteria for Transmission System Planning
|
|
|
Committed Uses Formula
|
TRM + Existing Transmission Commitments (incl. CBM)
|
|
|
TRM
|
Transmission Reliability Margin
|
|
|
CBM
|
Capacity Benefit Margin
|
|
|
What does 'Committed Uses' include?
|
Forecasted Monthly Peaks and Forecated Preschedule Hourly Schedules for Native Load, Network Load, and Long Term Point-to-Point Transmission Reservations and Existing Transmission Contracts.
|
|
|
Scheduling horizon
|
Real-Time - initially calculates after the Daily initialize runs at noon and then goes from the current hour plus 8 hours. In addition an Hourly Initialize runs between the top of the hour and 10 minutes after the top of the hour extending of sliding out one hour at a time during real time.
|
|
|
Operating Horizon
|
Preschedule - A daily initialize runs at noon each day and runs to the end of the Preschedule day per the WECC Preschedule day per the WECC Preschedule calendar.
|
|
|
Planning Horizon
|
Future beyond the Preschedule out through 10 years.
