What is the current procedure defined for scheduling PARS and can an example be provided?
The current procedure for scheduling PARs in the DAM is described in the Day-Ahead Manual. The process uses the previous “like” day’s historical hourly average. Since this process is being run at 5:00 am for the next day, the actual flows are two days behind (i.e. on Tuesday at 5:00 am, Wednesday’s DAM is being run and the last 24 hours of PAR flow is from Monday). The process for scheduling PARS was discussed at the Operating Committee, and the associated presentation material from this meeting is posted on the NYISO website under “Services, Board of Directors…, Operating Committee, July 25, 2002, “Presentation – NYISO PAR Scheduling”, or use the following link: PAR PAR Schedules are initially based on the prior like day’s schedule, as previously described. Then patterns are applied to filter out transient operational flows. The specific pattern utilized was developed based on historical PAR settings. Additionally, schedules are adjusted for any forecasted network outages. Finally,
