Example of various intertie resource bidding options and the corresponding CAS e-Tagging rules

FERC Order 764 Compliance 15-Minute Scheduling and Settlement

Version 1.0

January 21, 2014

Intertie resources must submit hourly bidding options in SIBR. The bidding options are:

1. If it is hourly block scheduled or not (in SIBR = “Hourly”)

2. If it is hourly block with one time intra-hour change allowed or not (in SIBR = “Once”)

Case 1: FMM participating with economic bids

The intertie resource’s bidding options is selected as NO (not “Hourly” or “Once” in SIBR) for HE10 and HE11. The intertie resource submits an economic bid of [0,100MW] at $10/MWh for two hours. In this case, the intertie resource participates in the 15-minute market with economic bids.

RTUC run #1 executed at 8:52.5 and completed at 9:07.5. This is the HAP process for HE11.
