Sections:
3.1.5.3, Timelines for Response by ERCOT for TSP Requests
Description:
This Nodal Protocol Revision Request (NPRR) proposes two revisions in the table in Section 3.1.5.3(1):
The first revision proposes changing "three" to "four" to make the timeline internally consistent. The current wording could require approval of an Outage six hours prior to its submission.
The second revision proposes increasing the "approval window" for the 45-day timeline from five days to 15 days (as it is in Zonal Protocols).
Reason:
The reason for first revision is to add clarity and internal consistency.
The reason for the second revision is that the approval window for the 45-day timeline does not allow sufficient time to analyze the complicated Outages that typically occur during this time. The five-day window for any given Outage can include weekends and holidays during which Transmission Service Providers (TSPs) do not provide support to the Outage coordinators. As a result, ERCOT’s effective approval window is often reduced to two or three days. (An Outage submitted Friday afternoon must be approved on the following Tuesday). Overall, this results in an increased percentage of Outages submitted in the 45-day process being rejected or moved into the nine-day process due to insufficient information. This approval window, therefore, needs to be expanded. ERCOT Staff recommends that it be lengthened to 15 days, similar to the Zonal Protocols.
