06/10/2008 TPTF To endorse submitting these revisions as TPTF comments to Protocol Revision Subcommittee (PRS) and identified the functionality as "approved post go-live" (i.e., the functionality is needed for the nodal market, but can be deferred past the Texas Nodal Market Implementation Date (TNMID) and should be funded as part of the nodal project). TPTF will revisit NPRR131 after the impact study is available to determine if NPRR131 can be classified as "needed for go-live" (i.e., the functionality must be available on the TNMID). Passed

Background

Status: Approved
Date Posted: May 15, 2008
Sponsor: NRG Texas
Urgent: No
Sections: 2.1, Definitions; 4.3, QSE Activities and Responsibilities in the Day-Ahead; 4.4.7.1, Self-Arranged Ancillary Service Quantities; 4.4.7.3, Ancillary Service Trades; 4.4.7.4, Ancillary Service Supply Responsibility; 4.4.10, Credit Requirement for DAM Bids and Offers; 4.5.1, DAM Clearing Process; and 4.6.4.2, Charges for Ancillary Services Procurement in the DAM
Description: Allow all QSEs, whether they represent Resources, Loads, or both, to procure AS in the Day DAM.
Reason: In today’s zonal market, Resource Eentities can, if they choose, procure AS from ERCOT. This functionality was inadvertently omitted in the nodal design. Currently, the nodal design only allows QSEs with AS Obligations the option in the DAM of either: 1) self-providing, or 2) procuring all or a portion of their obligation from ERCOT. This NPRR would allow QSEs with AS responsibilities, i.e., Resource Entities, the same functionality.
