• Reduces time to post collateral from two Bank Business Days to one (exception: Municipalities, Electric Cooperatives, or an Entity created under Texas Water Code (TWC) §222.001, may continue to take two Bank Business Days to post collateral agreements). 
• Creates a working credit limit which allows an entity to utilize up to 85% of posted collateral + unsecured credit limit (rather than 100%).
• Reduces time to cure a payment breach under QSE, LSE and TCR.

This Nodal Protocol Revision Request (NPRR) adds statements allowing ERCOT the option of cancelling commitments, prior to breaker close, previously issued through RUC.

Additional non-substantive administrative revisions, such as correcting defined term and acronym usage, are shown with the author “ERCOT Market Rules.”

This Nodal Protocol Revision Request (NPRR) allows ERCOT to procure additional Responsive Reserve (RRS) during cold weather conditions.

This Nodal Protocol Revision Request (NPRR) addresses several issues related to Ancillary Services.

 First, this NPRR revises Protocol Section 4.4.7.4 to add the following description regarding the timing associated with a Qualified Scheduling Entity’s (QSE’s) obligation to deliver the physical Ancillary Service capacity that it has self-arranged or sold to ERCOT from its designated Resources during the Operating Hour.  The QSE’s obligation begins at the top of each Operating Hour and ends with the top of the next Operating Hour and is continuous throughout the Operating Hour. 

Secondly, this NPRR introduces a penalty factor to increase charges to each QSE that fails to provide Ancillary Service capacity as described in Protocol 6.4.8.1.3, Replacement of Ancillary Service Due to Failure to Provide.  The penalty factor is defined as a multiplier that is applied to each of the charge calculations defined in Section 6.7.2.  The penalty factor equals ten for Regulation Up (Reg-Up), Regulation Down (Reg-Down), and Responsive Reserve Services (RRS) and five for Non-Spinning Reserve (Non-Spin) Service.

Finally, this NPRR:

• Adds an ERCOT monitoring requirement to the Section 8.1 grey box for Ancillary Service capacity performance metrics for failure to provide Ancillary Service capacity; and
• Adds performance criteria to Section 8.1.1.3 that apply to events that occur when QSEs are unable to meet their Ancillary Service Obligations because of an inability to deliver an Ancillary Service due to a failure to provide (refer to Protocol Section 6.4.8.1.3).  Protocol Section 6.4.8.1.3 allows the QSE the opportunity to replace this undeliverable Ancillary Service capacity, within a time frame acceptable to ERCOT or, otherwise, ERCOT is authorized to use the Supplemental Ancillary Services Market (SASM) or emergency operations processes to replace the Ancillary Service capacity.  The additions to Section 8.1.1.3 allow ERCOT the option to revoke a QSEs Ancillary Service qualification and/or a Resource’s Ancillary Service qualification to provide Ancillary Services when the undeliverable Ancillary Services capacity is not replaced by the QSE, and when such events have occurred more than three times in a month, aggregated for all such events that occur in the month.
