INTENDED AUDIENCE: All Market Participants

DAYS AFFECTED: May 27, 2022

LONG DESCRIPTION: On May 27, 2022, Protocol and Other Binding Document language associated with the following Revision Requests will be implemented:

The combination of the above Revision Requests allow for Non-Spinning Reserve (Non-Spin) provision from Load Resources that are not Controllable Load Resources and defines how Resources providing Non-Spin are grouped and deployed.

Technical specifications of the changes to ERCOT interfaces as a result of this effort were shared at the February 10, 2022 Technology Working Group meeting. ERCOT also hosted an April 25, 2022 workshop to provide additional details on this effort. 

ERCOT Market Operations Test Environment (MOTE) is available for Market Participants to voluntarily test submission functions related to NPRR1093, which began May 5, 2022.

Additionally, there will be several reporting changes introduced with the implementation of NPRR1093. Please note that changes to disclosure reports will occur post implementation and align to the applicable operating days affected.

The following new Certified reports will need to be added to the EMIL and MIS:

1) Monthly Non-Spin NCLR Performance Report | NP8-385-ER | Report Type ID 22069
2) Group Assignments for NCLRs and Off-Line Generation Resources Participating in NSRS | NP6-577-CD | Report Type ID 21939

The following two reports will have a column added for ‘RTNCLRNSCAP’:

1) Real-Time ORDC and Reliability Deployment Price Adders and Reserves by SCED Interval |NP6-323-CD| Report Type ID 13221

2) Historical Real Time ORDC and Reliability Deployment Price Adders and Reserves |NP6-792-ER| Report Type ID 13231

The following reports will be modified for the NSPIN Column to be split out to account for new subtype of NSPNM:

1) 60D SCED Disclosure Report | NP3-965-ER | Report Type ID 13052
Output file:  Output file: 60-Day QSE-Specific Self-Arranged AS in SCED

2) 60D DAM Disclosure Report | NP3-966-ER | Report Type ID 13051
Output file:  Output file: 60-Day QSE-Specific Self-Arranged AS in DAM

Lastly, a new output file will be added within the zipfile for 2-Day Ancillary Services Disclosure |NP3-911-ER | Report Type ID 13057

AS ‘2d_Self_Arranged_AS_NSPNM’ due to new NSPNM subtype

ACTION REQUIRED: Impacted Market Participants should implement changes to their shadow Settlement systems to incorporate the revisions made by NPRR1093, NPRR1101, OBDRR032, OBDRR033, and OBDRR035.
