NOTICE DATE: October 19, 2023

NOTICE TYPE: M-A101923-01 NPRR/SCR

SHORT DESCRIPTION: Implementation Details of NPRR1026, PGRR081, NPRR1164, RRGRR033

INTENDED AUDIENCE: All Transmission Service Providers and Resource Entities

DAYS AFFECTED: November 19, 2023 and thereafter

LONG DESCRIPTION: On November 19, 2023, Protocol language associated with Nodal Protocol Revision Request (NPRR) 1026, BEST- 7 Self-Limiting Facilities; and Planning Guide language associated with Planning Guide Revision Request (PGRR) 081, Related to NPRR1026, BESTF-7 Self-Limiting Facilities, will be implemented.

Under NPRR1026 and PGRR081, Resource Entities will need to state in the Resource Integration and On-going Operations (RIOO) System whether their Resources are part of a Self-Limiting Facility.

Additionally, on November 19, 2023, system functionality associated with NPRR1164, Black Start and Isochronous Control Capable Identification; and Resource Registration Glossary language associated with Resource Registration Glossary Revision Request (RRGRR) 033, Related to NPRR1164, Black Start and Isochronous Control Capable Identification, will be implemented. 

NPRR1164 requires that Resource Entities identify whether a physical Resource has the potential capability (even if unverified) to be called upon or used during a Black Start emergency or if it has the capability for isochronous control, and requires that Resource Entities and Transmission Service Providers (TSPs) identify if a breaker or switch has a Synchroscope or Synchronism Check Relay; and defines the terms Black Start Capable Resource, Isochronous Control Capable Resource, Synchroscope, and Synchronism Check Relay. 

RRGRR033 adds the following requirements for Resource Entities to update in the RIOO System. Resource Entities should identify whether its Resource is:

• a Black Start Capable Resource,
• an Isochronous Control Capable Resource; or
• part of a Self-Limiting Facility.

In the RIOO System, Resource Entities should therefore identify if a modeled breaker or switch it operates  or directs the operation of, utilizes a Synchroscope and or Synchronism Check Relay.   

On December 1, 2023, Protocol language associated with NPRR1164 and Resource Registration Glossary language associated with RRGRR033, will be implemented.

ACTION REQUIRED: After implementation, Resource Entities should update the information in the RIOO application to comply with the requirements stated above. TSPs should continue to update the Network Operations Model to identify if a modeled breaker or switch it operates or directs the operation of utilizes a Synchroscope and or Synchronism Check Relay in accordance with arrangements identified in the Network Data Support Working Group (NDSWG) meetings.

ADDITIONAL INFORMATION: TSPs can continue their current progress in updating the information for their breakers or switches in accordance with arrangements identified in the NDSWG meetings and should not wait for the RIOO implementation to occur since the Network Operations Model can already accommodate the breaker and switch information needed to comply with NPRR1164 and RRGRR033.
