Status
A 45-day formal comment period is open through 8 p.m. Eastern, Monday, August 3, 2020 for the following standards and implementation plan:
  • CIP-014-3 – Physical Security
  • FAC-003-5 – Transmission Vegetation Management
  • FAC-011-4 – System Operating Limits Methodology for the Operations Horizon
  • FAC-013-3 – Assessment of Transfer Capability for the Near-term Transmission Planning Horizon
  • FAC-014-3 – Establish and Communicate System Operating Limit
  • PRC-002-3 – Disturbance Monitoring and Reporting Requirements
  • PRC-023-5 – Transmission Relay Loadability
  • PRC-026-2 – Relay Performance During Stable Power Swings
  • TOP-001-6 – Transmission Operations
  • IRO-008-3 – Reliability Coordinator Operational Analyses and Real-time Assessments
  • Implementation Plan

Ballot pools are being formed through 8 p.m. Eastern, Monday, July 20, 2020. NERC staff made the decision to re-open the older, existing ballot pools to allow stakeholders to join if desired.

Ballots for the standards and implementation plan as well as non-binding polls of the associated Violation Risk Factors and Violation Severity Levels will be conducted July 24 – August 3, 2020.

 

Background
Facilities Design, Connections, and Maintenance (FAC) standards fulfill an important reliability objective for determining and communicating System Operating Limits (SOLs) used in the reliable planning and operation of the Bulk Electric System (BES). This project will revise requirements for determining and communicating these SOLs. Revisions are necessary to improve the requirements by eliminating overlap with approved Transmission Planning (TPL) requirements, enhancing consistency with Transmission Operations (TOP) and Interconnection Reliability Operations (IRO) standards, and addressing issues with determining and communicating SOLs and Interconnection Reliability Operating Limits (IROLs).

 
Standards Affected: CIP-014-2 – Physical Security | FAC-003-4 – Transmission Vegetation Management | FAC-010-3 - System Operating Limits Methodology for the Planning Horizon | FAC-011-3 - System Operating Limits Methodology for the Operations Horizon | FAC-013-2 – Assessment of Transfer Capability for the Near-term Transmission Planning Horizon | FAC-014-2 - Establish and Communicate System Operating Limit | PRC-002-2 – Disturbance Monitoring and Reporting Requirements  | PRC-023-4 – Transmission Relay Loadability | PRC-026-1 – Relay Performance During Stable Power Swings | IRO-008-2  Reliability Coordinator Operational Analyses and Real-time Assessments | TOP-001-5 – Transmission Operations
 
Purpose/Industry Need
The project will revise the requirements for determining and communicating SOLs and IROLs to address the issues identified in Project 2015-03 Periodic Review of System Operating Limit Standards.  The resulting standard(s) and definition(s) will benefit reliability by improving alignment with approved TPL and proposed TOP and IRO standards. The project may result in development of one or more proposed Reliability Standards and definitions.
