Project 2015-09 Establish and Communicate System Operating Limits

Related Files

Status
A 45-day formal comment period is open through 8 p.m. Eastern, Monday, December 7, 2020 for the following standard and implementation plan:
  • FAC-014-3 – Establish and Communicate System Operating Limit
  • Implementation Plan

Ballots for the standard and implementation plan, as well as a non-binding poll of the associated Violation Risk Factors and Violation Severity Levels will be conducted November 27 - December 7, 2020. 


In order to maintain consistency with CIP-002 criteria language, the SDT will not be modifying CIP-014 during this project. The applicability language regarding the derivation of IROLs will not be changed in CIP-014. The SDT has made significant enhancements in the Facilities Design, Connections, and Maintenance (FAC), Transmission Operations (TOP) and Interconnection Reliability Operations (IRO) standards addressing issues with determining and communicating SOLs and Interconnection Reliability Operating Limits (IROLs). NERC is still evaluating approaches to the CIP-002 and CIP-014 language.

Also, due to the retirement of FAC-013 (see FERC Order No. 873), the revisions to standard will not move forward.

 

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.
