Related Files

Status
A 45-day formal comment period is open through 8 p.m. Eastern, Monday, November 13, 2017 for the following standards, implementation plan and definition:
·        FAC-010-3 - System Operating Limits Methodology for the Planning Horizon (retirement)
·        FAC-011-4 - System Operating Limits Methodology for the Operations Horizon
·        FAC-014-3 – Establish and Communicate System Operating Limit
·        FAC-015-1 - Coordination of Planning Assessments with the Reliability Coordinator’s SOL Methodology
·        Implementation Plan
·        Proposed Definition - System Voltage Limit
Ballot pools are being formed through 8 p.m. Eastern, Monday, October 30, 2017. Initial ballots and non-binding polls of the associated Violation Risk Factors and Violation Severity Levels will be conducted November 3-13, 2017.
Additionally, a 30-day informal comment period on the System Operating Limits (SOL) and SOL Exceedance definitions is open through 8 p.m. Eastern, Monday, October 30, 2017.
The draft Reliability Standard Audit Worksheets are posted for industry comment through Monday, November 13, 2017.
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: FAC-010-3 - System Operating Limits Methodology for the Planning Horizon | FAC-011-3 - System Operating Limits Methodology for the Operations Horizon | FAC-014-2 - Establish and Communicate System Operating Limit
 
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.
