Status
A 45-day comment period for for TPL-001-5 – Transmission System Planning Performance Requirements is open through 8 p.m. Eastern, Friday, September 14, 2018.

The Implementation Plan has been updated to reflect a revised compliance date. The comment period has been extended to provide stakeholders adequate time to review the updated documents and provide meaningful feedback.

Additional ballots for the standard and implementation plan, and a non-binding poll of the associated Violation Risk Factors (VRFs) and Violation Severity Levels (VSLs) will be conducted September 5-14, 2018.

Background
The SPCS and the SAMS conducted an assessment of protection system single points of failure in response to FERC Order No. 754, including analysis of data from the NERC Section 1600 Request for Data or Information. The assessment confirms the existence of a reliability risk associated with single points of failure in protection systems that warrants further action.

Additionally, the two directives from FERC Order No. 786 (p. 40 and p. 89) and updates to the MOD reference in Requirement R1, Measure M1 and the Violation Severity Levels sections have been added to the scope of the project.
 
Standard(s) Affected: TPL-001-4 - Transmission System Planning Performance Requirements
 

Purpose/Industry Need
The proposed standard project will benefit reliability by providing clear, unambiguous and results-based reliability standard requirements to address the assessment’s recommendations for modifying NERC Reliability Standard TPL-001-4 (Transmission System Planning Performance Requirements) identified in the SPCS and SAMS report titled “Order No. 754 Assessment of Protection System Single Points of Failure Based on the Section 1600 Data Request.”
