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.”
