NERC Submits Comments on NOPR on Proposed Reliability Standard TPL-001-5

On August 26, 2019, in Docket No. RM19-10-000, NERC submitted comments on the Notice of Proposed Rulemaking (NOPR) regarding proposed Reliability Standard TPL-001-5 (Transmission System Planning Performance Requirements) issued by FERC on June 20, 2019. Proposed Reliability Standard TPL-001-5 improves upon currently effective Reliability Standard TPL-001-4 by providing more extensive planning studies. Specifically, this Reliability Standard requires each Planning Authority and Transmission Planner to perform an annual Planning Assessment of its portion of the BES covering a number of System conditions and Contingencies described in the standard. Additionally, the standard addresses two Commission directives from Order No. 786. The NOPR also proposes to direct NERC to modify the Reliability Standards to require corrective action plans for protection system single points of failure in combination with a three-phase fault if planning studies indicate potential cascading. NERC supports the Commission’s proposal to approve proposed Reliability Standard TPL001-5 and its associated elements. However, NERC does not support the Commission’s proposal to direct further modifications to the standard at this time.
