## Abstract

On November 17, 2009, the North American Electric Reliability Corporation (NERC) submitted a petition requesting approval of NERC's interpretation of Requirement R1.3.10 of Commission-approved transmission planning Reliability Standard TPL-002-0 (System Performance Following Loss of a Single Bulk Electric System Element). In a March 2010 Notice of Proposed Rulemaking (NOPR), the Commission proposed to reject NERC's proposed interpretation, and instead proposed an alternative interpretation of Requirement R1.3.10 of Reliability Standard TPL-002-0. As a result of the comments received in response to the proposal, the Commission declines to adopt the NOPR proposal and approves NERC's proposed interpretation. In addition, as proposed by several commenters, the Commission directs NERC and Commission staff to initiate a process to identify any reliability issues, as discussed below.
