2016-01 | On November 19, 2015, the Federal Energy Regulatory Commission (Commission) issued Order 3/6/2017 NERC TOP-001-4 No. 817 approving nine TOP and IRO standards from Project 2014-03 and retiring or superseding its IRO-002-5 18 currently-enforceable standards. The proposed standards were developed in Project 2014-03 to address Commission concerns and reliability issues identified in the 2011 Southwest Outage 2/9/2017 Report, the Independent Experts Review Panel project, and stakeholder technical conferences. In Approved by approving the new TOP and IRO standards, the Commission issued three directives to modify the NERC Board TOP and IRO standards to address additional reliability issues. 12/12/2016 Purpose/Industry Need Final Ballot The modifications to TOP and IRO standards developed in this project will address the IRO-002-5: following reliability concerns identified in Order No. 817: 74.3% Monitoring non-Bulk Electric System facilities. The Commission noted that "in some TOP-001-4: instances the absence of real-time monitoring of non-BES facilities by the transmission 72.52% operator within and outside its TOP area as necessary for determining SOL exceedances in proposed TOP-001-3, Requirement R10 creates a reliability gap." (P.35) 10/17/2016 Redundancy and Diverse Routing of Data Exchange Capabilities. The Commission Additional Ballot: determined that, with respect to data exchange capabilities, the TOP and IRO standards IRO-002-5: requirements for Reliability Coordinators (RCs), Transmission Operators (TOPs), and 70.77% Balancing Authorities (BAs) "do not clearly address redundancy and diverse routing so TOP-001-4: that registered entities will unambiguously recognize that they have an obligation to 68.85% address redundancy and diverse routing as part of their TOP and IRO compliance obligations." (P. 47) 8/3/2016 Testing of the Alternate or Less Frequently Used Data Exchange Capability. The Commission Initial Ballot determined that existing requirements do not establish a clear obligation for RCs, TOPs, and BAs IRO-002: 67.25% to test alternative data exchange capabilities (P. 51). TOP-001: 64.59% 2/22/2016 SAR Comments
