FERC Proposes Requiring Access to NERC Databases
The Federal Energy Regulatory Commission (FERC) today proposed to require the North American Electric Reliability
Corporation (NERC) to provide the Commission with access to NERC’s transmission availability data system, generating
availability data system and protection system misoperations databases.
The proposed access would be limited to data regarding U.S. facilities only and would not require NERC to collect any
additional data. The intent is to inform FERC more quickly, directly and comprehensively about reliability trends or
reliability gaps that might require development of new or modified Reliability Standards. Access to the databases also
would provide FERC with more information to better understand the reliability and adequacy assessments periodically
submitted by NERC.
Comments on today’s Notice of Proposed Rulemaking (NOPR) are due 60 days after publication in the Federal Register.
In other reliability matters, FERC today approved the following items:
•
•
•

R-15-43

A final rule approving Reliability Standard PRC-002-2, which requires the availability of adequate timesynchronized data for post-disturbance analysis (RM15-4-000).
A final rule approving Reliability Standard PRC-005-4, revising the current protection system maintenance
reliability standard to add certain sudden pressure relaying systems (RM15-9-000).
A NOPR proposing to approve Reliability Standard PRC-026-1, to ensure that applicable entities use protective
relay systems that can differentiate between faults and stable power swings (RM15-8-000).
