FERC approves revised NERC definition of "bulk electric system"
27 December 2012
The Federal Energy Regulatory Commission (FERC) has issued Order No. 773, which approves a revised definition of "bulk electric system" proposed by the North American Electric Reliability Corporation (NERC) in response to a prior FERC directive. The revised definition establishes a "bright-line" threshold pursuant to which transmission facilities at 100 kilovolts or above must comply with applicable NERC reliability standards. The definition also incorporates designations of types of facility configurations that are specifically included in, or excluded from, the bulk electric system, and abolishes the existing discretion afforded to regional reliability entities to determine which transmission facilities should be subject to compliance with reliability rules.
