Bulk Electric System Reliability Evaluation

Dates & Locations



    The US Energy Policy Act of 2005 required that mandatory and enforceable reliability standards be developed and enforced by an Electric Reliability Organization (ERO) under the Federal Energy Regulatory Commission (FERC). The ERO, formed by the North American Electric Reliability Corporation (NERC), issued 107 reliability standards, 83 of which were accepted by FERC. Some of these standards deal with the Bulk Electric System (BES) reliability evaluation. This course provides the background necessary to understand the methods and tools for the BES reliability evaluation.
