What is the purpose of NERC?
The North American Electric Reliability Corporation (NERC) is a not-for-profit international regulatory authority whose mission is to assure the effective and efficient reduction of risks to the reliability and security of the grid.
Who does NERC report to?
Compliance under NERC is authorized by the Federal Energy Regulatory Commission (FERC) through the Federal Power Act. As such, NERC measures compliance activities by monitoring, registering, and certifying organizations that power North America.
Why Tree Trimming (vegetation management) is necessary?
Tree contact with transmission lines is a leading cause of electric power outages and a common cause of past regional blackouts, including the August 2003 blackout that affected 50 million people in the Northeast United States and Canada. Following the 2003 blackout and subsequent federal legislation, the Commission designated the North American Electric Reliability Corporation (NERC) as the Electric Reliability Organization (ERO), with the responsibility to develop and enforce standards to ensure the reliability of the Bulk Power System, including the Reliability Standard that addresses vegetation management covering tree trimming on rights-of-way, FAC-003-4.
