The mission of the North American Electric Reliability Corporation (NERC) is to ensure the reliability of the North American bulk power system (BPS). While electric utility companies are responsible for administering the day-to-day operations of the electric grid, regulators such as NERC and the Federal Energy Regulatory Commission (FERC) are charged with the overall responsibility of ensuring reliability and security.
NERC develops and enforces Reliability Standards, annually assesses seasonal and long-term reliability, monitors the bulk power system through system awareness, operates the Electricity Information Sharing and Analysis Center (E-ISAC) and educates, trains and certifies industry personnel. Normal everyday operations of the system are the responsibility of utility owners and operators.
Protecting critical infrastructure
An attack by a disgruntled former employee, ideologically motivated activist, or a criminal could inflict significant damage
Currently, a significant reliability threat to the U.S. grid is associated with squirrels and balloons, and not religiously inspired terrorists. However – and more applicable to grid operators – we have recently seen noteworthy interest in disabling or destroying critical infrastructure. Coordinated attacks can target the grid, and an attack by a disgruntled former employee, ideologically motivated activist, or a criminal stumbling across a “soft target,” could inflict significant damage. With an interconnected grid of over 450,000 miles of high voltage transmission lines (100 kV and higher) and over 55,000 substations (100 kV and larger), the targets of opportunity are endless.
