Grid Operator and Reliability Body

Organizations that operate electricity transmission systems or set and enforce reliability standards for them, including regional transmission organizations and independent system operators such as ERCOT and PJM Interconnection, the European association of transmission system operators ENTSO-E, and the North American Electric Reliability Corporation as the reliability standards authority. Belongs here: an organization whose core function is operating the electric grid or maintaining its reliability across a defined territory. Does not belong here: a single electric utility that generates and sells power, which this atlas has not yet needed as its own group; a national regulator that oversees grid operators without operating one itself, grouped under Government Agency.
