Electric Reliability

Having a reliable supply of electricity is more than just a convenience. It's a necessity. Our economy—and our way of life—depend on it. For electric companies, maintaining a high level of reliability requires constant commitment.

Today, the North American electric system is comprised of a complex interconnected network of generation, transmission, and distribution systems. The structure of the grid helps to make reliability possible, but what makes it a reality is the coordination in operations of the electric companies that make up this network.

Electric Reliability Organization

The Energy Policy Act of 2005 created the Electric Reliability Organization (ERO), an independent, self-regulating entity that enforces mandatory electric reliability rules on all users, owners, and operators of the nation's transmission system. The Federal Energy Regulatory Commission (FERC) is given oversight authority for the ERO.

In July 2006, FERC certified the North American Electric Reliability Corporation (NERC) as the ERO. In March 2007, FERC approved 83 NERC Reliability Standards, which became the first set of legally enforceable standards for the U.S. bulk power system, effective June 4, 2007. Today NERC oversees eight regional reliability entities and is responsible for establishing and enforcing mandatory reliability standards for the power grid.
