    Independent System Operator – While utilities may own their own generating stations and power lines for distributing electricity to their customers, much of the operation of these assets occurs through their participation in a regional transmission organization (RTO), sometimes called an independent system operator (ISO). RTOs operate the transmission grid over a multi-state region on behalf of utilities—ensuring greater system reliability and reducing costs. As part of this process, RTOs “dispatch” power plants to start running as electricity demand increases, and they stop the plants when demand decreases. Typically, RTOs dispatch plants based on cost (lowest cost first), regardless of where in the multi-state region they may be located. As a result, overall cost and emissions implications can be complex, and may take little account of state borders.

    Western Electricity Coordinating Council

    The Western Electricity Coordinating Council (WECC) is a non-profit corporation that exists to assure a reliable Bulk Electric System in the geographic area known as the Western Interconnection. WECC has been approved by the Federal Energy Regulatory Commission (FERC) as the Regional Entity for the Western Interconnection. The North American Electric Reliability Corporation (NERC) delegated some of its authority to create, monitor, and enforce reliability standards to WECC through a Delegation Agreement.

    WECC was formed on April 18, 2002, by the merger of the Western Systems Coordinating Council (WSCC), and two regional transmission associations. WSCC, WECC’s predecessor organization was organized in August 1967 to facilitate electric industry coordination in the planning and operations of the electric system in Western North America.
