Peak Reliability (Peak) was formed as a result of the bifurcation of the Western Electricity Coordinating Council (WECC) into a Regional Entity (WECC) and a Reliability Coordinator (Peak). The bifurcation of WECC received final approval from the Federal Energy Regulatory Commission (FERC) on February 12, 2014. Peak, a company wholly independent of WECC performs the Reliability Coordinator function in its RC Area in the Western Interconnection.

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.
