The Western Interconnection is a wide area synchronous grid and one of the two major alternating current (AC) power grids in the North American power transmission grid. The other major wide area synchronous grid is the Eastern Interconnection .
All of the electric utilities in the Western Interconnection are electrically tied together during normal system conditions and operate at a synchronized frequency of 60 Hz. The Western Interconnection stretches from Western Canada south to Baja California in Mexico, reaching eastward over the Rockies to the Great Plains. The USA part has 250 ...

The Tres Amigas SuperStation (lit. ' Three Friends SuperStation ') was a project proposed in 2009 to unite North America’s two major power grids (the Eastern Interconnection and the Western Interconnection) and one of its three minor grids (the Texas Interconnection), with the goals of enabling faster adoption of renewable energy and increasing the reliability of the U.S. grid.

The Western Electricity Coordinating Council (WECC) promotes Bulk Electric System (BES) reliability for the entire Western Interconnection system. WECC is the Regional Entity responsible for compliance monitoring and enforcement. In addition, WECC provides an environment for the development of Reliability Standards and the coordination of the ...
In 2007, Mexico exported 1.3 TWh of electricity to the United States, while importing 0.6 TWh. [4] Companies have built power plants near the United States - Mexico border with the aim of exporting generation to the United States. There are also plans to connect Mexico with Guatemala and Belize as part of the Central American Interconnection ...
Pacific Intertie transmission routes A dual-circuit 500 kV line forming a part of the connection between Path 66 and Path 15.. California Oregon Intertie (COI), identified as Path 66 by Western Electricity Coordinating Council (WECC), is a corridor of three roughly parallel 500 kV alternating current power lines connecting the electric grids of Oregon and California.
On August 10, 1996, the western electric grid experienced another massive blackout. [6] Bonneville Power Administration had failed to adequately clear their right-of-way, and multiple lines arced to nearby vegetation. [2]: 47 At 2:06 p.m., the Big Eddy-Ostrander line flashed and grounded to a tree. At 2:52 p.m., the John Day–Marion line (also ...
