Tres Amigas SuperStation
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. In 2015, the project lost access to the Eastern Interconnection (72% of its total peak demand) when Southwestern Public Service dropped out.
