Tres Amigas SuperStation
The Tres Amigas 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. Tres Amigas officials reiterated their plans to connect the eastern and western grids in 2017 even as leases for property intended to construct the project were relinquished that February according to New Mexico's State Land Office. The project subsequently fell silent, and as of 2021 company officials were unreachable. CEO Phillip G. Harris is the former CEO of PJM Interconnection, an East Coast regional transmission organization (RTO). The site of Clovis, New Mexico was chosen to allow the Texas Interconnection to join if desired. Overview The Tres Amigas SuperStation project proposes to tie the East Coast, West Coast and Texas grids together via three 5 GW superconductive high-voltage direct current power transmission lines, which permit a controlled flow of energy while also functionally isolating
