Tres Amigas SuperStation (2009-2016)
A proposed 5-gigawatt hub in Clovis, New Mexico, that would have connected all three U.S. interconnections. It was announced with fanfare in 2009 but never secured the funding or regulatory approvals to be built.
The project stalled and was eventually abandoned.
It showed how difficult interconnecting the U.S. grids is, both technically and financially.
Three Corners Connector faces the same challenge of linking the eastern and western grids, but with a more focused scope: a single point-to-point line rather than a multi-hub superstation.
