Superconducting Interconnects For Three Grids

Here's a bit on the Tres Amigas project, which proposes to interconnect the Eastern, Western, and Texas electrical grids with a limited set of superconducting DC lines so the various grids can shed or acquire power from each other. Not only is this an essential technology for dealing with intermittent resources (aka wind and solar) but it's a key test of longer-haul superconducting DC transmission technology.
