• The U.S. has three electric grids: Eastern Interconnection, Western Interconnection, and ERCOT (Texas)
• The Tres Amigas “superstation” has been proposed to be built in Clovis, NM to connect the grids and spur development of renewable power that would otherwise be too remote to efficiently reach population centers.
• The substation would be able to carry 5,000 megawatts of electricity – an amount many times greater than current substations and equivalent to the output of 5 nuclear power plants.
• The Tres Amigas substation would use superconducting cable from American Superconductor Corp that is chilled to minus-300 degrees Fahrenheit.
• Public Service Co. of New Mexico has more than 7,000 megawatts of proposed wind generation that could benefit from the project.
