New Mexico 'Super Station' aims to 'break the power gridlock'

By any yardstick, it's an ambitious project: allow energy to flow more freely across the nation's three massive power grids, breaking down significant barriers to ramping up alternative energy in the United States. A proposed "Tres Amigas Super Station" in Clovis, N.M., would do just that, routing energy from isolated wind and solar installations to urban centers and other places that consume the most power. The transmission hub would be located across 22 square miles in eastern New Mexico near the Texas border. Clovis was chosen because it is nearest to where the nation's three power grids — called the East, West and Texas interconnections — come closest together. Tres Amigas would build a triangular pathway of underground superconductor pipelines, combined with AC/DC converters that synchronize the flow of power between the interconnections. The equipment allows electricity to be transferred from grid to grid. Construction could begin in 2011 or 2012, and the hub could be running in 2013 or 2014, said Phil Harris, chief executive of the Santa Fe-based Tres Amigas. The pipelines, 3 feet in diameter, contain hair-thin ceramic fibers developed by Devens, Mass.-based American Superconductor and can carry enough electricity to power 2.5 million homes...read more
