Often referred to as "the world's largest machine", the U.S. power grid is, in fact, a patchwork system that has been built over the course of the past 120 years. Today, America's grid is split into three independent "Interconnections" known as the Eastern Interconnection, the Western Interconnection and the Texas Interconnection (also known as the Electric Reliability Council of Texas, or ERCOT). For the most part, these Interconnections operate as islands. For example, power generators in the Western Interconnection are only able to sell their power to customers in the Western Interconnection. Renewable energy developers, meanwhile, are facing increasing difficulties in getting sufficient access to the transmission assets required to take their power to market.
By connecting all three Interconnections for the first time ever and offering gigawatts of power transmission capability, the Tres Amigas SuperStation will help break these bottlenecks and help America achieve its aggressive renewable energy goals.
