The U.S. electric grid is facing a triple threat of rising rates, rapid demand growth, and increasing reliability risks. These issues have wide ranging impacts on the future of America’s economic growth, industrial competitiveness, and national defense. Meanwhile, there remain challenges to quickly bring enough power generation online to meet these threats and ensure the lights stay on. In recent years, adding new generation capacity has been hindered by long interconnection queue delays and supply chain disruptions. Surplus Interconnection Service (SIS), which allows new energy resources to connect to the grid using existing plant interconnections, can in many cases offer a solution to these problems and economically accelerate energy deployment to enhance grid reliability.
