In 2013, utilities invested a record $16.9 billion in new transmission infrastructure to improve reliability and relieve congestion. More than 25 percent of new projects planned through 2019 are designed to carry power generated by new non-hydro renewables. At a Yale Law School Conference on the Environment, Richard Sedano provided a high-level overview of the new transmission environment, including policy and practical issues associated with integrating large-scale renewable power into the U.S. bulk power system. He warns that expanding the transmission infrastructure is not a silver bullet solution. It should be driven by system needs, robust planning, and the thoughtful consideration of public policy objectives.
