In recent decades, the U.S. has not been able to construct the volume of high-voltage backbone transmission facilities needed to support the country's move to a 'greener' power system. The inability to build sufficient transmission infrastructure thwarts customer demands for a greener power mix.

In this report, we offer perspectives from a range of transmission experts about where the major roadblocks exist, and the latest regulatory and legal changes that promise to bring greater unity between the divergent federal planning and state siting and permitting processes. These changes provide hope that the U.S. can bridge the gaps that have delayed much-needed upgrades to the transmission system.
