Interregional Renewable Energy Zones

A growing number of studies suggest that fundamental changes in the nation’s power sector have major implications for transmission planning (FERC 2022). The changing landscape suggests, among other things, the need for a concerted reexamination of long-distance interregional transmission solutions. Large, long-distance interregional transmission projects have faced institutional obstacles in the past, however (Homer et al. forthcoming). The purpose of this study is to design and test an approach to interregional transmission that can respond both to the evolving needs of the U.S. power system and to the regulatory questions that states and other authorities must consider when approving new investments in transmission.
