Crossed Wires: A Salata Institute-Roosevelt Project Study of the Development of Long-Distance Transmission Lines in the U.S.

This study examines the legal and political institutions and the social context within which transmission lines are built in the United States, and the challenges that an aggressive extension of the grid faces. We focus on one aspect of the grid: long-distance transmission lines. Several recent studies (DOE, NREL, Princeton) offer a technical road map for different ways that the U.S. can develop its long-distance electricity transmission system. These studies are the starting point for this inquiry. They lay out a picture of what the future electricity transmission system might be. This study examines how we get there: the process for developing, scrutinizing, and approving long-distance transmission lines. We examine, side-by-side, the regulatory, economic, and social challenges that arise with the development of long-distance transmission lines. The essential lesson of this study is that local communities and the public broadly should be treated as partners in the development of new transmission infrastructure. In tandem with this study, we have explored transmission line developments in four different areas of the country (for more details, see “How Grid Projects Get Stuck”). In all four cases, the marginalization of community and public preferences fueled opposition and delayed the process. We draw lessons from these cases, especially in developing recommendations for how to improve public engagement in the permitting and siting processes.

Politics of Delay

Reducing greenhouse gas emissions (GHGs) and moving to more renewable sources of energy will require a dramatic expansion and reconfiguration of the U.S. electrical grid. This is especially true given that areas of the country with the highest capacity to generate electricity using wind, solar, hydro dams, and other low-GHG sources of electricity are located far from the nation’s industrial and urban centers. Connecting these regions will bring social and political conflict. We often observe these conflicts play out in the development of long-distance transmission lines that cross multiple states and jurisdictions. Today, transmission projects around the country take about 15 years to move from the initial planning stage to project approvals and breaking ground for construction. These timelines are simply too long if the United States wants to meet its climate goals. In this book project, we develop a theory that helps explain this phenomenon, what we call the politics of delay. We draw on insights from political economy, regulatory policy, business incentives, and community engagement to offer a framework that helps explain why different sets of actors engage in the politics of delay and how we can ultimately overcome these dynamics to meet clean energy goals in a timely and just manner.
