Comparing policy conflict on electricity transmission line sitings

Maintaining the quality and reliability of electricity transmission lines is central to effective energy governance. However, transmission line siting is often a contentious policy decision since permitting and constructing lines may involve private and public property, residents and communities, and localized and national concerns. Yet, policy conflict in transmission siting across cases and over time has remained largely understudied. This article derives and tests hypotheses about policy conflict in the context of transmission lines completed or constructed between 2017 and 2018 in the United States. In exploring the full population of transmission lines, we find that a majority exhibit relatively low and moderate levels of conflict and attention rather than high levels. We further examine a subset of six of these cases that represent a range of conflict and attention intensity. We describe variation in the diversity of actors and frames, advocacy coalitions, and the volume of discourse associated with transmission line siting over time. As problems related to energy governance have become more complex, energy siting disputes are likely to remain a fruitful area for research on policy conflict.
