The Power Policy of Maine offers an in-depth exploration of the legal and political history surrounding Maine's hydroelectric power development, contextualized within the broader framework of New England's regional energy policies. Emerging from the author's doctoral research, this study delves into the constitutional and administrative dimensions of power policy, particularly as they relate to the interpretation and application of the Fernald law. While primarily a historical and policy-focused analysis, the work acknowledges the significant economic implications of these policies, which remain ripe for further investigation. This study provides a nuanced examination of the interplay between state-level initiatives and regional energy strategies, offering valuable insights into the complexities of power policy in a region marked by interdependent economic and natural resources. It sheds light on how legal frameworks and judicial decisions have shaped the administration of hydroelectric power, contributing to ongoing debates about resource management, state sovereignty, and regional collaboration. For scholars of political science, environmental law, and regional planning, this work represents a vital contribution to understanding the intersection of energy policy and governance in New England.
