History of Nuclear Moratoria

This timeline and 1-pager track the evolution of state-level nuclear construction moratoria, which states have lifted them, and the status of existing restrictions. Beginning in the 1970's, a number of U.S. states adopted restrictions on the construction of nuclear power plants. In the last ten years, nearly half of the states with these moratoria have removed them. Recent repeals reflect a broader shift in policy priorities. As states confront rising electricity demand, decarbonization goals, and the need for clean, firm power, nuclear energy is being reconsidered as part of the solution.
