Constellation Energy announced Tuesday it is accelerating plans to restart Unit 1 of the Three Mile Island nuclear plant by 2027, as mounting power demand and evolving energy policy breathe new life into the once-retired facility. The proposal could make Three Mile Island the first U.S. nuclear plant to resume operations after decommissioning, a powerful symbol amid renewed bipartisan support for nuclear power.
Speaking to reporters and regulators, Constellation CEO Joseph Dominguez emphasized the grid’s growing need for clean baseload electricity, particularly as AI data centers and electrification efforts pressure legacy infrastructure. The company is currently navigating discussions with the Nuclear Regulatory Commission (NRC) to determine licensing and safety pathways for the restart.
Politically, the move comes as both Congress and the White House intensify backing for nuclear energy. The Biden administration’s 2022 Inflation Reduction Act included production tax credits for existing reactors and funds for advanced nuclear development. Meanwhile, Pennsylvania lawmakers have expressed cautious support, seeing potential economic revival through jobs and tax revenue.
Yet the plan faces hurdles. Local opposition remains vocal, especially following recent NRC hearings where residents raised concerns over transparency, waste storage, and long-term safety. Environmental advocacy groups warn that reviving an aging facility with a complicated history demands far stricter oversight than currently proposed.
Still, energy policy analysts note the timing aligns with federal goals to triple nuclear capacity by 2050. A successful restart would deliver over 800 MW of zero-emission power to the PJM Interconnection—key to stabilizing one of the nation’s largest and most strained regional grids.
Constellation has not disclosed investment figures, but experts estimate the effort could run into the billions if infrastructure upgrades and regulatory compliance are factored in.
