Pennsylvania considers reviving nuclear power to boost grid reliability

Pennsylvania is considering reviving the Three Mile Island nuclear power plant to address growing electricity demands and grid reliability issues. As the state is part of the PJM grid, which serves 65 million people, there is increasing concern about how to meet future energy needs. Rep. Tom Mehaffie emphasized the urgency of the situation, noting that the demand for electricity is rising due to technological advancements and the expansion of data centers and cryptocurrency mining. Experts predict a significant increase in global nuclear power capacity by 2050, driven by technological advancements and a push for carbon-free energy sources. Mehaffie argues that reopening Three Mile Island could provide a quicker solution to energy needs compared to building new gas generation plants. The plant could generate 800-900 megawatts, which is crucial for maintaining grid stability in the coming years. Despite the focus on renewable energy sources like solar power, which currently contributes less than 1% of Pennsylvania's energy production, nuclear power remains a vital component of the state's energy strategy. In 2022, nuclear energy accounted for 32% of the state's energy mix, and Governor Josh Shapiro has proposed a target of 35% clean energy. The challenges of energy production in Pennsylvania are compounded by a lack of cohesive policies among states and the complexities of energy project approvals. Mehaffie warns that without immediate action to enhance energy production, the state could face serious grid issues, highlighting the need for proactive measures to ensure a reliable electricity supply.
