The Three Mile Island nuclear power plant, which has been dormant since 2019, is set to restart its Unit 1 by 2028, marking a significant turning point for nuclear energy in the United States. Constellation Energy, which has owned the plant since 2022, plans to supply power to Microsoft, which has committed to purchasing electricity from the facility for the next 20 years at a price of $110-$115 per megawatt-hour, nearly double the regional standard. The estimated cost of the restart is around $1.6 billion, and it is projected to create approximately 3,400 jobs in the region [cc6498df][45e5f273].
Unit 1 of the plant is expected to generate 835 megawatts of carbon-free electricity, contributing to the growing demand for clean energy. This demand is projected to surge by 40% by 2039, driven by the rise of data centers and electric vehicles as well as the increasing urgency of climate change initiatives. However, concerns linger due to the infamous 1979 accident at the plant, which has led to heightened scrutiny from the Nuclear Regulatory Commission (NRC). The NRC will monitor the restart process closely, and Constellation plans to file an exemption request in November 2024 to facilitate the restart [cc6498df][45e5f273].
In a twist, a group of veteran community activists has announced plans for legal action to block the reopening of the Three Mile Island plant, reflecting ongoing public apprehension regarding nuclear energy [910eef51]. The plant will be renamed the Crane Clean Energy Center as part of its revitalization effort. This development reflects the increasing influence of Big Tech in the energy sector, as companies like Microsoft seek reliable and sustainable power sources to meet their operational needs. The PJM Interconnection has also warned of potential grid reliability issues, emphasizing the importance of integrating new energy sources into the existing infrastructure [cc6498df].
In conjunction with the efforts in Wyoming, where Bill Gates' TerraPower is working on a new generation of nuclear reactors, the restart of Three Mile Island signifies a broader trend towards revitalizing nuclear energy in the U.S. Both projects highlight the potential of nuclear power to play a crucial role in reducing greenhouse gas emissions and meeting the rising demand for electricity driven by technological advancements and climate initiatives [ba55dccc][23f7e4f2]. Additionally, the U.S. Department of Energy is currently reviewing $65 billion in loan requests for new reactors, and Constellation may seek a federal loan guarantee for TMI's restart [910eef51]. Pennsylvania Governor Josh Shapiro has expressed support for fast-tracking the plant's grid interconnection, further indicating the state's commitment to the nuclear revival [910eef51].
Dr. Sama Bilbao y Leon has noted an increased openness to discussions about nuclear energy since 1999, with 28 countries pledging to triple their nuclear capacity by 2050 at recent climate talks. This shift in perception reflects a broader change in the risk-benefit analysis of nuclear energy as climate change concerns grow. Small modular reactors are also being considered as a solution to address cost and timeline issues in nuclear projects, highlighting the need for government efficiency improvements in project permitting [45e5f273].
