Governor Pritzker Backs Full Nuclear Moratorium Lift Amid Surging Energy Needs

Illinois Governor J.B. Pritzker has signaled a significant shift in his stance on nuclear power, now expressing support for lifting the state's decades-old moratorium on the construction of large nuclear plants. This reversal comes amidst growing concerns over high energy costs and increasing demand, particularly from energy-intensive sectors like artificial intelligence and data centers. The governor's recent remarks indicate a departure from his previous position, where he had vetoed similar legislation.

In 2023, Governor Pritzker vetoed a bill that aimed to completely lift the nuclear construction moratorium, citing concerns about the potential for "exorbitant ratepayer-funded bailouts" and insufficient regulatory protections for large-scale reactors. Subsequently, he signed a modified bill that only permitted the construction of smaller nuclear reactors, specifically those generating 300 megawatts or less. This partial lift was seen as a cautious step towards embracing advanced nuclear technologies like Small Modular Reactors (SMRs).

However, the governor's recent comments suggest a broader acceptance of nuclear energy's role in the state's future. "When asked about high energy costs at the Illinois State Fair Wednesday, the governor said Illinois could do something important by lifting the decades-old moratorium," stated a recent social media post by James Hopf. This statement is particularly notable given Pritzker's earlier economic arguments against large reactor construction.

The change in position is largely attributed to evolving market conditions and a nationwide increase in support for nuclear power. State Senator Sue Rezin (R-Morris), a long-time advocate for expanding nuclear energy, has emphasized the need for reliable baseload power to meet rising demand. Illinois, already the leading nuclear energy producer in the U.S. with 11 reactors, faces projections of energy demand outstripping supply by 2030, driven by the rapid expansion of data centers and AI infrastructure.

While proponents argue that nuclear power offers a carbon-free and stable energy source crucial for the state's clean energy goals, environmental groups maintain reservations. Organizations like the Illinois Sierra Club have voiced concerns regarding the high costs of new nuclear construction, the unresolved issue of radioactive waste disposal, and potential safety implications. They advocate for prioritizing renewable energy sources like wind and solar, which they argue are more cost-effective and quicker to deploy.

Despite the ongoing debate, the governor's latest comments could pave the way for new legislative efforts to fully repeal the ban on large nuclear reactors. Senator Rezin has already introduced bills aimed at streamlining permitting processes and allowing for broader nuclear development. The long lead times involved in nuclear plant construction, often 10 to 15 years, underscore the urgency felt by some lawmakers to act now to secure future energy supply and attract further economic investment to Illinois.
