Illinois' six nuclear power stations will receive the bulk of a $5 billion federal investment to expand electricity production. The funding came as the state faced a possible energy shortfall in 2028.
Here's what to know
On Oct. 27, the U.S. Department of Energy announced grants to modernize eight nuclear power stations across three states, according to WMBD. Li Arellano, a state Senator whose district includes northern Peoria, Illinois, said the work would generate enough additional electricity to supply one million homes.
Of the eight facilities receiving funds, six were located in Illinois, including the Quad Cities, LaSalle, Dresden, Clinton, Byron, and Braidwood clean energy centers. The other two recipients were Maryland's Calvert Cliffs Clean Energy Center and Pennsylvania's Limerick Clean Energy Center.
More background
The push to expand electricity production in Illinois followed a warning from the 2025 Adequacy Resource Study, which was a joint product of the Illinois Commerce Commission, Illinois Power Agency, and Illinois Environmental Protection Agency, according to WMBD. The study found that the state's power production could fail to meet demand within just a few years.
Illinois' six nuclear stations have 11 reactors altogether. Clinton has one reactor, while each of the other five stations has two. Together, they provide a substantial fleet for the nuclear modernization effort, helping to avoid the years of planning and construction it can take to build a new nuclear power facility.
"In addition to the more power that this might have in long-term impact, it might create jobs, lots of great union jobs, [and] it might bring a lot of worldwide economy into Illinois," Arellano said, per WMBD.

What's being done?
In addition to backing the modernization of nuclear facilities, some lawmakers have been pushing to lift Illinois' ban on building new nuclear reactors. That effort has been led in large part by state Sen. Sue Rezin, according to WMBD.
Illinois' long-term energy needs could be met in part through nuclear investment, Rezin has argued, though projects require considerable time before they begin operating.
"At a time when electricity demand is skyrocketing, and families are already struggling with rising utility costs, expanding our existing nuclear facilities is exactly the kind of investment we need," Rezin said, per WMBD.
While nuclear plants can produce large amounts of low-carbon electricity and support a reliable power grid, they also come with high upfront costs, safety concerns, and the need to manage the radioactive waste they produce. However, nuclear advocates continue to voice their belief that the benefits far outweigh the costs.
"Illinois is at the center of America's nuclear energy future, and investments like this are going to help keep it that way," Rezin said, per WMBD.
