Exelon Generation announced yesterday that it is investing more than $300 million in capital projects at its Byron and Dresden nuclear plants in Illinois over the next five years and filling some 650 vacant positions across the state.

These actions are in response to Illinois Gov. J.B. Pritzker’s recent signing of S.B. 2408, the hard-won legislation that rescued the nuclear facilities from premature retirement.

“With this landmark legislation in place, we are moving quickly to restaff and refuel all of our nuclear plants for 24/7 operation, producing carbon-free, baseload electricity for more than 10 million homes and businesses,” said Dave Rhoades, Exelon Generation’s chief nuclear officer. “These plants are not only important for the clean energy they produce, but they are massive economic engines for their local communities, contributing more than $1.6 billion to Illinois’s GDP each year.”

Planned projects: Exelon said it plans to invest more than $140 million in projects at Byron—which began its fall refueling outage following the passage of S.B. 2408—including overhauling a main generator, replacing large transformers, upgrading a fiber optic control system, and replacing various pumps, motors, and piping in the plant. Most of the projects will be carried out during refueling outages starting next year and will include more than 1,500 electricians, pipe fitters, welders, carpenters, and other tradespeople, according to Exelon.

Nearly $170 million in capital projects are planned for Dresden, including upgrades to six feedwater heat exchange vessels, significant refurbishment of a main generator, electrical component overhauls, replacement of closed cooling piping, and the revamping of nuclear instrumentation circuit components.

In its announcement, Exelon encouraged those interested in applying for positions with the company to visit the careers page on and search for “nuclear.”
