Nuclear is enjoying a bit of a resurgence. The momentum for reliable energy to support economic development around the country—specifically data centers and AI—remains strong, and strongly in favor of nuclear. And as feature coverage on the states in the January 2026 issue of Nuclear News made abundantly clear, many states now see nuclear as necessary to support rising electricity demand while maintaining a reliable grid and reaching decarbonization goals.

The Clean and Reliable Grid Affordability Act (CRGA)—which Pritzker says is designed to lower energy costs for consumers, drive the development of new energy resources in the state, and strengthen the grid—lifts the moratorium on new, large nuclear reactors that Illinois enacted in the late 1980s.
