Illinois Governor JB Pritzker has signed a major energy reform bill into law aimed at strengthening the state’s power grid amid warnings of future energy shortages.

Senate Bill 25 expands battery storage, lifts Illinois’ ban on new nuclear power plants, and gives regulators more authority to manage energy supply and demand.

Supporters say the law will improve reliability and hold down costs over time, while critics warn new charges tied to battery storage could raise electric bills starting in twenty-thirty.
