Illinois passed one of the most aggressive clean energy bills in the country on Monday, in a rousing success for environmental advocates that, unusually, also bails out some of the state’s biggest sources of clean power: nuclear energy. //

Importantly—and unusually for a bill cheered by green groups—the bill also contains a huge bailout for the state’s nuclear industry. It earmarks nearly $700 million in subsidies to prevent the closure of the Byron and Dresden Generating Stations, two of six nuclear plants in the state. Doing so will extend their lifelines by another 5 years. Exelon, the plants’ owners and one of the biggest utilities in the country, had set a deadline of Sept. 13—the day the Climate and Equitable Jobs Act was passed—as the day they’d need to start closing Byron without some help from the state. Doing so would have taken one of the biggest nuclear plants in the country offline. A report from nuclear advocates estimates that Illinois’s six nuclear plants currently provide 90% of the state’s clean power. Some analyses have shown that the plants’ closure would spur coal and gas plants to run more frequently to keep the grid operational, in addition to affecting the thousands of workers at the plants. //

The Illinois bill, on the other hand, clearly ties the nuclear bailouts to new provisions for clean jobs and environmental justice. Green groups like Natural Resources Defense Council and the Sierra Club have both supported the closure of nuclear plants in the past, and the Sierra Club has spoken out against subsidies for nuclear in Illinois. But both groups have cheered the passage of this new bill.

The success in Illinois doesn’t mean nuclear is suddenly on the table for green groups, however. “Illinois needs to transition away from dirty fossil fuels as quickly as possible to fight the climate crisis,” JC Kibbey, a clean energy advocate for NRDC in Illinois, said in an email. “Longer-term, we will transition away from nuclear because wind and solar provide a cheaper, safer and more reliable source of energy.
