and would retain 4,200 related jobs in those regions. The bill introduces a zero emission standard that would compensate utilities that produce power with no carbon emissions. It would commit $750 million to fund low-income programs, such as providing solar energy to communities along with related job training.

Q: What would it cost consumers?

A: If the bill passes, Exelon and ComEd said residential consumers will pay about 25 cents extra on their monthly bill between 2017 and 2030. If the bill is rejected, they said consumers could pay $1.85 per month due to costs of closing down the two nuclear plants and developing other energy resources. The costs to businesses isn’t known and Exelon and ComEd provided no estimates, saying there’s too much variance in the amount of power each business uses and the energy efficiency programs each participates in.

Q: Why are some groups against the bill?

A: Opponents say if the bill passes, consumers will pay $16.4 billion over the period of the bill. They say the provisions would cost 43,000 jobs from companies that either would move out of Illinois or not choose to locate here. If the bill passes, the study said, it could cost businesses and force them to cut jobs or move out of state. The groups also say that Illinois generates 41 percent more electricity than it consumes and this creates a permanent subsidy for generating facilities that are not needed. It also interferes with the competitive market and will stifle future innovation for new energy in Illinois, they say.

A: Exelon Corp., parent of ComEd and Constellation, has written the bill with the support of the Citizens Utility Board, the Illinois chapter of the Sierra Club and others.
