The leader of Illinois' largest utility is appealing to lawmakers’ competitive spirits to get them on board with overhauling energy regulations.

Com-Ed CEO Ann Pramaggiore says many Fortune 500 companies have committed to meeting sustainable energy goals.

As Exelon seeks state help in propping up the Clinton Nuclear Plants and several Illinois reactors, the company's subsidiary, Com-Ed, has pushed for changes to electricity rates.

The idea is to charge customers based not on how much overall electricity they use, but on how much energy a household uses when demand is high.

A group of Chicago politicians have signed on to a letter with organizations including the Illinois Public Interest Research Group, opposing the plan.

Exelon Corp. says it will shut two Illinois nuclear plants after the Illinois Legislature declined to act on its request for financial support. The company said Thursday it will close the Clinton Power Station in Clinton on June 1, 2017, and the Quad Cities Generating Station in Cordova on June 1, 2018.

Governor Rauner says he's not sure whether he can support the legislation introduced last week designed to save the struggling Clinton nuclear power plant.

During an appearance in Bloomington Friday, Rauner said he generally supports nuclear power.

"Nuclear power plants are an important part of our overall energy mix. They're an important source of energy production and I want to make sure we have a broad energy mix in the state of Illinois. And nuclear power generation creates a lot of good paying jobs. I don't want to lose those jobs," Rauner said.

Exelon Nuclear estimates it will lose more than 100 million dollars on its Clinton and Quad Cities Nuclear Power plants in 2017 unless it can get money to preserve those reactors.

The CEO of Commonwealth Edison says the utility is continuing to push for changes that failed to win legislative approval in the spring. Anne Pramaggiore told an audience at the City Club of Chicago that a 20-11 so-called "smart grid" law has led to savings and a more reliable power network. But she says further improvements -- like microgrids that can keep electricity flowing when there's an outage, and charging stations for electric cars -- depends on help from Springfield.
