We reached out to two of the companies that will be affected the most by these rules — the businesses that own the state’s coal-fired power plants. NRG Energy, which operates the plants closest to Chicago, did not respond to a request for comment. A spokesman for Dygeny Inc., which operates 10 coal-fired plants downstate, said: “We are continuing to study this rule.” Part of the reason the company hasn’t weighed in yet, he says, is that Dygeny did not receive an advanced copy of the rules, which are 1,560 pages long. One group that knows where it stands on what the president announced this week is the Illinois Manufacturers’ Association. The group’s vice president and COO Mark Denzler join us.
