Debate at the commission

Dynegy, which produces more power in MISO’s Illinois territory (Zone 4) than any other energy company, has said that many of its coal-fired power plants are in danger of being shuttered or sold, and it wants Illinois legislators to consider legislation to keep these plants firing.

In April, MISO released new information showing the cost of reserving power plant capacity would be going up, and in May, after Dynegy proposed that Illinois assume capacity pricing, the grid operator wrote a letter to Illinois Governor Bruce Rauner asking state officials to step in, saying the reliability outlook could be “uncertain from year to year.”

In a letter to the commission in advance of the workshop, Dynegy said that the “possible shut down or removal (e.g., sale to other markets) of additional Dynegy generating units poses a serious near-term risk of a capacity deficit in MISO Zone 4.”

It has been 20 years since Illinois began restructuring its energy system, and the commission is no longer part of reliability planning. Rather, energy companies now compete on wholesale and retail markets to ensure that there is enough power to go around during all seasons.
