Dynegy Inc. continued to urge state regulators in Illinois for action to support eight of its coal-fired power plants in the state that sell into the Midcontinent ISO market.

The competitive generator in reply comments dated Dec. 21 urged the Illinois Commerce Commission to address resource adequacy in MISO Zone 4, which covers central and southern Illinois and the service territory of distribution utility Ameren Illinois Co., a subsidiary of Ameren Corp. The comments were filed in response to a workshop that the ICC held on Dec. 7 where MISO, Dynegy and various stakeholders discussed whether market prices are adequate to ensure long-term supply. Dynegy, the largest coal generator in Illinois, owning 11 plants in the state, indicated in the comments that market conditions including slack demand growth and lower wholesale power prices have placed eight of its plants at risk of shutdown.
