CHICAGO (AP) – Dynegy Inc. has announced it will close three of its coal-powered generating plants in southern Illinois that combined generate about 1,834 megawatts of electricity.

Houston-based Dynegy announced Tuesday it will shutter two coal-fired units at its Baldwin Power Station and one coal-fired unit at Newton Power Station over the next year.

About 190 plant jobs will be eliminated as a result, a Dynegy spokesman said.

But the plants indirectly support thousands more jobs and $1 billion in economic activity annually, Dynegy said.

The closures will take place over the next year, Dynegy announced. Last year, the company announced plans to retire its 465-megawatt Wood River station, which is expected to happen next month.

Combined, all the closures account for about 30 percent of downstate capacity.

Dynegy also says an additional 500 megawatts are targeted for shutdown. Last year, Dynegy announced plans to close its 465-megawatt Wood River station by June 1, with a loss of 90 jobs.

Dynegy Inc. on Tuesday reported a loss of $10 million on first-quarter revenues of $1.12 billion.
