Aug 12 (Reuters) - Ameren Energy Resources (AER), the merchant generation business segment of power company Ameren Corp (AEE.N), said it would cut about 84 jobs in Illinois.
The job cuts, 42 percent of a total of 200 positions at three Illinois generating facilities of its subsidiary Ameren Energy Generating Co, will be completed by the end of the first quarter of 2010, the company said.
"Our merchant generation business expects its 2010 non-fuel operations and maintenance spending to be about 5 to 10 percent below the 2008 level," AER's Chief Executive Chuck Naslund said.
The company also said it had eliminated about $1 billion of planned capital expenditures for 2010 through 2013.
Ameren Corp, of St. Louis, owns and operates more than 14,000 megawatts of generating capacity, markets energy commodities, and transmits and distributes electricity and natural gas to customers in Illinois and Missouri.
One megawatt powers about 700 homes in Missouri.
Ameren Corp shares were flat at $26.37 Wednesday afternoon on the New York Stock Exchange. (Reporting by Adveith Nair in Bangalore; Editing by Deepak Kannan)
