5 August 2010– Edison International said installing required emission control systems at six Illinois coal-fired power plants could cost a maximum of $1.2 billion, according to an article on the Wall Street Journal’s website.

The company’s Midwest Generation unit, which operates six coal-fired power plants in Illinois, must cut mercury, nitrogen oxide, sulfur oxide and particulate emissions at the plants as part of an agreement with the state. The company has already installed equipment to cut mercury emissions and received state approval to install equipment to cut nitrogen oxide emissions.

Midwest Generation will use a technology that uses dry sodium sorbent to reduce the sulfur dioxide emissions, but it is unknown how many plants it will be installed in. If the company installed the equipment at all six plants it would cost about $1.2 billion.
