In April 2009, Ameren suspended efforts to build a proposed new nuclear power plant, the "Callaway 2," in Missouri. It was "the first of the '[[nuclear renaissance]]' reactors to fall by the wayside," reported the ''New York Times''. The move came after Ameren stopped efforts to change Missouri state law to allow "[[construction work in progress]]" (CWIP). CWIP allows utilities to charge customers to cover the cost of future electricity, and has been used to help fund expensive nuclear reactor projects. <ref name="Call2">Matthew L.

However, a [[Nuclear Regulatory Commission]] spokesperson "hinted that AmerenUE's application might not, in fact, be dead," as "AmerenUE had been in contact with the commission staff this week, and had not asked that the commission staff stop work on the application. That work is done at the expense of the applicant." <ref name="Call2"/>
