CHICAGO — Exelon, the largest U.S. producer of nuclear power, said it will quit the U.S. Chamber of Commerce because the business group opposes federal climate-change legislation, the third utility to do so.
Exelon will not renew its membership in the Washington-based chamber, chief executive John Rowe said Monday at a conference sponsored by the American Council for an Energy-Efficient Economy. California’s Pacific Gas & Electric and New Mexico’s PNM Resources announced similar plans last week.
Congress is working on legislation that would limit fossil-fuel emissions blamed for global warming by introducing a cap-and-trade system. Under the measure passed by the House in June, companies with nuclear generators, such as Exelon and Entergy, wouldn’t bear the costs of the emissions that coal and gas plants would, according to New York-based Sanford C. Bernstein & Co. Bloomberg News
