The facilities include Quad Cities in Cordova, Illinois, Dresden in Grundy County, Illinois, and Peach Bottom in York County, Pennsylvania.

Alstom has already begun work on the first project under the agreement, the retrofit replacement of three low pressure steam turbine sections at the Quad Cities power station.

The retrofit equipment for the first project is being manufactured by Alstom in Belfort, France, and Morelia, Mexico, with components for subsequent projects to be manufactured in Chattanooga, Tennessee.

Philippe Joubert, executive vice president and president of Alstom Power Systems, said: We are very pleased to have been selected by Exelon to provide essential technology to upgrade their nuclear steam turbines. As the world’s largest supplier of nuclear turbine systems, we offer both experience and a history of innovation that make us the right partner for Exelon.
