It's nice to find
an energy company
that can also keep you
feeling good.

   FPL Group is joining forces with Constellation Energy to form a "new Constellation Energy," one that will be the nation's leading electricity provider and add another name to Maryland's list of Fortune 100 companies. In addition to being one of America's cleanest electric companies, FPL Group is also the global leader in generating electricity from wind and solar energy.


   FPL Group is dedicated to environmental stewardship while providing customers with highly reliable service at the lowest

  

possible cost. Maybe that's why Fortune Magazine named FPL Group among the most admired utilities in the U.S. and why this powerful combination is the right one for Maryland and its many communities.
