Exelon won't up NRG offer, CEO says

Exelon Corp., the biggest U.S. utility owner, has "no intention" of raising its $5.13 billion offer for power producer NRG Energy Inc. short of a negotiated deal that follows a due diligence review, Chief Executive Officer John Rowe said.

Exelon was "ecstatic" that more than 51 percent of NRG shareholders accepted its offer as of Feb. 25, Rowe said today at an analyst conference in Philadelphia. NRG's board has continued to dismiss the offer as insufficient, Rowe said.

Exelon is the largest U.S. producer of electricity from nuclear energy, and owns power utilities in Philadelphia and Chicago.
