Exelon: NRG bid may go beyond 2009

Exelon Corp., the biggest U.S. utility owner by market value, said its hostile bid to acquire NRG Energy Inc. may drag on beyond the end of this year.

Chicago-based Exelon continues to look at other energy assets, Chief Executive Officer John Rowe said today at a conference near Houston. "We keep looking, but meanwhile, we just keep working at this one," he said. "We think this is the right one at the right price. We are not changing the price."
