TRENTON - (AP) - Chicago-based electricity company Exelonconfirms it will close the nation's oldest nuclear power plant in2019 - 10 years earlier than planned - but will not have to buildcostly cooling towers for it.

Exelon Corp. says changing markets and upkeep costs for NewJersey's Oyster Creek Nuclear Generating Station have caused itsvalue to decline.

The aging plant is in the Forked River section of LaceyTownship, 60 miles east of Philadelphia and 75 miles south of NewYork City. It won't be required to build one or more cooling towersto replace its current technology, which draws 1.4 billion gallonsof water a day from Barnegat Bay, killing billions of aquaticcreatures each year.

Oyster Creek went online Dec. 1, 1969. It provides 9 percent ofNew Jersey's electricity.
