A coal-fired power plant in Alexandria that has been the center of controversy for decades will close Monday.

The GenOn Power Plant's closing is the result of an agreement between Alexandria officials and Houston-based GenOn Energy.

The plant, which opened in 1949, has recently had to scale back operations as a result of the Clean Air Act. Under a 2008 agreement, GenOn will get back about $32 million the city had held in escrow to use for environmental controls.
