South Texas 2 reactor to return by mid-April

 HOUSTON, March 1 (Reuters) - The 1,280-megawatt Unit 2
at the South Texas Project nuclear station in Texas is expected
to be back in service by mid-April, well before the state's peak
electric demand, NRG Energy officials told investors this week. 	
 The unit has been shut since Nov. 29, when the main
generator malfunctioned due to a ground fault that resulted in
damage to rotor and stator coils, South Texas Nuclear Operating
Co officials said previously. 	
 The 72 coils have been replaced and the damaged rotor is
being refurbished at a Siemens facility in North Carolina.
 The Texas grid agency and regulators are watching the
state's generating supply after a heatwave in 2011 sent electric
demand soaring, straining resources. The grid operator was
forced to curtail power to some industrial customers on certain
days, but avoided rolling outages. 	
 The 1,280-MW Unit 1 has continued operating at 	
full power.
