TOKYO - Tokyo Electric Power Company Holdings Inc. said Friday it will restart a reactor at a nuclear power plant in Niigata Prefecture, northwest of Tokyo, on Monday, after the facility was halted over an alarm incident.

TEPCO also revealed that the start date of commercial operations of the seven-unit Kashiwazaki-Kariwa plant has been pushed back to March 18 from the previously planned Feb. 26, after the company determined that a setup error likely caused the alarm incident.
