An equipment problem involving steam to the main turbine at the Palo Verde Nuclear Generating Station in Arizona caused a shutdown of Unit 2, APS Generation said on Friday. The 1,270 MW unit (APS share = 380 MW) performed as designed in this situation and shut down automatically. While all of the equipment operated normally during the shutdown, the details are being investigated and it is expected that the unit will return to service early next week, APS said. Units 1 and 3 continue to operate at full power. In the meantime, APS reported that it has adequate supply to meet its customer needs. “Our reserves are sufficient to meet customer demands during the outage,” said Jim Levine, executive vice president of APS Generation. “Our customers will have the energy they need to keep their homes cool and their lights on.” APS Generation, a subsidiary of Pinnacle West Capital Corp., operates Palo Verde on behalf of the station’s six other owners.
