Therma South Inc., Energy Development Corp. plants undergo maintenance

Two more power plants are set to go through maintenance outages this month.

Therma South Inc.’s 150-megawatt (MW) unit of its 300-MW Davao baseload power plant began its 17-day outage this week for preventative maintenance.

The 77-MW unit of Energy Development Corp.’s Malitbog power plant had a “flashover” inside its high voltage terminal box last week, causing the plant to trip.

“On Aug. 17, 2016, the 77-MW Malitbog unit 2 power plant experienced a flashover inside the high voltage terminal box, which caused Malitbog unit 2 to trip at around 5 p.m. on that day,” EDC said in a disclosure to the Philippine Stock Exchange.

EDC said that Malitbog 2 was offline and was undergoing testing and commissioning of its automatic voltage regulator as a part of its 30 – day scheduled maintenance outage.

“The incident did not have any impact on the grid as Malitbog unit 2 was not synchronized to the grid at that time, and no injuries were sustained by any of the personnel involved,” the company said.

Meanwhile, the maintenance activity for Therma South Inc.’s power plant is expected to be completed by September 7.

“This maintenance activity is necessary to review unit 1 and to implement some corrective measures as needed which should be similar in nature to the coverage of work done in the recently planned outage of unit 2 from June 18 to July 13,” Therma South president and chief operating officer Sebastian Lacson said.

Lacson added that after the outage, TSI would be better equipped to “reliably meet the needs of customers.”

“As always, we will try our best to keep the duration of this interruption to a minimum,” he said.

Therma South Inc. is a subsidiary of the Aboitiz Power Corporation.
