Southwest Luzon Power Generation Corp. said Friday it is extending the unplanned outage of its Unit 1 coal-fired power plant, with a dependable capacity of 140 megawatts, lower than its installed capacity by 10 MW.
The outage happened on 17 June, reducing the amount of available electricity in the Luzon Grid.
“The plant outage was caused by turbine tripping, which resulted from high axial displacement—an excessive movement of the turbine along its spinning axis,” said the company.
SLPGC’s power complex has two units of coal-fired generators, each with a dependable capacity of 140 megawatts. The power plant started commercial operation in 2016, and contributes around 280 MW of dependable capacity to the Luzon Grid.
SLPGC said managers at its power plant, located in Calaca, Batangas, are still investigating the cause of the excessive turbine movement, including a detailed inspection of the turbine component.
“Repair work and return to service are targeted before the end of August,” it said.
The insurance brokers and adjusters of SLPGC have been informed of the matter and are currently working with plant management to process the filing of the insurance claims.
Coordination with power industry regulators and other key stakeholders are likewise underway.
