First Gen-owned power plants have resumed operations, enhancing the Luzon grid’s power supply for the summer after components of its switchyard suffered damages.

Restoration work on the San Lorenzo Switchyard has been complete, First Gen Corp. said.

“We are pleased to advise that the connection to the grid of the 500-megawatt (MW) San Lorenzo, 414 MW San Gabriel, and 97 MW Avion power plants has been restored. Accordingly, power output from all three power plants can now be exported to the grid,” they said.

The switchyard connects the company’s three natural gas-fired power plants to the National Grid Corporation of the Philippines’ transmission lines.

“We exerted all efforts to enable San Lorenzo, San Gabriel, and Avion to export their outputs at the quickest time. Our site management team and our contractors have worked tirelessly since last week including through the Holy Week,” First Gen vice president Jerome Cainglet said.

The 1,000-MW Sta. Rita power plant resumed operations after assessment showed that the switchyard did not suffer any damages, First Gen earlier announced.

The Luzon grid’s power supply thinned last week after power facilities tripped due to the earthquake that hit Batangas in April 8.

NGCP placed the grid on yellow alert from 9 am to 4 pm, but raised the red alert status from 1 pm to 3 pm after power demand increased during the supply insufficiency.
