MANILA, March 17 (PNA) – The first unit of the Mariveles Coal Power Plant, which has an installed capacity of 325.8 megawatts (MW), has no restoration timeline yet after it tripped and brought brownouts to some of the Manila Electric Company’s (Meralco’s) customers on Tuesday.

According to the Department of Energy (DOE) Electric Power Industry Management Bureau Irma Exconde, power plant operator GNPower, has no forecast of its return online yet.

”No timeline yet, when it will be back online,” Exconde told PNA in a text message.

She revealed the water level, to create steam, inside the boiler was above the normal level. It caused the power plant to trip Tuesday which already reached a capacity of 290 MW.

On Monday, the coal plant climbed to its highest level of 180 MW, it further climbed to 240 MW in the afternoon, but had tripped at 290 MW due to the boiler problem.

Some of Meralco’s customers had experienced brownouts Tuesday due to the outage of the Mariveles coal plant.

”The temporary power interruption experienced in some areas from 6:40 PM is not due to supply deficiency. Automatic Load Dropping (ALD) or the unexpected power interruption was experienced due to tripping of GN POWER 1,” Meralco said on its twitter account.

The distribution company said power in the areas is back to normal, after it was restored four minutes later at 6:44 p.m.

On Tuesday, Exconde told reporters that no brownouts will occur as long as there will be no forced power plant outages.

Last Friday, a day before the Malampaya shutdown, two units of Sual went on shutdown and stopped supplying power to the Luzon grid.

But, Sual Unit 2 was restored shortly by Friday evening, while Sual Unit 1 returned early Saturday morning. (PNA)
