Power Grid Operations Back to Normal: NGCP

The National Grid Corporation of the Philippines (NGCP) said transmission lines and facilities nationwide are back to normal operations as of 5 a.m. Tuesday after an outage in a Visayas substation late Monday afternoon.

The issue at the Daanbantayan Substation was caused by the outage of two transformers that are serving the areas being serviced by the Cebu II Electric Cooperative Inc. (CEBECO II).

In an advisory, the NGCP said the facility was re-energized by 2:30 a.m. Tuesday, thus, all transmission lines and facilities around the country are now operating normally.

Relatively, the Department of Energy (DOE) said Unit 1 of the Team Energy Corporation (TEC) power plant in Pagbilao, Quezon is expected to go back online Tueday, May 14, after its forced outage last May 2 due to excessive water leak at feed water flow sensing line.

Also, the Unit 1 of GNPower Mariveles Coal Plant Ltd. Co. (GMPC) in Bataan, which was affected by high turbine vibration, is expected to be resolved as early as May 15, DOE said.

Also, the Energy Department said eight power plants that are currently on de-rated capacity, with the hydroelectric power plants on reduced capacity due to low water levels .

Units 1-4 of SN-Aboitiz Power Inc. (SNAP) Binga Hydroelectric Power Plants are derated by 68 megawatts (MW) and are only producing 70 MW.

Units 1-4 of SNAP’s Magat Hydroelectric Power Plant are producing 70 MW instead of 380 MW and its Ambuklao Hydroelectric Power Plant units 1-3 are only producing 70 MW instead of 105 MW.

Meanwhile, Unit 2 of the SEM-Calaca Power Corporation (SCPC) is running only at 200 MW instead of 300 MW due to half condenser operation; Unit 3 of the Pagbilao Energy Corporation (PEC) is producing only 370 MW since it is undergoing boiler condition assessment simlar to the factor for the deration of SMC Consolidated Power Corporation (SMCCPC) Limay Unit, which is derated to 130 MW.

The DOE said the Silay Solar, which has a 25 MW experienced Outside Management Control, is on forced outage as of 12:35 p.m. Monday due to tripping of the 69 kV line of the Central Negros Electric Cooperative Inc. (CENECO).

“The solar farm will resume operation once the line of CENECO is restored,” it added. (PNA)
