THE Luzon grid went on yellow alert for six hours Tuesday as power reserves thinned.

In an advisory, the National Grid Corp. of the Philippines (NGCP) said the yellow alert on the country’s largest power grid was in effect between 10:00 am to 4:00 p.m. yesterday.

The grid’s available capacity stands at 11,746 megawatts, while peak demand is at 10,831 megawatts, according to the NGCP.

A yellow alert signifies that power supply is approaching critical levels.

The NGCP had not provided details on the alert by deadline time yesterday.

NGCP yesterday reported emergency power interruptions affecting the franchise area of Camarines Sur III Electric Cooperative, Inc. at 3:00 to 5:00 p.m., citing the shutdown of the Naga-Iriga 69 kilovolt (kV) line as requested by Gallintina Inc. for the reconnection of the new Gallintina dressing plant.

Scheduled power interruptions were also expected in parts of Quezon province on June 8, from 8:00 AM to 6:00 PM, due to corrective and maintenance work on the Gumaca-Progreso 69 kV Line and Gumaca-Atimonan 69 kV Line.

Specific areas suffering outages will be determined by the Quezon I Electric Cooperative Inc.

The NGCP also advised of scheduled power interruption in parts of Davao de Oro (Compostela Valley), Davao del Norte, and Davao Oriental, specifically the franchise areas of Davao del Norte Cooperative Inc. and Davao Oriental Electric Cooperative, Inc, on June 15 from 8:00 AM to 6:00 PM. This is due to the repair and maintenance of structures along Maco-Banaybanay 69kV Line.

Specific areas affected will be determined by the electric cooperatives. — — Janina C. Lim
