Transmission and grid operator National Grid Corp. of the Philippines is suspending all maintenance activities beginning May 5, 2025, in line with contingency plans set by the Commission on Elections for the upcoming national and local elections on May 12.
Based on the updated power outlook, NGCP also said there is also sufficient supply on the critical election weeks. Maintenance activities of power plants were also adjusted to ensure their availability during this period.
“NGCP is strictly following its contingency measures and coordinating with concerned groups to ensure a power interruption-free election, especially during the crucial periods prescribed by the Comelec,” said NGCP.
Construction and non-critical maintenance activities near substations and transmission lines are temporarily suspended from May 5 to 16, 2025.
NGCP said maintenance works and construction activities inside substations and within 300 meters of energized power lines are also suspended.
Meanwhile, all transmission lines were cleared of vegetation and obstructions as of April 30, except for one line in South Luzon. Scheduled vegetation trimming along the said line is still being negotiated with the uncooperative landowner.
These contingency measures were set by NGCP to be consistent with the timeline of activities set by the Comelec in its Resolution No. 10999 dated May 24, 2024 prescribing the calendar of activities and prohibited acts in line with the national elections, and Resolution No. 11055 dated September 13, 2024 setting the roles of different agencies in ensuring the peaceful and credible conduct of the mid-term elections.
Local absentee voting started on April 28, 2025, while canvassing and proclamation of winners are set from May 13 to 19, 2025.
NGCP said uninterrupted and reliable transmission of power must be ensured during this critical period, thus warranting maintenance works and shutdowns to be put on hold.
NGCP said it will activate the 24/7 operations of its Overall Command Center from May 11 until 8 PM of May 14, 2025, and its critical units, particularly system operations (SO) and operations and maintenance (O&M), will remain fully staffed and operational.
Line crews, engineers, pilots, maintenance and testing, and other technical personnel are also strategically positioned in substations to respond to line trippings, if any. Administrative and other support teams will also remain on duty.
As early as February, NGCP’s Power Task Force Elections (PTFE), a special team formed to ensure the security and reliability of the transmission network across the country during the elections, already set out with preparatory activities.
