Operational Context
The Philippines regularly experiences planned electricity interruptions to facilitate grid maintenance, particularly during periods of high demand or infrastructure upgrades. Meralco, as the primary distribution utility in Metro Manila and adjacent provinces, typically publishes feeder-level outage schedules in advance. While these outages are controlled and temporary, their concentration across multiple days can compound operational stress for households, small businesses and essential services, especially in dense urban areas where power reliability underpins transport systems, communications and healthcare delivery.
Executive Summary
- Event Date: 12-18 January
- Location: Philippines (Metro Manila and adjacent provinces)
- Risk Category: Critical Infrastructure
- Severity Level: 3/ 5
- Confidence Score: 75 %
Meralco has announced scheduled rolling power interruptions across parts of Metro Manila and nearby provinces through Sunday, 18 January, to support maintenance and line works. Individual outage blocks are expected to last four to eight hours, with staggered schedules over several days. The overall risk is moderate, primarily affecting small-to-medium enterprises, residential areas and localized transport systems. Advance notice significantly reduces the likelihood of cascading failures, though temporary business disruption, traffic congestion from non-functioning signals and communications degradation remain credible concerns.
Current Updates
Meralco has published feeder-specific advisories covering selected barangays in Manila, Quezon City, Bulacan, Rizal, Cavite and Laguna. Outages are scheduled across both daytime and evening windows, and customers have been advised to secure appliances and plan for medical or safety needs. No major unplanned outages have been reported at the time of advisory issuance, and utility hotlines remain active.
Known Hotspots & Sensitive Zones
- High-impact zones: Densely populated parts of Metro Manila, particularly Manila and Quezon City, where hospitals, transport corridors and commercial districts rely heavily on uninterrupted power.
- Medium-impact areas: Suburban provinces such as Bulacan, Cavite, Rizal and Laguna with mixed residential and industrial loads.
- Low-impact areas: Areas with fewer scheduled feeders or strong generator penetration.
Planned outages are a recurring maintenance feature, with higher sensitivity during periods coinciding with major public events.
Impact on Transportation & Services
Transportation impacts are expected to be indirect, mainly through traffic-signal outages along major corridors such as EDSA, Quezon Avenue and Taft Avenue, leading to localized congestion and increased minor accident risk. Rail systems and public transport may experience delays if operating on backup power. Businesses may face downtime, reduced point-of-sale functionality and temporary loss of internet connectivity, while security systems and CCTV could rely on limited battery reserves.
Recommended Action
- Organizations should activate site-level power contingency plans, test generators and UPS systems, and reschedule critical operations outside outage windows.
- Employers are advised to implement flexible work arrangements and ensure staff safety during outages.
- Coordination with Meralco advisories, local government units, MMDA traffic management and emergency services is recommended.
- Longer-term actions include investment in resilient backup power and clear outage communication protocols.
Multi-Dimensional Impact
The outages overlap with major cultural activities and processions, increasing sensitivity around traffic management and public safety. Reduced lighting and intermittent signal outages could complicate crowd control and emergency response during these events.

Situational Outlook
The most probable outlook is orderly execution of scheduled outages with manageable, short-term disruption. A moderate escalation could occur if switching issues extend outage durations, while severe escalation involving unplanned failures remains a low-probability scenario.
Strategic Takeaway
The scheduled power outages represent a predictable but operationally relevant infrastructure risk. With adequate preparation, most impacts can be mitigated. Businesses and authorities should maintain situational awareness and leverage early-warning and infrastructure-monitoring tools such as MitKat’s Datasurfr to strengthen resilience and continuity planning.
