Philippine House to Investigate Visayas Power Crisis and Ancillary Charges

Lawmakers to Launch Inquiry into Widespread Blackouts and Costly Grid Fees

MANILA — The Philippine House of Representatives is set to open a formal investigation into the persistent power supply problems plaguing the Visayas region, with a hearing expected as early as next week, according to officials cited in reports by The Manila Times and the Philippine News Agency.

The inquiry will examine both the recurring power shortages that have disrupted daily life and economic activity across the central Philippines, and the ancillary charges imposed on consumers — fees related to maintaining grid stability and reserve capacity that critics say have inflated electricity bills without delivering reliable service.

What the Investigation Will Cover

The House probe is expected to focus on two interconnected issues:

• Power supply reliability: The Visayas grid has suffered repeated yellow and red alert warnings in recent years, signaling thin reserve margins and a heightened risk of rotational blackouts.
• Ancillary service charges: These fees, levied to ensure grid stability and backup power, have drawn scrutiny over whether consumers are being charged fairly for services that are not being delivered reliably.

A hearing date is being finalized for next week, according to the Philippine News Agency, suggesting lawmakers intend to move quickly on an issue that affects millions of households and businesses across islands including Cebu, Negros, Panay, Leyte, and Samar.

Background: A Grid Under Strain

The Visayas grid operates as one of the country's three major power networks, alongside Luzon and Mindanao. Unlike Luzon, which benefits from large-scale baseload plants and growing liquefied natural gas capacity, the Visayas relies on a mix of geothermal, coal, diesel, and renewable sources — a combination that has proven vulnerable to plant outages, transmission constraints, and seasonal demand spikes.

The region's power woes are not new. Over the past decade, the Visayas has experienced:

• Frequent yellow alerts, particularly during summer months when demand peaks and hydroelectric output dips.
• Rotational brownouts, forcing businesses to rely on costly generator sets.
• Rising electricity rates, driven in part by the pass-through of ancillary and congestion charges.

These problems have real economic consequences. Cebu and Iloilo, two of the country's fastest-growing metropolitan areas, host major business process outsourcing, manufacturing, and tourism operations — all of which depend on stable, affordable power.

Why Ancillary Charges Are Under the Microscope

Ancillary services — including frequency regulation, voltage support, and contingency reserves — are essential to keeping the grid stable. But the way these services are procured and priced has raised questions:

• Transparency: Are charges being passed on to consumers without adequate justification or competitive bidding?
• Value for money: If consumers pay for reserves and reliability, why do blackouts still occur?
• Cost allocation: Should the burden fall disproportionately on residential consumers, or be shared more equitably across the supply chain?

Lawmakers are likely to press regulators and utilities on these points during the hearing.

Analysis: A Test of Regulatory Oversight

The House investigation carries significant implications beyond the Visayas. It signals growing congressional scrutiny of the energy sector's pricing mechanisms — an area where the Energy Regulatory Commission (ERC) and grid operator NGCP have faced criticism over perceived gaps in enforcement and consumer protection.

If the probe uncovers systemic issues, it could lead to:

1. Legislative reforms tightening oversight of ancillary service contracts.
2. Pressure on the ERC to review and potentially roll back charges.
3. Accelerated investment in grid modernization and new capacity to prevent future shortages.

Conversely, if the hearing devolves into political theater without concrete outcomes, it risks eroding public trust further — a particular concern as the country approaches the 2028 election cycle.

The Bigger Picture: Energy Security as a National Priority

The Visayas probe reflects a broader reality: the Philippines' energy security remains fragile, and regional disparities in supply reliability threaten national competitiveness. As the country pursues ambitious renewable energy targets and grapples with high power costs relative to its ASEAN neighbors, how it manages the Visayas crisis will serve as a test case for the entire archipelago.

What's Next

The House hearing is expected next week, with energy officials, regulators, and distribution utilities likely to be summoned. Stakeholders — including consumer groups and industry associations — will be watching closely for signals on whether this inquiry produces meaningful reform or merely adds to the pile of unfinished energy policy debates.

For the millions of Filipinos in the Visayas who have grown accustomed to living with unreliable power, the stakes could hardly be higher.
