The Visayas power grid is facing a severe supply squeeze, marked by a fresh string of red alerts following more than two months of yellow alerts, according to data from the National Grid Corporation of the Philippines (NGCP). These strained power supply warnings are hitting the region during the rainy season and at a time when economic growth has slowed to a six-month low of 2.6 percent, raising serious concerns among industry observers about the Department of Energy’s (DOE) planning efficacy under Energy Secretary Sharon Garin.
Lingering Outages and Grid Vulnerabilities
The root of the current power crisis involves a mounting backlog of forced outages across generation facilities. According to NGCP records, 10 plants were on forced outage as of last weekend. The backlog includes three generating units that have been offline since 2025, two since 2024, two since 2023, and one since 2021.
Interconnected grids that normally serve as a safety net are currently failing to provide adequate support. Mindanao’s surplus is nearly exhausted, while the Luzon grid is operating with minimal reserves. This tight supply environment threatens both system reliability and Wholesale Electricity Spot Market (WESM) prices, which could trigger financial shocks on consumers’ monthly electricity bills.

Regulatory Action on Generation Fuel Costs
Amid consumer frustration over soaring electricity rates, the Energy Regulatory Commission (ERC) is launching a forensic audit on fuel costs passed on to consumers by generation companies (GenCos). ERC Chairperson Francis Juan stated that the audit will cover the six billing months from January 1 to June 30, 2026. This specific window represents the period when generation costs recorded their steepest increases during the height of the Middle East crisis.
The regulatory review will verify whether every peso of fuel charges was computed strictly under approved formulas, adhered to contractual caps or collars, and reflected actual fuel expenses rather than unauthorized markups. If the audit uncovers excess collections through over-recoveries, those amounts must be refunded to customers via monthly electric bills.
Expert Insight: Sustained yellow and red alerts signal a power system running on razor-thin margins where reserves cannot absorb plant failures. Without strict regulatory oversight on fuel costs and more disciplined generation planning, consumers remain financially vulnerable to market price spikes.
Frequently Asked Questions
What is the difference between a yellow alert and a red alert?
According to operating definitions, a yellow alert means the power system has enough capacity to meet immediate demand but lacks sufficient reserves to absorb another plant failure. A red alert occurs when available supply can no longer cover demand and required reserves, leaving the grid exposed to potential blackouts if another generating unit trips offline.
Why is the Energy Regulatory Commission auditing GenCos?
The ERC is auditing generation companies to determine if fuel costs passed on to consumers during the January 1 to June 30, 2026 window were fully justified. The audit aims to verify computation accuracy against approved formulas and contractual caps, with any uncovered excess collections slated for customer refunds.
How many generating units have experienced long-term forced outages?
Data from the system operator shows that 10 plants were on forced outage as of last weekend, including units offline since 2021, 2023, 2024, and 2025.
