Visayas braces for tight power supply during evening peak hours

AMID the energy crisis brought about by the Middle East war, electricity customers may experience relief, following the announcement of the Energy Regulatory Commission to suspend the collection of a renewable energy charge on electricity bills, a move that is expected to reduce electricity rates by about P0.03 per kilowatt-hour or P6 in monthly savings for households consuming an average of 200 kilowatt-hours.

The Visayas grid is expected to operate on thin power reserves during evening peak hours after the National Grid Corp. of the Philippines (NGCP) placed the grid under yellow alert from 5 p.m. to 9 p.m.

In an advisory this morning, NGCP said available capacity for the Visayas grid was projected at 2,580 megawatts (MW), while peak demand was expected to reach 2,423 MW.

Visayas grid under yellow alert as power plant outages mount

A yellow alert is declared when the operating margin is insufficient to meet the transmission grid’s contingency requirement, signaling a tight power supply situation although no power interruption has been declared.

NGCP said the alert, raised for the second straight day, was triggered by forced outages at several power plants and high electricity demand during evening hours.

Among the plants currently offline are TVI Unit 1 with a capacity of 169 MW, TVI Unit 2 with another 169 MW, and PEDC Unit 3 with 150 MW.

The grid operator added that 20 power plants remain on forced outage, including 11 plants that have been offline since March 2026, four since 2025, two since 2024, two since 2023, and one plant that has been unavailable since 2021.

Meanwhile, 12 other power plants are operating on derated capacities, leaving a total of 857.2 MW unavailable to the grid.

Electricity demand in the Visayas typically rises during the evening as households and businesses simultaneously use more power, putting pressure on available reserves.
