Power consumers across Luzon, the Visayas, and Mindanao grids should expect higher transmission charge to be reflected in their August 2026 electricity bills.
In a statement, the National Grid Corporation of the Philippines (NGCP) said the transmission rate for the July 2026 billing period to be billed by distribution utilities and electric cooperatives this month increased by 22.22% to P1.7560 per kilowatt-hour (kWh), up from the prior month’s P1.4367 per kWh.
The NGCP attributed the increase in the overall transmission charge due to “sharp increase” in ancillary services (AS) rates.
In particular, AS rates — pass-through costs for power supplied by power generators who provide ancillary services during supply-demand imbalance — increased by 30.85%, from P0.7941 per kWh in June to P1.0391 per kWh in the July billing period.
