CONSUMERS will be charged lower electricity rates in October with the slight reduction in overall transmission rates, the National Grid Corporation of the Philippines (NGCP) announced.

“For the October 2025 electric bill of the end consumers, NGCP charges only 59 centavos per kWh (kilowatt-hour) for the delivery of its services,” NGCP said.

Overall average transmission rates for the September 2025 billing period dropped by 1.23% to P1.3998/kWh from August’s PhP1.4171/kWh.

NGCP explained that the decrease was driven by reductions in both transmission wheeling rates and Ancillary Services (AS) rates. Transmission wheeling rates refer to what the NGCP charges for its core service of delivering electricity, while AS rates cover the pass-through costs of services sourced from the Reserve Market and from providers with bilateral contracts with NGCP to stabilize the grid during power supply-demand imbalances.

NGCP does not earn from AS rates, as these are remitted directly to generating companies, and it does not benefit from any movement in their prices.

NGCP’s transmission wheeling rates went down by 0.84%, from PhP0.5970/kWh in the August 2025 billing period to P0.5920/kWh in the September 2025 billing period.

Average AS rates for the September 2025 billing period decreased by 1.70% to P0.6546/kWh, compared to P0.6659/kWh in the August 2025 billing period. (NGCP press release)
