Power transmission service provider NGCP announced a slight reduction in overall transmission rates of the end consumers this October following a reduction in ancillary service and transmission wheeling rates.
Overall average transmission rates for the September 2025 billing period dropped by 1.23% to PhP1.3998/kWh, from August’s PhP1.4171/kWh.
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 PhP0.5920/kWh in the September 2025 billing period.
“For the October 2025 electric bill of the end consumers, NGCP charges only 59 centavos per kWh for the delivery of its services,” NGCP explained, adding that AS still accounts for the bulk of transmission charges.
Average AS rates for the September 2025 billing period decreased by 1.70% to PHP 0.6546/kWh, compared to PhP0.6659/kWh in the August 2025 billing period.

During the same briefing, NGCP Assistant Vice President and head of public relations Atty. Cynthia Alabanza, said NGCP does not gain from the AS since their collections from this fee are capped for the year.
“The only reason we translate it into a month-on-month is so that the consumers can understand why we’re charging. But in reality, we’re revenue capped,” she said
