Transmission wheeling rates down, AS charges up in March 2025 Electric Bill of the End-Consumers

Consumers can expect an increase in transmission charges in their March 2025 Electric Bills due to higher Ancillary Services (AS) rates.

Transmission wheeling rates, or what NGCP charges for its primary service of delivering power, has gone down by 3.14%, from PhP0.5422/kWh in January 2025 Billing Period to PhP0.5252/kWh in February 2025 Billing Period.

AS rates for the February 2025 Billing Period increased by 5.05%, with PhP0.6975/kWh compared to PhP0.6640/kWh in January 2025 Billing Period. This cost includes the 2nd tranche of the settlement of the remaining 70% AS cost from the Reserve Market for the March 2024 Billing Period whose recovery was deferred by the ERC.

Ancillary Service charges pertain to the cost for AS sourced from the Reserve Market and those for AS providers with bilateral contracts with NGCP.

“For the March 2025 billing of the end-consumers, NGCP charges only 52 centavos per kWh for the delivery of its services. The bulk of transmission charges is for AS, which is remitted directly to AS providers,” stated the company.

NGCP does not earn from AS and did not benefit from the increase in prices. The AS cost is a pass-through cost, and generating companies benefitted from this increase. AS are support services used to balance and stabilize the grid during power supply-demand imbalance. #
