Ancillary services push transmission rates up in July 2026 electric bills
Power consumers may see a slight increase in transmission rates reflected in their July 2026 electricity bills due to an increase in ancillary service (AS) rates.
Overall, the equivalent average transmission rate for the June 2026 billing period to be billed by distribution utilities and electric cooperatives this July increased by 0.77% to PhP1.4604/kWh, up from May’s PhP1.4492/kWh.
AS rates – pass-through costs for power supplied by power generators who are AS providers during supply-demand imbalance – increased by 10.18%, from PhP 0.7220/kWh in May to PhP0.7955/kWh in June.
NGCP emphasized that it does not earn from AS and does not benefit from any change in AS prices, as these are remitted directly to generation companies with bilateral contracts with NGCP, and to the Independent Electricity Market Operator of the Philippines (IEMOP) for AS sourced from the Reserve Market.
Meanwhile, NGCP’s transmission wheeling rate, or the fee for delivering power through the transmission grid decreased to PhP0.5058/kWh in June from PhP 0.5607/kWh in May.
NGCP reiterates that bulk of the overall transmission rate still comprises of charges for Ancillary Services.
“As the system operator, NGCP’s priority is to ensure the grid remains resilient during supply-demand imbalances. NGCP does not profit from AS charges, as these are remitted directly to the providers who help us maintain the continuous flow of electricity across the country,” NGCP said
