The National Grid Corporation of the Philippines (NGCP) said electricity consumers will pay lower transmission charges in their December 2025 power bills, following a drop in ancillary services (AS) rates.
The NGCP said AS rates fell by 17.6 percent in November to P0.6217 per kilowatt-hour (kWh), from P0.7542 per kWh in October. The AS covers the cost of power supplied by generators to stabilize the grid during supply and demand imbalances.
NGCP stressed that AS costs are pass-through charges and do not go to the company. These payments are directly remitted to generation companies and to the Independent Electricity Market Operator of the Philippines for services sourced from the Reserve Market.
The company also reported a slight decline in its transmission wheeling rate, or the charge for delivering electricity through the grid. This fell by 0.9 percent to P0.5894 per kWh in November, from P0.5953 per kWh in October.
Overall, the average transmission rate for the November 2025 billing period—reflected in December 2025 electricity bills—went down by 10.3 percent to P1.3547 per kWh, from P1.5105 per kWh in October. The NGCP said this will generally help lower power rates nationwide, although the actual impact will vary by distribution utility and electric cooperative.
Amid the decline, NGCP renewed its call for the unbundling of transmission charges so consumers can better understand their electricity bills. The company said much of the recent increase in transmission charges came from AS costs, which are fully passed on to service providers and do not benefit NGCP.
NGCP also clarified that another component, the Feed-in Tariff Allowance, is charged only to customers directly connected to the grid and not to distribution utilities and electric cooperatives.
NGCP said these charges should be clearly separated from transmission wheeling rates, which reflect the company’s actual cost for delivering electricity. The firm operates, maintains, and develops the country’s state-owned power grid.
National level estimates show that electricity alone tends to take more or less three percent of gross household’s income.
The estimates are higher at 7 percent when all forms of energy cost are considered
