Consumers can expect slightly lower electricity bills this June after the National Grid Corporation of the Philippines (NGCP) announced a reduction in transmission charges.
NGCP said the overall average transmission rate for the May 2026 billing period dropped by 9.33 percent to P1.4492 per kilowatt-hour (kWh), down from P1.5983 per kWh in April. The lower rate will be reflected in June electric bills.
The decrease was driven by reduced transmission wheeling charges and ancillary services (AS) costs.
Transmission wheeling rates, which cover NGCP's core service of delivering electricity through the grid, fell by 6.99 percent to P0.5607 per kWh from P0.6028 per kWh in the previous billing period.

Ancillary services rates, meanwhile, declined by 10.73 percent to P0.7220 per kWh from P0.8088 per kWh. These charges cover the cost of reserve power used to stabilize the grid during supply and demand imbalances.
"For the June 2026 electric bill of end consumers, NGCP charges only 56 centavos per kWh for the delivery of its services," the company said.
NGCP added that its revenues are subject to a cap and regulated by the Energy Regulatory Commission, emphasizing that ancillary services costs are pass-through charges paid to reserve power providers.
The lower transmission rates offer consumers modest relief as households continue to manage monthly utility expenses.
