National Grid Corporation of the Philippines on Wednesday said the overall transmission rate for May 2026 has been reduced and will be reflected in consumers’ electricity bills this month.

In an advisory, NGCP said the overall transmission charge for the April billing period, which will be billed by distribution utilities and electric cooperatives this month, dropped to P1.5983 per kilowatt-hour from P1.7526 per kWh in March, equivalent to an 8.8 percent decrease.

NGCP said the reduction was driven by lower transmission wheeling rates and ancillary services charges.

The fee for delivering electricity through the transmission grid declined by 14.16 percent, while ancillary services charges sourced from power generators decreased by 5.02 percent.

NGCP said only around 60 centavos of the total electricity bill charged to end consumers in May 2026 corresponds to transmission service delivery charges.

Meanwhile, ancillary services charges continue to be included in bulk transmission costs.

NGCP also clarified that it does not profit from ancillary services rates, saying the collections are directly remitted to generating companies.
