Manila: Lower transmission wheeling and ancillary services (AS) rates pushed overall transmission charges down for the June 2026 billing period, according to the National Grid Corporation of the Philippines (NGCP).
According to Philippines News Agency, NGCP Revenue Management head Julius Ryan Datingaling stated in a briefing on Monday that the overall transmission rate for power consumers fell by 9.33 percent to PHP1.4492 per kilowatt-hour (kWh) in the May 2026 billing period. This reduction will be reflected in this month's electricity bills, decreasing from PHP1.5983/kWh in April.
He attributed the decline to lower wheeling rates, or the cost of delivering electricity through the grid, which decreased from PHP0.6028/kWh in April to PHP0.5607/kWh in May.
The AS rate, or the pass-through cost of services from the reserve market and bilateral contract providers to NGCP to stabilize the grid during supply and demand imbalances, also declined to PHP0.7220/kWh in May from PHP0.8088/kWh in the previous month.
"For the June 2026 electric bill of end consumers, NGCP charges only 56 centavos per kWh for the delivery of its services," NGCP said in a statement.
NGCP officials emphasized that the transmission service provider does not earn more than what the Energy Regulatory Commission has authorized because its revenues are capped and regulated.
