TRANSMISSION charges for May, which will appear in June electricity bills, increased due to higher ancillary service (AS) charges, the National Grid Corp. of the Philippines (NGCP) said.
In a statement on Wednesday, NGCP said overall transmission rates increased by 4.6% month on month to P1.1482 per kilowatt-hour (kWh).
AS charges rose by 9.29% to P0.5655 per kWh.
Ancillary services are deployed by grid operators to support the transmission of power from generators to consumers and to maintain reliable operations.
These are pass-through charges billed by the grid operator and remitted directly to generation companies.
“As a pass-through cost, AS rates are only collected by NGCP and remitted directly to generation companies,” the grid operator said.
Transmission wheeling rates — or what NGCP charges for its primary service of delivering electricity — declined by 0.27% to P0.4593 per kWh.
Transmission charges reflect the cost of delivering electricity from power generators to the distribution system. — Sheldeen Joy Talavera
