Cotabato Light Announces an increase in electricity rates for the billing month of September 2025

The overall residential rate of Cotabato Light went up by P1.7637 per kilowatt hour (kWh) this September, increasing the rate to Php 10.0952/kWh from P8.3315/kWh last month. This rate applies to bills received from September 16, 2025 to October 15, 2025.

The increase in electricity rates is mainly because of higher power supply prices from the Wholesale Electricity Spot Market (WESM), following power plant outages, which is among the factors that led to the yellow alerts issued by the National Grid Corporation of the Philippines (NGCP) last month. Increases in generation costs, particularly from the spot market, where Cotabato Light sources part of its power requirement, directly affect the overall rate charged to consumers. With this, Cotabato Light continues to encourage customers to manage their energy consumption and use electricity wisely to avoid high electricity bill.
