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

The overall residential rate of Cotabato Light went up by P0.4320 per kilowatt hour (kWh) this August, increasing the rate to Php 8.33/kWh from P7.90/kWh last month. This rate applies to bills received from August 16, 2025 to September 15, 2025.

The increase in electricity rates is mainly because of higher power supply prices from the Wholesale Electricity Spot Market (WESM), where Cotabato Light gets part of its power needs. Added charges from the National Grid Corporation of the Philippines (NGCP) for reserve power services, along with an ERC regulation, also contributed to higher transmission costs. With this, Cotabato Light continues to encourage customers to manage their energy consumption and use electricity wisely to avoid high electricity bill.
