The overall residential rate of Davao Light for the billing period of September 11 to October 10, 2026 is Php13.24 per kilowatt-hour (kWh), up by Php0.34/kWh from last month’s Php12.90/kWh.
The increase is mainly due to higher Wholesale Electricity Spot Market (WESM) prices, driven by tight power supply conditions in Mindanao, particularly during periods of high demand, raising the cost of electricity supplied to customers.
To help cushion customers from high WESM prices, the Energy Regulatory Commission (ERC) directed the regional implementation of the Secondary Price Cap (SPC) in the Visayas and Mindanao grids, retroactive to August 2026. The ERC also ordered the recalculation of market settlements to reflect the Price Cap-adjusted charges in customer bills.
Separately, Davao Light secured ERC approval to defer part of the generation charges, allowing the amount to be collected in installments instead of all at once, helping ease the impact of higher electricity costs.
Electricity rates may change from one billing period to another as generation costs and market conditions change. Customers are encouraged to continue practicing energy efficiency to help manage their electricity consumption and monthly bills.
