DAVAO Light’s overall residential electricity rate dropped by ₱0.3477 per kilowatt-hour (kWh) this December, the power distribution utility announced on Tuesday.
This brings the new rate down to ₱9.7135/kWh, lower than ₱10.0612/kWh in November.
Davao Light said the reduced rate applies to electricity bills received from Dec. 11, 2025, to January 10, 2026.
“This adjustment is largely driven by lower power prices at the Wholesale Electricity Spot Market (WESM), one of the sources of Davao Light’s power supply,” it said in a press statement.
“Market prices are volatile, resulting in regular monthly changes in power rates,” it added.
Davao Light urged customers to manage consumption, especially as the holiday season approaches.
Davao Light recommended checking the estimated daily or monthly energy usage for each appliance by determining the appliance wattage, the average number of hours the household uses, the number of days the household uses the appliance in a month, and checking the rates.
To calculate the Kilowatt-Hours (kWh), the formula is Wattage / 1000 x Hours Used x Days = Total kWh. To estimate the cost, the total kWh should be multiplied by the rate
