DAVAO Light’s overall residential electricity rate increased by P0.33 per kilowatt-hour (kWh), the power distribution utility announced on Wednesday.
This brings the new rate for March to P10.63 per kilowatt-hour (kWh), compared to last month’s rate of P10.30/kWh.
Davao Light said the increased rate applies to electricity bills received from March 12 to April 11, 2026.
“The rate adjustment is attributed to the higher prices from the Wholesale Electricity Spot Market (WESM),” it said in a press statement.
WESM is one of Davao Light’s supply sources, while 50% is hydropower from NPC Power Sector Assets and Liabilities Management, and around 20-30% is coal, which is from Therma South.
While the March-April rate increased to P10.63 per kWh, this is lower compared to the January to February rate of P11.7187/kWh.
The power distribution utility encourages customers to continue practicing efficient use of energy to avoid a high electricity bill shock.
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.
