Davao Light Announces Residential Electricity Rate Decrease for April 2026
Residential customers of Davao Light and Power Company (Davao Light) will experience a modest reduction in their electricity bills this April, even as the National Grid Corporation of the Philippines (NGCP) reports an increase in transmission charges across the country. This development offers some financial relief to consumers amid broader energy market fluctuations.
Rate Reduction Details and Billing Period
In a recent advisory, Davao Light revealed that the overall residential electricity rate has declined by ₱0.10 per kilowatt-hour (kWh). The new rate is now ₱10.53 per kWh, down from ₱10.63 per kWh in March 2026. This adjusted rate will apply to billing statements issued from April 12 to May 11, 2026, covering a full month of consumption for residential users.
Causes Behind the Decrease and Market Volatility
The distribution utility attributed this decrease primarily to lower power supply costs from the Wholesale Electricity Spot Market (WESM), which serves as one of its key energy sources. However, Davao Light cautioned that market prices remain highly volatile and may continue to fluctuate based on supply and demand conditions. Consumers were strongly urged to practice energy efficiency measures, as electricity rates are subject to monthly adjustments that can vary significantly.
National Transmission Charges Increase Despite Local Rate Cut
While Davao Light customers enjoy slight relief, NGCP reported that transmission charges reflected in April 2026 bills have increased nationwide. The overall equivalent average transmission rate for the March 2026 billing period rose by 4.26 percent to ₱1.7526 per kWh, up from ₱1.6810 per kWh in February.
Breakdown of Transmission Charge Components
A significant portion of this increase came from higher ancillary service (AS) rates, which escalated from ₱0.8275 per kWh to ₱0.8516 per kWh. These charges cover standby power supplied by generators during supply-demand imbalances, ensuring grid stability. NGCP clarified that these are pass-through costs and do not contribute to its revenue, as payments are directly remitted to power generators and to the Independent Electricity Market Operator of the Philippines for reserves sourced from the market.
NGCP emphasized its operational priorities: "As the system operator, NGCP’s priority is to ensure the grid remains resilient during supply-demand imbalances. NGCP does not profit from AS charges, as these are remitted directly to the providers who help us maintain the continuous flow of electricity across the country."
Transmission Wheeling Rate Adjustment
The transmission wheeling rate, which represents the cost of delivering electricity through the national grid, also increased slightly to ₱0.7022 per kWh in March from ₱0.6677 per kWh in February. Despite this adjustment, NGCP stressed that its allowable revenue remains strictly capped by the Energy Regulatory Commission (ERC), ensuring that such increases do not translate to additional profits for the corporation.
Assurance of Stable Power Supply Amid Global Uncertainties
Despite rising transmission charges and ongoing geopolitical tensions in the Middle East, Davao Light has assured consumers that electricity supply in its franchise area remains stable and reliable. The company stated that global developments are not expected to directly affect local power availability, thanks to its diversified supply sources and strategic procurement approaches designed to cushion against external disruptions.
This combination of local rate reductions and national transmission increases highlights the complex dynamics of the Philippine energy sector, where regional benefits can coexist with broader cost pressures.
