For April 2026, the average residential electricity rate increased to ₱12.2463 per kilowatt-hour (kWh), up by ₱0.8356/kWh from the March 2026 rate of ₱11.4107/kWh.
This increase is mainly due to higher power supply costs and increased transmission-related charges affecting consumers in the Visayas.
Why did the rate increase?
1. Higher cost of electricity supply (generation)
• Prices from the electricity market (WESM) increased.
• This was due to the unexpected shutdown of some power plants, resulting in reduced electricity supply.
• When supply is low—especially during peak hours—prices tend to rise.
• Additionally, supply from another power provider resumed, which, combined with higher market prices, contributed to the overall increase.
2. Increase in transmission charges
• Fees for maintaining and stabilizing the power grid (ancillary services) also increased.
• This resulted in a slight increase in the overall bill.
Summary of Rates (April 2026)
Residential: ₱12.2463/kWh
Low Voltage: ₱12.5389/kWh
High Voltage: ₱11.1646/kWh
These changes are driven by market conditions and industry-related charges that impact all electricity consumers.
Negros Power does not set these costs, as they are pass-through charges based on supply conditions and grid-related expenses. The company remains committed to keeping consumers informed about electricity rate movements.
