The average residential electricity rate for June 2026 is ₱13.8417 per kilowatt-hour (kWh), an increase of ₱2.4609 per kWh
The average residential electricity rate for June 2026 is ₱13.8417 per kilowatt-hour (kWh), an increase of ₱2.4609 per kWh from May 2026.
In the interest of transparency, Negros Power has informed consumers of an increase in electricity rates for June 2026. Engr. Leomel Tambanillo, Assistant Vice President for Planning and Business Operations, emphasized that the adjustment is not unique to the company and is expected to be experienced by electric distribution utilities across the Visayas due to higher power generation costs.
June 2026 Power Rates Increase in the Visayas
The average residential electricity rate for June 2026 is ₱13.8417 per kilowatt-hour (kWh), an increase of ₱2.4609 per kWh from May 2026’s rate of ₱11.3808 per kWh.
According to Negros Power, the increase was primarily driven by higher costs of purchasing electricity from power suppliers.
WESM Price Increase
One of the major contributors was the significant increase in prices at the Wholesale Electricity Spot Market (WESM). Electricity prices in the spot market more than doubled during the month due to the limited available power supply.
Several power plants were unavailable while electricity demand remained high, prompting the National Grid Corporation of the Philippines (NGCP) to declare Yellow and Red Alerts in both the Luzon and Visayas grids.
In addition, power purchased from CENPRI became more expensive due to rising fuel prices in the global market, further increasing generation charges.
Engr. Christian John Villena, Energy Sourcing Manager of Negros Power, explained that the increase reflects prevailing market conditions affecting the entire Visayas grid and not just a single distribution utility.
“In the interest of transparency, we want our consumers to understand that this increase is primarily due to higher generation costs resulting from limited power supply and increased fuel prices. The significant rise in WESM prices, coupled with higher costs from our power suppliers, has affected electricity rates throughout the region. This is not a situation unique to Negros Power. Electric distribution utilities across the Visayas are likewise expected to register increases in their electricity rates because these generation costs are driven by conditions affecting the entire grid,” Villena said.
He added that generation charges are pass-through costs and do not form part of the distribution utility’s revenues.
While transmission charges posted a slight decrease during the month, the reduction was not enough to offset the increase in generation costs.
For June 2026, the average electricity rates are as follows:
- Residential (RES): ₱13.8417/kWh
- Low Voltage (LV): ₱13.7469/kWh
- High Voltage (HV): ₱12.8694/kWh
Negros Power reiterated its commitment to transparency by keeping consumers informed about the factors affecting their electricity bills. The company also continues to pursue the most competitive and reliable power supply sources available while encouraging consumers to adopt energy-efficient practices to help manage electricity consumption.
As power supply conditions and fuel prices continue to influence generation costs, Negros Power assures its consumers that it remains committed to delivering reliable service and providing timely information on developments affecting electricity rates.
