POWER RATES FOR OCTOBER 2026
Residential: ₱12.4840 → ₱12.4422/kWh (−₱0.0418)
Low Voltage: ₱11.6299 → ₱11.5807/kWh (−₱0.0492)
High Voltage: ₱9.6851 → ₱9.7579/kWh (+₱0.0728)
ZAMECO I would like to inform all Member-Consumer-Owners (MCOs) that the residential electricity rate for October 2026 is ₱12.4422 per kilowatt-hour (kWh). This is a decrease of ₱0.0418/kWh from the September 2026 rate of ₱12.4840/kWh.
The Low Voltage rate also decreased to ₱11.5807/kWh (a reduction of ₱0.0492/kWh), while the High Voltage rate increased to ₱9.7579/kWh (an increase of ₱0.0728/kWh), compared with September 2026.
THE MAIN REASON FOR THE DECREASE IN THE RESIDENTIAL RATE IS THE DROP IN TRANSMISSION AND SYSTEM LOSS CHARGES, DESPITE INCREASES IN GENERATION AND OTHER CHARGES.
For October 2026, the Generation Charge increased by ₱0.0364/kWh, from ₱7.2165/kWh in September to ₱7.2529/kWh. This charge reflects the cost of electricity purchased from power suppliers and the electricity market.
Meanwhile, the Transmission Charge decreased by ₱0.1146/kWh, System Loss by ₱0.0256/kWh, and Taxes/VAT by ₱0.0014/kWh. Other Charges increased by ₱0.0634/kWh, corresponding to the UC-ME increase from ₱0.2763 to ₱0.3397/kWh. The additional ₱0.0634/kWh is collectible for 36 months or until fully recovered, as directed by the ERC.
VAT ON SYSTEM LOSS: Under ERC Resolution Nos. 26 and 28, Series of 2026, and BIR RMC No. 97-2026, the allowable System Loss Charge is excluded from the VAT computation, subject to the ERC-prescribed system loss cap and billing requirements.
The collection of the Green Energy Auction Allowance (GEA-All) of ₱0.0371/kWh remains suspended for October 2026. Under the ERC Advisory dated August 19, 2026, the suspension covers September to December 2026 billing months.
Pursuant to the ERC Advisory dated May 5, 2026 under Executive Order No. 110, ZAMECO I implemented the Staggered Payment Scheme for applicable power costs to lessen the immediate impact on MCOs’ electricity bills.
ZAMECO I’s residential Distribution, Supply and Metering (DSM) Charge remains at ₱1.4640/kWh, unchanged since 2011. The Renewable Energy Certificate (REC) Rate is no longer collected, effective September 2026.
Electricity rates may change monthly due to market conditions and changes in the cost of power supply.
ZAMECO I encourages all MCOs to practice responsible electricity use and choose energy-efficient appliances to help manage their monthly consumption and bills.
MCOs are reminded to pay their monthly electricity bills on time to avoid accumulating balances. Thank you for your cooperation!
