How is Meralco Electricity Computed?
In the Philippines, electricity is billed based on Kilowatt-Hours (kWh). The basic formula is:
(Appliance Wattage ÷ 1000) × Hours Used × Days Used × Cost per kWh
Why does my Meralco bill fluctuate?
- Generation Charge: The cost of power purchased from suppliers changes monthly based on global fuel prices.
- System Loss Charge: Consumers pay for the power lost during transmission over the grid.
- Taxes and Subsidies: VAT, local franchise taxes, and lifeline subsidies are baked into the final per-kWh rate.
