What Does “Per Kilowatt-Hour” Mean?

A kilowatt-hour (kWh) is the standard unit used to measure electricity consumption. Meralco charges customers based on how many kilowatt-hours they consume during the billing period. One kilowatt-hour means using 1,000 watts of electricity for one hour. For example:
  • A 100-watt electric fan running for 10 hours uses 1 kWh.
  • A 1,000-watt microwave running for 1 hour also uses 1 kWh.
  • An inverter air conditioner running for several hours daily can consume multiple kWh each day.
Your monthly Meralco bill is computed by multiplying your total kWh consumption by the applicable electricity rate, including all charges and adjustments.
The higher your kWh usage, the higher your electricity bill becomes. Large appliances like air conditioners, refrigerators, heaters, and dryers usually consume the most electricity.

Current Meralco Rate per kWh

As of April 2026, the residential electricity rate increased to approximately ₱14.3496 per kWh from ₱13.8161 per kWh in March 2026. This means:
  • 100 kWh consumption = approximately ₱1,434.96
  • 200 kWh consumption = approximately ₱2,869.92
  • 500 kWh consumption = approximately ₱7,174.80
Actual bills may vary depending on taxes, subsidies, lifeline discounts, adjustments, and billing cycles.

Complete Meralco Bill Breakdown

Generation Charge

The generation charge pays power suppliers and generation companies that produce electricity.

This is usually the largest component of the Meralco bill and is heavily affected by fuel prices, supply conditions, and electricity demand.

Approximately 55%

Transmission Charge

Transmission charges cover the cost of delivering electricity through the national grid operated by the National Grid Corporation of the Philippines (NGCP).

These charges include ancillary services and reserve market costs.

Approximately 10.1%

Distribution Charge

Distribution charges pay for Meralco’s distribution network operations, maintenance, transformers, substations, and customer services.

This portion supports electricity delivery from transmission lines to homes and businesses.

Approximately 17.5%

Taxes and Government Charges

Taxes include VAT, franchise taxes, universal charges, missionary electrification charges, and renewable energy subsidies.

These are government-mandated charges added to electricity bills.

Approximately 11.7%

System Loss Charge

System loss charges account for electricity lost during transmission and distribution due to technical and non-technical losses.

These losses occur before electricity reaches consumers.

Part of Other Charges

Feed-in Tariff Allowance (FIT-All)

FIT-All charges help fund renewable energy projects including solar, wind, hydro, and biomass energy developments.

This supports cleaner energy production in the Philippines.

Sample Meralco Bill Computation

Here is a simplified example of how electricity charges are computed for a household consuming 200 kWh in one month.
Charge Component Estimated Amount
Generation Charge ₱1,578.00
Transmission Charge ₱290.00
Distribution Charge ₱500.00
Taxes and Other Charges ₱501.92
Total Estimated Bill ₱2,869.92
This sample computation is only an estimate. Actual charges vary monthly depending on electricity rates, fuel costs, taxes, and adjustments.

Why Your Meralco Bill Changes Every Month

1

Seasonal Usage

Electricity usage increases during summer because of longer air conditioner and fan usage.

2

Fuel Price Changes

Coal, oil, and natural gas price increases directly affect electricity generation costs.

3

Peso Exchange Rate

A weaker peso increases costs for dollar-denominated power supply agreements.

4

Power Supply Conditions

Low power supply and high electricity demand increase WESM prices.

5

Appliance Usage

Adding appliances or increasing usage hours raises total kWh consumption.

6

Billing Adjustments

Refunds, subsidies, taxes, and government charges may change monthly.

How to Lower Your Electricity Consumption

Reducing your electricity consumption can help minimize the impact of higher Meralco rates.
1

Use Appliances Efficiently

Turn off appliances when not in use and avoid unnecessary standby power consumption.

2

Optimize Air Conditioner Settings

Set air conditioners around 25°C and clean filters regularly.

3

Switch to LED Lighting

LED bulbs consume significantly less electricity compared to traditional bulbs.

4

Monitor High-Consumption Appliances

Track usage of refrigerators, water heaters, air conditioners, and washing machines.

Use an Appliance Calculator

One of the best ways to understand your Meralco bill is by estimating the electricity consumption of each appliance individually. An appliance calculator can help you:
  • Estimate monthly appliance costs
  • Identify high-energy appliances
  • Reduce unnecessary usage
  • Manage electricity budgets more effectively
  • Estimate possible bill increases during high-rate months
