Your electricity bill is more readable than it looks. Once you know which sections to focus on, you can understand your charges in under 10 minutes — and identify where savings are actually possible.
The Three Major Cost Buckets
Every Philippine electricity bill, regardless of distributor, is divided into three regulated layers:
-
Generation Charge — what the power plants charge for producing electricity. This is the largest component and the one most affected by fuel prices and supply contracts. In 2025, this accounted for roughly 45–50% of the average Meralco bill.
-
Transmission Charge — what the National Grid Corporation of the Philippines (NGCP) charges for moving power from plants to substations. This is relatively stable and represents about 10–12% of your bill.
-
Distribution, Supply, and Metering Charges — what your local distributor charges for the last-mile infrastructure. This is fixed within rate reset cycles and makes up roughly 18–22%.
The Pass-Through Charges You Can’t Negotiate
Several line items are collected by your distributor but passed directly to government agencies:
- Universal Charge — funds missionary electrification, stranded debts, and renewable energy
- FIT-All — feed-in tariff collected to subsidize renewable energy developers
- Local Franchise Tax — a percentage of revenues remitted to the LGU
- Government taxes (VAT, national franchise tax) — applied to the total
These represent 15–20% of your bill and cannot be reduced at the household level.
What You Can Actually Influence
- Generation Charge — switching to a Retail Electricity Supplier (RES) under the RCOA allows contestable customers to shop for cheaper generation contracts. Community aggregation lets non-contestable customers access this market collectively.
- Consumption volume — efficiency measures, time-of-use shifting, and solar self-consumption reduce the kWh your bill is calculated on.
Reading the Summary Page
Look for three numbers: (1) your kWh consumed, (2) the effective all-in rate per kWh (total bill ÷ kWh), and (3) the generation component per kWh. If your effective rate is above ₱11/kWh, you’re in the typical Meralco range. Aggregation participants typically report effective rates 10–18% lower after their first full billing cycle.
