PELCO I (Pampanga I Electric Cooperative) Bill Calculator

What is a kWh?

A kilowatt-hour (kWh) is the unit your electricity is sold in. One kWh is the amount of energy used by a 1,000-watt appliance running for one hour — for example, a 1,000-watt aircon running for one hour, or a 100-watt fan running for ten hours.

Your meter counts the total kWh your home has ever used. Your monthly bill charges you for the difference between this month's reading and last month's — that difference is your Actual Consumption for the month.

To see how much any specific appliance adds to that number, use the appliance calculator.

How is my electric bill computed?

Bakit ang mahal ng kuryente? Your electric bill is not a single charge — it is the sum of several separate charges stacked together, and only one of them is the electricity itself.

Every residential bill in the Philippines is built from the same set of components, set under the ERC's unbundled-rate structure:

1. Generation charge — the cost of producing the electricity. This is usually the largest single part of your bill, and it changes month to month.
2. Transmission charge — the cost of moving electricity across the national grid.
3. System loss charge — recovers electricity lost in transmission and distribution before it reaches you.
4. Distribution charge — PELCO I's share, for delivering power through local lines to your meter.
5. Subsidies and government charges — including the lifeline rate subsidy and universal charges set by national policy.
6. Taxes — including VAT and local franchise tax.
7. Universal charges and other pass-through items — nationally mandated recoveries such as FIT-All.

The important part most calculators get wrong: VAT is not a flat 12% on the whole bill. It is applied per component, at rates that vary by charge and by month. Your bill's total reflects each charge's own VAT treatment, not one blanket percentage.

What do the charges on my bill mean?

Each line on your bill recovers a different real cost. Here is what each one actually pays for:

• Generation — the electricity itself, bought from power producers. Not kept by your distribution utility; passed through at cost.
• Transmission — paid to the operator of the national grid for carrying power long distances.
• System loss — a small share of electricity is always lost as it travels. This charge recovers that loss, within a cap set by the ERC so utilities cannot pass on unlimited losses.
• Distribution — this is the part that actually goes to PELCO I, for maintaining the local poles, wires, and meters that bring power to your home.
• Taxes — VAT (applied per component, not as a flat rate) and local franchise tax, which varies by city.
• Subsidies and universal charges — nationally set items such as the lifeline rate subsidy and FIT-All, the same for every utility.

Because generation, transmission, and system loss are passed through at cost, most of your bill is not money your utility keeps — it is cost recovered on behalf of power producers, the grid, and the government.

Why is there VAT on my electricity, and what is it charged on?

Electricity is subject to value-added tax (VAT) like most goods and services in the Philippines. The part that confuses most people is not whether VAT applies, but what it is charged on.

VAT is not a flat 12% added to your bill total. It is applied separately to individual components, and the rate is not the same for every component. Some charges carry VAT; the exact VAT amount is calculated per component and can vary month to month. This is why two bills with the same total kWh can carry slightly different total VAT.

This matters because many bill calculators simply multiply the whole bill by 12%, which produces a wrong figure. A correct calculation applies VAT the way your actual bill does — component by component.

There is currently active national discussion about removing or reducing VAT on certain electricity charges, including VAT on system loss. Any change there would affect the per-component VAT, not a single blanket rate.

What is system loss?

System loss is the electricity that is produced but never reaches a customer's meter — lost as heat in wires, in transformers, and to a smaller degree through pilferage, as power travels from the plant to your home.

Because someone has to pay for the electricity that was generated but lost, this cost appears on your bill as the system loss charge. To protect customers, the ERC caps how much system loss a utility is allowed to pass on — a utility cannot bill you for unlimited losses, only up to the regulated cap.

How does the lifeline discount work?

There are two different things on your bill with "lifeline" in the name, and they are easy to confuse.

1. The Lifeline Rate Subsidy — a charge everyone pays. This appears on nearly every residential bill as a small per-kWh amount. It is not a discount to you; it is a universal charge that funds the discount for those who qualify. Every customer contributes to it.

2. The Lifeline Discount — a benefit only registered low-income customers receive. This is a genuine discount, but it is not applied automatically just because your usage is low. Under Republic Act 11552, a customer must be registered as a qualified lifeline beneficiary to receive it. Low consumption alone does not trigger it.

This is why a bill can show low usage and still pay full rates: the household simply is not registered under the lifeline program. The discount is tied to registration, not to a kWh threshold.

Most calculators get this wrong by auto-applying a lifeline discount whenever usage falls below a certain level. That produces a total lower than the real bill for any unregistered household — which is the majority.

Why did my bill go up this month?

A higher bill usually comes down to one of four things:

1. You used more electricity. The most common reason — a hotter month means more aircon hours. Check your Actual Consumption (this month's kWh) against the same month last year, not last month, since usage is seasonal.
2. The rate went up. Generation, transmission, and system loss are pass-through charges — your utility does not set them. They move with global fuel prices and the peso-to-dollar exchange rate, so your per-kWh rate changes every month even if your usage does not.
3. The billing period was longer. A bill covering 33 days will be higher than one covering 28, for the same daily usage. Check the number of billing days printed on the bill.
4. You lost a discount or crossed a tax threshold. Some charges and taxes change as consumption rises past certain levels.

Where to look first: read your own meter mid-month to see your usage pace before the bill arrives, compare against the same month a year ago, and check the billing-day count. To find which appliances are driving the number, use the appliance calculator.

About these estimates

This calculator estimates your bill from the official PELCO I residential rates for the current billing month. It cannot see everything on a real bill — security deposits, credits, previous-balance adjustments, or arrears are not included, because those are specific to your account and not to the rate schedule.

In bill-entry mode, the estimated kWh is rounded, because a bill total can map to a small range of possible consumption. The result is an accurate estimate of the rate-driven portion of your bill, not a reproduction of every account-specific line.

PELCO I is a cooperative, so there's no Local Franchise Tax line

Unlike Meralco and the site's other private utilities, Pampanga I Electric Cooperative (PELCO I) isn't a company operating under a city or municipal franchise — it's a member-owned electric cooperative regulated by the National Electrification Administration. That's why you won't find a "Local Franchise Tax" line on a PELCO I bill, and this calculator doesn't add one.

The REC Rate is currently zero

PELCO I bills carry a line called "REC Rate," for Renewable Energy Certificates. On every real bill checked so far it shows ₱0.00 — it's a defined charge on the official rate schedule that simply isn't active right now, and the calculator reflects that rather than guessing at a rate.

PELCO I and PELCO II are separate cooperatives

Despite the near-identical name and bill layout, PELCO I and PELCO II are two distinct electric cooperatives with separate rates, separate power supply contracts, and separate franchise areas. PELCO I serves Arayat, Candaba, Magalang, Mexico, San Luis, and Sta. Ana; PELCO II serves a different set of Pampanga municipalities entirely. If you're not sure which one applies to you, check the utility name printed on your own bill.

Who PELCO I serves

Pampanga I Electric Cooperative (PELCO I) is the distribution utility for Arayat, Candaba, Magalang, Mexico, San Luis, and Sta. Ana, all in Pampanga. Its head office is in Sto. Domingo, Mexico. If you live outside this franchise area, your electricity is likely provided by a different utility — including PELCO II, a separate cooperative — and this calculator's rates will not match your bill.
