The meter reading was similar to last month's. The kilowatt-hour consumption hardly changed. Even so, the amount to pay went up. The explanation is usually found in a small line on the bill, labeled with a color.
What the flag actually charges
The flag system exists to pass on to the consumer, month by month, how much it is costing. to generate The country's energy consumption—not how much you used.
Here's the situation: most of Brazil's electricity comes from hydroelectric power, which is cheap. When there's little rain and the reservoirs are low, thermal power plants, which are much more expensive, come into play. Someone has to pay for this difference, and the mechanism chosen was an additional charge on everyone's bill.
Hence the confusing effect: The flag goes up because of the reservoir levels, not your consumption.. You can spend exactly the same amount and pay more.
The colors and what each one means.
- Green: Favorable generation conditions. No additional charges.
- Yellow: Less comfortable condition. Small additional cost.
- Red level 1: Most expensive generation. Larger additional cost.
- Red level 2: The tightest situation in the system. It's the highest additional charge.
The color is announced monthly by the regulatory agency for the electricity sector and applies to practically the entire country. The additional charge is applied. for every 100 kilowatt-hours consumed In other words, those who spend more pay more extra, but the color itself is not a choice made by your distributor or your home.
Why your bill might increase more than your neighbor's.
Two houses on the same street, with the same tariff flag, experience the price increase differently. The tariff flag multiplies consumption—so those who already spend a lot feel it more in monetary terms.
Furthermore, the flag rate isn't the only item on the bill. Distribution fees, taxes, and public lighting fees are all included on the same bill. It's common for people to attribute an increase that came from elsewhere to the flag rate.
The consumption that exists even when everything is "switched off"“
Here's the most surprising part. Several devices continue to draw power even when switched off, because they are actually in standby mode — ready to respond to the remote control, update the clock, maintain the network.
The ones that appear most frequently on this list:
- Television, which is waiting for the remote control all the time.
- An internet router, which is normally never turned off.
- Microwave and electric oven with clock on the control panel.
- Chargers left plugged in with nothing connected.
- Video game and set-top box in fast standby mode.
Each one of these consumes very little energy. The problem is that there are many of them, and they're left on all the time—twenty-four hours a day, all month long. It's a small, constant leak, and that's why it shows up on your bill without showing up in your conscious usage.
What truly matters
Before hunting for an outlet, it's worth calibrating it. In a typical Brazilian home, the undisputed champion of energy consumption is the... electric shower. It uses a lot of power, and even when only on for a few minutes a day, it significantly increases the bill.
Next come appliances that combine high power with prolonged use: air conditioners, refrigerators—which never really turn off—and irons.
Having a backup device matters, but on a different scale. One minute less in the shower each day is usually worth more than unplugging the TV for the entire week.
How to discover the villain in your house.
You can do it without buying anything. Choose a day when the house is empty for an hour. Write down the electricity meter reading, leave only the essential appliances running, and write it down again after an hour. The difference is your baseline consumption—what the house uses without anyone doing anything.
Repeat the process, turning off one group of appliances at a time. In two or three measurements, you'll discover the leak's location with much greater accuracy than any generic estimate.
For those who prefer to estimate on paper, the calculation is straightforward: the appliance's power in watts, multiplied by the hours of use per month, divided by one thousand, gives the consumption in kilowatt-hours. Multiplied by your utility company's rate, that gives the total cost. The power rating is usually found on the appliance's label.
What can be done with the flag raised?
You don't control the color itself. What multiplies it, you can.
- Reducing shower time is the most effective measure per minute invested.
- Adjusting the air conditioner temperature by a few degrees noticeably changes energy consumption.
- Concentrating ironing in one session avoids having to reheat the iron multiple times.
- A power strip with a switch solves the standby power consumption problem for multiple appliances at once, without needing to unplug them.
Summary
The flag system represents the cost of generating energy in the country, set monthly and charged proportionally to your consumption. It explains why your bill goes up without any change in habits. And since you can't change the color of the flag, the solution is to attack what it multiplies—starting with the shower, not the TV outlet.
