A house in Chile uses on average about 180 kWh of electricity a month. That is the consumption the National Energy Commission (CNE) uses as its typical customer to track bills, according to its Energy and Financial Report, and it matches regional data: in Arica y Parinacota, for example, average residential consumption is 181 kWh a month, according to the Ministry of Energy with Energía Abierta data.
At the kWh price in force since October 2026, those 180 kWh mean a bill of about CLP 47,000. Here is the calculation, how many watts a house uses and which appliances weigh the most.
How many kWh a house in Chile uses per month
| Reference consumption of a house in Chile | kWh per month | Source |
|---|---|---|
| Typical customer 1 (average household) | 180 kWh | CNE |
| Typical customer 2 (higher-consumption household) | 300 kWh | CNE |
| Average residential consumption in Arica y Parinacota | 181 kWh | Ministry of Energy (Energía Abierta) |
| Limit of the first charge bracket of the BT1 tariff | 350 kWh | Utilities' tariff schedules |
Consumption varies a lot depending on household size, location and, above all, heating. A house in the south heated with electricity can double or triple the average in winter, while a small apartment without electric heating can use less than 100 kWh.
The tariff also matters: about 90% of residential customers use less than 350 kWh a month, the limit of the first charge bracket, according to utility estimates cited by La Tercera. Going over that threshold makes each additional kWh more expensive.
How many watts a house uses: daily consumption
Watts measure power (how much energy is used at a given moment) and kWh measure energy (how much was used over a period). A house using 180 kWh a month consumes:
- Per month: 180 kWh.
- Per day: 6 kWh (180 ÷ 30), that is, 6,000 watt-hours.
- Average continuous power: 250 watts (6,000 Wh ÷ 24 hours).
- Per year: 2,160 kWh.
That 250 W average hides large variations: in the early morning the house may use less than 100 W (fridge and appliances on standby), and in the evening it can exceed 3,000 W if the kettle, microwave and washing machine run at the same time.
How much you pay for a house's electricity in Chile
In municipalities served by CGE, the residential kWh (BT1 tariff, first bracket) costs between CLP 240.83 and CLP 285.56 since October 1, 2026, plus a fixed charge of CLP 1,071.14 a month, according to CGE's tariff schedule. With the Rancagua or Concepción price (CLP 255.27 per kWh), the bill by consumption looks like this:
| Monthly consumption | Calculation | Approximate bill |
|---|---|---|
| 100 kWh | CLP 1,071 + 100 × CLP 255.27 | ~CLP 26,600 |
| 150 kWh | CLP 1,071 + 150 × CLP 255.27 | ~CLP 39,360 |
| 180 kWh (typical home) | CLP 1,071 + 180 × CLP 255.27 | ~CLP 47,020 |
| 250 kWh | CLP 1,071 + 250 × CLP 255.27 | ~CLP 64,890 |
| 300 kWh | CLP 1,071 + 300 × CLP 255.27 | ~CLP 77,650 |
| 350 kWh | CLP 1,071 + 350 × CLP 255.27 | ~CLP 90,420 |
These are reference amounts. If your average consumption last year exceeded 200 kWh a month, the distribution charge rises in brackets, and above 350 kWh a month the public service charge increases, so the real bill may be somewhat higher. The breakdown by municipality is in the price per kWh by city and utility.
An example from CGE's October schedule: in Rancagua, the distribution charge goes from CLP 33.652 to CLP 39.821 per kWh between households that averaged up to 200 kWh a month last year and those that averaged more than 240 kWh. For a 300 kWh house, that difference adds about CLP 1,850 a month.
Which appliances use the most
To understand where the 180 kWh come from, we built an example of the monthly consumption of a four-person household without electric heating. It is an estimate with typical power ratings and hours of use; your case may differ:
| Appliance | Usage assumption | kWh per month | Cost per month (at CLP 255.27) |
|---|---|---|---|
| 438-liter No Frost refrigerator | Label consumption: 36.2 kWh/month | 36 | ~CLP 9,240 |
| Kettle (2,000 W) | 20 minutes a day | 20 | ~CLP 5,110 |
| Washing machine with cold water | 12 loads a month, ~0.5 kWh each | 6 | ~CLP 1,530 |
| LED TV (100 W) | 5 hours a day | 15 | ~CLP 3,830 |
| LED lighting (10 bulbs of 9 W) | 5 hours a day | 13.5 | ~CLP 3,450 |
| Microwave (1,000 W) | 15 minutes a day | 7.5 | ~CLP 1,910 |
| Computer and router | Laptop 6 h and router 24 h | ~15 | ~CLP 3,830 |
| Iron, hair dryer and others | Occasional use | ~15 | ~CLP 3,830 |
| Standby devices | Chargers, set-top box, consoles | ~10 | ~CLP 2,550 |
| Example total | — | ~138 kWh | ~CLP 35,280 |
The example falls below the 180 kWh average because it does not include an electric shower, dryer, electric oven or heating. Any of them changes the bill: a 1,500 W electric heater used 4 hours a day adds 180 kWh a month on its own, as we calculated in how much low-consumption electric heaters cost to run.
The refrigerator is the appliance that weighs most in most homes because it runs 24 hours a day. We explain it in detail in how much electricity a refrigerator uses in watts and pesos.
Power of household appliances: a table of watts
These are typical nominal power ratings of household appliances. The exact figure for your appliance is on its rating plate or on the energy efficiency label:
| Appliance | Typical power | Consumption in 1 hour of use |
|---|---|---|
| Electric kettle | 1,800 to 2,200 W | ~2 kWh |
| Electric heater | 800 to 2,000 W | 0.8 to 2 kWh |
| Hair dryer | 1,200 to 2,000 W | 1.2 to 2 kWh |
| Microwave | 800 to 1,200 W | 0.8 to 1.2 kWh |
| Iron | 1,000 to 2,000 W | 1 to 2 kWh |
| 12,000 BTU air conditioner | ~1,100 W | ~1.1 kWh |
| LED TV | 50 to 150 W | 0.05 to 0.15 kWh |
| Laptop | 30 to 65 W | 0.03 to 0.07 kWh |
| LED bulb | 5 to 12 W | 0.005 to 0.012 kWh |
The rule for calculating any appliance is simple: watts × hours of use ÷ 1,000 = kWh. Then kWh × your municipality's kWh price = cost in pesos. For air conditioning, see how much electricity an air conditioner uses.

See advertising optionsHow to find out how much you use
- Look at your bill: it shows the month's consumption in kWh and a chart of the last 12 months.
- Read the meter: note the reading one day and at the same time the next day; the difference is your daily consumption in kWh.
- Use a plug-in meter: it costs little and shows how much each appliance uses.
- Check your utility's app: some show daily consumption if you have a smart meter.
How to lower electricity consumption
- Switch to LED any incandescent or halogen bulbs that remain.
- Heat with a heat pump (inverter air conditioner) instead of resistance heaters: it costs several times less per hour.
- Wash with cold water and with a full machine.
- Unplug what you don't use: standby consumption can add up to dozens of kWh a year.
- Check the refrigerator: if it is more than 10 years old, a new one with a good label can use considerably less.
- Boil only the water you need in the kettle.
How many solar panels a house in Chile needs
Knowing how much your house uses is the first step to sizing a solar system. To cover 180 kWh a month, the number of panels depends on the region and the season, because a panel generates considerably more in summer than in winter. With net billing, the energy you don't use is injected into the grid and discounted from the bill, although at a lower price than what you pay to buy it.
Frequently asked questions about household electricity use
How many kWh does an average house use in Chile?
About 180 kWh a month, the consumption the CNE uses as its typical household. In Arica y Parinacota, the residential average is 181 kWh.
How many watts does a house use per day?
About 6 kWh a day (6,000 Wh), equivalent to an average power of 250 watts over 24 hours.
How much does a house pay for 180 kWh?
About CLP 47,000 a month with CGE's kWh price in Rancagua or Concepción since October 2026 (CLP 255.27 per kWh plus a CLP 1,071 fixed charge).
How do I calculate how much an appliance uses?
Multiply its power in watts by the hours of use and divide by 1,000: the result is kWh. Then multiply by your municipality's kWh price.
Which appliance uses the most electricity in a house?
Without electric heating, it is usually the refrigerator, because it runs all day. With electric heating, the heater or the air conditioner becomes the largest expense in winter.
