How is the electricity consumption of a house calculated?

calculated electricity consumption of a house It is a fundamental aspect that you need to take into account before thinking about how to save on the bill. He power supply is basic needs the cost of which is paid through the electricity bill and its price will vary depending on the actual consumption.

We can define electricity consumption as the amount of energy used at a given feed point in a given period of time (invoicing period). Consumption is billed by marketers, who have set a price in kilowatt-hours (kWh), which will determine the total amount to be paid for the period\’s electricity consumption.

But most users don\’t know exactly what they\’re paying for, what concept they\’re paying for, and which devices consume the most in their home. For this reason it is very important to know as Calculate the electricity consumption of our house. In this way we can reduce the amount of the electricity bill while changing our energy consumption habits.

at the time of contract with a specific marketing agentit is essential to know forecast what our electricity consumption will beso that we can choose the rate that best suits our needs and habits Indoors.

Various formulas for performing the calculation

For Calculate our electricity consumption and what amount we have to pay on the electricity bill for the electricity consumption achieved in a certain period, we have to multiply these two concepts: the number of kWh consumed or the kWh price set by the contracted company. This price is set through an auction where traders buy power from electricity generators to later sell to their customers.

Others Important concepts to keep in mind to calculate electricity consumption by one place to live son:

  • Contracted power. It is the amount of energy used to connect different electrical appliances, so it will vary from one house to another according to the needs of each of them and their inhabitants. The most normal is that the more people live in a house, the more contracted power you have.
  • Electricity taxwhich represents 5% of the sum of power and consumption.
  • Rental of the electric consumption meterwhich has a daily cost that we need to multiply by the number of billing days.
  • VAT, which represents 21% of the total previous mandates.

let\’s see next some formulas for calculating electricity consumption in a home:

  • Measure the power of each electrical appliance and its operating time. To do this we must apply the following formula: Electrical power x Time of use = Energy consumed. That amount of kWh consumed will have to be multiplied by the price at which they are contracted.
  • Use an electricity consumption calculator. A useful tool that allows you to calculate the electricity consumption of a house taking into account the devices used and the number of its inhabitants. To calculate the electricity consumption of a certain device in euros, we can use various simulators that obtain these results.
  • Through an electricity consumption meter. This device allows us to know the use of electricity we make throughout the day. It can be rented from the contracted distributor for a variable cost. Thanks to its use, we can reduce the electricity bill by up to 15%.
  • Applications for estimating electricity consumption. A simple and fast method that only requires knowing the square meters of the property, the people who live in it, the connected devices and the spending habits.

What is the average consumption of a home?

As I mentioned before, not all homes use the same amount of energy electric. According to Red Eléctrica de España (REE), the the monthly kWh consumption of a Spanish household it is about 270 kWhwhich is equivalent to a total of 3,272 kWh/year approximate. However, the amount of energy consumed in every house varies according to the following parameters:

  • Features and dimensions of the house.
  • The electrical devices that are in the property.
  • Supply location.
  • The number of inhabitants of the household.
  • Consumption habits of the inhabitants.

It is also important to note that the consumption of each electrical device varies depending on its efficiency and its good or bad use.

What is an electricity consumption meter?

And electric meter provides the ability to measures the electricity consumption made by one or more electrical appliances in a home, making it possible to analyze the global consumption of the entire home. Its calculation capacity depends on the type of electricity consumption meter we install:

  • Individual consumption meter. It is able to calculate the kWh used by one or more electrical devices connected to the same outlet. Depending on the model we use, its historical storage capacity will vary. Some offer the possibility to calculate the electricity consumption of an appliance in euros by entering the price of the tariff that we have contracted.
  • Global consumption meter. It is connected to the electrical panel of the house to measure the total electrical consumption of the house. This type of meter can be accompanied by a desktop monitor that provides the information obtained or shares this information with a computer, phone or tablet.
