How to Calculate Your Electrical Power

It is the first question that arises when subscribing to an electricity distributor.

In theory, the electrical power required is the sum of the forces of all the electrical devices available.

But in reality, it is much lower since not all devices work simultaneously. The type of accommodation and the nature of your electrical equipment will be the two main elements to consider to find the most suitable subscription.

### Electrical Power Calculation: Instructions for Use

Different electrical powers depend on the type of subscription, ranging from 3 to 36 kVA (kilovolt amperes).

Below is an idea of the electrical power that will be required for your lifestyle, your home, or your daily consumption:

– 3 kVA: this lowest electrical power is intended for people in a small house, with basic electrical appliances, without extra.

– 6 kVA: it is intended for an apartment or house with a surface area of around 100 m2 without a heating system. This power is sufficient for this type of residence if it is equipped with small electrical appliances, a tv set, or an electric oven.

– 9 kVA: always intended for homes of 100 m2, this higher power is justified by better electrical comfort with audiovisual equipment and a complete set of household appliances.

– 12 kVA: ideal power for a large heated home with comfortable electrical and electronic equipment.

– From 15 to 36 kVA: these high power ranges are more appropriate for people with large heated but poorly insulated living areas. They also have the particularity of having many electrical appliances and equipment.

### Electrical Power: What Happens If It Is Exceeded?

In the event of a specific overrun of the chosen electrical power, the general circuit-breaker is tripped, and the power supply is cut off throughout the entire housing. You must then restart it manually. The load shredder is a helpful device to avoid this type of inconvenience.

### Calculation of the Electrical Power

The electrical installation of your home is omnipresent in your daily life. Heating, lighting, household appliances: all your equipment is essential. But your facility has a cost and requires an appropriate subscription. To choose the right one for you, you must evaluate the needed electrical power. Here are some tips for calculating your electrical power.

### Electrical Power Calculation: How to Measure?

The electrical power calculation is based on the values specific to your electricity consumption, i.e., the voltage and intensity of your domestic installation. You can use several devices to calculate this data:

– Voltmeter: This device is used to measure the voltage of your electrical wiring measured in Volt (noted V). To evaluate the voltage delivered by your supplier, you must consider the voltage measurement specific to your home, i.e., the AC voltage.

– Ammeter: in analog or digital version, this device is used to evaluate the intensity of the electrical current flowing through them.

– Multi-meter: this measuring device makes it possible to calculate all the characteristic values of the current such as voltage, current, electrical power…

### Calculation of Electrical Power and Consumption Stations

The calculation of the electrical power will depend directly on the different consumption items of your home and the percentage of electrical consumption specific to each equipment:

– heating: nearly 50%;

– lighting: low energy consumption, about 3%;

– household appliances:

◦ dishwasher: on average, 14% of household appliance consumption;

◦ washing machine: 7%;

◦ tumble dryer: around 14%;

◦ refrigerator: on average, 32%;

◦ TV and audiovisual: 12%.

### Electrical Power Calculation: Which Subscription to Choose?

The subscription between the supplier and you runs for one year. You have 15 days to take out a new subscription or terminate a contract with your former supplier.

Multiply your requests for quotes or request simulations to choose the most advantageous offer.

You can also use your electrical power calculation to choose the right subscription to avoid overestimating your needs and paying more for nothing.

### Electricity Tariff and Calculation of Electrical Power

Suppliers offer à la carte subscriptions. You can choose fixed or variable rates depending on the time of year. Typically, more flexible subscriptions offer rates that adapt to peak and off-peak hours when the kilowatt-hour is the cheapest.
