Electrical power is a fundamental aspect to consider when contracting the energy supply for an electrical project or installation. Calculating adequate electrical power is essential to ensure efficient and safe operation of electrical equipment and systems. In this article, we will explore in detail how to calculate the electrical power to be contracted, providing a technical and neutral approach to understand the key concepts and perform the necessary calculations.

1. What is contracted electrical power?

The contracted electrical power is the maximum amount of electrical energy that a consumer can use simultaneously in their home or commercial premises. It is measured in kilowatts (kW) and is determined by the maximum power that the elements of the property's electrical installation can withstand.

To determine the appropriate contracted electrical power, it is necessary to take into account the type of supply (single-phase or three-phase), the usual electrical consumption and the power necessary for the different appliances and devices used in the property.

It is important to correctly adjust the contracted electrical power, since a value that is too low could cause the electrical devices to not work properly, while an excessively high value can cause an extra cost on the electricity bill. Before making any modification to the contracted power, it is advisable to consult an electrician or specialized technician to determine the optimal power according to the needs of the home or business.

2. Components that influence the calculation of the electrical power to be contracted

To calculate the electrical power that must be contracted, it is necessary to take into account several components that directly affect this calculation. One of the most important factors is the type of electrical supply required. Depending on whether it is a single-phase or three-phase supply, the power required can vary considerably. It is essential to know this information to make an accurate calculation.

Another component to consider is the power demanded by the electrical appliances that will be used in the installation. It is important to identify and add the rated power of each piece of equipment, making sure to take into account both those already in use and those that are planned to be added in the future. Furthermore, it is essential to take into account the simultaneity factor, since not all equipment works at the same time at the maximum of its nominal power.

In addition to the components mentioned above, there are other factors that influence the calculation of the electrical power to be contracted. Among them are the length and section of the cables used in the installation, the energy efficiency of electrical appliances, the times of highest energy demand in the area, among others. Considering all these components in the power calculation will guarantee an adequate and efficient electricity supply.

3. Calculation of the electrical power necessary for a home

It is essential to correctly size the electrical installation and avoid overloads or supply failures. To carry out this calculation, it is necessary to take into account various factors that will determine the amount of electrical power required.

One of the key elements to take into account is the number of appliances and electrical devices used in the home. It is important to make an inventory of all the equipment and write down the power of each of them. This information can be found on the labels of the devices or consult the manufacturer's manual.

In addition, it is necessary to consider the simultaneous use of the equipment. For example, it is likely that several people in a household use different devices at the same time, such as the oven, the washing machine and the air conditioner. Therefore, it is essential to add the powers of the equipment that would be used simultaneously to achieve the electrical power necessary at that moment.

4. Factors to consider when determining the electrical power to contract for a business

When determining the electrical power to contract for a business, there are several factors to consider to ensure that energy needs are met. efficiently. These factors include:

• Trade size: The size of the establishment is a key factor in determining the electrical power required. It is important to calculate the total area and consider the different spaces, such as sales areas, warehouses and offices, to determine the necessary electrical load.
• Equipment and machinery: It is essential to identify and evaluate all electrical machines, equipment and instruments in business. Each appliance has a specific power demand, so it is important to review the manuals or consult with the supplier to obtain this data.
• Historical consumption: Analyzing the historical consumption of electrical energy of the business can provide an approximate idea of ​​the necessary power. Reviewing past bills and usage records can help determine average energy demand and make adjustments if an increase or decrease in demand is expected.

In addition to these key factors, it is important to consider the possibility of future expansions or changes in trade. If anticipated growth in the business is anticipated, it is advisable to contract for higher power to avoid interruptions in the electricity supply. The availability and capacity of the local electrical network to meet the required demand must also be taken into account.

Once all of these factors have been considered, it is advisable to consult with a professional or specialized electrician to determine the optimal electrical power for the business. These experts can perform accurate calculations and advise on specific requirements in accordance with local rules and regulations.

5. Tools and formulas to calculate the electrical power to be contracted
