The allocated power of the electric power. Estimated power: how to handle electricity correctly

As mentioned above, 06/04/2012. new rules for retail electricity markets came into force. The main changes for consumers in the rules are described in the previous article. However, one point should be emphasized in particular.

So, this moment concerns consumers with a maximum power of over 670 kW. The maximum power is determined in the power supply contract with the guaranteeing supplier and should not exceed the permitted power in the documents issued by the grid organization to the consumer in the course of technological connection(it is specified in the act of technological connection). It should be noted that earlier consumers with a maximum power of more than 670 kW were referred to as consumers with a connected power of more than 750 kVA. And yet, what important changes have occurred for such consumers:

1. In accordance with paragraph 139 of the "Basic Provisions for the Functioning of Retail Electricity Markets", approved by Decree of the Government of the Russian Federation of 04.05.2012. No. 442 for accounting electrical energy for consumers with a maximum power of at least 670 kW, metering devices with an accuracy class of 0.5S and above are subject to use, as well as providing storage of data on hourly volumes of electrical energy consumption for the last 120 days or more. At the same time, in accordance with clause 143, if consumers have several points of supply, then all these points of supply must be equipped with metering devices that allow measuring hourly volumes of electricity consumption. In order to make it much easier to take hourly readings of metering devices, such consumers can install ASKUE at their facility.

2. In accordance with clause 97 of the "Basic Provisions", consumers with a maximum power exceeding 670 kW until July 1, 2013. can choose any price category (subject to the fulfillment of all necessary activities), and after July 1, 2013. can only choose between 3-6 price categories (Recall that these price categories require the presence of an hourly meter). If the consumer has not chosen a price category, then he automatically falls into the 3rd or 4th price category from July 1.

3. In the event that the specified consumer has not delivered before July 1, 2013. metering devices that allow you to determine consumption by hours of the day, then for calculating the cost of electricity for 3-6 price categories from July 1, 2013. will apply it maximum power at the highest prices. (Section 181 of the Basic Provisions). The cost of electricity in this case can increase for the consumer by 50%. Learn more about the calculation procedure for price categories see the relevant section.

4. Suppliers of last resort from July 1, 2012 must indicate the value of the reserved (maximum) power in invoices for payment to consumers with a maximum power of more than 670 kW. This value should be determined as the difference between the actual power of the consumer and its maximum power (the one that was obtained in the process of technological connection to the power grids). Moreover, this reserved capacity will be presented for payment to such a consumer in the near future. Those. if the actual capacity is less than the maximum for any reason (temporary decrease in production), then the consumer must pay for it! On the this moment the price has not yet been determined. If the cost of paying for the reserved capacity is too high for the consumer, then he can give up part of his maximum capacity (which was fully paid during the process of technical connection) in favor of the grid company.

This item is intended to ensure that the consumer understands how much in a year he will have to pay extra.

Important! At the moment, legislators are only discussing the possibility of a real introduction of the reserve payment since 07/01/2013, the reserve payment has not been introduced. But according to sources from the Ministry of Energy of the Russian Federation, the issue of paying for the reserve is being actively discussed, and after 2014 the payment for the reserve will be gradually introduced.

Thus, in connection with the entry into force of the new basic provisions, medium and large consumers are required to install new metering devices before July 1 (if the old ones do not meet the requirements specified in clause 1), as well as weigh all the pros and cons of failure part of its maximum power. If this condition is not met, then the cost of electricity for such consumers will increase significantly.

It should be noted that the cost of such an electricity meter is from 5,000 rubles without installation.

In the gallery we place some parts of the presentation on changes in the work in the retail electricity markets by Alexander Shkolnikov (OJSC Smolenskenergosbyt)

IN modern conditions there is a constant increase in electricity consumption. The data obtained show that the capacity of only kitchen equipment has doubled. In addition, there appeared a large number of air conditioners, computers and other equipment. Most electrical networks can no longer cope with increasing loads. Therefore, each owner of an apartment or a private house should have an idea of ​​​​what is the estimated and installed capacity. This problem fully applies to industrial enterprises with modern energy-intensive equipment.

What is rated power

Not only in new, but also in old houses, homeowners connect new types household appliances and equipment. Increasing the load can cause malfunctions electrical network, therefore, the question of the power of the supplied cable must be clarified in advance. This information can be found in the act of delimitation of balance responsibility or in the certificate of permitted capacities, which indicates the specific design and installed capacity.

The definition of rated power is also known as simultaneous switching power. This parameter indicates possible connection the established number of consumers available in the apartment. If unnecessary equipment is turned on, automatic protective devices will simply fail. The sum of the capacities of all devices will correspond to the installed capacity. However, in the case of simultaneous switching on, significant overloads will occur in the network, which will lead to the operation of protective devices. It is the means of protection that allow you to set a certain load limit allowed for a particular housing.

In many ways, the value of the calculated power depends on the input. Each landing is equipped through which a cable with the required cross section is entered into the apartment. After that, all other elements of the power supply system are placed inside the room, including a shield with load distribution devices along separate lines.

In most houses old building a single-phase power supply with a voltage of 220 V is connected. It is this connection that prevents excessive load on the line and makes it impossible to connect all modern appliances. This problem is solved using a three-phase 380 volt input. It consists of three lines that redistribute the total load. In the case of intensive energy consumption, there is an even distribution of the load on each phase.

Therefore, before planning the purchase of household appliances and equipment, it is necessary to find out in advance what current is supplied to the apartment. If three phases are connected, then there will be no problems, since one input accounts for from 14 to 20 kW, which allows you to freely connect all the necessary devices. However, in old buildings with single-phase input and aluminum cable, the maximum load power is only 4 kW. In this case, the use of any devices other than lighting is out of the question. Additional capacity will be required, and the relevant authorities should be contacted on this issue.

What is installed capacity

In order to plan in advance the installation of household appliances and equipment in a house or apartment, it is necessary to assess the maximum power that will be consumed from the electrical network. A simple arithmetic addition of the capacities of all available consumers does not give accurate results, due to its inefficiency and uneconomical.

As a rule, this assessment uses certain factors that take into account the utilization rate and the variance in the operation of connected devices. In addition, not only actual, but also expected loads are taken into account. The result is the installed power, measured in kW or kVA.

The value of the installed power will be equal to the sum of the rated powers of each device and device. However, this value will not be the actual power consumption, which is almost always higher than the nominal value. This parameter must be known in order to correctly select the rated power of a device.

IN industrial production there is the concept of total installed power. This indicator is the arithmetic sum of the total capacities of each individual consumer. It is not the same as the maximum rated apparent power because different factors and corrections are used in its calculations.

How to increase the calculated power

If the technical conditions make it possible to allocate additional power, in this case, an appropriate permission to perform electrical work. As a result, an additional cable of the required section, determined by specialists, will be introduced. This will allow you to withstand all the expected loads.

However, in practice, the solution of this problem is associated with great difficulties, primarily related to the coordination in various structures and instances. In addition, there are no additional capacities and there is simply nowhere to take them. Existing networks are already operating at full capacity. Sometimes additional capacities are located in another area, which will require laying a new one to the house. cable line. A new main power cable is also being laid inside the house. All changes are documented and recorded in the technical passport of the dwelling.

Particular difficulties arise in old houses with single-phase lines and no grounding. Replacement won't help here. old wiring to a newer throughput will still remain old and will not allow you to turn on additional devices. In this case, a complete replacement of the wiring with a three-phase line will be required with the installation of all necessary protective and switchgear devices.

Electricity consumption is constantly increasing. According to the latest data, only the kitchen in a standard apartment began to spend twice as much. But besides this, computers, air conditioners, microwaves… Power grids that have been operating for decades often cannot cope with today's demands. In this situation, it is important to have an idea of ​​​​what the calculated power is and what load the network in your apartment can withstand.

How much electricity does your apartment use?

Residents of new old houses today connect all necessary equipment: computer, oven, microwave, air conditioning, stove and extractor. To avoid a power outage, you need to find out in advance how powerful the cable is to the apartment. That is, to what extent it can be loaded.

These data are contained in two documents. First - « The act of delimitation of balance responsibility » . It indicates which trails the tenant owns and what the terms of that ownership are. You can get this paper in the HOA or in another service of operation. Second document - « Information about permitted capacities » . Here, specific figures for the estimated and installed capacity are already indicated.

Estimated power(or one-time switching power) is the power that makes it possible to connect a certain amount of technology in the apartment. If something else is connected in addition, the protective automation will fail. If you add together the power of all electrical equipment in the apartment, you get the installed power. But we cannot connect all at once, as the network will be overloaded, and protective automation will again work. It includes RCDs, differential automata. Thanks to protective automation, we ourselves determine how much we can load the network in the apartment. In older houses, these numbers, of course, will be less.

There is such a concept as input". Let's explain clearly. On the landing there is an electrical panel, an introductory machine, from which the cable goes to the apartment. If the whole system is located inside the apartment itself, then the cable starts desired section. After that, an automatic machine is installed that protects the wiring, then a meter, then an additional machine and a shield that distributes the load along the lines.

In most old houses, the power supply single-phase- classic 220 volt. Just it does not allow to load the line too much and connect everything modern devices that you would like to have at home. For this you need three-phase input, that is 380 V. It consists of three lines that redistribute the total load. As a result, with intensive consumption of three-phase power, the load is distributed equally to each of the phases. Therefore, if you want to electrify your home to the maximum, you must first figure out whether your current is single-phase or three-phase. If this is the last option, then there is no problem. Such input is available in almost all new houses. It is approximately 14-20 kW for input, that is, a sufficiently large number of household appliances is permissible. However, with regard to old buildings, as a rule, there is only an aluminum cable with a load capacity of only 4 kW.

Let's see what is 4 kW at home. According to the standard in a residential apartment on square meter usable area needs lighting 15 to 25 W. Let's say the area of ​​the apartment 100 m2, take the average 20 W: 100X20=2000 W. It's already 2 kW. And it's just light. For example, if you wished to have heated floors in the bathroom and kitchen, then this is a plus 100 W per 1 m2. So what else 20 m such floors - here's more 2kW. As a result we have 4 kW, and, it turns out, nothing more can be connected. But it's simply impossible. Now everyone has a computer that consumes about 500 W, a washing machine that takes about 2 kW! The dryer will take its 2.5 kW, dishwasher 2 kW, oven - 4-6 kW, hob - 6 kW. How about without a kettle? The kettle will "eat" its 2.2 kW, so that, in general, one can type and 15 kW and more. So, first of all, when you are going to install another electrical appliance, find out what input cable you have. If it is single-phase, then count on normal work there is nothing. We will have to contact the housing and communal services with a request to allocate additional capacity.

What if you want more?

If possible, then you will receive a permit in your hands, and pay for the corresponding work. This means that an additional cable with the required cross section will be connected to your apartment. Professionals themselves will determine the diameter of the section, that is, it will be clear what load the cable will withstand. All these actions will need to be coordinated with city structures. And this, of course, is not so easy. Not only will you have to run through various authorities and spend a certain amount of money to obtain a permit, but it may turn out that the city will simply have nowhere to find additional capacity. Most power grids have existed for a long time, they are already operating at full capacity, and no one has calculated the additional load before. True, the power can be found in the region. In this case, a cable is pulled to your house, and inside there is a new trunk power cable. Through it, additional power enters the apartment. No matter how serious it may sound, the work is quite simple. You may not even need to scrape anything. After all, you can always use existing embedded channels. By the way, you should not contact public utilities bypassing official authorities, hoping to save time and money. In case of occurrence emergency you will have to bear the responsibility. In addition, all changes will still have to be recorded in the documentation when selling an apartment. You can contact the relevant organizations with questions about the work and coordination, but you will have to pay for it.

By the way, there is another important point. In rooms with high humidity(in the bathroom or in the kitchen) you need to install the so-called fifth wire. This is a potential equalization system that eliminates unnecessary potential on all current-carrying metal elements: bath, sink, case washing machine. These wires must also be brought to the metal risers for supplying hot and cold water. This required condition security. The fifth wire repeats the earth wire, it has a larger cross section.

In older houses, everything is more complicated. If there is a single-phase wire, then there is no grounding in principle. As for the three-phase wires, the current flows through the first wire to the consumption sources, through the second - the current flows back, the third is the ground wire, which needs to be grounded. If there is no grounding in the house, then the third wire will not be useful. Without grounding, there is a direct threat to human life and health. If there is damage in the case, and a person touches it, then the current will pass through the person.

There is a common misconception that you just need to replace the wiring in the apartment with a newer one - and you can safely connect any devices. Actually the throughput 4kW will remain the same. So there is a risk that if you turn on all your amenities at once, the automation will immediately turn off the voltage. More than allowed 4 kW you still won't get it.

By the way, if in the whole house there is no separate protection for each cable extending from individual apartments, then the neighbors begin to depend on each other. There is a main cable at the entrance. A branch is drawn from it, and a circuit breaker is mounted, which controls the amount of electricity for each consumer. An electric meter and an introductory circuit breaker are installed for each apartment. If it does not work, and the network is overloaded, the entire trunk cable will fail, so it is very important that the individual circuit breakers are in order. Although most of them have been working for a very long time, so the risk increases every year.

Note to owners of apartments in old houses

There is a limit on the power of equipment in houses with old wiring. For example, in houses where electric stoves are installed, they can only be about three burners, because the wires will not withstand a heavy load. In houses to which gas is supplied, only gas stoves and cooktops.

Connecting devices in ordinary apartment must be carried out according to the instructions for use, by service specialists. For each device, a water supply tap or a separate outlet of installed power is mounted, an individual power line and a safety switch are made. The diameter of the wires and the data of the safety switches correspond to the power consumption of the equipment (it can be found in the data sheet). If we connect a device of greater power than usual (a stove, for example), then we need to check whether the electric meter can withstand it. If not, then you will have to deal with the utilities to install a new electricity meter. After that, an individual power line is made that is not related to the old network.

For power units of power plants, as well as for all other electrical installations and apparatuses, apply various conditions work. The total maximum power at which several units (or one) can operate continuously is the installed power. The indicator is used for both consumption and generation of electricity.

The concept of installed and estimated capacity

The installed power corresponds to the nominal values ​​and is a fixed technical indicator of the installation or system. For enterprises, it can be regulated, for example, by decommissioning part of electrical installations. This value is used to characterize:

• a separate enterprise and building;
• industry group;
• geographic area and the whole country.

The value of the installed power is understood as an active power indicator or full.

One of the fundamental factors during the design of an electrical installation is the calculation of the power required for its long-term and uninterrupted operation. When they determine what the rated power is, they mean exactly this value.

The values ​​of installed and rated power are interconnected when performing various design work. The value of the rated power is usually determined on the basis of the installed power (i.e. the sum of the rated powers of the consumers of electricity available in the considered part of the electrical installation) after taking certain factors for the simultaneous inclusion of these loads.

Peak power is the highest average load measured or calculated over a specific period of time (for example, within a day, week, month, year). Most often, the period covers one year.

Important! The peak power indicator is the basis for the selection of power equipment in terms of heating by the operating current, determines the settings of the applied protection.

At the design stage, it is usually assumed that the design power is equal to the peak, and a fixed power factor is taken.

The design power is determined based on the following dependencies:

• maximum rated current:

I \u003d P / √3 x U cos φ.

• tg φ \u003d Q / P;
• estimated total power:

S \u003d √ (P² + Q²).

Installed capacity for power plants

For power plants, the installed power is calculated by summing the power ratings of the individual generators and associated motors. These values ​​are almost always identical. In cases of discrepancy, the calculation is carried out at a lower power.

As a result, at expensive stations with big savings fuel, the cost of electricity is extremely dependent on the mode of consumption. Therefore, for large plants, it is advantageous to use the installed capacity for a maximum of hours per year, and for small gas turbines with high fuel consumption, it is more expedient to switch on during peak hours of load, when total time little work on an annual basis.

Estimated capacity of residential buildings

The installed power in a residential building is determined on the basis of the sum of the consumer rated powers of all electrical appliances and installations, and the calculated one, taking into account the expected coefficient of simultaneity of their inclusion.

Each subscriber has an act of delimitation, in which the installed capacity and the calculated one are recorded. For houses and apartments, these values ​​\u200b\u200bare different. Three phases are usually supplied to houses and some apartments, which makes it possible to increase the consumed (calculated) indicator. Single-phase input significantly limits consumption. The load is controlled by protective equipment detuned from the maximum possible currents.

1. If there is no power plant in the house or apartment, the calculated energy is determined by the formula:

P1 \u003d Rmax + M x Rchel, where:

• Pmax - the power of the largest receiver installed in the apartment,
• M is the number of inhabitants,
• Rchel - estimated power per person (for example, 1 kW);

Important! This formula does not take into account the heating of residential premises.

1. Rated power of the power cable apartment building is made taking into account the number of apartments:

P \u003d P1 x n x k + Ra + Pl, where:

• n - number of apartments,
• k is the simultaneity coefficient (it ranges from 0.6 to 0.8),
• Pa - installed capacity of administrative power receivers,
• RL - elevators.

If there is no data, then Pa is taken equal to 0.5 kW, Pl = 20 kW.

1. With electric heating, Ro = P + K1 x ΣRkv, where:

• P - rated power without electric heating,
• K1 - the coefficient of simultaneity of the heat load in n apartments,
• Rkv - heating energy in one apartment, kW.

Important! Precise definition rated power required for space heating requires detailed calculations which are carried out jointly with builders and building designers. IN residential buildings with prevailing heating elements cos φ = 1.

1. The calculated power indicator for a group of buildings is found by the empirical formula:

Pz = 0.95 x k x ΣP, where P is the energy for one building.

Estimated capacity of public buildings

1. In general, for public buildings the formula is applied:

P \u003d Rgr x k x a, where:

• Рgr - installed power of a group of receivers in kW,
• k is the simultaneity factor for this group,
• a is the rated power utilization factor for a given group of receivers.

Both coefficients are in special tables.

1. Taking into account the electricity demand factor, another expression is used:

P = Kc x Rgr, where Kc is the demand coefficient (determined according to the table).

The value of Kc for non-residential facilities ranges from 0.2-0.4 to 1.

In the demand factor method, the calculated load does not depend only on the number of installed receivers. This is due to different demand factors. For large objects with a lot of different equipment, smaller values ​​of Kc should be taken.

In non-industrial buildings: offices, schools, hospitals, theaters, hotels, etc., where lighting receivers and heating devices dominate, it is assumed that cos φ = 1.

Estimated capacity of the utility building (boiler rooms, pumping stations) must be determined on the basis of the manufacturer's catalog data electrical devices planned for installation, in accordance with the following formulas:

1. reactive power of one receiver:

Q1 = tg φ x P1.

1. for a group:

Q \u003d Kc x Qgr, where:

• for Qgr, all calculated values ​​of individual receivers are added,
• Кс is the demand coefficient.

1. active power indicator for the group:

P \u003d Kc x Rgr.

1. general power:

S \u003d √ (P² + Q²).

Important! Based on the given power values, tg φ for the group is calculated: tg φ = Q/P. If its value is greater than that specified in specifications connection, a decision is made on reactive power compensation.

For transformer substation, from which residential and utility buildings will be fed, the calculated power is determined by:

S \u003d √ (P² + Rz² + Ros²) + (Q² ​​+ Qz² + Qos²), where:

• P and Q - indicators for public utilities buildings;
• Rz and Qz - for residential buildings;
• Ros and Qos - for street lighting installations.

Estimated power for industrial facilities

Estimated power industrial enterprise depends on:

• product type;
• technologies used;
• expected maximum load during a year;
• product type;
• type of equipment and degree of its adaptation to technology.

There are many calculation methods, all of them must have common properties:

• ease of calculation;
• versatility in determining loads for different levels consumption and distribution of energy;
• accuracy of results;
• ease of determining the indicators on which the method is based.

The main indicators are calculated using the same formulas, but with different correction factors.

For three-phase electric motors, the installed power is:

Р \u003d Рн / (η x cos φ), where:

• Rn - nominal power indicator from the data sheet;
• η is the efficiency of the electric motor;
• cos φ - power factor.

An increase in the allocated, according to the technical conditions, power must be agreed with the power supply organization. For this purpose, recalculations are carried out for incoming cables and protection devices based on the new installed capacity. But the decision to allocate depends on the availability of free capacity.

After buying a home on the secondary real estate market, first of all, the new owners, as a rule, change the wiring. In the process of this, it turns out that with the replacement of the introductory circuit breaker not so simple. If for the installation of the same type of model it is enough to call the electricians of the company providing services, then for the connection of AB with a large rated current, it is required to submit an application so that the allocated power of electricity is increased. Detailed information on this issue is provided below.

What is "allocated power capacity"?

To explain the meaning of this term plain language, then the allocated (or allowed) power is the maximum allowable load on the consumer's network. It is established in accordance with current regulations and is indicated in the power supply contract.

Those who want to understand this issue in detail should have an idea of ​​the connected, installed, one-time and permitted power. Let's give short definition each of them:

• Attached, this term means the total installed capacity of all electrical receivers powered from the consumer's network.
• Installed- specified in technical documentation to electrical equipment, that is, one in which consumer devices will operate in normal mode.
• One-time – calculated value power consumption of electrical installation equipment for a certain time.
• Dedicated (allowed)- the maximum one-time power that the consumer can connect to the grid of the power supply company. This parameter is indicated in the technical specifications for the connection of energy receiving facilities and in the contract between the consumer and the organization supplying electricity.

What is the danger of exceeding the permitted power?

At the moment, when the maximum load is exceeded, the electric company enters the mode of consumption limitation. The reason for this is a violation of the obligations prescribed in the energy supply agreement. As a rule, consumption limitation is a shutdown electric current. The algorithm for sending such a notification is shown in the figure.

After 10 days, after sending the notice, the company performs a power outage. To avoid this, the consumer must eliminate the violation within ten days, and then contact the service provider to draw up an appropriate act. Electricity supply will be resumed after the electric company has paid a penalty in accordance with the contract.

More serious consequences may arise if, in addition to violating the amount of allocated energy, an accusation of uncontrolled consumption of electricity is brought. The basis for this will be the removal of seals from the introductory machine. You can get more detailed information about the consequences of uncontrolled electricity consumption, electricity metering rules, etc. on our website.

Rules and Regulations

The electrification of any facility is carried out in accordance with the specifications developed by the company providing electricity services. In one of the paragraphs of this document, the parameters of the allocated power for the consumer's network are indicated. The power supply company forms the specifications on the basis of the declared capacity, justified by calculations.

When electrifying residential and public buildings, they are guided by SP 31 110 2003 and temporary instructions PM 2696 01. According to these documents, residential buildings belonging to the 1st category are not standardized in terms of power output. That is, if there is technical possibility, then such objects are formed on the basis of the submitted application.

For residential buildings of the 2nd category, two electrification standards are provided:

1. 5 - 7 kW, for private house or an apartment with gas stoves.
2. 8 - 11 kW - with electric stoves.

In this case, the lower threshold for power release is provided for small apartments in houses under construction under the social housing program. Note that these standards were established relatively recently; for electrical installations of residential facilities built before 2006, they were lower.

How to find out how much power is allocated?

Those who do not know the amount of permitted power for a house or apartment can use the following methods to obtain information:

1. Get a certificate from the power supply company. It should be borne in mind that such a service is considered paid, for example, in Mosenergosbyt, you will have to pay from 1.3 to 3.1 thousand rubles for it, depending on the category of a residential facility.
2. Search for the required parameter in the power supply contract or technical specifications.
3. Obtain information empirically by looking at input parameters protective device. The fact is that in most cases, in addition to its direct functions, it plays the role of a power limiter. To set its maximum value, it is enough to know the operating current of the machine.

The figure shows a diffuser with a working current of 32 A (I nom). Therefore, the maximum allowable load power can be calculated by the formula: P max \u003d U x I nom x 0.8; where U is the rated voltage of the network. Therefore, 230 x 32 x 0.8 ≈ 5.5 kW.

Of all the options presented, the most reliable is the first, especially since a certificate will still be needed if it is planned to increase the allocated power (it is included in the package). required documents).

A calculation based on the operating current of the introductory machine should not be trusted too much. Some models of modern electronic counters have a built-in load relay. In such cases, the rated current of the machine may be overestimated.

Calculation of the required power

This calculation will be needed to understand whether the amount of allocated electrical power for an apartment or house will be sufficient. To do this, you will need to calculate the maximum load by summing up the relevant parameters of all electrical installations of the consumer. Moreover, it is necessary to take into account all household electrical appliances that can be turned on at the same time.

As a rule, all necessary information indicated on a sticker affixed to the equipment case or provided in the documentation. In the event that the sticker has become illegible, and the technical passport has been lost, you can use the table, which shows the typical active power of household equipment.

After calculating the total consumption, do not rush to consider the work completed, you need to add a reserve, taking into account the possible increase in load over time. As a rule, the size of the reserve is set at 20-30% of the calculated parameters.

By adding these two values, we get a result that can be compared with the allowed power. If it turns out to be less than the calculated loads, it makes sense to think about applying for an additional 1 kW or 3 kW. Details on the connection of additional kilowatts will be discussed below.

How to increase the allocated power?

Unfortunately, the norms of electrical energy consumption do not keep up with the growth of active load. In residential premises, more and more household power receiving devices appear, the simultaneous operation of which causes the thermal protection of the input AB to operate. There are only two ways out of this situation:

1. Reduce household consumption by refusing the one-time operation of a piece of equipment, which may introduce some discomfort.
2. Contact your electricity supplier for additional capacity.

Since consuming less electricity is not an option, the latter option is the most rational. Consider how to increase the amount of electricity to individuals and legal entities. Let's start with the first.

For a private person

The algorithm of actions can be conditionally divided into the following stages:

1. Preparation of necessary documents.
2. Drawing up a project for the electrification of a residential facility.
3. The process of coordinating the developed project with the company providing services for the possibility of technological connection or increase in electric power.
4. Project approval in local authority Energy Supervision.
5. Inspection of the electrical installation with the subsequent preparation of an appropriate report and an admission certificate confirming the readiness of the facility for operation under the new conditions of power supply to power receiving installations. The report is compiled by an employee of the electric company, the act of admission - by a representative of Energonadzor.
6. The completed documents are sent to the electric company, after which it increases the amount permissible load(released power).

Now we list the package of necessary documents, they are almost identical to those needed when connecting electricity:

As a rule, the company involved in the development of the project simultaneously offers services for its implementation. In some cases, it makes sense to use their help so as not to waste time.

For legal entities and enterprises

Technically, the procedure for allocating additional capacity for legal entities and private traders is practically the same. The difference lies in the package of necessary documents. For example, instead of identity documents, it is necessary to prepare constituent documents.

Each certificate, contract, photocopy of a document, etc. must be certified by the round seal of the consumer enterprise and the signature of the responsible person.

Important to know:
