Two-tariff electricity meter: reviews. How to calculate electricity by a two-rate meter?

The device for accounting for the consumed electricity (meter) is an everyday and obligatory subject in any house, private or multi-apartment building. Increasingly, in homes and enterprises, obsolete electric meters "with a swiveling disk" are replaced by an electronic meter of a new generation - a two-rate electricity meter. The responses of citizens who have already switched to separate accounting of the consumed electricity are quite contradictory.

An impressive part of electricity consumers says a fairly quick payback of the installation of a two-rate meter: the term is from 6 to 18 months. Nevertheless, negative reviews are also found. The main claim - the two-rate accounting system did not justify itself and proved to be less profitable than the energy supply companies said. Why is this happening, and how much can the installation of such a device as a two-tariff meter be justified?

Two-tariff counter - what is it?

The electronic two-tariff meter of the electric power concerns to devices of the account of power resources of new generation. The functions of the counter of this type allow you to keep a separate account of the consumed electricity based on the time of day when the consumption occurred. Why do we need this function?

Energy companies have long noticed the "zonality" of electricity consumption. The main "peak" of energy costs is traditionally accounted for in the morning and evening - at this time people, going to work or returning home in the evening, use the maximum number of lighting appliances and household appliances. The minimum electricity consumption occurs at night. Such "fluctuations" create inconvenience to energy companies, forcing them to work with additional load during peak hours. And it was with the goal of somewhat "unloading" energy companies that schemes for multi-tariff and two-rate accounting were invented.

Two-rate accounting is that the day is conditionally divided into "daytime" and "night" time. At the same time, electricity consumed "at night" is paid at a price lower than the "day". Thus, it becomes beneficial for citizens to adjust the operating time of their household energy-consuming appliances a little.

For what periods of time are recorded on a two-rate counter

With a two-tariff electricity metering schedule, the days are distributed as follows:

• Daytime zone - the period from 7:00 am to 11:00 pm.
• Night zone, respectively - from 23:00 to 7:00 h.

Who benefits from installing a two-rate counter

So, the system of two-rate accounting, which the energy companies offer, at first glance is quite simple and profitable. Providers of electricity, "selling" at night electricity at a price lower than during the day, partially compensate for this difference, slightly overstating the cost of electricity at the "daily" rate. Then why are all owners of residential and industrial premises in no hurry to switch to two-rate meters? There are several reasons. One of them is the usual Russian "running around with documents," with which not everyone has the time and the desire to deal. Another reason why owners of premises most often are afraid to install a two-rate electricity meter is the responses of people who claim that the "day / night" tariff has not justified itself or pays off very slowly.

What is the reason for the appearance of such reviews? The main thing that should be known to those who are only planning to install a two-tariff electricity meter: people's feedback on the benefits and time of payback of switching to such a scheme of accounting in different regions is significantly different because of the difference between "daily" and "night" tariffs established Energy companies in each region. So, for example, in the Russian capital and the region the price of a kilowatt for the urban population in the daytime is 5.57, at night - 1.43 rubles. Such a tangible difference makes the installation of a two-rate meter incredibly profitable.

Another example: if a citizen lives in the rural area of the Volgograd region, the ratio of day / night for 2016 will be 2.81 / 2.01 rubles. In this case, the difference is not so felt. And if you take into account that in the daytime a citizen "overpays" for electricity with respect to a one-tariff scheme, the benefit of installing a two-tariff meter is rather doubtful.

Therefore, before installing a two-tariff electricity meter, it is worthwhile to clarify the difference between the day and night tariffs and decide for yourself whether it is worthwhile to switch to a similar accounting scheme.

How to set a two-rate counter

The process of transition to a two-tariff system of accounting for spent electricity is in fact much simpler than is commonly believed.

The first step is to buy an electronic meter with the function of setting two tariffs. It is best to purchase the device directly from a specialist called to replace the old meter with a new one. If, for some reason, the owner of the premises wants to purchase the meter on his own, then it is necessary to do this exclusively in a store that specializes in the trade of meters.

The next step is to obtain a resolution in the energy supply company for the replacement (installation) of the electricity meter. Only after receiving this document can you call a specialist who will install the meter.

The obligatory final stage of setting a two-tariff meter is the call of a specialist of the energy supply company. He must adjust, adjust and seal the installed meter, make appropriate notes in the technical passport. In addition, the specialist can give the necessary instructions regarding the operation of the meter, the timing of verification and the reading of the meter.

What documents are required to install a two-rate counter

To switch to a two-rate accounting system it is necessary to provide the following documents to the energy supply company:

• Passport.
• Previously signed a contract with the energy company; After switching to a two-rate accounting of electricity, the contract is renewed.
• Documents confirming ownership of the premises where the meter will be installed.
• The application (the form and sample application, as a rule, are provided by a specialist of the power company).

Which meter is best to choose for living space

What should I look for when buying an electronic two-tariff counter?

Before buying, you need to make sure that the purchased meter is authorized for use in the Russian Federation (that is, this model is included in the state register) and, which is also important, corresponds to GOST.

Be sure to check on the technical passport completeness, the presence in the passport of the factory serial number, the date of issue, the calibration interval and the warranty period, the presence and integrity of all mandatory factory seals.

Another important indicator is the accuracy class. For private houses or a separate apartment the accuracy of a 2nd class device is quite permissible, for a multi-storey house, class 1 is established by law.

Another question that is often asked by people who purchase electricity meters are two-rate: "Which is better - imported or Russian production?" Until recently, preference was often given to meters registered in European countries. But for today there are a lot of Russian factories producing two-tariff electricity meters, reviews of which characterize their products perfectly. These include, for example, the Moscow plant of electrical measuring instruments supplying the counters of the SOE-55 line, the Stavropol company Energomer, which produces meters with the same name, or NPK Incotex, the manufacturer of the popular Mercury meter brand. And this is far from a complete list of Russian producers, who have proved themselves in this field.

Determine the choice of the model best with the help of a specialist supply company - he can tell which models of metering devices are recommended for installation.

Single-phase or three-phase - what's the difference?

Another issue that may arise during the installation of a two-tariff meter: purchase a single-phase or three-phase meter. The difference is that single-phase meters are designed for installation in a room where 220 V power is supplied. These include an ordinary city apartment, a private residential or country house, a personal garage or a small retail outlet.

For electric networks with a voltage of 380 V, a three-phase electricity meter is required. A two-tariff electronic metering device that meets this requirement, is suitable for private large houses and cottages, businesses, large private or industrial garages, in short, for any room with increased electricity consumption.

The main advantage of a three-phase meter is that, unlike a single-phase meter, it can fully work both with a voltage of 380 V and in networks with a voltage of 220 V. Thus, a three-phase two-tariff electricity meter is in some way a universal option for most Premises.

When to take readings of meters

After the procedure for installing the meter has been completed completely, it is necessary to understand how to take readings from a two-tariff meter correctly and in a timely manner in order to avoid overpayment, fines or incorrect charging.

Specialists of energy companies are most often recommended to take monthly meter readings in the same period - the last day of the current month. This regularity allows you to monitor the consumption of electricity and provide the supplier with timely information.

How to correctly read the electricity readings for the month

The two-tariff meter is read as follows:

• It is best to have a separate notebook (notepad) for reading the meter for consumed electricity.
• On the display of the meter, the indication is indicated by the letter "T" and the numbers 1-3. Time period "day" corresponds to the indicator "T1", the night period is indicated on the display as "T2". Both figures are written out in the notebook.
• Important! Not all the digits on the display are fixed, but only the meter reading, which means kW. The figures separated by a dot (border, highlighted in contrast color, etc.) indicate the fraction of kVT - this indicator is not fixed or the rounded first digit after the point is written out.

How to calculate electricity consumption by a two-tariff meter

Calculation of electricity by a two-rate meter is as follows:

• From the readings of "T1" for the current month, the previous readings of "T1" are subtracted. The result is multiplied by the price of kW at the rate of "day".
• From the testimony of "T2" for the current month, the previous readings of "T2" are subtracted. The result is multiplied by the price of kW at the "night" tariff.
• If for each tariff the energy supply company sends a separate receipt, the results are entered in the "daily" and "nightly" receipt, respectively. In case if payment is made on a single receipt, the amount for the day and night tariff is entered in the general receipt and when the payment is summed up.

We fill in the receipt

If, for the convenience of the client, the energy supplier monthly sends a receipt with the completed requisites and ready settlement, then the only thing that is required to complete such a form is the meter's meter readings for the current month.

If the receipt of the receipt is made by the owner of the premises on his own, it is not enough just to know how to calculate the electricity by a two-rate meter yourself, you need to correctly and in detail fill out the receipt for payment:

• In the receipt all necessary columns are filled.
• In the column "Branch (name) of the bank, account of the beneficiary, personal account" the bank details are indicated, in which the energy supplying company opened the account, the account number of the electricity supplier, the code and the MFI. All this information is contained in the contract with the energy company.
• In the column "Surname, initials, address", the payer enters his data.
• In the table "Electricity" is entered the month for which payment is made. Then filled in line: the current "final" readings "T1", the previous readings "T1", "daily" tariff (kW / h), the amount payable in rubles and kopecks. Similarly, in the next line, the data for the night tariff "T2" is filled: the current "final" readings of "T2", the previous readings of "T2", the "night" tariff (kWh), the amount payable in rubles and kopecks.

It is necessary to pay attention that in the article the standard form of the receipt is given. For various electricity suppliers, the form of the payment receipt may vary slightly. If questions arise during filling out, you need to contact the specialists of the energy supply company for explanations.
