Who needs it?
It is obvious that electricity consumption is uneven.
In order to somehow reduce the costs associated with maintaining equipment and encourage users to create a uniform load throughout the day, experts suggested that residents install a three-tariff electricity meter. The wave-like nature of electricity consumption is reflected in the operation of the electrical substation: in the morning and evening it operates at full capacity, during the day at the optimal level, and at night it is practically inactive. As a result of an unevenly distributed load, wear of mechanisms accelerates, and therefore operating costs increase.
Benefits of a three-zone meter: how to save on electricity
The three-zone metering device has a fairly simple operating principle. Different rates apply for the three segments of the day. It remains to figure out what the benefits of using the system for several tariffs are.
What are the benefits of three-tariff meters:
- At night, the fee is charged at a rate that is several times less than the daytime rate;
- You can save approximately 20% of daytime rates in half-peak zones.
Savings are achieved by transferring the main load to night time. It is at night that they do the washing, heat the water in the boiler, and charge electrical appliances. So the benefit is obvious not only for consumers, but for the power plant, removing the load from it.
The difficulty of such savings concerns the implementation of all night procedures. It is not always possible to carry out all manipulations with technicians at night. This way of life is suitable for people who do not have a stable work schedule and who do not need to get up early.
Transition to multi-tariff electricity meters: tariffs and metering
Anyone can switch to a multi-tariff system. This can be a household user or a legal entity. The need to switch to a three-tariff system will require a sound assessment of electricity consumption at night.
With two-zone metering, the night tariff is 50-60% less than the day tariff. With three-zone metering, night energy can be three times cheaper than daytime energy
Stages of transition to a multi-tariff system:
- You need to fill out an application and take it to the electrical network office at your place of residence. In Moscow, you should contact Mosenergo.
- The application indicates the consumer’s contact information and the required type of payment.
- Based on the application, an agreement is created under which paid services for meter installation and parameterization are provided. The user purchases the meter independently.
- After payment for services, the meter is installed. The user is transferred to a new tariff calculation.
Next you will need to select estimated tariffs. You can switch to a two-tariff system or a three-zone system. To determine, you will need to carry out calculations for each type of tariff. You will need to multiply the tariff coefficient for a certain time of day by the value of the tariff rate.

How to count using a three-tariff electricity meter
To benefit from installing a three-zone control unit, it is necessary to take into account the tariff and time of electricity consumption. Let's consider what the price is set at Mosenergosbyt for a time interval according to a three-tariff meter for 2022.
Rates | Moscow | Urban population using electric stoves | Gardening, market gardening, summer cottage non-profit organizations of citizens | Other consumers |
from January 1, 2022 to June 30, 2019 | ||||
T1 (peak) | 6.57 | 5.25 | 5.47 | 6.57 |
T2 (night) | 1.95 | 1.37 | 1.95 | 1.95 |
T3 (half peak) | 5.47 | 4.37 | 4.54 | 5.47 |
from July 1, 2022 to December 31, 2019 | ||||
T1 (peak) | 6.57 | 5.58 | 4.97 | 6.57 |
T2 (night) | 2.13 | 1.5 | 2.13 | 2.13 |
T3 (half peak) | 5.47 | 5.58 | 4.97 | 6.57 |
Let's look at how to calculate electricity using a three-tariff meter. The algorithm of actions is as follows:
First you need to take readings T1, T2 and T3 from the electric meter, which are displayed on the device display at intervals of approximately 30 seconds.
Please note that numbers up to the decimal point are taken. Take readings from the previous period or primary data if the device was installed last month. Calculate the difference of each time interval, that is, from the T1 of the current month you need to subtract the T1 of the previous month, proceeding accordingly with the remaining tariffs. The result must be multiplied by the rate established in your region. We multiply each indicator of energy consumed per month by the tariff. At the last step, add all three numbers to get the amount due for the month. If you have benefits, they are deducted from the final result.
For example, the owner lives in Moscow, his supplier is Mosenergosbyt. In the current period the following indicators were collected:
- T1 – 9546;
- T2 – 9426;
- T3 – 10264.
The following data was submitted in the previous month:
- T1 9413;
- T2 9047;
- T3 9848.
We calculate the energy consumed:
- T1: 9546 – 9413 = 133 (kW);
- T2: 9426 – 9047 = 379 (kW);
- T3: 10264 – 9848 = 416 (kW).
We calculate the cost of each daily zone in the current month:
- T1: 133 kW * 6.57 rub. = 873.81 rub.;
- T2: 379 kW * 1.95 rub. = 739.05 rub.;
- T3: 416 kW * 5.47 rub. = 2275.52 rub.
We get the amount due for the current month:
873.81 + 739.05 + 2275.52 = 3888.38 (r.)
The calculation shows that the consumer used most of the energy during half-peak time, when the tariff is 17% lower than the main one, so the benefit from using a three-tariff meter is low. If he used most of the power at night, the savings would be significantly higher.
How to choose an electricity meter to save money
We tell you which electricity meter to choose in order to optimize the cost of paying for utilities.
When to change the meter
The service life of a household electric meter is from 24 to 32 years. The device must be changed in the last month of this period. If this is not done, the testimony will be considered invalid and you will be fined.
The electric meter for an apartment undergoes a technical condition check at least once every six years. If a specialist detects a breakdown, the device will have to be replaced. Every 16 years, a metrological verification is carried out - a comparison of the real error with the passport data. Any deviations will also be a reason to purchase a new meter.
In 2012, a law was passed that allows the use of only meters with an accuracy class of 2.0 or higher. Old-style devices continue to work, but during scheduled maintenance, inspection and after the expiration of their service life, they are replaced with new ones.
If the consumer himself discovers that the meter is broken, he needs to contact the regional energy company. You can change the device at your own request - if you want to install an electronic model with data transmission over a mobile network and other functions.
Main characteristics
Operating principle
Induction
A home electricity meter is also called a mechanical meter. It contains two coils that create a magnetic field. They rotate a disk, which sets the dial in motion. The design is simple and reliable - such meters are inexpensive. But the accuracy is low - at low loads the readings are greatly underestimated.
Electronic
The meters are equipped with microcontrollers. Their sensors measure current strength and voltage, calculating power consumption. The resulting numbers are recorded in the device’s memory and displayed on the screen. Electronic meters are accurate and offer more useful features, but are more expensive and require more repairs.
Number of phases
To understand which electric meters to choose, look at the cable that connects your house or apartment to the distribution board. If it has two wires, you need a single-phase device that operates at a voltage of 220 V. If you see four wires, feel free to buy a three-phase meter that can withstand a voltage of 380 V.
Three-phase meters are more often used in houses and apartments with high energy consumption - more than 5 kWh at a time. They are needed if you use particularly powerful appliances: an electric stove, a boiler and an oven.
Rates
Choosing a home electric meter depends on what hours you use the most energy. If consumption is uniform, it is better to install a single-tariff meter. With it you buy electricity at the same price, without discounts or surcharges.

Two-tariff electricity meter
The increasing introduction of energy-saving technologies into the everyday life of modern people allows today every prudent consumer to receive maximum cost savings when operating a standard set of household electrical equipment. An important step towards the practical use of various energy saving techniques in everyday life can be the replacement of traditional electricity meters for energy consumption with modern two-tariff devices.
Using two-tariff electric meters will allow you to achieve significant cost reductions when paying your electricity bills. In the case of differentiated (by time of day) metering of consumed electricity, its cost at night (from 11 pm to 7 am) is calculated at a reduced tariff.
The use of such a schedule for metering electrical energy in our homes is explained by the special operating mode of electrical substations, the consumer load on which continuously changes throughout the day. The maximum load at substations occurs in the early morning hours (from 7 to 9 o'clock), when the bulk of industrial enterprises begin work, as well as in the evening (from 18 to 23 o'clock), when people return home from work and load the network with switched on household appliances. devices. After 11 p.m., the load on electrical networks and substations is noticeably reduced.
Such an abrupt loading schedule of electrical networks has an extremely negative impact on the technical condition of electrical equipment used in substations and on power lines. In addition, with such an operating mode, the consumption of industrial raw materials (coal) used in the generation of electrical energy at thermal substations and the total volume of harmful emissions into the atmosphere significantly increase. Thus, with a carefully thought-out and well-balanced loading mode of substations and electrical networks, it is possible to significantly reduce the amount of energy resources consumed, reduce the cost of repairing electrical equipment and reduce environmental pollution with harmful emissions.
Pros and cons of using
We have already figured out how the accrual system works in a three-zone counter. Now let's look at what positive and negative sides it has.
The advantages include:
- cost savings when used during non-peak hours;
- legality of use, which does not include fines, shutdowns and other troubles that may arise when using prohibited methods of saving;
- saving the readings on the meter display for the entire period of use. Nothing bad will happen even if the receipt is missing.
In addition to the positive qualities, like any device, there are also disadvantages:
- not all people are accustomed to using household appliances at night;
- there is a risk that after installing such an expensive device, the electricity supplier company will revise its tariffs over time and make your purchase unprofitable;
- Costs increase greatly during peak hours, and many people have a direct need to use energy at this time, which can make its payback a very long process.

Disadvantages of two tariff meters
After installing the meter, you need to carefully study your daily routine. To be more precise, all manipulations associated with electrical devices must be transferred to the night, otherwise the device will simply be useless. This means that you need to load the washing machine, turn on the heating devices or charge them only after turning on the low tariff.
Before installing a dual-mode meter, you should know the tariff rates applicable in your area, as they can vary significantly even in neighboring areas. If the discount is only 10-20%, the device can be called unprofitable; it will pay for itself in at least 5 years. If you are satisfied with these conditions, you can proceed to purchase and install the meter.
When thinking about lowering your energy bills, it's easier to save money than changing your tariff plan. It is widely believed that a two-zone tariff only pays for itself when most of the energy is used during off-peak periods. But most users - both companies and households - use energy when it is more expensive.
Cost of equipment
The amount you will have to pay for installing a new device includes several cost items:
- The cost of the equipment itself. Prices range from 5,000 to 15,000 rubles. Even if the budget is limited, it is advisable to choose not the cheapest samples, but focus on the average price category.
- Payment for installation. The regional power grid will charge approximately 3,500 rubles for installation of equipment.
- Associated costs for servicing the device. Even with proper operation, you will have to allocate funds for:
- primary programming, which is carried out only by specialists;
- calling the team again to make adjustments to the program in case of changes in light tariffs;
- mandatory periodic verifications;
- replacing the batteries that power the device's memory. It is impossible to do this on your own; you will need the help of specialists.
Instructions for switching to a two-tariff meter
When the decision to switch has been made, you can replace the old electric meter with a new device.
To do this, the following algorithm of actions is observed:
- Submit an application to the regional energy sales company for installation of a two-tariff meter in person, or through your personal account on the official website.
- Purchase a suitable multi-tariff meter.
- Pay for services to replace the electric meter.
- Within 10 working days, an employee of the energy sales company will come and take readings from the old meter, dismantle it, install a new one, put it into operation and seal it.
- Sign a certificate of completion of work on commissioning, a service agreement.
You can buy an electric meter directly from the energy sales company itself, which often provide this opportunity and offer two-tariff meters. It is prohibited to independently dismantle an old metering device or break seals and is punishable by a fine.
The essence of multi-tariff accounting
It's no secret that electricity consumption differs at different times of the day. Some people use it during the day, while others use it at night. In this regard, meters have been developed that will relieve the power supply during the evening rush hour and thereby increase the reliability of the power supply as a whole.
Who installs
The installation of devices is carried out by representatives of regional operators. For example, in Moscow the regional operator is Mosenergo. Replacement of the meter is carried out on a paid basis. To do this, you need to submit an application to the regional operator, pay the cost of the device and the work of the specialist. After which the specialist goes to the installation site and makes all the necessary settings.
Regulatory acts
The obligation to install an electric meter is regulated by Federal Law on Energy Saving No. 261-FZ dated November 23, 2009, Federal Law No. 102-FZ dated June 26, 2008, as well as Government Decree No. 442 of the Russian Federation dated May 4, 2012.
Time zones
This period lasts from 23.00 to 07.00. At this time, the best rate applies. If a citizen works late, then it is more profitable to use the division of consumed energy into several phases. With electric stoves, in this case, you need to cook as much as possible at night in order to consume less energy during the day.
To save money when establishing this mode, you need to connect devices with high power only during the specified period. Morning is characterized by increased activity in the use of networks, as at this time many citizens get ready for work.
In addition, there are two half-peak zones, which last from 10.00 to 17.00 and from 21.00 to 23.00. These intervals occupy the most significant period during the day. The cost of energy in this case is determined by average indicators, provided that a three-phase meter is installed in the apartment.
Important! If the premises are equipped with a two-phase meter, the calculation is made according to the daily tariff
Cost of day and night tariff
The indicated values are taken into account only by those who use a multi-tariff device in their apartment. If a single-tariff meter is installed, the calculation is made at a single tariff
In this case, the time of day is not taken into account.
With a gas stove at home, you don’t have to spend money on installing a new meter and pay for energy at one tariff, since this device contributes to significant savings.
What are the savings?
The transition to two-tariff consumption metering would be clearly beneficial if the daytime zone tariff was equal to the standard one, called single-rate. However, this is not so - it is not profitable for suppliers to provide electricity in this way and they make the “daytime” tariff more expensive than usual. Are the savings real in this case, and what calculations need to be made to determine them?
In order to find out whether it would be profitable to install a two-tariff meter in an apartment, you need to take the energy consumption profile. It will reflect how much electricity is consumed in a certain period of time. To do this, you need to record meter readings at 7:00 and 23:00 for a month, distributing them into separate columns, for example, “day” and “night”.
In our example:
- the daytime zone established in the region lasts from 7 am to 11 pm, its tariff is 3 rubles 50 kopecks per kWh of energy;
- the night zone is calculated at 2 rubles per kW-hour;
- The standard one-rate tariff is 3 rubles 20 kopecks.
Thus, if the apartment has a two-tariff electric meter, during the daytime you will have to overpay 30 kopecks for each kWh of energy. But the saving during the night period is 1.50 rubles. It turns out that for equal profitability, for every kilowatt spent at night, there should be 5 kilowatts “boosted” during the day. The ratio that allows us to find out how much electricity needs to be spent at night in order for two-tariff metering to become profitable for us is called the night consumption threshold.
In our case it is 1/(1+5) ≈ 0.17. This means that two-rate tariffication is justified if the night period accounts for more than 17% of total consumption. That is, differentiation is beneficial to us if out of 1000 kW consumed during the month, more than 170 kW was consumed at night.
Let's give a real example. The current single-rate tariff in Moscow is 5.03 RUR/kWh, the peak tariff (when differentiated by two zones of the day) is 5.57 RUR/kWh, and the night tariff is 1.43 RUR/kWh.
We carry out calculations: 1/(1+(5.03 – 1.43)/(5.57-5.03)) = 0.13,
and we learn that the threshold for night consumption in Moscow is 13%. It is very beneficial, since this share can be more than covered by starting the washing machine after 23 hours.
For comparison, let’s calculate this indicator in the Samara region, where the single-rate tariff is 3.17 RUR/kWh, the peak “daytime” tariff (when differentiated by two zones of the day) is 3.19 RUR/kWh, and the night tariff is 1.57 r/kWh
The nighttime consumption threshold is 1/(1+(3.17-1.57)/(3.19-3.17)) = 0.01 or 1%.
As we see, in this case, two-tariff metering is always to the advantage of the consumer, since even an ordinary refrigerator operating around the clock “rewinds” more than 1% of total consumption.
To calculate the threshold for night consumption when differentiating between three zones of the day, the formula would have to be significantly more complicated, but Russian suppliers make this task much easier. In almost all regions, the half-peak zone tariff (from 7:00 to 10:00 and from 21:00 to 23:00) is equal to the standard single rate.
Thanks to this, the “half-peak” can simply be removed from the calculations, and the calculations can be carried out in the same way as for a two-tariff meter. For example, in the Samara region, the peak zone tariff is 3.53 RUR/kWh, the half-peak tariff is 3.44 RUR/kWh, and the night tariff is 1.73 RUR/kWh. Accordingly, the night consumption threshold is:
1/(1+(3.44-1.73)/(3.53-3.44)) = 0.05 or 5%.
Soviet-style electricity meter
Maintenance of multi-tariff meters
When talking about costs, we cannot help but touch on the topic of appliance maintenance. All three-tariff meters are complex electronic devices, which, before commissioning, are not only connected to the power system, but also programmed - for each dial, the time range during which it must record readings is entered.
Obviously, only specialized employees can perform such procedures. A three-tariff meter, like a standard recording device, needs to be checked every 16 years.
These devices are designed with lithium batteries that retain the settings in the event of a power outage. Their performance is hardly sufficient for the time interval between checks. Therefore, be prepared that in the middle of the term you will have to call specialists to replace the batteries.
Rating of TOP 3 popular models

Electric meter SEO-55 two-tariff
The SEO-55 electric meter does not differ in technical characteristics from the Mercury. Under this brand, two models are produced, designed for different loads: Sh-50 (50 A) and Sh-60 (60 A).
"Energomera SE-102"
The device can be reprogrammed for eight tariffs. The device allows you to exclude 32 days from the interval during which energy consumption readings are calculated. The meter is supplemented by a display, which displays information about the voltage value, the level of power consumption, the current tariff and other information. The supported software also allows you to program an automatic transition from winter to summer time.
How much to pay
Electricity consumption standards at the regional level are calculated according to an established algorithm. All subjects of the Russian Federation themselves approve these indicators, depending on the economic development and characteristics of a particular place. The basis is the amount of energy resources provided over twelve months per inhabitant. The average per month is calculated by dividing the amount of costs by 120 thousand (multiplying the number of citizens by twelve months).
This indicator can change both up and down. How this number is calculated depends on:
- the number of people registered in the housing and the number of rooms;
- the presence or absence of water heating devices;
- equipment for cooking (gas or electric stove);
- location of the house or apartment (village or urban settlement);
- climate of the region;
- deterioration of the housing stock.
Based on all this, the standards for electricity consumption per person are calculated based on the following components:
- number of people living in the apartment;
- the rate of electricity consumption in a given region;
- an energy tariff that corresponds to a specific type of consumption.
As a result, all these indicators are multiplied and the price per kilowatt is obtained, which is indicated in payment receipts for electricity. The Housing Code takes into account circumstances when, with formally installed meters, electricity charges are charged at average rates for the outgoing six months:
- meters in the premises do not work or do not meet established requirements;
- data for electricity is not transferred by the resident to the resource supply company;
- the consumer does not allow the representative of the organization to visit the flow meters more than twice.
You need to understand that management organizations carefully monitor cases when residents do not have registration in the apartment and metering devices are not installed. All information about such persons is immediately sent to law enforcement agencies.
Payment for general house needs
Property owners must also pay for the maintenance of common areas. In this case, the norms of electricity consumption per person are calculated based on the readings of general house flow meters and the presence of metering devices in the apartment or house. The consumption of provided energy resources in a building in which individual meters are installed is calculated as follows:
- for premises with individual flow meters - add up the indicators of the metering device in the apartment and the costs of general house needs in the amount of 7 kW/h for each person per month;
- to calculate electricity without a meter - sum up the number of kW/h calculated according to the standard and the indicator of unallocated kilowatts in proportion to the square footage of the living space.
To motivate people to switch to calculations using flow meters, every six months the norms of electricity consumption per person will increase by 15-20 percent. In this way, electricity tariffs will increase along with the annual planned increase in utility prices. All this will hit the pockets of users, so it will be expensive to pay for light at the average tariff when there is no electric meter. It is more profitable to install a flow meter, and in a few months its purchase will fully pay for itself.

Operating principle of a three-tariff meter: metering time
A three-tariff electric meter calculates electricity for three different periods of the day. So daytime starts at 7 am and ends at 11 pm. For daily accounting, generally accepted tariffs are used. Multi-tariff devices divide daytime into two zones: peak and half-peak. The peak zone covers the time from 7 to 10 am and from 5 to 9 pm. At this time, the highest energy consumption is recorded, so tariffs will be quite high.
The half-peak zone begins at 10 am and lasts until 5 pm, and from 9 to 11 at night. The night period begins at 11 am and lasts until 7 am. This is the most profitable time, because then the cost of a kilowatt is halved. It is night time that is the most economical.
For household use, it is recommended to purchase two-tariff meters. Manufacturing enterprises should choose three-tariff metering devices. It is better to postpone the main load on the power grid at night, thereby reducing costs. So at night you can start washing, heat the house, heat the water with a boiler. But when choosing a meter, there are many factors to consider. The choice of device depends on the climate, type of stove installed, category of users and other criteria.
Two-tariff electricity meters: how to choose - find out which one is better in terms of characteristics
Sooner or later, the moment always comes when you need to think about replacing your electricity meter. There are many reasons - an old meter may outlive the period set by the manufacturer, become unusable, cease to meet the requirements of an existing or modernized home electrical network, or simply not fit into the apartment interior. There is another reason that encourages owners to decide to replace this device - a differentiated tariff system for electricity consumption.
Two-tariff electricity meters: how to choose
That is why two-tariff electricity meters have become increasingly in demand among consumers; how to choose which will be recommended in this publication.
What is a multi-tariff accounting system
It is known that electricity consumption varies significantly at different times of the day. Energy engineers conventionally divide day and night into five successively replacing one another zones:
- Night - with minimal consumption, lasting from 23.00 to 7.00
- Morning peak – from 7.00 to 9.00. The population wakes up en masse, prepares to go to work, a huge number of electrical appliances are turned on, and work shifts at enterprises begin.
- Daytime semi-peak, from 10.00 to 17.00 – consumption levels out somewhat due to a decrease in the “home” load, but remains quite high due to the work of a large number of enterprises and institutions.
- Evening peak – from 17.00 to 21.00. “Rush hour” on all types of electric transport, consumers returning home with the understandable mass switching on of lighting, heating or air conditioning systems, computers, televisions, all types of household appliances, including very energy-intensive electric stoves, boilers, washing machines and dishwashers.
- Evening half-peak, from 21.00 to 23.00, when the total load on the power grid begins to gradually decrease due to the end of household chores and the gradual transition of the population to sleep.
On the graph you can clearly see the approximate level of electricity consumption, based on statistical data from one of the largest cities in Russia - St. Petersburg.
Graph of daily load distribution in the city power grid
Such load surges have an extremely negative impact on the condition of power lines and, most importantly, on the operation of power plants. By and large, this leads to irrational use of energy resources, accelerated wear and tear of generating and transforming equipment, and even to a certain deterioration of the environmental situation in the region.
In order to smooth out such differences as much as possible and minimize the consequences of such jumps, a system of differentiated tariffication of consumed electricity was developed. The main goal of this approach is to extremely motivate the population to reduce consumption during peak load hours and transfer many energy-intensive household processes specifically to the so-called “night slack”.
This policy has been introduced in many regions of Russia, although the established tariffs can vary quite significantly by region and city. But the night rate is always much lower than the day rate.
For example, in St. Petersburg, from January 1, 2015, the following cost per 1 kW of consumed electricity is established (the cost per kilowatt is indicated in brackets for houses where stationary electric stoves are installed and (or) electric heating of the premises is provided):
Tariff type | cost of 1 kW, rub |
General, in the absence of meters with separate metering of consumption by time | 3,53 (2,47) |
Daytime, for half-peak and peak zones when using multi-tariff meters, from 7.00 to 23.00 | 3,55 (2,49) |
Preferential night, from 23.00 to 7.00 | 2,14 (1,50) |
Differentiated electricity tariffs for 2015 in St. Petersburg
In some regions, in particular Moscow and the Moscow region, there is even the possibility of three-level tariffs with a division of half-peak and peak zones:
Tariff type | cost of 1 kW, rub |
General, in the absence of meters with separate metering of consumption by time | 4,68 (3,28) |
Daytime, for half-peak and peak zones when using two-tariff meters, from 7.00 to 23.00 | 4,91 (3,44) |
Daytime for peak zones, from 7.00 to 10.00 and from 17.00 to 21.00, when using meters with multi-level tariffs | 4,92 (3,45) |
Daytime for semi-peak zones, from 10.00 to 17.00 and from 21.00 to 23.00, when using meters with multi-level tariffs | 4,08 (2,85) |
Preferential night, from 23.00 to 7.00 | 1,26 (0,88) |
Differentiated electricity tariffs for 2015 in Moscow
Even a quick glance shows that the cost of “night” and “peak” electricity can sometimes differ by almost four times. And if you sit down with a pencil in your hands and a calculator (computer) to analyze your home consumption, you can achieve very significant savings.
So, for example, you can do all the washing at night - modern washing machines allow you to program this process with a delayed start. The same can fully apply to dishwashers. If you have a powerful boiler at home, then it is also better to heat the water at night, creating a supply of hot water that will last for a day. Modern “smart” kitchen appliances are quite capable of preparing a hot breakfast for the owners, having completed all manipulations before 7 am. It can provide good savings and rational use of heating or air conditioning devices, taking into account the “intelligent” capabilities inherent in them. And for a fairly large category of people who belong to the “night owls”, such pricing is, in general, just a godsend.
In a word, a two- or multi-tariff consumption metering system opens up a wide range of opportunities for serious savings. However, first you will need to make a material investment - purchase an appropriate meter.
Use the calculator to calculate the electricity consumption of your refrigerator.

Parameters for selecting a meter with separate tariffication
Before you start choosing an electricity meter with separate pricing, you first need to find out exactly whether a differentiated payment system operates in a particular locality. A multi-tariff meter costs much more than a regular meter, and therefore its purchase should be justified.
Moreover, it is also necessary to clarify the number of tariff levels - as we have already seen in the above example, there may be two or more. It is possible that this gradation may increase even more - for example, with separate accounting on weekdays and weekends or even by seasons - similar experiments are being carried out, and in some places in European countries this has already been implemented. Some models of modern meters have a fairly large technological backlog - the electronic circuit allows you to program their operation with separate accounting in 8 or even 12 different modes.
Type of meter based on operating principle
All electricity meters can be divided into two large groups - induction and electronic.
Until recently, all meters were induction
Induction meters are familiar to everyone - they were the ones that were installed everywhere until recently. The consumed current passing through the coils of the metering device created an electromagnetic field, due to which the disk connected to the mechanical counting device rotated. Each revolution of the disk corresponded to a certain amount of energy consumed.
Electronic meters have a different operating principle. Semiconductor elements of the circuit convert the passing current of a certain voltage into a pulse signal, which is transmitted to the counting device.
Electronic pulse counter with electromechanical indication
The indication can be provided electromechanically - the same wheels with numbers as on an induction meter, but with rotation transmitted through a stepper electric drive that responds to impulses generated by the circuit. Another, more modern option is an electronic digital display.
Electric meter with digital display
It is quite clear that multi-tariff meters can have an exclusively electronic operating principle and digital display. By the way, this limits them by location. Liquid crystal displays require a certain “microclimate” to operate correctly, and in conditions of low temperatures or direct sunlight they may simply stop displaying information, although the meter circuit itself will properly calculate consumption. Therefore, if you plan to install a new meter in a private house, you should plan to place it exclusively indoors.
Meter accuracy class
This indicator indicates the permissible error of the device, expressed as a percentage. The vast majority of induction meters belonged to the “2.5” class. Electronic devices in this regard are, of course, more accurate, and have classes “2”, “1”, “0.5” and even higher.
The accuracy class is always indicated both in the technical documentation and on the device itself - usually a pictogram is used in the form of a number enclosed in a circle.
The accuracy class of the device and other important electrical parameters are always indicated on the front panel
Of course, the higher the accuracy class, the more expensive the device. And here it is important to know one subtlety so as not to overpay when buying too much. Electricity network workers may unreasonably demand the purchase of a meter with inflated indicators - “1” or even “0.5”. However, there is a legislative act on this matter that clearly establishes the requirements for such devices. In the Decree of the Government of the Russian Federation No. 442 of May 4, 2012, which regulates retail electricity markets, it is determined that for private consumers, citizens living in multi-storey apartments, private houses, an accuracy class of “2” or higher is established. Class “1” is required only at the entrance to a multi-apartment residential building or if the total load power exceeds 670 kW, which simply does not happen in private housing.
There is one more nuance. The same Resolution (Article 142) established that even if the meter standing in the apartment at the time of adoption of this document has a lower accuracy class, then its replacement will be mandatory only after the expiration of the test interval or if the device fails (or is lost) .
Demands from electric network workers to replace the meter with a more accurate one, class “1”, or within a previously established period, without the desire of the homeowner, are illegal.
Single-phase, three-phase, maximum current
Most city apartments and private houses are connected to a single-phase network of 220 V, 50 Nz. Accordingly, the meter must meet these indicators. However, there are also connections to a three-phase 380 V network, for example, in apartments with stationary electric stoves or electric heating systems provided for by the design of a particular building. This will be indicated by special sockets and plugs on the cables of powerful electrical appliances, which differ from the usual connection points.
Socket and plug for powerful electrical appliances powered by a three-phase network
In such cases, you will have to select a three-phase meter. By the way, many private developers often create a kind of “energy reserve” by immediately connecting their homes to a three-phase network - this significantly expands the possibilities of using household appliances and powerful power tools in the future. Many models of modern three-phase meters can be connected to work with a single-phase network, which significantly increases their versatility.
For each meter, the rated and maximum load current indicators are determined. As a rule, they are designed for a maximum permissible value of up to 60 A, which approximately corresponds to a total load of 10 kW - this is quite sufficient for almost any private home with a large margin. If the calculation shows that the total power consumption is above 10 kW, then you should purchase a meter with a maximum current value of 100 A. Such devices have a direct principle of connecting to the network, without additional converters. If, however, a load exceeding 100 A is planned, then it will also be necessary to connect the meter through a special device - a current transformer.
Voltage, rated and maximum current indicators are also always indicated in the device data sheet and on its front panel.
Availability and type of communication interfaces
Further prospects for the development of power grids include the introduction of automated consumption metering systems, and in some regions the practical implementation of such developments is already underway on an experimental basis. Communication channels are organized, transmitting first to local stations, and then to a single center of meter readings, including for other types of consumed resources (water, gas). The power lines themselves (via PLC modem), IP or GSM networks can be used as feedback channels.
In any case, it would be a good idea to ask your local energy supply organization about planned upgrades so that, if necessary, you can purchase a meter with a similar function built into it, so that you don’t have to buy another one when putting such a system into operation.
Additional meter options
Modern electronic meters, in addition to separate tariffs, may have a number of other additional options. These include entering monthly consumption indicators into memory cells, which can be convenient, for example, when conflicts arise with energy supply organizations. In some cases, this data can be transferred to a computer. Some meters can be used to take instantaneous indicators - consumed current, voltage or active (reactive) power at a specific point in time, thus performing the function of a multimeter. The built-in “event log” can reflect peak consumption points, power surges or lack thereof, attempts and time of opening the device, phase changes, exposure to an electromagnetic field and other actions.
As practice shows, most of the built-in functions for the average consumer remain unclaimed.
Varieties by type of installation
When choosing a meter, be sure to take into account its design features regarding the method of its installation in the distribution board.
All old metering devices were installed using standard screw fastenings at three points - the top and two bottom. For this purpose, mounting holes or brackets with standardized distances between them were provided on the devices themselves, and on the panels there were corresponding threaded sockets or places for screwing in fasteners.
Placing mounting holes for mounting in old-type panels
Some electronic meters are produced in housings that are designed specifically for this type of installation. This is the best choice if an old design switchboard is installed in the apartment (entrance).
The panels have appropriate holes for fastening
A more modern option for mounting a switchboard with a metering device is installation on a DIN rail. In this case, on the back of the meter there is a shaped groove with clamps, with the help of which it is attached to a standard profile metal rail.
The counter will be installed on this DIN rail
Some models provide the possibility of both types of fastening. In addition, the same electronic circuit of a metering device can be housed in different housings. For example, the fairly popular two-tariff meter SOE-55 is available in four versions, with housings from “1” to “4”, which differ in appearance, dimensions, and mounting method.
Curved grooves with a lock for mounting on a DIN rail
When constructing private housing or during major renovations in an apartment, preference is increasingly being given to modern plastic boxes for external or built-in (wall-mounted) placement, with mounting of meters, circuit breakers, RCDs and other devices on DIN rails.

What to pay special attention to when buying a meter
- First of all, the “golden” rule should work here - never, under any circumstances, purchase such devices from random people, in markets or in obscure organizations that do not have the appropriate state certification. No matter how favorable the terms of purchase may seem, no matter how convincing the sellers are and how they show certified product passports, such a deal should be resolutely rejected. Moreover, you should not even consider the issue if it is proposed to purchase a used device.
Probably the most reasonable approach to this issue would be to contact your local energy sales organization. They will probably either offer to purchase a meter from them, or they will tell you which manufacturers’ models are recommended for installation. Very often, such information is posted on the official websites of electricity supply companies.
- The selected meter model, regardless of whether it is domestic or imported, must be on the State Register list, that is, it must be fully certified and approved for sale and operation on the territory of the Russian Federation.
The completeness of the device must be checked according to the passport
- When purchasing a meter, be sure to check its completeness - original packaging, electronic parts, housing with fasteners, technical data sheet of the product with a specific factory serial number.
- Attention is immediately drawn to the presence, safety and clarity of factory seals. If you suspect a violation, you should take another product.
Particular attention to the technical form of the product with all the necessary marks
- When reading the technical documents accompanying the meter, the date of manufacture of the product, the established warranty periods and, of course, the inspection interval are checked. The technical form must contain a quality control mark for the product.
- The operating instructions for the device should clarify the permissible modes of its operation - this is especially important when the switchboard is planned to be installed in an unheated room.
- to install the meter yourself - for this it is better to invite a specialist with permission to perform this type of work. In any case, after installing the device, it is mandatory to call employees of the energy supply company, who must check the correct connection, register it, carry out their own sealing of the device, configure it in accordance with the current tariff policy, give the owner detailed instructions on the rules for taking readings and other important questions regarding the operation of a specific model. The installation of the meter is also noted in its technical form, indicating the date for its next verification.
Popular models of meters with differentiated tariffs
In conclusion, without pursuing any advertising purposes, but only as an example, here are several models of meters with multi-tariff metering functions, which are quite popular and have earned positive reviews from both electricity consumers and specialists.

Who will benefit from a two-tariff meter?
From the calculations above, it is clear that a two-tariff meter allows you to save money. But not everyone will benefit from this method.
A two-tariff flow meter is needed in the following cases:
- A person actively uses electrical appliances and turns on the lights at home after 11 pm. For example, he comes home after work at 10 pm. If the whole family goes to bed before 11 pm, then a two-tariff meter will not be profitable, because the main electricity consumption will be calculated at an increased daily tariff.
- The apartment has many electrical appliances (including heated floors), and the chandeliers have ordinary incandescent light bulbs. In this case, a lot of electricity is consumed, and the benefits of using a two-tariff electric meter will be noticeable. If at home you only have a refrigerator, a washing machine and a TV that rarely turns on, then the savings will be insignificant.
- In a private house, electricity is required to operate heating, hot water and lighting systems. Moreover, heating boilers consume a large amount of electricity. But cottage owners have the opportunity to control the operation of boilers using a timer and start them only at a certain time (after 11 pm).
If a person leads a nocturnal lifestyle, then he will be able to experience the benefits of installing a two-tariff meter.
In all other cases, the benefit will be in question, since you will have to pay extra for installing the meter. Installation of the simplest two-tariff electricity meter according to Mosenergo tariffs will cost almost 4 thousand rubles. Prices may vary in other regions.
Economic benefits from installing two-tariff meters
Economic benefits from installing two-tariff electricity meters, myth or reality.
An electricity metering system differentiated by time of day provides residents with the opportunity to pay for electricity at night, at a tariff that is cheaper than the daytime rate.
In order to take advantage of this saving , you need to install a two-tariff electricity meter.
The fact is that power plants operate in two main modes: peak and reduced.
Maximum energy consumption occurs in the morning hours ( 7-10 a.m.) when most enterprises begin to work and in the evening hours ( 7-11 p.m.), when most people return from work and turn on household electrical appliances: lighting, televisions, electric kettles, electric stoves, irons, washing machines, etc.
At night, electricity consumption drops sharply. Such a “ragged” rhythm of work has a bad effect on the service life of power plant equipment. Significant amounts of money have to be spent on equipment repairs.
In addition, the consumption of energy resources (coal, oil, gas) for generating electricity is less when the load is uniform. This means that equalizing the operating mode of power plants will save valuable natural resources. And their savings, in turn, are a contribution to improving the environmental situation. After all, by reducing consumption, we also reduce the share of harmful emissions into the atmosphere. Every ton of coal saved is almost two tons of carbon dioxide (CO2), which is known to cause the greenhouse effect. And reducing greenhouse emissions is a guarantee of preventing climate change on the planet.
To equalize energy consumption and reduce the burden on the environment, it is necessary, if possible, to turn on energy-intensive household electrical appliances, such as dishwashers and washing machines, at night. In many European countries this practice has long been accepted.
And to make this profitable, in many countries, including Russia, night electricity tariffs are much cheaper.
Advantages and disadvantages.
If the apartment does not have electricity meters installed, then the monthly payment for light is calculated as follows: the consumption standard (how many kWh is consumed on average during this period) is multiplied by the tariff (the cost of one kWh). The standard depends on a number of criteria: the number of rooms, the type of stove (electric, gas), the number of floors of the building, whether it has an elevator, the number of registered residents in the apartment. The old induction meters that are still installed in most apartments are single-tariff, that is, they count electricity consumption around the clock at one price - in St. Petersburg it is 3.84 rubles for rooms with gas stoves and 2.69 rubles for apartments with an electric stove , but for night time (from 23 to 7 o’clock) there is a special tariff, which is almost 45 % more profitable, and only new electronic two-tariff or multi-tariff meters can take into account the “day” and “night” tariffs separately.
One of the disadvantages of old single-tariff induction meters is the incorrect calculation of electricity consumption at a load above the rated load, and the rated load on old meters is exceeded everywhere. Indeed, recently the number of powerful electrical appliances in apartments has increased significantly and continues to grow.
Another disadvantage is obvious - it is an increased danger. When using an old meter, especially with a load in excess of the rated one, there is a high risk of its failure and electrical wiring fire. Therefore, savings on replacing old electrical equipment in an apartment can cost a pretty penny over time.
A two-tariff meter looks the same as a regular meter, only the display with readings changes at set hours. Electronic two-tariff meters not only meet modern requirements and standards, but also have exceptional accuracy; the error of individual models of electronic meters reaches 0.5%.
New two-tariff meters are compact, have a number of additional functions, such as displaying current power consumption, “remembering” the results of the previous billing period, remote reading of indicators using digital interfaces, as well as other useful additions. They last an average of 25-30 years, and help save electricity, and therefore your money.
Along with the advantages of the new meters, they also have disadvantages:
- If a regular meter costs about 600 rubles, then a multi-tariff meter costs about 1,500 rubles. and higher.
- In addition, such a meter itself is a very complex device with autonomous power supply from a lithium battery. The period between state verifications of such meters is 16 years, the same as for single-tariff meters, but most likely, before this period the lithium battery will need to be replaced.
Since this is an electronic device, there is a possibility of it failing in the event of a complete power outage in your home, in this case, if you purchased the device yourself, then replacing and purchasing a new one falls on your shoulders, but if you purchased and installed the device through a management company , then you have a 5-year warranty.

conclusions
The issue of saving electricity is a pressing issue in many families due to high electricity tariffs, an increase in the number of household appliances and an increase in overall electricity consumption. The result of consumption is visible in the receipts that are received once a month for electricity.
How effective is the transition to a multi-tariff metering device? Calculations show that consumption at night is about 30% of daily consumption, making the transition relevant.
The problem is that it is not always possible to provide such a load at night. The transition is relevant if the apartment or house has powerful electrical consumers that provide room or water heating, night lighting, air conditioning systems, electric heating, boilers and other equipment.
If the apartment has a standard set of appliances (washing machine, microwave, TV), there is no point in switching to a two-tariff meter.
How to choose a two-tariff meter
Two-tariff electricity meters differ in the following indicators:
- single-phase and three-phase;
- measurement accuracy class;
- maximum power of electricity;
- number of zones served by the device;
- presence or absence of a remote data transfer function;
- type of fastening (bolts or DIN rail);
- display features;
- types of additional functions.
Attention: stores offer multi-tariff meters that allow you to separate the recording of readings by day of the week. These devices can be used if the supplier also presents different tariffs depending on the specified parameter.
For private houses and apartments, whose residents can consume more than 500 kW per month, it is impossible to install a single-phase electric meter, since such buildings require a three-phase connection.
Also, before choosing a metering device, you need to find out what maximum load level the network can withstand. On average, electrical appliances installed in apartments produce no more than 10 kW. For such cases, standard meters with a permissible value of 60 A are suitable.
If preliminary calculations show that the total power will exceed 10 kW, then the conventional electric meter should be changed to a 100-amp one. In this case, we are not talking about benefits, but about the need to protect the general network from overload.
