Calculation of the 3rd price category. Electricity price categories

If in the first and second price categories, calculations were made only for electrical energy (which automatically included the cost of power consumption), then calculations in the 3,4,5,6 price categories are carried out for both electrical energy and power. However, the price of electricity can be significantly lower than in the first or second price category.

In order to understand the difference between 3.5 and 4 and 6 price categories, it is necessary to clarify that the tariff for the service of transmitting electricity through electric networks is about 50% of the total final price of electricity for any price category. It is approved by the local executive authority in the field of state regulation of tariffs and can be divided into the following types:

1. One-piece;
2. Two-part.

As is clear from the name of the tariff type, a single-rate tariff is set for each kWh. transmitted energy and includes all costs of transporting electricity. The two-rate tariff is divided into a rate for electricity and a rate for capacity and in total also includes all costs for transporting electricity.

When choosing a particular tariff for the provision of electricity transmission services, the consumer chooses the possible price categories applicable to him. If he has chosen a single-rate tariff for the provision of electricity transmission services, he can then choose 1, 2, 3 or 5 price categories. If it is a two-part one, then only the 4th or 6th price category (more details about the procedure for choosing a price category are discussed in the corresponding section of the site).

But let’s return to the order of calculations in the third to sixth price categories: calculations for electricity in these price categories are made for each hour separately, and calculations for power are made for the value as a whole for the month.

The question arises of how the volume of electricity consumed for each hour of the month is determined and how to determine the amount of power for the month as a whole.
Regarding electricity, everything is very simple - there are multi-tariff meters that store in their memory the hourly electricity consumption for several months. You only need to transfer its readings to the computer via the infrared port or using a flash drive and all the data will be on hand.

It is worth noting that in accordance with the amendments made by Decree of the Government of the Russian Federation dated May 4, 2012 No. 442, the procedure for calculating power and its cost for the 3rd and 5th price categories differs from the procedure for the fourth and sixth price categories:

Power consumption at a certain hour is the electricity consumption for that same hour. For example, from 19-00 to 20-00 your electricity meter showed consumption of 5 kWh, which means your power consumption at that hour was 5 kW.

For the third and fifth price categories, power is calculated very simply: on working days of the month, electricity consumption at the reporting hour is taken (these hours are published on the website of ATS OJSC and the website of the State Enterprise - automatic telephone exchange peak hours loads), then this consumption is summed up and the resulting amount is divided by the number of working days in a month (arithmetic average). This power is offered at the purchase price from the wholesale electricity market increased by a percentage of the sales premium. For convenience, we will call it capacity paid to the wholesale market.

And for the fourth and sixth price categories, two capacities are calculated: power paid for on the wholesale market and transmitted power. In this case, the power paid to the wholesale market is calculated according to the above principle, and the transmitted power is calculated as follows: on working days of the month in a certain range of hours (for example, from 9 to 11 and from 15 to 20), established by order of the System Operator, the maximum electricity consumption is selected - planned peak load hours for 2014 (or another period), then this consumption is summed up and the resulting amount is divided by the number of working days in the month (arithmetic average). Thus, the transmitted power will always be no lower than the power paid to the wholesale market.
In the examples below it is proposed to consider the calculation procedure for 3 - 6 price categories.

In this article we will look at each price category and what it consists of. Read about how to choose the most favorable price category.

What are electricity price categories? - These are options for the electricity tariff of the guaranteeing supplier. The price category is chosen by the consumer himself; the final price of electricity for the consumer largely depends on the correctly chosen price category.

Our company’s specialists are ready to check for free the optimality of the selected price category for a specific consumer, for this you need.

Price categories are tariff options for the consumer; previously there were two of them (single-rate and two-rate), but now there are six. You can read in detail what the price of electricity consists of. The price category determines how the price of electricity and power purchased by the supplier is included in the final price and what is included in the price, as well as whether the consumer will need to plan hourly consumption a day in advance (price categories 5 and 6), this is clearly seen in.

When choosing price categories, there are some restrictions, for example, consumers with a maximum power of energy receiving devices of more than 670 kW are prohibited from choosing the first and second price categories, and for consumers who are powered directly from generators, only the fourth and sixth are generally available, as well as for consumers connected to FGC UES networks. Check out.

It is also important for the consumer to remember that they need to choose a price category within 30 days from the date of publication of electricity transmission tariffs, usually this happens at the end of December.

Let's take a closer look at each of the price categories to understand how they differ:

First price category

The price for purchasing power on the Wholesale Electricity Market is already taken into account in the price of electricity, so the consumer pays for the entire volume consumed per month at one price, one line on the electricity bill. Electricity transmission is included in the price at a single rate tariff. This price category is available only to small consumers, with a maximum power receiving device of less than 670 kW.

Second price category

Power is also included in the price of electricity as in the first category, however, the bill will have two or three prices, depending on which option of the second price category was chosen by the consumer, it can be two-zone (day/night) and three-zone (peak/half-peak/night ). Transmission is also taken into account at a single rate tariff; the price category is also not available for consumers over 670 kW.

Third and fifth price categories

In all price categories except the first and second, electricity is paid hourly; the electricity bill has two lines - electricity and power. Read more about what power is. Electricity is charged at different prices every hour, so hourly electricity metering is required to operate at these price points. The transmission tariff is taken into account at a single rate, as in the first and second price categories. In the fifth price category, the consumer is required to plan his hourly consumption a day in advance and pay for deviations; they are included in the price of electricity.

Fourth and sixth price categories

Electricity is paid for by the hour; a separate fee for power is charged, as in the third and fifth price categories. However, transmission is already included in the price at a two-rate tariff, that is, the rate for the maintenance of networks and the rate for losses in the networks are paid separately, while the rate for losses is usually included by the supplier in the price of electricity. Therefore, the invoice usually has three lines: electricity, power purchase and power transmission. “Power transmission” is the payment of a rate for the content of a two-part transmission tariff; read more about how it is calculated. In the sixth price category, just like in the fifth, obligations arise for planning hourly consumption and paying for deviations. These price categories are available to all legal entities - consumers of electricity - without exception.

Price category comparison table

Price category	Pricing Differences
	Purchase		Broadcast
	Electricity	Power	Network losses	Contents of networks
I	Electricity includes the power price and is calculated as a whole for the billing period at one price		the single-rate transmission tariff, the loss rate and the maintenance rate are reduced to one value charged per kWh.
II	Electricity includes the price of power and is calculated separately for each zone of the day (Day/Night or Night/Half-Peak/Peak)
III	The price of electricity is calculated at intervals (different for each hour of the month)	Power is paid for as a separate product, the volume of power is determined depending on the consumer load during peak hours
IV			The rate for losses is multiplied by the amount of electricity consumed per month	The transmission content rate is multiplied by the amount of network capacity
V			Similar to I, II and III price categories
VI			Same as price category IV

The table reflects only those price components that depend on the price category, about all components of the price of electricity.

Example 2: Enterprise with maximum power from 150 to 670 kW, located in the Udmurt Republic. Consumption volume 659,665 kWh: peak - 165,894, half-peak -274,882, night - 218,890

	Electricity price	Electricity cost
2 CC 2 day zones		2 315 424,15
2 CC 3 day zones
		1 952 608,4
		2 130 717,95

* with deviation =5%;** - compared to the highest cost; all payments in rubles excluding VAT

An enterprise can choose any price category. 4CC is optimal. The benefit compared to the first price category is 0.14 rubles/kWh excluding VAT. When switching from the 1CC to 4CC category, an enterprise will be able to save 92,353 rubles excluding VAT per month.

In this case, you also need to take into account that if an enterprise is currently calculating according to price categories 1, 2 or 3, then the calculations use a single-rate tariff for transmission services; in order to switch to calculations under the fourth category, it is necessary to change the tariff to a two-rate tariff. This can be done once a year, after the publication of electricity transmission tariffs.

The above examples clearly show the importance of choosing the right price category, payment for which will be the most profitable.

	It is necessary to install metering devices that allow measuring hourly consumption volumes
Tariff for transmission services
Tariff for transmission services	two-part

According to the law, the choice of price category is the responsibility and right of the consumer of electrical energy himself.” Transition within categories 1,2,3, 5 and within categories 4,6 is possible within a year. To do this, you must notify the guaranteeing supplier 10 working days before the start of the billing period. An enterprise can switch from categories 1,2,3,5 to categories 4 or 6 once a year. To do this, you need to change the tariff for transmission services by notifying the electricity supplier within a month after the date of publication of tariffs for the new period, usually at the end of December.

The main criteria that you need to pay attention to when choosing the optimal price category:

1. Seasonality of consumption, whether consumption schedules are identical in summer and winter. If seasonality is present and the schedule is not uniform, it is necessary to calculate price categories for each season, summarize the indicators and see which price category will bring the greatest economic benefit.
2. The daily consumption profile also influences the choice of price category. So, for example, with a predominantly night work schedule, the second price category will be beneficial.
3. Take into account the tariff for the transmission service at which the enterprise is calculated. When changing tariffs, analyze the profitability of price categories for all possible options.
4. Enterprises with maximum capacity more than 670 kW you can only choose between price categories 3-6. Accordingly, when choosing 5-6 price categories, it is necessary to evaluate the possibility of accurate hourly planning. Savings in categories 5-6 can be achieved by minimizing deviations of the actual volume of deviations from the planned one.
5. Consider the costs of replacing metering devices.

The article was written a year ago, but has not lost its relevance and can be useful at the beginning of the year:

According to the provisions of the current legislation, within 1 month from the date of publication of tariffs:

• consumers of an energy sales organization have the right to choose a tariff option for electricity transmission services (one-rate or two-rate);
• consumers of the supplier of last resort with a maximum power of more than 670 kW choose one of 3-6 price categories ();
• consumers of the supplier of last resort with a maximum power of less than 670 kW choose one of 1-6 price categories ().

Since tariffs are approved by regional energy commissions for the regulatory period (calendar year), the beginning of a new year is the right time to analyze the adopted tariff decisions and select the most cost-effective option from those provided for by law.

What should you do to make an informed choice?

You need to find approved tariffs for the year.

Tariff decisions are published on the official websites of RECs, network organizations and/or guaranteeing suppliers. Depending on your region, they may be easier to find on one of the sites above. For example, let’s find tariffs for 2018 for consumers in the Chelyabinsk region.

We are looking for a ruling or solution on the establishment of uniform (boiler) tariffs... on the territory of the Chelyabinsk region. I found it on the REK website (Resolution No. 71/6 of December 28, 2017).

Once the desired solution has been found, the first thing we pay attention to is the date of its adoption. In our case, this is December 28th. In addition, the REC website states that it was published on December 29. This means that consumers in the Chelyabinsk region can choose a tariff option (price category) until January 29, 2018. In this case, the selected option will be applied from January 1, 2018. The date of publication of decisions is more difficult to find than the decision itself. Therefore, I advise you to focus on the date of its adoption, since most often the date of the decision and its publication coincide or differ by 1-2 days.

It is rare, but it does happen, when a decision is made retroactively. For example, the REC makes a decision with a date of December 29, and publishes it on January 25. In this case, consumers simply will not have time to choose a tariff option until January 29. That is why the law specifies the date of publication.

If there is still time to make a decision, I advise you to make a calculation based on last year’s volumes and current year’s tariffs. AND It is advisable to make calculations for the entire year, and not for one or several months.

Calculation for ESP consumers, GP consumers with a maximum power of more than 670 kW

Since for GP consumers the maximum power is more than 670 kW. it is advisable to choose from 3 or 4 price categories, which differ only in the tariff option for transmission services (you can read why 5 and 6 Central Committees are a priori less profitable), the calculation for them will be identical to the calculation for consumers of energy sales organizations:

For calculation you will need:

• actual volume of consumption and for the previous year with monthly detail;
• approved tariffs for the current year.

As an example, the calculation is given for the consumer of the Chelyabenergosbyt state enterprise, the maximum power of which is from 670 kW to 10 MW, the HV voltage level.

We provide calculations of actual consumption volumes, network and purchased power, and tariffs for electricity transmission services.

As can be seen from the calculation, it is more profitable for the consumer to choose a single-rate tariff for electricity transmission services if he supplies electricity from an energy sales organization / price category 3 if from a supplier of last resort (342 thousand rubles in 2018 tariffs and 2017 volumes).

Calculation for GP consumers with a maximum power of less than 670 kW.

For such consumers, it is advisable to choose from price categories 1, 3, 4 ().

For calculation you will need:

• actual consumption volume and network volume and purchased capacity for the past year with monthly detail;
• approved tariffs for the current year;
• maximum levels of unregulated prices of the guaranteeing supplier.

As an example, the calculation is given for the consumer of the Chelyabenergosbyt state enterprise, the maximum power of which is from 150 to 670 kW, the HV voltage level.

We provide calculations of actual consumption volumes and tariffs for electricity transmission services.

In addition, you need to find on the website of the guaranteeing supplier the maximum levels of unregulated prices published by the GP on a monthly basis (usually located in the section “for legal entities”). On the Chelyabenergosbyt website:

We substitute the values ​​into the calculation.

As can be seen from the calculation, it is more profitable for the consumer to choose 1 price category in settlements with the supplier of last resort (saving 610 thousand rubles in 2018 tariffs and 2017 volumes).

The above information is required to be disclosed by the guaranteeing supplier on the official website. So there shouldn’t be much difficulty in finding it.

Tips for choosing a tariff option/price category:

• If, as in the examples discussed, one sales category is profitable every month for the entire year, naturally you need to choose it.
• If the annual savings from choosing a tariff option are approximately zero, then, according to the resulting data, choosing any of the options under consideration is equally profitable. What should the consumer do in this case:
  • If plans for the current year are more optimistic than the reality of last year (more output, positive dynamics in the markets for raw materials, finished products), it is better to choose a two-part tariff / 4 price category.
  • If, on the contrary, there are fears that another crisis will break out this year, it is better to choose a single-rate tariff / 3rd price category.
• If different tariff options are beneficial for each half-year (for example, in the first half of the year it is single-rate, in the second half-year it is two-rate, or vice versa), you cannot choose a tariff option for half-years in accordance with the law. You need to determine the most profitable option for yourself in terms of annual savings.

In accordance with the Decree of the Government of the Russian Federation No. 442 dated May 4, 2012 “On the functioning of retail electricity markets, complete and (or) partial restrictions on the consumption of electricity”, six price categories of electricity have been adopted within the retail electricity market.

• Integral, that is, applied to the volume of electrical energy consumption for a certain period of time - a day, a month, etc. These prices are based on one bid only.
• Interval, then applied to hourly volumes of electrical energy consumption, where each hour can have its own price. This type of price involves two or more bids.

Integral include the first and second price categories (TsK1 and TsK2)

The interval ones respectively include the third, fourth, fifth and sixth price categories (TsK3, TsK4, TsK5 AND TsK6)

At the same time, consumers are also divided into two types:

1. more 670 kW (consumers > 670 kW)
2. consumers with maximum power less 670 kW (consumers< 670 кВт)

The indicator “maximum power” is the previously used term “connected power”. The term was replaced upon the entry into force of the Government of the Russian Federation Decree No. 442 of May 04, 2012 “On the functioning of retail electricity markets, complete and (or) partial restrictions on the consumption of electrical energy” .

Maximum power is the maximum load corresponding to the simultaneous use of energy receiving devices.

As a rule, the maximum power of the decree is in The act of delimiting the boundaries of balance sheet ownership.

Otherwise, to determine the type of consumer, the maximum hourly consumption volume determined using control measurements is used:

or over the past 5 years

or for the period when control measurements were carried out, if this period is less than 5 years

Introduced on July 1, 2013 ban to choose a price category for electricity for individual consumers. That is, those consumers whose maximum power exceeds 670 kW cannot choose integral type price categories, that is, price categories from 3 to 6 are available to them .

Those consumers whose maximum power does not exceed 670 kW have the right to choose any from six price categories.

All consumers, regardless of the maximum power value, require hourly metering of electricity consumption to apply interval price categories.

It should be taken into account that interval price categories:

1. Divided into:

• prices NOT requiring hourly consumption planning (HCP) are: CC3 and CC4.
• prices requiring hourly consumption planning (HCP) are: TsK5 and TsK6

2. Divided into:

• prices from single bet transmission tariff are: TsK3 and TsK5.
• prices from two-part transmission tariff is: TsK4 and TsK6

It is differentiated only by voltage levels.

Applies to the integral actual volume of consumption for the billing period (per month).

It is differentiated according to two characteristics:

(1) by day zones;

(2) by voltage levels.

It is divided into two-zone (day and night) and three-zone (night, peak and half-peak) prices.

Applies to the integral actual monthly volume of consumption for the corresponding zone of the day.

1. The price category is determined by a group of delivery points (GDP) - by a set of delivery points within the boundaries of the balance sheet of the consumer’s power receiving device (a set of consumer power receiving devices that have electrical connections between each other through power grid facilities owned by the consumer)
2. The wide range of options is just an illusion.
3. The price is a consumer concern. Now he (especially the consumer > 670 kW) can minimize the price only by changing consumption modes, including using his own generation.
4. To do this you now need:

• count: to determine target consumption modes, select a price category and control the calculations of the guaranteeing supplier
• set up hourly commercial accounting: voluntarily to those consumers who<670 кВт для применения ЦК2-ЦК6, обязательно тем, кто >670 kW
• establish hourly technical records and establish regular monitoring and regulation:

(1) the size of the actual power in KO hours and CO hours, so as not to overpay for power when using TsK3-TsK6

(2) the amount of actual energy consumption during expensive and cheap hours, so as not to overpay for “expensive” electrical energy

(3) the size of the reserved maximum power, so as not to overpay for reservation

• establish document flow and reporting to the energy sales organization on:

(1) the value of the declared capacity - once a year;

(2) hourly electricity consumption - daily or once a month, depending on the contract

(3) the amount of actual power per KO hours - monthly

(4) the amount of actual power per hour CO-monthly

(5) the selected CC for the next month - monthly, if the consumer re-selects it every month

• take into account factors affecting the cost of electricity:

Otherwise, overpayment for electricity is guaranteed!
