115. If there are no metering devices at the metering points or the operation of metering devices for more than 15 days of the billing period, the determination of the amount of thermal energy spent on heating and ventilation is carried out by calculation and is based on the recalculation of the base indicator for the change in outside air temperature for the entire billing period.

116. The value of the heat load specified in the heat supply contract is taken as the base indicator.

117. The base indicator is recalculated based on the actual average daily outside air temperature for the calculation period, taken according to meteorological observations of the weather station of the territorial executive body closest to the heat consumption facility, which carries out the functions of providing public services in the field of hydrometeorology.

If, during the period of cutting the temperature graph in the heating network at positive outside temperatures, there is no automatic control of the heat supply for heating, and also if the cutting of the temperature graph is carried out during a period of low outdoor temperatures, the value of the outside air temperature is taken equal to the temperature indicated at the beginning of the cut graphics. When automatically regulating the heat supply, the actual temperature value indicated at the beginning of the graph cutting is taken.

118. In the event of a malfunction of metering devices, the expiration of their verification period, including removal from work for repair or verification for up to 15 days, the average daily amount of thermal energy and coolant determined from the metering devices over time is taken as the base indicator for calculating thermal energy and coolant normal operation during the reporting period, reduced to the calculated outside air temperature.

119. If the deadlines for submitting instrument readings are violated, the amount of thermal energy and coolant determined by metering devices for the previous billing period, reduced to the calculated outside air temperature, is taken as the average daily indicator.

If the previous billing period falls on a different heating period or there is no data for the previous period, the amount of thermal energy and coolant is recalculated in accordance with paragraph 121 of these Rules.

120. The amount of thermal energy and coolant spent on hot water supply, in the presence of separate metering and temporary malfunction of devices (up to 30 days), is calculated based on the actual consumption determined by metering devices for the previous period.

121. In the absence of separate metering or inoperative condition of the devices for more than 30 days, the amount of thermal energy and coolant spent on hot water supply is assumed to be equal to the values established in the heat supply contract (the amount of heat load on hot water supply).

122. When determining the amount of thermal energy and coolant, the amount of thermal energy supplied (received) in the event of emergency situations is taken into account. Emergency situations include:

a) operation of the heat meter at coolant flow rates below the minimum or above the maximum limit of the flow meter;

b) operation of the heat meter when the coolant temperature difference is below the minimum value established for the corresponding heat meter;

125. The amount of coolant (thermal energy) lost due to a leak is calculated in the following cases:

a) a leak, including a leak on consumer networks up to the metering station, has been identified and documented in joint documents (bilateral acts);

b) the amount of leakage recorded by the water meter when feeding independent systems exceeds the standard.

126. In the cases specified in paragraph 125 of these Rules, the leakage value is determined as the difference in the absolute values of the measured values without taking into account errors.

In other cases, the amount of coolant leakage determined in the heat supply contract is taken into account.

127. The mass of the coolant consumed by all consumers of thermal energy and lost in the form of leakage in the entire heat supply system from the thermal energy source is defined as the mass of the coolant consumed by the thermal energy source to recharge all pipelines of water heating networks, minus intra-station expenses for own needs during production electrical energy and in the production of thermal energy, for the production and economic needs of the objects of this source and intra-station technological losses by pipelines, units and devices within the boundaries of the source.

V. The procedure for distributing losses of thermal energy and coolant between heating networks in the absence of metering devices at the boundaries of adjacent heating networks

128. The distribution of losses of thermal energy, coolant, as well as the amount of thermal energy, coolant transferred between heating networks of heat supply organizations and heating network organizations in the absence of metering devices at the boundaries of adjacent parts of heating networks, is carried out by calculation as follows:

a) in relation to thermal energy transferred (received) at the border of the balance sheet of adjacent heating networks, the calculation is based on the balance of the amount of thermal energy supplied to the heating network and consumed by heat consuming installations of consumers (for all owner organizations and (or) other legal owners of adjacent heating networks) for all sections of pipelines at the border(s) of the balance sheet of adjacent sections of the heating network, taking into account heat energy losses associated with emergency leaks and technological losses (pressure testing, testing), losses through damaged thermal insulation in adjacent heating networks, which are documented in acts , standards for technological losses during the transfer of thermal energy and losses exceeding the approved values (excessive losses);

b) in relation to the coolant transferred at the border of the balance sheet of adjacent heating networks, the calculation is based on the balance of the amount of coolant supplied to the heating network and consumed by heat-consuming installations of consumers, taking into account coolant losses associated with emergency coolant leaks, documented in acts, standards for technological losses during transfer of thermal energy approved in accordance with the established procedure, and losses exceeding the approved values (exceeding norms).

129. The distribution of excess losses of thermal energy and coolant between adjacent heating networks is carried out in quantities proportional to the values of the approved standards for technological losses and losses of thermal energy, taking into account emergency leaks of coolant through damaged thermal insulation.

130. In the case of transfer of thermal energy, coolant through a section of the heating network owned by the consumer, when distributing losses of thermal energy, coolant and excess losses of thermal energy, coolant, the specified heating networks are considered as adjacent heating networks.

In accordance with the Federal Law "On Heat Supply", the Government of the Russian Federation decides:

1. Approve the attached Rules for commercial metering of thermal energy and coolant.

2. Federal executive authorities must bring their regulatory legal acts into compliance with this resolution within 3 months.

3. The Ministry of Construction and Housing and Communal Services of the Russian Federation must approve within 2 weeks the methodology for commercial accounting of thermal energy and coolant.

110. The amount of thermal energy and coolant supplied by a source of thermal energy, for the purpose of their commercial accounting, is defined as the sum of the amounts of thermal energy and coolant in each pipeline (supply, return and make-up).

111. The amount of thermal energy and coolant received by the consumer is determined by the energy supply organization based on the readings of the consumer’s metering devices for the billing period.

112. If, in order to determine the amount of supplied (consumed) thermal energy, coolant for the purpose of commercial accounting, it is necessary to measure the temperature of cold water at the source of thermal energy, it is allowed to enter the specified temperature into the computer in the form of a constant with periodic recalculation of the amount of consumed thermal energy taking into account the actual cold water temperature. It is allowed to introduce a zero cold water temperature throughout the year.

113. The value of the actual temperature is determined:

A) for the coolant - by a single heat supply organization based on data on the actual average monthly values of the cold water temperature at the heat source, provided by the owners of the heat sources, which are the same for all consumers of heat within the boundaries of the heat supply system. The frequency of recalculation is determined in the contract;

B) for hot water - by the organization operating the central heating point, based on measurements of the actual cold water temperature in front of the hot water heaters. The frequency of recalculation is determined in the contract.

114. Determination of the amount of supplied (received) thermal energy, coolant for the purpose of commercial accounting of thermal energy, coolant (including by calculation) is carried out in accordance with the methodology for commercial accounting of thermal energy, coolant, approved by the Ministry of Construction and Housing and Communal Services of the Russian Federation (hereinafter referred to as the methodology).

In other cases, the time of lack of water is included in the duration of the emergency situation.

125. The amount of coolant (thermal energy) lost due to a leak is calculated in the following cases:

A) a leak, including a leak on consumer networks up to the metering station, has been identified and documented in joint documents (bilateral acts);
b) the amount of leakage recorded by the water meter when feeding independent systems exceeds the standard.

126. In the cases specified in paragraph 125 of these Rules, the leakage value is determined as the difference in the absolute values of the measured values without taking into account errors.

In other cases, the amount of coolant leakage determined in the heat supply contract is taken into account.

V. The procedure for distributing losses of thermal energy and coolant between heating networks in the absence of metering devices at the boundaries of adjacent heating networks

A) in relation to thermal energy transferred (received) at the border of the balance sheet of adjacent heating networks, the calculation is based on the balance of the amount of thermal energy supplied to the heating network and consumed by heat consuming installations of consumers (for all owner organizations and (or) other legal owners of adjacent heating networks) for all sections of pipelines at the border(s) of the balance sheet of adjacent sections of the heating network, taking into account heat energy losses associated with emergency leaks and technological losses (pressure testing, testing), losses through damaged thermal insulation in adjacent heating networks, which are documented in acts , standards for technological losses during the transfer of thermal energy and losses exceeding the approved values (excessive losses);

B) in relation to the coolant transferred at the border of the balance sheet of adjacent heating networks, the calculation is based on the balance of the amount of coolant supplied to the heating network and consumed by heat-consuming installations of consumers, taking into account coolant losses associated with emergency coolant leaks, documented in acts, standards for technological losses during transfer of thermal energy approved in accordance with the established procedure, and losses exceeding the approved values (exceeding norms).

According to the text published on the Official Portal of draft regulatory legal acts, it is proposed to introduce new Rules for the commercial metering of heat and coolant and invalidate the Decree of the Government of the Russian Federation of November 18, 2013 No. 1034 “On commercial metering of heat energy and coolant.”

You can read the text of the project and write your review about it using this link:

In the text of the new Rules, the Ministry of Construction fixed a list of the main parameters recorded by heat and coolant metering devices:

a) the time of normal and faulty operation of the metering unit during the day;

b) coolant temperature in the supply and return pipelines;

c) coolant flow in the supply and/or return pipelines;

d) the amount of coolant entering the hot water supply system for open heating systems;

e) the amount of water and thermal energy entering the hot water supply system with a separate input (from the central heating point);

f) the volume of coolant used to recharge the heat supply system (if there is a make-up pipeline);

g) coolant pressure in the supply and return pipelines (when installing pressure sensors);

h) the temperature of the coolant used for make-up at the thermal energy source before the point of insertion of the make-up pipeline into the heating network.

In this regard, the following basic requirements for heat metering devices have been established:

1) Metering devices must be sealed so that no one can interfere with their operation. Along with sealing the structure, it is possible to protect measuring instruments by entering a password.

2) The components of a heat meter are a computer and instruments for measuring flow (volume), temperature, and for steam heat supply systems, a pressure sensor. Pressure measuring instruments used in water heating systems are used only for the purpose of monitoring the quality of the coolant.

3) The computer (calculation converter) must be equipped with a standard industrial protocol and interface that allows remote data collection. Remote collection should not affect the metrological characteristics of the heat meter.

4) Measuring instruments that have settings must have non-volatile memory that allows you to save the current settings and their changes. The computer must additionally store in non-volatile memory an archive of measured data, an event log, including emergency situations, and be able to check the settings using standard tools or external devices and remote access tools.

5) The settings are entered into the settings card, which is drawn up in the passport of the measuring instrument or as a separate document in the project of the metering unit. Any changes to the settings must be recorded in the event log of the measuring instrument.

6) In the case of using automated measuring metering systems, instead of calculators (heat meters), data collection and transmission controllers (calculation converters), which are measuring instruments of approved types, can be used. In this case, the measured parameters are calculated by the automated system itself.

Also, the project describes the principles of design, placement and commissioning of commercial heat metering devices.

Compared to the current Decree of the Government of the Russian Federation No. 1034 of November 18, 2013, in this draft resolution:

the sequence of sections of the Rules has been changed to ensure consistency in the organization of commercial accounting of thermal energy and coolant;

the provision defining its scope of application has been changed (clause 1 of the Rules);

additions and clarifications have been made to a number of concepts used (clause 3 of the Rules);

the conditions for the use of metering devices during the 3-year transition period have been specified (in accordance with paragraphs 6 and 7 of the Rules);

clauses providing for the use of cold water temperature at the source of thermal energy to adjust the amount of thermal energy received by consumers have been excluded, since this contradicts the provisions of the current Pricing Fundamentals in the field of heat supply, approved by Decree of the Government of the Russian Federation of October 22, 2012 No. 1075 and distorts the true value of the quantity consumed thermal energy. The temperature of cold water at the source should be measured and taken into account exclusively when determining the amount of own costs and when setting the tariff for supplied thermal energy and coolant.

In accordance with the Federal Law "On Heat Supply", the Government of the Russian Federation decides:

1. Approve the attached Rules for commercial metering of thermal energy and coolant.

2. Federal executive authorities must bring their regulatory legal acts into compliance with this resolution within 3 months.

3. The Ministry of Construction and Housing and Communal Services of the Russian Federation must approve within 2 weeks the methodology for commercial accounting of thermal energy and coolant.
