New rules for commercial accounting of thermal energy

In 2013, the Rules for the commercial accounting of thermal energy were approved (1304 Government Decree of November 18). From the moment the regulatory enactment came into force, the federal executive structures were obliged to bring their legal documents into compliance with it within three months. The Ministry of Housing and Public Utilities and Construction within two weeks was to establish a methodology for conducting commercial accounting. 3 years after the adoption of the above normative act, some amendments were made to it. Next, we consider the new Rules for the commercial accounting of thermal energy in 2016 .

General Provisions

New rules for the commercial accounting of thermal energy, heat carrier determine:

1. Instrument Requirements.
2. Characteristics to be measured. Indicators are used to ensure quality control of services.
3. The procedure for determining the volume of supplies.
4. Features of the distribution of heat energy and coolant losses in the absence of metering devices at the borders of adjacent heating networks.

Goals

New rules for commercial accounting of thermal energy are aimed at ensuring:

1. Settlements between service enterprises and consumers.
2. Control of operating modes of supply systems and consuming installations.
3. Supervision of the rational use of raw materials.
4. Documentation of equipment indicators (pressure, volume, mass, temperature).
   

Features of the technique

The 2016 rules for commercial metering of thermal energy require the use of special devices. They are installed at points located on the borders of the balance sheet. Another section may be provided for by the contract for the supply, supply or transfer of heat energy (coolant). Serving enterprises cannot require consumers to install other devices or additional devices not provided for by the regulatory enactment.

Rules for organizing commercial metering of thermal energy

To achieve the goals indicated above, the following are carried out:

1. Obtaining technical conditions.
2. Design and installation of accounting devices.
3. Unit commissioning.
4. Use of appliances. Into operation, among other things, includes regular taking of readings from devices.
5. Checking, repair, replacement of devices.
   

Explanations

The rules of commercial accounting of thermal energy require that the nodes be equipped in places as close as possible to the boundaries of the balance sheet. In this case, the real possibilities at the facility should be taken into account. The provision of technical conditions for the installation of devices, their commissioning, sealing, as well as participation in the commission for acceptance of nodes are made without charging consumers. At the sources, the devices are installed on each terminal of the network.

Device readings

The rules of commercial accounting of thermal energy establish the procedure for collecting information from devices. In this case, a list of mandatory testimonies is established. These include:

1. The amount of transported, received, supplied heat energy in the composition of hot water.
2. The number and duration of device malfunctions.
3. Other data provided by technical documents and displayed by devices.

The rules for commercial accounting of heat energy require the collection of this information to consumers or service enterprises, unless otherwise provided by an agreement between them.

The timing

The rules for the commercial accounting of thermal energy oblige consumers or service companies to provide the companies that carry out water disposal / water supply, taken on the 1st day, readings from the instruments no later than the 2nd day of the month that follows the settlement. Other terms may be established by law. Information about the current testimony is provided within two days (working hours) from the date of acceptance of the corresponding request. Information is sent by any available method, including by e-mail, which allows confirming its receipt.

Act of reconciliation

It is drawn up during the inspection in case of discrepancies between the actual readings and the data provided by the consumer or service company. The reconciliation report must be signed by the representative of the supply company or end user. In case of their disagreement with the content of the document, it is marked “Familiarized” and certified by painting. The objections of the network enterprise or consumer can be indicated in the act or sent in a separate letter to the supplying organization. In case of refusal to sign the document, a corresponding mark must be present in it. The reconciliation act acts as the basis for the recalculation of the volume of supply of coolant, heat from the date of signing.

Parallel devices

They can be used by a grid company or a consumer to provide control over the amount of heat supplied. In this case, the second side must be notified of the installation of such devices. The devices are located in areas that allow for commercial accounting. If differences in the readings of parallel and main devices are detected by more than the permissible measurement error for a period equal to at least one billing month, persons who installed the control equipment may require extraordinary verification from the other side.

Settlement order

Commercial accounting in this way is allowed with:

1. The lack of control points of the main devices.
2. Violation of the terms stipulated by the contract for the submission of information from devices owned by consumers.
3. Malfunctions of the main unit.

The calculation method is also applied in the case of an uncontracted supply of heat energy, coolant.

Determination of consumption

The amount of heat energy, coolant that were supplied by the source is expressed in the sum of the indicators for each pipeline (make-up, return and supply). The volume is determined by the supplying company in accordance with the readings for the billing period. In some cases, in order to establish the supply quantity, it is necessary to measure the temperature of the cold water at the source. In such situations, it is allowed to introduce the corresponding indicator into the calculator as a constant. At the same time, the consumption volume should be recalculated periodically taking into account the actual temperature. The introduction of a zero indicator t during the year is allowed.

Actual temperature

For a heat carrier, it is determined by a single supplying company in accordance with data on monthly average values ​​at a heat source. The relevant information is provided by their owners. Within the supply boundaries, the indicators of the actual average monthly t are the same for all users. The frequency of recounting is established by the contract. For hot water, the actual temperature is determined by the company operating the central heating section. To do this, cold water indicators are measured directly in front of the heaters. The frequency of recounting is also established by the contract.

Methodology

It allows you to:

1. Organization of commercial accounting in networks, at the source and coolant.
2. Determination of consumption. It includes the amount of heat energy, coolant, released, received, as well as spent in the absence of metering.
3. Determination of volume with unconditional consumption.
4. Distribution of heat loss.

During the operation of devices for an incomplete period, a flow adjustment is necessary. In the absence of monitoring devices at the accounting points or during their operation for more than 15 days. determination of the amount of heat used for heating and ventilation is carried out by calculation, based on the recalculation of the base indicator of changes in t of outdoor air.
