Foreword
This Standard was drafted as per the rules specified in GB/T 1.1-2009.
This Standard replaced GB/T 2589-2008 General Principles for Calculation of the
Comprehensive Energy Consumption. Compared with GB/T 2589-2008, the major
technical changes of this Standard are as follows.
--- Modify the definitions such as "energy calorific value", "energy source equivalent
value", "comprehensive energy consumption", "comprehensive energy
consumption for unit output value" and "comprehensive energy consumption for
unit output of product" (see 3.2, 3.3, 3.5~3.8 of this Edition; 3.2, 3.3, 3.5~3.8 of
2008 Edition); and add the definition of “standard coal coefficient” (see 3.9);
--- Add "boundary division" (see Clause 5 of this Edition);
--- Modify "energy source type and scope for calculation of comprehensive energy
consumption", they are respectively included in "calculation principles" and
"calculation range" (see Clauses 4 and 6 of this Edition; Clause 4 of 2008 Edition);
--- Modify "principles of conversion of standard coal for various energy sources" into
"requirements for conversion to standard coal" (see Clause 8 of this Edition;
Clause 6 of 2008 Edition);
--- Modify Appendixes A and B (see Appendixes A and B of this Edition; Appendixes
A and B of 2008 Edition).
This Standard was proposed by and under the jurisdiction of National Technical
Committee for Standardization of Energy Fundamentals and Management (SAC/TC
20).

General Rules for Calculation of the Comprehensive
Energy Consumption
1 Scope
This Standard specifies the calculation principles, boundary division, calculation range,
calculation method, and requirements for conversion to standard coal of the
comprehensive energy consumption.
This Standard is applicable to the calculation of energy consumption indicators for
energy consumption unit (including secondary energy consumption unit or their
components).
2 Normative References
The following documents are essential to the application of this document. For the
dated documents, only the versions with the dates indicated are applicable to this
document; for the undated documents, only the latest version (including all the
amendments) is applicable to this document.
GB/T 3102.4 Quantities and Units - Heat
GB/T 3484 The General Principles for Energy Balance of Industrial Enterprise
GB 17167 General Principle for Equipping and Managing of the Measuring
Instrument of Energy in Organization of Energy Using
GB/T 28749 The Method of Drawing Energy Balance Network Diagram for
Enterprises
3 Terms and Definitions
For the purpose of this document, the following terms and definitions apply.
3.1 Energy-consumed medium
The working substance that is consumed in the production process, but not used as a
raw material; nor it enters the product; it needs to directly consume energy during
production or preparation.
3.2 Energy calorific value
The equivalent amount when different forms of energy are converted to each other.
According to the legal measurement unit of energy in Joule, the conversion coefficients
of different forms of energy such as thermal energy, electrical energy, and mechanical
energy are all 1.
3.4 Energy consumption unit
The energy consumption unit that has definite boundary.
3.5 Comprehensive energy consumption
During the statistical reporting period, the actual amounts of various energies that are
consumed in the production of a certain product or the provision of a certain service; it
is the sum of the converted amounts according to the prescribed calculation methods
and units.
3.6 Comprehensive energy consumption for unit output value
During the statistical reporting period, the ratio of comprehensive energy consumption
to the total output value or added value (comparable price) of energy consumption unit.
NOTE. The unit of comprehensive energy consumption for unit output value is usually. in kgce/
ten thousand yuan, and tce/ ten thousand yuan, etc.
3.7 Comprehensive energy consumption for unit output of product
During the statistical reporting period, the ratio of comprehensive energy consumption
to the output of qualified product (operation capacity, workload, service capacity).
4 Calculation Principles
4.1 Compliance. The types of energy included in the calculation of comprehensive
energy consumption shall meet the requirements of national energy statistics.
4.2 Completeness. The calculation of comprehensive energy consumption shall
include all energy and energy-consuming medium actually consumed in the production
process; and shall not be omitted or recalculated.
5 Boundary Division
5.1 Appropriate calculation boundaries shall be delineated in accordance with relevant
laws, regulations and standards. For the purpose and actual situation for the
calculation of comprehensive energy consumption, the boundary may be the whole of
the energy consumption unit, or the secondary energy consumption unit, or it may be
a component of it.
5.2 Boundary division may take different forms, choose one of them to determine the
boundary of the calculation of comprehensive energy consumption. Once the
boundary is determined, it shall not be changed in the process of calculation of
comprehensive energy consumption.
5.4 If the energy-consuming units are located in two or more secondary energy
consumption units or their components in different geographical locations, then
multiple boundaries may be delineated as needed to facilitate the calculation of
comprehensive energy consumption by energy consumption units.
6 Calculation Range
6.1 The calculation range of comprehensive energy consumption includes the actual
consumption of various energy such as primary energy and secondary energy;
includes the energy used as raw materials. The actual consumption of various energy
may be calculated in accordance with GB/T 3484, GB/T 28749, GB/T 28751, etc.
6.2 The energy consumed by the energy-consumed medium shall be included in the
calculation of comprehensive energy consumption. Energy-consumed medium mainly
include fresh water, softened water, compressed air, oxygen, and nitrogen, etc.
6.4 The raw data that can be used to calculate the comprehensive energy consumption
include the reading records of energy measuring instruments, the data records of the
online energy consumption monitoring system, the energy statistics reports, the
invoices, and the energy bills, etc. The equipment of energy measuring instruments
shall meet the requirements of GB 17167.
7 Calculation Methods
7.1 The comprehensive energy consumption is calculated according to Formula (1).
7.3 The comprehensive energy consumption for unit output of product is calculated
according to Formula (3).
7.4 Comparable comprehensive energy consumption for unit output of product is
suitable for comparison of product energy consumption within the same industry. The
calculation method may refer to relevant standard specifications and technical
documents.
8 Requirements for Conversion to Standard Coal
8.1 When calculating the comprehensive energy consumption, various energy sources
shall be converted into standard coal.
8.2 The actual fuel energy consumption shall be converted into standard coal quantity
based on the calculation basis of its received base low calorific value.
