>> Commodity balance: The purpose of commodity balance is to show the sources
of supply and various uses of particular energy product with reference to national
territory of the compiling country. The balance is compiled for any energy
commodity provided that the commodity remains homogeneous at each point in
>> International Recommendations on Energy Statistics (IRES) recommends that the
format of energy balance and all applicable concepts are consistently used in the
compilation of a commodity balance to ensure data consistency. The major sources
for commercial energy in India are coal, oil products, natural gas and electricity.
Non-energy producing sectors derive energy from the resources available in
primary form such as coal, crude oil, natural gas, hydro-power and nuclear power.
Some of the energy resources are converted into other (final) energy products that
are used for purposes other than energy generation.
>> Coal is also used as a final product or intermediate for power generation.
Similarly, natural gas is also used directly or as an intermediate in power
generation. Many petroleum products, such as HSDO, Naphtha etc. are used as a
final product by the non-energy producing sectors and also used for power
generation.This indicates that the same energy source can be used in various forms
at various stages of consumption. This creates a possibility of over-estimation or
under-estimation of energy consumption in totality as well as for different sources.
>> Energy Balance: An energy balance is a framework to complete data on all
energy products entering, existing and used within a given country during a
reference periods (e.g. a year). It expresses all data in common energy units, which
makes it possible to define a “total” product.
