Chapter 4 – Data sources and data
collection
1) Practical guidance for a country to identify the
relevant and appropriate data sources for the
different data items of chapter 6 of IRES
 direct surveys (sample/census)
For example,
Production data –  Secondary sources (energy
agencies/ministries)
 Administrative data
Imports/exports –
 Direct surveys
 Secondary data (custom)
Consumption data
 direct surveys on the consumers
(e.g. households surveys)
 Surveys on the suppliers
 Administrative data
2) Guidance on the data compilation (editing,
imputation, estimation of missing data, etc.)
3) Guidance on the adjustments needed for the
compilation of the energy accounts
How to present the information?
By Section of SIEC (e.g. Coal, natural gas, Oil,
electricity and heat, etc.)?
For each SIEC section, a physical description of
the main processes of the products would be
presented and the relevant data sources for
types of data items (production/transformation,
trade, stocks, bunkers, consumption) could be
discussed.
By transactions?
E.g. production, trade, stocks bunkers
Example in the UN manual F 56
 Electricity
A. Production/generation
B. Primary generation of electricity
C. Secondary generation of electricity
D. Exports and imports of electricity
C. Availability and supply of electricity
D. Losses in transmission and distribution
E. Consumption of electricity by end-users
F. Preparatory work for the collection of regular
electricity statistics
Similar for Coal, Oil, Natural gas, etc.
 We should not forget also the other data
items in chapter 6 of IRES:
 Infrastructure (e.g., capacity)
 Monetary data items (e.g., prices, taxes,
subsidies, output, etc.)
 Energy resources (e.g., opening and closing
stocks)
When these data items are collected as part of
other statistical domain, we could make
reference the relevant guidelines
