Production line Basic Energy Statistics (BES)

• Data collection within individual
  actors/companies
• National Questionnaires to transport information
  from companies to national statistical office
• Data processing and dissemination by national
  statistical office
• (Joint Annual) Questionnaires to transport
  national data to international organisations
• Data processing and dissemination by
  international organisations

Role and nature of concepts energy balances in
BES (1)

• basic principle balance concept what becomes
  available what is consumed(supply
  side) (demand side)
• based on natural relationship between energy
  variables
• defined set of definitions and classifications
• both energy commodity balances (in natural
  units) and energy balance (in energy units)

5
Role and nature of concepts energy balances in
BES(2)

• In all stages of the production line (most)
  basic energy information is presented/processed
  in the balance format - national
  questionnaires - national publications
  - international questionnaires (Joint Annual
  Questionnaires) - international
  publications (IEA, Eurostat, UN)
• The same definition set used for the entire
  production line national, international (Energy
  Statistics Manual) (As much as possible, room
  for improvements, forum ESWG, role for the Oslo
  group)

Role and nature of concepts energy balances in
BES(3)

• Why using balances?
• To collect and transport energy information in a
  transparent, structured, consistent and efficient
  way
• To check data on completeness and correctnessin
  all stages of the production line
• To publish energy information in a transparent,
  structured and consistent way. The chosen set
  definitions classifications makes it possible
  that the BES output can be is used by all kinds
  of users (national and international) energy
  saving/efficiency policy, energy supply
  (security) policy), environmental policy (Kyoto,
  IPCC)

11
Energy accounts SNA and relation to BES

• definitions based on macro-economic principles
  SNA well defined definitions and
  classifications
• supply and use tables of energy products
• similarity with BES balances balance concept
  supplyuse
• some of differences (a.o. residence versus
  border principle)
• but differences can be identified easily by
  having 2 well defined statistical systems SNA
  and BES

  Accounts

  information, estimates)department of National
  Accounts in close cooperation with department of

• Concluding remarks (1)
• The concept of energy/commodity balance is
  connected with all stages of the production line
  of Basic Energy Statistics BES (framework,
  coherent structure) from energy data in
  individual companies on up to international
  publications/output
• Provides a powerful tool to generate good
  quality energy information efficiently
• It is much more than just a possible alternative
  to publish energy data
• Output conform BES-definitions (energy balances,
  commodity balances) to be derived directly from
  BES inefficient and a roundabout way to do that
  via supply and use database conform SNA
  definitions

16

• Concluding remarks (2)
• Results BES can be used to make Energy Accounts
  
• Differences energy balances (BES concept) and
  energy accounts (SNA concept) easy to identify
  by having two well defined statistical systems
  BES and SNA
• Dutch experience shows that differences can be
  bridged in a regular statistical production
  process with some additional data collection and
  estimates (bridge tables)
• Dutch experience it is not necessary (and
  possible inefficient) to put all basic
  information in one database
• 2 recognisable statistical systems (different
  concepts, structuring frameworks, type of output,
  responsibility) have proven to be a practical way
  to operate (transparent, flexible, efficient)
• Role Oslo Group versus London Group along the
  lines of the 2 statistical systems (next figure)
