Methodological explanation for the news release:


Balance of Oil


Sources of data collection

Sources of data collection for the annual report on Oil are: Monthly surveys on energy, Ene.6, Ene.7, Ene.10, Ene.12, Ene.13, Annual surveys on energy, Ene.56, Ene.57, Ene.60, Ene.62, Ene.63, Annual survey on forestry, Annual survey on agriculture, Statistical survey on external trade, Estimation of consumption in households by types of energy commodities.

Data scope

In the process of collecting data from the reporting units the method of full coverage is used (for business entities that perform production), as well as the sample method (for business entities that are consumers of Oil).

Definitions

For defining the categories in the balance scheme the Annual Questionnaire for Oil, 2009 of Eurostat, ECE/UN and IEA/OECD is used.

Motor Spirit = Unleaded Motor Gasoline + Leaded Motor Gasoline + Aviation Gasoline

Kerosenes, Jet Fuels = Gasoline Type Jet Fuel + Kerosene Type Jet Fuel + Other Kerosene

Gas/Diesel Oil = Transport Diesel + Heating and Other Gasoil

Other Petroleum Products = Refinery Gas + White and industrial Spirit + Lubricants + Bitumen + Paraffin Waxes + Other Petroleum Products

Import/Export represents the quantity that entered/left the national territory.

Transformation input includes Petroleum Products consumed for conversion into another energy form (Heat and Electricity).

Public thermal power stations are plants for production of Electricity only.

Autoproducer thermal power stations are plants for combined production of Electricity and Heat.

CHP plants are combined heat and power plants, which produce both heat and electricity intended for sale.

Main activity producer heat plants and Autoproducer heat plants are plants for production of Heat (for consumption of public and other sectors).

Exchanges and transfers, returns represents transfer of produced Petroleum Products for further production.

Available for final consumption are Petroleum Products available to final consumers.

Statistical difference = Available for final consumption - Final non-energy consumption - Final energy consumption

Available Petroleum Products = Gross inland consumption + Transformation output + Exchanges and transfers, returns

Calculation method

For calculating the separate Balances of Oil and Petroleum Products (total, by months) the methodology ‘’Energy Statistics Methodology Eurostat F4, 1998’’ is used.

Classifications

In the distribution of the final consumption of Petroleum Products the National Classification of Activities (Official Gazette of the Republic of Macedonia No. 09/2006) is used.
