Integration of energy markets within the Energy Community and with the EU market builds on accurate information on competition, market concentration, monopolies, price structure and price levels, applicable fees and charges, subsidies and other elements relevant for a level playing field for all the participants. The status and changes of supply and demand, fuel mix and emissions, stocks levels, import dependency, consumption patterns, short term information and long term trends and projection are of particular interest in this context. At the same time, the commitments of the Energy Community in the areas of energy efficiency, renewable energy sources and oil stocks require effective monitoring and reporting based on sound and reliable data.


The data collection serving this purpose is internationally harmonized and based on cooperation between EUROSTAT, the International Energy Agency (IEA) and the UN-Statistics Division (UN SD). The Energy Community follows this course. The unified EUROSTAT/IEA/UNECE approach enables the collection of annual statistics using a set of five joint questionnaires (oil, coal, gas, electricity and renewable energy) based on harmonised definitions, units and methodology. For energy market data, the EU requirements for transparency of gas and electricity prices and respective EUROSTAT methodology, were found as the best approach for the purpose of implementing the Treaty.


When implementing the rules on energy statistics, the responsible institutions are to resort to manuals, guidelines and reference textbooks developed by or in cooperation with the IEA, EUROSTAT, UN SD. These explain the applicable methodologies and provide clarifications and best practice examples.
