Common system for the production of energy statistics

KEY POINTS

Terminology

Technical terms are defined and clarified in the regulation’s Annex A.

Data sources

EU countries are required to compile statistics concerning energy products and their aggregates from the following sources:

• specific surveys addressed to the primary³ and transformed⁴ energy producers and traders, distributors and transporters, importers and exporters of energy products;
• other surveys addressed to final energy users in the sectors of manufacturing industry, transport, and other sectors, including households;
• other estimation procedures or other sources, including administrative sources, such as regulators of the electricity and gas markets.

Transmission and dissemination of data

Reporting countries must transmit national statistics to the European Commission (Eurostat) as laid down in the regulation’s annexes:

• annually for energy statistics in Annex B;
• monthly for energy statistics in Annex C (data must be transmitted to Eurostat within 55 days following the reported month);
• short-term monthly for the energy statistics in Annex D (data must be transmitted to Eurostat within one calendar month of the month reported).

The transmission arrangements, including the applicable time limits, and any exceptions and exemptions are set out in the annexes. Over time, these arrangements may be modified by the Commission.

Eurostat must disseminate annual statistics no later than 31 January of the second year after the reported period.

Quality assessment and reports

EU countries are responsible for the quality of the data they transmit to Eurostat. In particular, they must ensure that energy data they declare under this regulation matches data they declare with regard to the EU Monitoring Mechanism Regulation.

The Commission (Eurostat) assesses the quality of data from several perspectives including their relevance, punctuality, accessibility, clarity and comparability.

Every 5 years, EU countries must provide Eurostat with a report on the quality of the data transmitted, as well as on any changes in methodology that have been made.

Annual nuclear statistics

As of 2009, EU countries have been preparing statistics on the nuclear sector. The set of statistics collected concerns the civil use of nuclear energy.

Renewable energy and final energy consumption statistics

To ensure better quality and more comprehensive renewable energy and final energy consumption statistics, the Commission, with the EU countries, is reviewing and revising the methodologies used in their production. In particular, countries are required to transmit more disaggregated⁵ data for final energy consumption in households as from reference year 2015 and more detailed data on renewable energies as from reference year 2017.

Implementing legislation

The Commission is granted the power to adopt supplementary legislation designed to implement this regulation.

Committee

The Commission (Eurostat) is assisted and advised by the European Statistical System Committee, a committee composed of representatives from EU countries and chaired by the Commission.
