The Joint Research Centre's Integrated Database of the European Energy System (JRC‑IDEES) consolidates a rich set of information allowing for highly granular analyses of the dynamics of the European energy system, so as to better understand the past and create a robust basis for future policy assessments.
JRC‑IDEES provides a consistent set of disaggregated energy-economy-emissions data for each Member State of the European Union, covering all sectors of the energy system for the 2000-2021 period: industry, buildings, transport, and power generation. This data complies with Eurostat energy balances while providing a plausible decomposition of energy consumption into specific processes and end uses.
In each sector, JRC‑IDEES uses a vintage-specific approach to define the energy-using equipment in operation and identify different energy system drivers accordingly. It then provides insights on their role by sector, while accounting for structural differences across countries.
As such, JRC‑IDEES has several key applications for energy-related research and policy analysis, such as the parameterization of energy models and the assessment of past and prospective policies.
JRC‑IDEES, first released in 2018, was initially designed to serve as the main data input for the POTEnCIA model. The latest JRC‑IDEES-2021 update introduces a number of methodological refinements and extends the data coverage until 2021.
Data access
JRC‑IDEES-2021 is available through the JRC Data Catalogue. The reporting structure and decomposition methodology are documented in a separate technical report.
