JRC Hydro-power plants database

map of hydro-power plants

The development of this dataset started as an output of the Energy work package of the Water-Energy-Food-Ecosystems (WEFE) Nexus project at the European Commission's Joint Research Centre (JRC). This dataset has been created for power system modelling purposes and it is based on publicly available sources. This dataset tries to collect some basic information on all the European hydro-power plants. Other related datasets are available in the JRC Data Catalogue.

The dataset contains the following variables (documented in the data package JSON):

  • id of the plant
  • name of the power plants
  • installed capacity (and pumping capacity when available)
  • country
  • coordinates
  • typology of the power plant (run-of-river, reservoir based or pumped-storage)
  • nominal head or height of the dam
  • size of the usable reservoir in million of cubic meters
  • maximum storage capacity in MWh
  • link with the GEO, PyPSA-EUR and WRI Global Power Plants databases
  • annual average/expected generation in GWh

The storage capacity is reported only when directly available from the source, thus is not estimated or derived from the other variables.

This dataset is released under CC-BY-4.0 license. This dataset is an open project and it is not an official product of the European Commission.

The database has been built collecting the information from several other sources and then cross-checking and comparing in case of inconsistencies. The list of the used sources is here:
