The dataset contains information on the location of individual turbines in place or planned location for offshore wind farms in the Baltic Sea area as reported by the Contracting Parties for the period 2016-2021. The data was made available by HELCOM Contracting Parties in response to a data call. The data was reported by Denmark, Finland and Germany. The activity was declared as not relevant in Estonia and Latvia. The use of HOLAS 2 data was requested by Sweden.

The dataset contains the location of fossil fuel energy production facilities derived from the European Pollutant Release and Transfer Register (E-PRTR). E-PRTR cover all HELCOM Contracting Parties except Russia. Attribute specification and units: See E-PRTR code lists at https://www.eionet.europa.eu/schemas/eprtr/listOfValues In the HELCOM data review process, some facility locations appeared to be spatially slightly misplaced, adding up to uncertainty of data products derived from this dataset.

This dataset contains points data of hydropower dams and dams downloaded from OpenStreetMap.
