Electricity or Energy Cables are essentially submarine power cables. Such a cable is a major transmission cable for carrying electric power below the surface of the water. The purpose of submarine power cables is the transport of electric current at high voltage. The electric core is a concentric assembly of inner conductor, electric insulation and protective layers. Modern three-core cables (e.g. for the connection of offshore wind turbines) often carry optical fibers for data transmission or temperature measurement, in addition to the electrical conductors.
Electricity Cables is a static data layer. They are point-by-point lines that you can draw in, edit or remove when making a plan.
Electricity Cables create the following pressures on the ecosystem:
Electricity Cables disallow all three fishing fleets (bottom trawl, drift and fixed nets, industrial and pelagic trawl).

HELCOM HOLAS II Dataset: Cables (2018)
Cables
"The dataset was created in order to update the information regarding underwater cables in the Baltic Sea Region for the HELCOM Assessments. Data was collected by the HELCOM Secretariat during 2015 and 2016. The dataset contains information on submarine cables in the Baltic Sea. The dataset is based on available public sources on cables and due to variety of data sources (national and international), should be taken as general data based on best available public data with variable resolution over the different region in the Baltic. For Danish areas, the data represents constructions on Danish territorial waters, authorized facilities and activities from 2015. Depending on area, more accurate spatial data might exist, but data is unavailable for public use. National data submissions from Latvia and Russia were not available.
For 2018 version of dataset, cables that have only approximate location were removed from the dataset, as the spatial accuracy of these objects is not sufficient for the scale of the index.

Based on the "Cables" and the "Wind farms" layers a model for the renewable energy scenario in 2016 was created. Only the cables that would be needed to bring the energy from the wind farms to shore are taken into account in the plafform as energy cables. Some geometries might have been simplified for optimization of the platform's performance.
