Offshore Transmission Export Cables Database

Export cables transfer power from offshore wind farms to connect to an onshore grid network typically via intermediate AC substations or DC converters. In some instances, export cables can connect to an offshore grid system, as seen in Germany, or alternative end-use such as oil and gas platforms or industrial facility. AC technology has been the most preferred technology in export cables in the past; but now DC technology has also started to be used, partly due to increased distance from shore. In total, ~ 13,760 km export cable has been installed, which includes, ~2,299 km MVAC cable, ~11,049 km HVAC cable and ~412 km HVDC cable. The number of export cables may vary between 1 to 13, depending on offshore wind farm size and design.
