How offshore wind turbines are connected to the grid
- Published 11 February 2025; updated 30 September 2026; estimated reading time 3 minutes. The introduction cites Europe’s aim to reach at least 60 GW of offshore wind by 2030, noting the need for grid infrastructure; this is a page-stated target/forecast.
- Inter-array cables connect turbines to an offshore substation, which aggregates and steps up AC voltage to reduce transmission losses. Subsea export cables carry electricity to onshore grid connections. For longer distances, HVDC converts power to direct current for more efficient underwater transmission. Shared or “meshed” offshore grids could reduce duplicated links, costs and operational vulnerability.
- Grid connection infrastructure includes subsea cables, offshore substations and onshore converter stations. Variable wind output must be synchronised with grid conditions. Digital monitoring can track voltage, frequency and demand to support reliable operation.
- International connections allow offshore farms to supply more than one country. The North Sea Link between the UK and Norway is cited as an example; hybrid interconnectors combine wind-farm export with cross-border transmission. The article says Norway’s Ocean Grid Project is exploring an offshore grid and links to its subprojects.
- Harsh sea conditions, installation cost and environmental impacts remain challenges. Floating and subsea substations can extend connections into deeper waters and tolerate severe conditions. The page also notes that surplus offshore wind could power green hydrogen production, potentially providing storage and easing grid pressure.
