Investigation into DC arrays as a means of connecting offshore wind farms

The Offshore Wind Accelerator have published an executive summary of a study investigating the opportunities and technological barriers towards implementing DC arrays in offshore wind farms. 

DC array report cover 2021


The use of medium voltage DC (MVDC) array cables rather than conventional 66kV or 33kV AC array cables to connect wind turbines to offshore substations, has been a subject of ongoing research by academic and industry bodies looking at cost reduction opportunities for offshore renewables for many years. 

About the report

The Offshore Wind Accelerator (OWA) have undertaken a number of studies to track the potential opportunities of the technology over time. This executive summary provides an overview of the most recent work highlighting the need for roadmaps to lay out the necessary steps to develop both commercial and technical capability to construct an offshore wind farm implementing DC arrays.

Based on the latest review, DC array technology still requires significant development before being used in an operational wind farm and utilisation could be over 10 years away.
