40% gap


Transmission technologyAC vs. DC


HVDC projects and technologyHVDC vs. HVAC

But cost is not everything:

AC cable > 50 km needs reactive power compensation, which is technically absurd as far as offshore is concerned

Environmental impact: DC cable has no electrical field and has lower losses, which leads to a lower thermal impact
