ScottishPower, through its parent company Iberdrola, has secured £600 million (around €693 million) in financing from the National Wealth Fund to support the development of the fourth out of five subsea electricity superhighways between Scotland and England.

The 2 GW Eastern Green Link 4 (EGL4) high-voltage direct current (HVDC) subsea power link will run between Fife and Norfolk, with its 530-kilometer cable to be able to transmit enough electricity to power the equivalent of 1.5 million UK homes.
