Owner and operator of the Nigg factory

Sumitomo Electric opened the UK's first high-voltage subsea cable factory at the Port of Nigg on Scotland's northeast coast on October 19. The £350 million plant, inside the Inverness and Cromarty Firth Green Freeport, will make 525-kilovolt cables that carry offshore wind power long distances with less energy loss than alternating current. Scotland Secretary Douglas Alexander said the UK had been the only G7 country without the capacity to make them.
