Scottish and Southern Electricity Networks Transmission (SSEN) and National Grid Electricity Transmission (NGET) have reached another significant milestone in the development of a new subsea electricity superhighway.

NGET currently use batteries alongside diesel generators to provide backup power to a substation for key activities such as cooling fans, pumps, and lighting, enabling it to continue to perform its crucial role in the electricity transmission system.

National Grid has been granted strategic innovation funding of £1.5m by Ofgem, the energy regulator, for 13 innovation projects that will accelerate Great Britain’s progress towards delivering a net zero energy network at the lowest cost to consumers.
