National Grid Electricity Transmission

National Grid Electricity Transmission (NGET) owns and maintains the high-voltage electricity transmission network in England and Wales. That includes 7,212 kilometres of overhead line, about 2,239 kilometres of underground cable and 346 substations. We move electricity from where it’s generated, down the ‘motorway’ of the electricity system, to our direct customers and to the distribution
companies who deliver that power to homes and businesses.


We play a vital role in connecting millions of people to the energy they use, safely, reliably and efficiently. Through transformational engineering, we are helping our country to achieve its green targets, by ensuring our network gives fair access to cleaner sources of energy.

The transition to a low-carbon economy is one of the defining issues of the 21st century,and we can’t make a bigger difference in today’s, or tomorrow’s, world than to create a road to net zero.
