National Grid's robotic inspection device GRAID can inspect the inside of live, high-pressure gas pipelines, up to 100 bar(g) and provide reliable condition data on our critical assets. This technological leap will allow NGGT to cut asset maintenance costs by eliminating unnecessary excavations and providing data to allow asset life extension. It will also generate potential carbon savings of more than 2,000 tonnes annually, equivalent to the emissions from almost 500 UK households. It is a critical benefit as we move towards a low-carbon economy. In addition, National Grid are open and willing to discuss collaboration projects with any interested TSOs.
