Introduction: To assist with delivering our capital plan we are seeking to gain an understanding of alternative methods of inspection and maintenance of our overhead line assets. With system access being a major concern we wish to gain an insight into possible technologies that can be deployed and operated on live circuits.

We have already looked tentatively into this area, seeking out the world leaders in this technology, which has led us to forming an association with IREQ, the research institute of Hydro Quebec, Canada. They have developed and deployed an overhead line inspection and maintenance Robot known as Linescout. This project will develop the technology with respect to the GB network.

Objectives: Investigate the possible solutions available for the deployment of robotic technology on overhead lines to assist with asset condition and maintenance activities. To trial world leading technology on our system to gain understanding of compatibility and potential impact.
