Robot trial takes SSEN networks innovation into the fast lane with Williams

06 Aug 2018

- SSEN to team up with Williams Advanced Engineering, part of the Williams Group, to trial the use of robots for high-voltage power line inspections.
- The semi-autonomous robot will travel along live power lines, taking crucial asset data to inform SSEN’s replacement and maintenance programme.
- A UK first, the results of the trial will be shared across industry.


Scottish and Southern Electricity Networks (SSEN) has entered into a partnership with Williams Advanced Engineering to design a functional specification for the first live overhead line inspection robot to be used on SSEN’s high voltage electricity networks

Funded by Ofgem’s Network Innovation Allowance, the LISAS (Line Inspection by Semi-Autonomous Systems) project will be the first time a highly autonomous robot will be used to inspect electricity networks in the United Kingdom.  The project aims to safely trial a robot system capable of making its own decisions without human control. It will navigate its own route as it moves from overhead line to overhead line, seamlessly navigating from steel tower to steel tower, as it captures critical asset data to inform reinforcement and maintenance requirements.

The deployment of robotics to carry out maintenance inspections on SSEN’s overhead lines will enable SSEN’s teams to carry out this essential work safely whilst the power remains live, helping deliver greater efficiencies and improved network reliability without the need for network outages, while keeping personnel safe.

Stewart Reid, Head of Distribution System Operator (DSO) and Innovation at SSEN, said:

“The use of robotics to help us inspect and maintain our network has the potential to provide enormous benefits to our customers and our people, from improvements in safety and network reliability, to reduced costs for our customers. Through Ofgem’s innovation funding we have the opportunity to trial this innovative technology on our network, sharing the lessons with our peers across the sector.

“Robotics are already changing the world around us and I am very excited to see this agreement in place with Williams Advanced Engineering. Dedicated to developing the most cutting-edge engineering projects, their team will bring significant technical expertise and knowledge to the project. Our partnership with them represents the extent to which networks companies such as SSEN are embracing new innovation and are adapting to a changing role in the industry.”

This innovative technology will minimise potential disruption to SSEN’s customers and provide up-to-date asset and safety data, along with photographs and video footage.  This data will help inform SSEN’s ongoing maintenance and replacement programme, ensuring SSEN continues to provide a safe and reliable supply of electricity to its 3.8 million customers in its north of Scotland and central southern England networks.

The LISAS project calls upon the engineering expertise of Williams Advanced Engineering through a partnership to develop the initial functional specification for the robotic device. A household name, famous for four decades of success in the ultra-competitive environment of Formula One, Williams Advanced Engineering brings world class technical innovation, engineering, testing and manufacturing expertise from which SSEN and the wider energy industry can learn.

Once developed, the specification will be released through a market tender to design and build the first autonomous robot to be used on this scale in the industry.  SSEN will trial the technology at various sites across its networks and will share the findings of the project with the wider energy industry, with this collaboration key to help inform new and innovative ways to manage the electricity networks of the future.

Iain Wight, Business Development Director at Williams Advanced Engineering, said:

“This is an exciting project for Williams Advanced Engineering.  The capabilities that we have are applicable across industry and our team is delighted to be able to apply them to the energy sector with SSEN.  As demand increases for more and more reliable power, not least to power electric vehicles where we are helping lead the way to a more sustainable future, it is essential that we take every step to secure supply and costs.  Our work with SSEN is another significant step towards delivering that for people and for future sustainable mobility.”
