The three-year framework agreement has an option to extend for a further two and is worth £3m a year.
The deal sits alongside Interserve’s two other on-going frameworks with Northern Powergrid to undertake supply and installation of EHV cables as well as EHV wood-pole overhead lines.
Guy Bruce, Interserve Managing Director – Industrial said: “The project requires considerable engineering and technical skills, already proven with Northern Powergrid as well as our wider client base.
“We have worked in this field for over 90 years and are working alongside our client to ensure that Yorkshire and the North-east have a well-founded electrical infrastructure in place for the future.”
