We’re supporting National Grid in its journey to build a world-leading, future-ready electricity transmission system providing specialist support in delivering essential improvements and upgrades to their national critical substation infrastructure. The five-year framework includes construction design management and site management with principal contractor responsibilities.

Over the RIIO-T1 regulatory period, we upgraded and refurbished 74 transmission substations. Our continued role as a strategic supplier on RIIO-T2 is a testament to our ongoing development and investment in our people, technologies, and systems to support National Grid’s journey in building a world-leading future energy system.
