The extension, includes maintenance and upgrade of UK’s electricity transmission network in an agreement worth up to GBP750 million.

Balfour Beatty will be responsible for the design, programme management, construction and technical support for National Grid’s electricity network.

The scope of work involves the ongoing maintenance and restoration of overhead transmission lines, as well as designing and delivering National Grid’s upgrade plans across the network.

Furthermore, the project demonstrates the Group’s infrastructure capabilities, particularly in areas where clients face large and complex challenges.

Balfour Beatty and National Grid formed the Electricity Alliance East partnership five years ago to secure the long-term stability of much of the UK network.
