Infrastructure giant Balfour Beatty has announced a multi-million deal for Hinkley Point C.
The contract will see the firm deliver the £214 million North and South 400kV overhead line project on behalf of National Grid.
It will also employ over 150 workers.
The deal follows Balfour’s agreement to install the nuclear power station’s electrical works package in a joint venture with NG Bailey in 2015, and the tunneling and marine works package in 2017.
Delivery of the project will see Balfour Beatty design, supply, install, test and commission almost 30 miles of cable works.
Mark Bullock, Balfour Beatty’s chief executive for rail and utilities, said: “Our extensive knowledge and unique capability in delivering major complex Overhead Line schemes, makes us ideally positioned to play a key role in helping to deliver the first nuclear power station to be built in the UK for more than 20 years.
The majority of renewable energy is used as a source of electricity.
“We look forward to working with National Grid to successfully and safely deliver low-carbon electricity for around six million homes across the UK.”
Work is due to begin this month and continue until 2025.
