Under the contract, Jacobs will support EDF Energy’s maintenance and life extension programs to 15 nuclear reactors and technical centers in East Kilbride and Gloucester.

The facilities covered under the contract include Dungeness, Hartlepool, Heysham 1 and 2, Hinkley Point, Hunterston, Sizewell and Torness power stations, which generate around 8.8 million kilowatts.

The contract is valid for five years, and has two optional two-year extensions.

Jacobs Group vice-president Bob Duff said: "We look forward to contributing significant expertise, local knowledge and global resource to help deliver safe, robust solutions across these important assets."

Said to be a major producer of low-carbon electricity, EDF Energy produces around one-fifth of the UK’s electricity needs.

Jacobs provides various services to EDF’s projects in the UK, including technical and engineering services for the company’s UK Nuclear New Build program and environmental services for the 2000MW Cottam and West Burton coal-fired stations.
