The refurbishment of Sellafield site's electricity system

A critical project to upgrade Sellafield鈥檚 electrical power network has hit an important milestone.

The Electrical Distribution Network Upgrade Project, known as EDNUP, 聽is working to refurbish the Sellafield site鈥檚 electricity system.

Teams working on the project installed 33 concrete base slabs last year, achieving a key target.

Laying slabs on a site as complex and congested as Sellafield is no easy job.

Each one relies on excavation work in areas with uncertain ground conditions. The team can encounter issues like unexpected pipes, cables, and even asbestos from the site鈥檚 earliest days.

When complete, EDNUP will play a key role in the refurbishment of Sellafield鈥檚 entire electricity network.

That will improve site resilience, bolster emergency power generation, and ensure new buildings can be connected to the power supply.

Jenifer Carruthers, Sellafield Ltd鈥檚 head of site management project office, said:

This is a huge success for a project delivering essential asset care, creating resilience, and developing new standby power capability across the electrical network.

Everyone on the team can be proud of the part they continue to play in delivering this mission critical project.

Teams delivering the work include the Infrastructure Strategic Alliance, a joint venture between Sellafield Ltd, Morgan Sindall, and ARUP (MSA).

Colleagues from Sellafield Ltd鈥檚 infrastructure and construction teams are also supporting the project.

In total, more than 500 interconnector bases are needed on the project. To date, 255 have been delivered.

They will support a staggering 750 kilometres of cabling. Enough to stretch from Sellafield to Land鈥檚 End, in Cornwall.
