JSM Group has been appointed by Statera Energy to carry out 400kV cable installation works for a new Battery Energy Storage System (BESS) facility at Wharfside Business Park in Greater Manchester, marking another step forward for the specialist infrastructure engineer in the UK’s energy transition.

The contract covers the installation of a duct route and a 400kV underground cable circuit spanning approximately 1km in a single circuit configuration — a critical piece of the new energy storage infrastructure serving the region.

JSM Group’s Power team will lead stakeholder engagement throughout the project, working closely with National Grid, local authorities and third-party landowners to keep delivery on track. Before excavation begins, the company’s in-house civil engineering teams will carry out preparatory works, including sheet piling along the site’s steep embankment to form a retaining wall. This will guard against ground instability and provide a safe working platform for the duration of the project.

Reflecting the momentum behind the UK’s energy transition

“We are delighted to have been selected by Statera Energy to deliver this significant high-voltage project. The installation of 400kV infrastructure for a battery energy storage facility reflects both the growing momentum behind the UK’s energy transition and the depth of capability that JSM Group brings to complex power projects. Our team has the technical expertise and operational experience to manage every aspect of this work safely and efficiently, from stakeholder engagement through to the final cable installation. We look forward to working closely with Statera Energy and all parties to deliver this project to the highest standards.”

The project builds on JSM Group’s growing track record in high-voltage power infrastructure and reinforces its position as a trusted delivery partner for complex, technically demanding energy projects across the UK.

The electrical supply will run from Belvedere and terminate at the Littlebrook substation in Dartford.

This project will be one of the largest and most efficient Energy from Waster (EfW) facilities in the UK, employing 140 personnel from the area, processing 650,000 tonnes of non-recyclable waste and generating enough electricity to power 176,000 homes each year. The facility will utilise well-established moving grate technology. This technology has been successfully deployed across numerous operational EfW facilities in the UK.

Over 3 million tonnes of London’s waste must either be landfilled or sent overseas, and this project will provide vital capacity to help address this. It will also help to achieve the goals set out in the London Plan which aim for 100% of London’s waste to be processed within its boundaries by 2026.

We apologies for the disruption this has caused and are working hard with key stakeholders including London Borough of Bexley to ensure minimum disruption to the public. We are working extended hours 7 days a week to ensure they are completed as soon as possible and will be providing a live website that shows the works programme and the live closures.

As the works progress, we will provide weekly updates via the website to assess suitable changes showing where the works are and changes to the traffic network.
