Upcoming works at Hackney Substation and Millfields Park

Planned works are now taking place at Hackney Substation and within parts of Millfields Park as part of the North London Reinforcement Project.

These works are taking place from May and will help us carry out important maintenance and upgrades to the electricity network serving North London safely and reliably.

What to expect

Work is currently taking place at Hackney Substation as part of the reinforcement. This includes clearing vegetation within the substation site, conducting ground surveys, and installing temporary ground protection mats to help protect surfaces during the works.

Our work within the substation will take place from 8am to 5pm including some weekends.

Work in Millfields Park

We will soon be carrying out our overhead electricity lines within Millfields Park and we will be placing ground protection mats in some areas of the park. We expect to be finished with the work in Millfields Park by the end of August.
While we work on the overhead line, our working hours are 7:30am to 6pm, Monday to Friday. We also need to work every other weekend. Saturday working hours are 7:30am to 1pm and Sunday working hours are 7:30am to 3pm.

Hackney is a key location for the NLR project, with a large portion of works taking place within Millfields Park. These works are being delivered under permitted development rights and are integral to the overall delivery of the NLR programme.

Our work will primarily involve uprating the existing overhead line (OHL) between the Tottenham and Hackney substations, which will enhance the existing line's ability to carry more electrical load safely.

The site will also see four Supergrid Transformer (SGT) movements, as we will be removing the two SGTs currently onsite and replacing them with two new ones with greater capacity. This will enable the substation to operate at a higher voltage, enhancing network stability and future-proofing the infrastructure to accommodate growing energy needs.

To facilitate construction, we will need to undertake enabling works. Enabling works are preparatory activities such as vegetation clearance, fencing installation, temporary access tracks, and scaffolding construction. These steps are needed before the main substation upgrades and OHL improvements can begin.

Enabling works have already started in the area, however, wider works are still being scheduled, and we will communicate timings when the programme becomes clearer. Register your details with us here and we will let you know when more information becomes available.
