About Kiln Lane substation
We are building a new 400 kV substation near Friston, which will connect ScottishPower Renewables' (SPR) East Anglia ONE North and East Anglia TWO offshore wind farms to our transmission network.
The Secretary of State approved the construction of the Kiln Lane substation in March 2022, as part of SPR's applications for the two wind farms.
As part of the project, we need to:
construct the new Kiln Lane substation
modify the existing overhead line closest to the substation, by removing one existing pylon and constructing two new pylons
build two temporary pylons to allow the safe operation of the existing line during construction, which will be removed once construction is complete
make small changes to the equipment on up to 12 existing pylons on the existing overhead line.
About The Great Grid Upgrade
The new Kiln Lane substation is a key part of The Great Grid Upgrade - the largest overhaul of the electricity grid in generations. The Great Grid Upgrade will provide homes and businesses with secure, cleaner, home-grown British energy from more affordable sources.
What's happening now?
We're setting up our working area in phases over the summer, preparing the construction area from mid-July to September 2026.
Main construction will then begin in late 2026, and we expect to complete construction in 2028.

Community Fund
National Grid has a long-standing commitment to the communities we work alongside, and we want to ensure lasting benefits for the people and places that host our infrastructure.
Shaped by the community, for the community, the fund will be designed to reflect local needs and developed in line with government guidance.
If Sea Link is approved, we will deliver a Suffolk Community Fund of £1.06 million. In Suffolk, the first £530,000 of funding is guaranteed, as we already have planning approval for Kiln Lane substation. A further £530,000 would be available if Sea Link is approved.
By taking part in a short survey, you'll help us understand what's most important to you and how the funding can make a positive, lasting impact.
The survey will close on 5 August 2026, after which all feedback will be reviewed. Your feedback will help shape how the fund is designed and delivered, including the types of projects and initiatives it could support.

Our link to other projects in the area
Our separate Sea Link project will connect into the Kiln Lane substation, if it is consented. You can find out more on our separate Sea Link website.
SPR will also build two other substations next to Kiln Lane substation, which will support the initial conversion of energy generated from their offshore wind farms.
