Eighteen months into the main construction phase, National Grid reports strong progress on substations, pylons and community funding along the Yorkshire GREEN route.

The Yorkshire GREEN project has chalked up a series of significant construction milestones 18 months after the principal works began, with activity advancing well across the corridor.

Since the main construction phase started in January 2025, teams have broken ground on new substations at Overton and Monk Fryston, installed 28 permanent pylons, and strung around 25 kilometres of new overhead electricity lines.

In addition, eight 200 tonne supergrid transformers have been delivered and installed, marking a key step in bolstering the region's electricity network.

Yorkshire GREEN forms part of The Great Grid Upgrade, the most substantial overhaul of the electricity system in a generation. With homes, businesses and public services consuming more electricity, and increasing amounts of clean energy joining the grid, projects like this are designed to expand capacity and maintain reliable supplies across Yorkshire.

National Grid said it is committed to ensuring host communities see clear and lasting benefits. As construction continues, the programme is supporting contractors across Yorkshire, helping to create skilled jobs and opening opportunities for local businesses.

The project has also awarded nearly £500,000 to local projects and initiatives. Organisations in East Riding and North Yorkshire have recently received funding for new play facilities, outdoor fitness equipment and broader community improvements.

These investments are intended to deliver practical benefits for communities along the route as the region’s electricity network is upgraded.

Activity is set to remain brisk through 2026. Works are ongoing at the Overton and Monk Fryston substations, and minor upgrades at Osbaldwick Substation are due to be completed over the summer.

Along the route, installation of new pylons and overhead lines is progressing between Shipton and Overton, with this section expected to finish later this year ahead of connection to the new Overton Substation. Between Overton and Moor Monkton, teams are constructing new infrastructure, dismantling older lines and beginning to remove temporary pylons. Further north, between Monk Fryston and Lumby, crews are continuing to build new permanent pylons and lines while removing older infrastructure around the Monk Fryston Substation site.

As major works conclude, reinstatement activity is starting to restore land along the route. National Grid will also undertake measures to leave the local environment and wildlife habitat in a 10% better condition than they were found. The new infrastructure is scheduled to begin coming online in 2027, with all works and reinstatement anticipated to be completed in 2028.
