Overview

The North London Reinforcement (NLR) project will deliver a critical upgrade to our electricity transmission network, by doubling capacity to meet growing demand across the region and support energy security.

Currently, there is not enough transmission capacity on our existing overhead lines, forcing significant increases in energy demand to be met from non-renewable sources. We will be increasing voltage along the route from 275 kV to 400 kV and modernising substation technology that has served the area for over sixty years, enabling it to support greater volumes of energy from renewable sources, creating the foundation for a reliable, sustainable energy future.

NLR was approved in May 2014 following extensive public consultation, and we remain committed to meaningful engagement with local communities throughout the project's delivery. We will continue to work with communities to ensure the public is informed about the need for NLR and the works that will be taking place, and where we are minimising disruption where possible.

NLR is a part of The Great Grid Upgrade, the largest overhaul of the electricity grid in generations. It will play a significant role in meeting the UK Government’s plans to power all homes and businesses with green energy by 2030.
