About Grimsby to Walpole

Grimsby to Walpole is a 140 km overhead line between Northeast Lincolnshire and North Norfolk, needed to reinforce the network, and to connect new sources of electricity planned in the area, including offshore wind, solar, gas-fired generation, interconnectors, battery storage and subsea links from Scotland.

About The Great Grid Upgrade

The Great Grid Upgrade is the largest overhaul of the grid in generations and will future proof the Grid for years to come, facilitating the transition to a clean and affordable energy future. It will enable us to carry more clean, secure energy from where it is generated to where it is needed, boosting energy security and helping the nation become more self-sufficient. 

The Grimsby to Walpole proposals form part of The Great Grid Upgrade, aiming to enhance the grid's capacity to handle increased renewable energy, ensuring a reliable and sustainable power supply.

Why this is needed

The way we generate electricity has changed and is continuing to change. The existing network in the region does not have the capacity to deliver the required amount of electricity to where it is needed across the East Midlands. The existing network, built in the 1960s, is outdated and insufficient for new renewable connections. To meet future demands, we need to reinforce parts of the network.

Grimsby to Walpole is one of five new electricity transmission projects being proposed in Lincolnshire. Three are mainly offshore projects. Grimsby to Walpole is an overhead line project. We require these new reinforcement projects so we can continue to deliver a reliable, affordable network into the future, meet the rising demand for electricity and the connection of new renewable energy sources. 

These projects will connect our homes, businesses and public services to sources of home-grown renewable energy which can lower our electricity bills and make our country more energy secure.
