Nationwide Grid PLC has utilized earlier than the Planning Inspectorate to construct a brand new transmission community that it says would energy as much as six million properties and companies in East Anglia.
The mission entails constructing “a brand new electrical energy transmission community improve between Norwich Fundamental substation in Norfolk through Bramford substation in Suffolk and a brand new Tilbury North substation into Tilbury substation in Essex”, Nationwide Grid mentioned in a press release on its web site.
“The Norwich to Tilbury mission will enhance electrical energy capability throughout East Anglia, a powerhouse of renewable power, notably offshore wind, however a area that has traditionally had restricted transmission infrastructure”.

The proposed line consists of 180 kilometers (111.85 miles) of high-voltage overhead and underground cables.
Nationwide Grid plans to begin development 2027. It expects the work to take round 4 years.
“As our demand for electrical energy grows the way in which we generate electrical energy is altering. This mission will join our properties, companies and public providers to sources of home-grown British power which can decrease our electrical energy payments within the long-term and make us extra power unbiased”, mentioned mission director Simon Pepper.
Nationwide Grid mentioned the submitted plan accounted for outcomes from public consultations. “Over the previous few years, a number of rounds of public session have been held with native authorities, elected officers, technical consultees, affected landowners and native communities”, it mentioned.
The Norwich to Tilbury mission is a part of Nationwide Grid’s The Nice Grid Improve, which consists of 17 main infrastructure initiatives throughout England and Wales. These initiatives would develop and improve the community to allow renewables integration.
“These initiatives are important to extend Britain’s power safety and meet rising demand for electrical energy within the years forward”, Nationwide Grid mentioned.
Final yr the Nationwide Grid Electrical energy System Operator unveiled a GBP 58 billion ($67.33 billion) plan to boost Nice Britain’s era capability with renewable power, with the last word objectives of assembly rising demand and attaining energy decarbonization.
The plan goals to attach an extra 21 gigawatts (GW) of wind capability offshore Scotland to the grid, along with a earlier plan of 23 GW. “This is able to imply that there can be 86 GW of offshore wind, making Britain a world chief in offshore wind and floating offshore windfarms”, the system operator mentioned in a press release accompanying the plan. “For comparability, the Worldwide Renewable Vitality Company states that there’s at the moment 63GW of offshore wind put in globally.
“In whole there can be over 30 GW of offshore wind in Scottish waters in comparison with 6 GW of peak electrical energy demand in Scotland in 2035. The plan strikes that energy to the place it may be used – each round Scotland and throughout Britain”.
The system operator famous within the plan that whereas Britain achieved vital development in renewable power capability, funding in transmission capability had not caught up, resulting in wastage.
The UK had 61.37 GW of put in renewable era capability as of the primary quarter of 2025, in line with authorities information.
“Britain’s electrical energy wants are set to rise considerably (by as much as practically 65 per cent) by 2035, as our on a regular basis lives change into extra digitally intertwined and we transfer in the direction of extra electrified warmth and transport choices”, the system operator mentioned within the new plan.
“Coupled with this, the UK authorities has set an ambition to have a completely decarbonized electrical energy system by 2035.
“This implies producing extra electrical energy and transporting it in a wiser, cheaper, and greener means. A key a part of that is effectively connecting the offshore wind being constructed round Nice Britain in a coordinated means”.
The federal government’s aim is to succeed in 50 GW of offshore wind capability by the tip of the last decade.
The brand new plan additionally seeks to develop transmission capability to match the expansion in renewable era.
After assessing about 200 community choices, the plan included an “optimized high-level community design”. The design beneficial “over 3 times as a lot undersea cabling laid in contrast with new onshore routes, linking electrical energy being produced within the seas round our shores onto the mainland at applicable factors”.
The system operator additionally proposed reinforcing grid integration between North East Scotland and North West England by means of a brand new arterial transmission route.
“Moreover, by enhancing the capability between the west coast and the east coast of England, the hyperlinks between the first arterial routes are strengthened”, the plan mentioned. “This elevated coast-to-coast connectivity balances energy flows throughout the nation, bettering safety and making certain that renewable energy can at all times be accessed no matter the place it’s generated”.
The system operator has been renamed Nationwide Vitality System Operator after Nationwide Grid offered it to the federal government final yr to create an unbiased operator.
