The 143rd pylon, located in Crooks Marsh, was completed on 25 June. It is 50 metres tall and joins 26 traditional lattice pylons that have been built in Avonmouth over the past two years and which will form part of the UK's high voltage transmission network. 

Once the conductors are installed it will connect into Seabank substation as the northernmost section of the Hinkley Connection, which will bring low carbon energy to 6 million homes and businesses across the country. 

The Hylton Castle substation will provide a new grid connection for Nissan, AESC UK and Sunderland City Council’s ambitious EV36Zero electric vehicle hub at IAMP, which brings together EV manufacture, battery production and a renewable energy microgrid.

Once completed and energised in 2026, Hylton Castle substation will – with its three new 100-tonne supergrid transformers and advanced control systems – reinforce the network in the region and create electricity capacity on site equivalent to powering around half a million homes for a day.

This year’s five-mile walk will be exploring Roundway Hill, including the site of the Civil War Battle of Roundway Down and the Iron Age hillfort, Oliver’s Castle.

Members of the team will be on hand to answer questions and explain why and how the landscape around the Millennium White Horse has been singled out for special attention. 

National Grid is also moving its five remaining webinars until after the general election takes place.

Norwich to Tilbury is needed to connect new sources of low carbon energy to homes and businesses across Britain and help reduce our reliance on fossil fuels. It will play a key role in addressing the climate emergency and helping achieve the UK’s targets for net zero.

National Grid is preparing for the delivery of a large supergrid transformer to the site of a new grid supply point (GSP) substation between Butler’s Wood and Waldegrave Wood, off the A131 south of Sudbury. The GSP substation is needed so that existing 132 kV overhead line can be removed as part of the construction of the planned Bramford to Twinstead Reinforcement. 

National Grid today announced plans to invest an estimated $75 billion* across the company’s service territory in the UK and US over the next five years, with nearly half of the funding dedicated to US energy system improvements in Massachusetts and New York. This significant step up to approximately $35 billion* of investment represents an increase of more than 60% on National Grid’s investment in the region in the last five years.

The eight-week public consultation, which starts 14 May and runs until 9 July, will share proposals for Chesterfield to Willington, a new 60-kilometre, high voltage electricity power line running between a new substation at Chesterfield (part of a separate project Brinsworth – High Marnham) and an existing substation at Willington.
