The public consultation has been extended until 11:59pm on Tuesday 17 September 2024 to give people additional time to have their say and provide feedback.

Building a new power line between Chesterfield and Willington will increase the capacity in the centre of the country, enabling cleaner, greener energy to be carried around the network, benefiting homes and businesses in Derbyshire and beyond, and supporting the UK’s offshore wind and net zero targets.

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.
