On the 3rd of March 2020 we held a public consultation in Kintore regarding our proposals to submit a new planning application for a 400kV Air Insulated Swtichgear (AIS) substation at Leylodge, Kintore. Prior to submitting a planning application, SSEN Transmission have committed to return to consult with members of the local community, focusing on a more detailed GIS substation design. More information on all these developments and the drivers for these proposed works can be found here.Īt present, SSEN Transmission are currently considering two options for the design of the proposed Kintore substation, one of which involved the use of Air Insulated Switchgear (AIS) equipment and an alternative which uses Gas Insulated Switchgear (GIS) equipment.Īs part of our commitments and responsibilities to the decarbonisation of the GB electricity network it has been the view of SSEN Transmission that an AIS option is the preferred solution, however due to recent advancements and innovations of switchgear technology, SSEN Transmission has been provided with an opportunity to consider a lower carbon potential GIS substation.Ĭurrently we have consulted with members of the local community on a more developed AIS solution, whilst introducing the potential opportunities that exist regarding recent switchgear advancements. To ensure the security and quality of supply of electricity in the transmission network we are proposing several upgrades and reinforcements across the North East and East Coast of Scotland. This involves a phased development of a new substation operating at 400kV, with ‘Phase 1’ completed to tie in with the network north of Kintore in October 2023 and ‘Phase 2’ completed for the network south of Kintore energising to 400kV operation in 2026. To allow this, the North East and E ast Coast networks require reinforcement via a new substation at Kintore. The NOA in 20 has provided “Proceed” signals for the East Coast and North East network to be reinforced to 400kV operation. This is called the Networks Options Assessment (NOA). A number of significant projects connecting to the transmission network has triggered the need for a 400kV substation at Leylodge, Kintore.Įach year the electricity system operator (National Grid ESO) assesses all proposed network reinforcements across Great Britain and provides a recommendation on whether these proposals should proceed.
