East Coast 400kV OHL Upgrade – Section 37 Application
The East Coast 400kV overhead line (OHL) upgrade is the second part of the phased onshore reinforcement on the East Coast. This onshore reinforcement comprises of works on existing infrastructure in both the SSEN Transmission and Scottish Power Transmission (SPT) area, with the majority of the works in the SSEN Transmission area.
The projected growth in generation capacity within the SSEN Transmission area gives rise to increased north to south power transfer requirements. In addition to the load driver, an asset condition assessment carried out in 2018 recommends re-conductoring the OHL between Kintore, Fetteresso, Alyth, Tealing and the SSEN Transmission/SPT border.
The East Coast 400kV OHL upgrade project will see 170km of the re-profiled 275kV circuits (following the East Coast 275kV OHL upgrade) upgraded to 400kV operation between Kintore, Fetteresso and Alyth as far as the SSEN Transmission/SPT border
SSEN Transmission has a licence obligation to invest in its existing assets to maintain network health and condition. SSEN Transmission also has a statutory duty under the Electricity Safety, Quality and Continuity Regulations 2002 to ensure that the electricity transmission network is fit for purpose.
On 29 January 2021 we submitted an application to Scottish Ministers for consent under Section 37 of the Electricity Act 1989 for the upgrading of the existing East Coast 275kV OHL to 400kV. We have been working closely with the Energy Consents Unit to ensure that, during the COVID-19 restrictions imposed by the UK and Scottish Governments, the application can be processed formally and in accordance with all relevant Regulations.
