Murphy has commenced work on the Eastern Green Link 1, a major electricity infrastructure project valued at £2.5 billion. This initiative, a joint venture between SP Energy Networks and National Grid Electricity Transmission, involves the installation of a 196km high-voltage subsea electricity cable connecting Torness in East Lothian, Scotland, to Hawthorn Pit in County Durham23.
Project Details
- Designing, procuring, and constructing a new 400kV Gas Insulated Switchgear (GIS) substation adjacent to the existing National Grid Hawthorn Pit 275kV Substation
- Modifying the existing overhead line near Hawthorn Pit Substation to create a connection point
- Designing, procuring, and constructing a new 400kV Cable Connection between the new and existing substations
- Designing, procuring, and constructing two new 275kV connections between the new and existing substations
- Designing, procuring, and constructing a new 400kV GIS bay in the existing Norton substation and modifying the existing overhead line connection, which involves oversailing a Network Rail asset23
Project Timeline and Significance
The Eastern Green Link 1 represents a significant step towards expanding and strengthening the UK’s electricity network. By creating a new “electric superhighway”, it aims to enhance the country’s energy infrastructure and improve energy security, facilitating the transition to a more sustainable and resilient power grid.
“We will be responsible for the 400kV substation works package for National Grid Electricity Transmission (NGET), working collaboratively with the wider project to expand the electricity network. This project is crucial for meeting Britain’s future energy infrastructure needs and strengthening energy security”. -Liam Corr, Managing Director of Energy at Murphy
