Summary of the contracting process

The National Grid Electricity Transmission PLC and SP Transmission PLC are jointly procuring Engineering, Procurement & Construction contracts for the Torness to Hawthorn Pit HVDC Link, a high-voltage direct current transmission project connecting Scotland and England. The procurement process is in the "award" stage with a selective procurement method. The project involves the construction of converter stations, high-voltage cables, and civil works over a total route length of approximately 196 km. The contract covers design, engineering, construction, testing, commissioning, and maintenance of the HVDC Link between Scotland and England. The deadline for the tender period was on 4th March 2022. This opportunity is within the works industry category and is relevant to businesses specialising in construction work for electricity power lines.

The Torness to Hawthorn Pit HVDC Link project presents significant business opportunities for large-scale suppliers such as GE Vernova & Mytilineos and Prysmian Powerlink SRL. The contracts are structured in 3 Lots, offering options for participating in either or both converter station and cable system projects. The procurement process involves joint venture arrangements, with potential for early works awards. Successful contractors will be responsible for detailed design, installation, and commissioning to ensure the full operation of the HVDC Link by Q4 2027. Businesses with expertise in electricity distribution, high-voltage cable installation, and construction of power lines are well-suited to compete in this tender for substantial financial value, providing an opportunity for growth and expansion within the electricity transmission sector.
