Project details / Share



South Australia, Victoria and New South Wales, Australia


Project EnergyConnect is a high-voltage electricity interconnector between Robertstown, South Australia and Wagga Wagga, NSW, with an added connection to Victoria (Red Cliffs).

The project involves the construction of approximately 900km of high-voltage above-ground transmission line complete with four substations. It will reduce the cost of providing secure and reliable electricity transmission between NSW and SA while facilitating the longer-term transition of the energy sector to low-emission energy sources.

The commercial strategy is to engage an engineering procurement and construction contractor to deliver the entire project with TransGrid personnel managing the successful contractor. Construction is now well advanced in NSW, with final contract closeout expected in 2024.

TSA Riley is providing project controls management including the:

  • set up of cost management procedures within the project
  • evaluation of the tenderer commercial and pricing schedules
  • monthly forecasting reporting and updating of the schedule
  • submission of the monthly progress claims to the South Australian Government
  • drafting of the cost management plan.
