EnergyConnect

Elecnor Australia (formerly SecureEnergy) was awarded the engineering, construction and procurement (EPC) contract for the new 700km 330kv transmission line extending from Wagga Wagga NSW to the South Australian border of Transgrid’s EnergyConnect project in June 2021.

In its entirety, EnergyConnect includes a new 900km electricity transmission line, known as an interconnector, that will connect power grids across three Australian states, driving competition in the wholesale electricity market. The interconnector is being built between Wagga Wagga in New South Wales and Robertstown in South Australia, with a connection to Red Cliffs in Victoria.

This backbone infrastructure for the future Southwest NSW Renewable Energy Zone will enable connection of a further 4950MW of generation capacity, save NSW customers $180 million a year and create 1,500 new construction jobs in regional NSW.

Watch the first towers being installed on the NSW–Western Section.
