About the Project Contractor

SecureEnergy (a venture of Elecnor Australia) was awarded the engineering, construction and procurement (EPC) contract for a new 700km 330kv transmission line extending from Wagga Wagga NSW to the South Australian border of Transgrid's EnergyConnect project in June 2021. Construction on this project started in 2022 and is anticipated to be completed within the next 12 months.
Throughout the delivery phase, Elecnor has been committed to providing economic benefit to the local and Indigenous communities along the project route. As of May 2025, almost $240 million has been spent procuring good and services from businesses and suppliers based in the local government areas, and almost $18 m has been spent with First Nations groups and businesses.
