A 50/50 joint venture (JV) between the construction engineering firms Clough and Elecnor has secured a contract worth A$1.5bn ($1.08bn) for TransGrid’s Project EnergyConnect, a proposed electricity transmission line in Australia.

The project involves the construction of a 900km long, 330kV above-ground transmission line from South Australia (SA) to New South Wales (NSW) in south-eastern Australia with an added connection to Victoria (Red Cliffs).

The transmission line is being jointly developed by an electricity transmission specialist, ElectraNet and NSW’s transmission network manager and operator, TransGrid.

Under the contract, the JV, named SecureEnergy, will provide the engineering, procurement and construction services for TransGrid’s portion of the project.

The portion involves the installation of four substations and about 700km of 330kV transmission line.

Elecnor Australia managing director Joseph de Pedro said: “Secure Energy entering the Power Transmission sector in Australia represents a big milestone for the industry and will help in bringing more innovation and know-how to the market as well as upskilling the Australian workforce to support the upcoming electricity network transformation.”

The proposed project aims to support 5.3GW of power generated by 30 wind and solar projects that are planned to be developed in SA, NSW and Victoria.

It includes a 330kV transmission line starting from the existing Robertstown substation to a proposed new substation at Bundey about 10-15km northeast.

A new 330kV double circuit HVAC transmission line from Bundey substation will continue till Buronga and will end at Darlington Point.

Clough CEO and managing director Peter Bennett said: “The Australian energy sector is undergoing development of the infrastructure that will sustain it through the future growth of our nation.

“Clough is extremely proud to be selected for this project and to continue to be part of the Energy portfolio.”

Furthermore, the government of NSW has been strongly supporting the project which has been declared as Critical State significant infrastructure (CSSI).
