Project EnergyConnect is a proposed electricity transmission line connecting the South Australia and New South Wales districts of the National Electricity Market in Australia. Riverlink was a previous working title for the project, drawn from a proposal first raised in 1999.[1] The Australian Energy Market Operator used RiverLink in its proposal for this interconnector, but the transmission companies in South Australia (ElectraNet) and New South Wales (TransGrid) now call it EnergyConnect.

South Australia and New South Wales already each have connections to Victoria, which also has a connection across Bass Strait to Tasmania, and New South Wales also has connections to Queensland. The proposed connection between New South Wales and South Australia would provide resilience and redundancy to the network. It is aimed to provide increased security of supply to South Australia and better access to renewable energy generation to New South Wales.[2]

Construction of the new interconnector is expected to cost A$1.52 billion. It will be 900 kilometres (560 mi) long, from Robertstown to Wagga Wagga, New South Wales. It is proposed to have a spur from Buronga to Red Cliffs in Victoria.[3] Assessment of the Regulatory Investment Test for Transmission (RIT-T) began in June 2019.[4]

The link endpoints are at Robertstown in South Australia where major transmission lines connect to the north and south of the state, and Wagga Wagga, the furthest west in New South Wales that the high voltage lines reach. The new high-voltage line is expected to improve the feasibility of more solar and wind farms in the areas traversed by the line.[5]

The Australian Energy Market Commission changed its rules in April 2019 to streamline the regulatory process for several network upgrades including Project EnergyConnect. The change allows the Australian Energy Regulator to consider the proposals concurrently.[6] ElectraNet established information hubs near the South Australian part of the route to consult the public about the detailed route.[7] One of the concerns is that the proposed route crosses Calperum Station which is home to a critically endangered species, the black-eared miner.[8] New South Wales put the project on a fast-track development process by assigning it "critical infrastructure" status.[9]
