Connecting to cheaper, cleaner more reliable electricity


The approval of the SA-NSW Interconnector by the Australian Energy Regulator (AER) is a significant milestone in a project that will deliver cheaper, cleaner and more reliable electricity to South Australian households and businesses.

The SA-NSW Interconnector is a key pillar of the Marshall Government’s energy policy and the first interconnector built in Australia for 15 years will deliver billions of dollars of investment in renewable energy projects and hundreds of jobs along its route.

The Australian Energy Market Operator (AEMO) has deemed the 330kV interconnector to be built by ElectraNet and Transgrid between Robertstown and Wagga Wagga as a “no-regrets” measure which is a priority project in the national transmission plan.

“The Australian energy landscape will be completely transformed during coming decades and the lesson of the recent past is that we need to take actions ahead of time to secure the best outcome for consumers,” said Minister for Energy and Mining Dan van Holst Pellekaan

“The Regulatory Investment Test for Transmission (RIT-T) approval shows that even when rigorously stress-tested, the interconnector delivers cheaper electricity to South Australians.

“As new wind and solar projects, above those in the 2018 base case, come online greater cost benefits will flow to households and businesses.

“This project will unlock huge new renewable energy zones in South Australia and NSW with AEMO reporting there are more than 5000 MWs of planned renewable energy projects in close proximity to the interconnector.

“The SA/NSW Interconnector will help Snowy 2.0 deliver the massive supplies of renewable energy to fulfil its role as the nation’s battery.

“South Australia is determined to be a good global citizen, and become a net exporter of renewable energy as part of our aspiration of net-100% renewables in the 2030’s.

“The AER’s determination shows that South Australian wind and solar power can play a bigger national role with the interconnector, delivering more jobs and growth in South Australia.

“The SA/NSW Interconnector will also improve South Australia’s electricity systems resilience to external shocks.

“With climate change leading to increased extreme weather conditions such as storms, floods and fires, being interconnected with just Victoria leaves South Australia at real risk of becoming disconnected from the rest of the market. “The SA/NSW Interconnector makes us part of the loop, giving South Australia two connections to the National Electricity Market.”
