Australia’s energy transition plans have been challenged by the delays in installing transmission lines tied to wind and solar farms. As a result, the country is now at risk of power shortages.
The Australian Energy Market Operator (AEMO) said the delay in commissioning dates for EnergyConnect could impact the power grid. The project involves building a 900 km long interconnector between South Australia and New South Wales with an added connection into Victoria.

The project is said to lower power prices and support the transition to a reduced carbon dioxide emission energy system. It is also significant as Australia’s power industry needs help meeting the government’s target of 82% renewable power by 2030. The primary challenge lies in expanding transmission networks to handle new renewable projects that are not in close proximity to the demand centre.
AEMO’s report said reliability risks have increased in Australia’s two biggest power-consuming states, New South Wales, Victoria, and South Australia.
CEO Daniel Westerman said AEMO would bid for backup supplies to support Victoria and New South Wales in an attempt to avoid supply gaps next summer, which usually starts in December for the southern hemisphere.
“While new generation and storage capacity continues to increase, project development and commissioning delays are impacting reliability throughout the horizon,” AEMO CEO Daniel Westerman said.
About 10,000 km of new and upgraded transmission line is required to prevent supply shortages, the operator said in a report.
