Upgrading the Queensland-NSW Interconnector (QNI) will boost interstate transmission capacity and increase power flow on existing lines. This will make it easier and more efficient to share power generation across the National Energy Market, which will help put downward pressure on customer bills.
It will also enhance network reliability ahead of the forecast closure of Liddell power station in 2023.
The project has been identified as a priority by both the Australian Energy Market Operator in the 2020 Integrated System Plan and by the State Government in the NSW Transmission Infrastructure Strategy.
Please see below for an indicative list of key dates for the project:
