The Queensland – New South Wales Interconnector (QNI) is a 330 kV AC interconnection between New South Wales and Queensland, Australia. The link was commissioned in 2001. It consisted of double-circuit 330 kV lines between Armidale, Dumaresq, Bulli Creek and Braemar, and a double-circuit 275 kV line between Braemar and Tarong.[1] The original maximum transfer capacity was 300 to 350 MW in both directions. This has been progressively increased to 700 MW from New South Wales to Queensland and 1,200 MW from Queensland to New South Wales.[2] The interconnector is operated by TransGrid and Powerlink Queensland.
