Terranora interconnector (formerly named Directlink) is a high voltage direct current electricity transmission line between Mullumbimby, New South Wales (28°34′15″S 153°27′8″E / 28.57083°S 153.45222°E) and Bungalora, New South Wales (28°15′20″S 153°28′20″E / 28.25556°S 153.47222°E) in Australia. It is one of the two interconnections used to trade electricity between New South Wales and Queensland (the other one is the Queensland – New South Wales Interconnector). For environmental protection reasons it is implemented as underground cables.
The interconnector was developed by a joint venture of NorthPower (later Country Energy), TransÉnergie–a subsidiary of Hydro-Québec, and Fonds de solidarité FTQ. The reason behind the interconnector was the power shortage in Southern Queensland and surplus capacities in New South Wales. It was commissioned in December 1999 and it started operations in April 2000. It was the first time that transmission systems of New South Wales and Queensland were linked. The construction cost US$70 million.
