What is the Basslink interconnector?
Basslink is a 400kV DC electricity interconnector that allows the trade of electricity between Tasmania and the National Electricity Market. The interconnector is rated to transmit 500 megawatts (MW) of energy on a continuous basis in either direction and up to 630MW export from Tasmania for limited periods.
Who owns Basslink cable?
the Keppel Infrastructure Trust
Basslink is owned by the Keppel Infrastructure Trust, which is listed on the Singapore Stock Exchange, of which one third is held by Temasek, the $350 billion sovereign wealth fund of the Singapore government, and two thirds by the public.
Who built Basslink?
Basslink is owned by Keppel Infrastructure Trust, a listed entity on the Singapore stock exchange. The interconnector business and its subsidiary business Basslink Telecoms are managed locally by staff based in Melbourne, Traralgon and George Town.
Where does Tasmania get its electricity?
Tasmanian electricity generation comprises hydro-electric, gas-fired generation, wind and embedded5 generators. In 2019-20, just under 90 per cent of electricity generated was from hydro-electric systems, with around 10 per cent accounted for by wind generation.
How thick is the Basslink cable?
The cable being used for the Basslink is 15 cm thick. It resurfaces on Ninety Miles Beach in Victoria. There, it runs through a duct under the beach, continues for a few kilometers as an underground cable, and finally emerges as an above-ground line running 70 km to Loy Yang.
Why is DC used for undersea cables?
For transmission of large amounts of electric power through submarine cables, direct current(DC) is preferred, because DC cables require less reactive power than submarine AC cables. As well, for three phase AC-cables three conductors are necessary, while for DC only 1 or 2 conductors are required.
Is Basslink a regulated asset?
We understand, however, that Basslink in essence currently operates as a quasi-regulated asset (i.e. bids in at zero and HydroTas’s bidding behaviour is constrained).
Does Tasmania have natural gas?
The Natural Gas industry in Tasmania is highly regulated with many controls and standards in place to ensure your safety. Tas Gas Networks (TGN) is delivering natural gas to homes and businesses in Tasmania. Their network makes gas available to approximately 46,500 of the state’s commercial and residential customers.
Is Tasmania fully renewable?
Tasmania reached net-zero in 2015, because its vast forests and other natural landscapes absorb and store more carbon each year than the state emits. And in November last year, Tasmania became fully powered by renewable electricity, thanks to the island state’s wind and hydro-electricity projects.
What are HVDC cables?
Our high voltage direct current (HVDC) offshore cable systems enable efficient long-distance transmission at high power levels, interconnecting regions and countries and electrified oil and gas platforms. This technology also allows a secure and stabilising connection to existing electricity grids.
What is the thickest cable in the world?
The deepest submarine power cable in the world runs in the Tyrrhenian sea, 1,600 meters below sea level. It connects Sardinia with the Italian mainland. The project is called SA. PE.
