"The founders of New Zealand solar developer Far North Solar Farm have
announced an ambitious plan to build a 2-3GW high-voltage direct current (HVDC)
subsea cable between New Zealand and Australia.
Designed to facilitate the trade of electricity between the two countries, the
2-3GW HVDC submarine cable would extend 2,600km across the Tasman Sea and help
to increase generation and transmission capacity in both markets.
It would also support the increase of wholesale supply and retail competition,
and accelerate the development of renewable energy in the two countries.
Taslink is the brainchild Australia’s John Telfer and New Zealand’s Richard
Homewood, who founded Far North Solar farm in 2019.
Expected to cost upwards of $10 billion, the subsea cable would link the two
countries from a point south of Auckland in the north of New Zealand’s North
Island, to Newcastle on the New South Wales central coast.
The cable would be both the deepest and longest of its kind in the world and
would be able to take advantage of the two countries’ close geographic and
temporal proximity.
“The thing about New Zealand and Australia is that we have a two hour time
difference, so we have a morning peak followed [two hours later] by Australia’s
morning peak,” Richard Homewood told Radio New Zealand.
“We also have our peak demand in winter time (for heating), when we have cold
and dry winters, whereas Australia has the highest demand on hot days in summer
(for cooling).”
These sympathetic parallels would see Taslink buy power from one country at a
cheaper rate and sell it to the other, and allow surplus Australian power to be
traded to New Zealand when it’s needed, and vice versa.
“We will be purchasing power from the electricity markets in both countries, so
we will have generators in New Zealand producing power that could be purchased
by Taslink and sold into the Australian market,” Homewood continued.
“On the same way you could have generators in Australia… Say, solar, because
Australia has an abundance of daytime solar.”"
