"Octopus Australia, an offshoot of British clean energy investment giant
Octopus Group, has struck deals for the purchase of two major battery projects,
one a massive facility of up to 4.8 gigawatt-hours in NSW, and the other a
smaller solar-battery hybrid project in Queensland.

Octopus is buying the Hanworth battery project near Bannaby, west of Bowral,
from development company Enervest, which at full scale will deliver 1.2
gigawatts (GW) and 4.8 gigawatt-hours (GWh) of storage capacity. If built now
it would rank as the biggest in the country.

It is also buying the Dunmore hybrid project in Queensland from Korean giant
Samsung, which will combine a 300 megawatt (MW) solar farm paired with a 150
MW, 300 MWh battery. Together, the projects would represent investment of more
than $3 billion once built.

“Australia still needs new power stations to replace ageing coal plants. The
difference is that today we can build them using a mix of solar, wind and
batteries instead of smokestacks,” Octopus Australia managing director Sam
Reynolds said in a statement.

“By owning and operating our projects as one portfolio, we can deliver reliable
power every day of the year – not just when the sun shines or the wind blows.
This is about replacing coal with clean energy that works in the real world.”"
