Construction of the A$38 million ($27.5 million) Tesla Powerpack battery is expected to begin "in the coming weeks", the developer said.
It is due online in the first half of 2019. Infigen received A$10 billion in funding from the South Australian government and the Australian Renewable Energy Agency (Arena).
It comprises 46 Vestas V66 1.75MW and 66 Vestas V90 3MW turbines.
Infigen said the battery would mean it could secure additional supply contracts as it allows firmer energy production. It also opens up the possibility of providing ancillary services to the grid.
"It is clear that grid-scale batteries have an important role in stabilising the grid.
"The co-location of a battery with a wind farm provides an opportunity for Infigen to pursue regulatory changes that could improve revenue outcomes for grid-scale batteries, helping to becoming more competitive," said Arena CEO Ivor Frischknecht.
Despite the continued political indifference to renewables deployment in Australia, the market is fast becoming a leader in battery storage deployment at renewable energy projects.
Tesla provided a 100MW/129MWh battery system to Neoen’s 309MW Hornsdale wind project, also in South Australia.
Developer Neoen also arranged funding for another 20MW Tesla battery for a 194MW wind project in Victoria, south-east Australia.
In June, the Queensland government granted development approval for a 1GW renewable energy project combining wind, solar and storage.
Arena, meanwhile, part-funded a project on Tasmania to examine how wind projects could provide frequency control services without batteries.
