Wind power producer Infigen Energy will install a 25MW / 52MWh Tesla battery at the Lake Bonney Wind Farm in South Australia.

The company has entered into funding agreements with the South Australian Government and the Australian Renewable Energy Agency (ARENA) to co-fund the $38 million project, which will be built adjacent to Infigen’s existing 278.5MW wind farm.

The facility which will be connected to the National Electricity Market (NEM) via the Mayurra substation owned by ElectraNet and will enable   Infigen to firm at least an additional 18 MW of power depending on the customer load profile.

Infigen Chief Executive Officer Ross Rolfe said construction activities are expected to commence in the coming weeks.

“With the firming capability of the BESS Infigen will be able to expand its supply contracts from the Lake Bonney Wind Farm to additional commercial and industrial customers in South Australia, which is at the heart of our business strategy,” he added.

ARENA Chief Executive Officer Ivor Frischknecht said the battery will deliver flexible capacity and system security services, such as Frequency Control Ancillary Services (FCAS), to the electricity grid in South Australia.

“It is clear that grid scale batteries have an important role in stabilising the grid,” he continued.

“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.”

The project is supported by the SA Government and ARENA who have each committed $5 million in grant funding.
