The wind farm is south of, and contiguous with, Canunda Wind Farm. Both are built along the Woakwine Range - a line of stabilised sand dunes that once were coastal. The nearest large town is Millicent.

The owner of the Lake Bonney Wind Farm is Infigen Energy, previously known as Babcock and Brown Wind Partners. Wind turbines are serviced under a post-warranty service agreement[3] by the Original Equipment Manufacturer Vestas.

Battery storage

It was announced in August 2018 that a 25 MW / 52 MW·h battery would be added to the wind farm to provide firmer commitments to provide electricity, system security and ancillary services to the electricity grid. The battery will cost A$38 million to install, including $5 million from the government of South Australia and $5 million from the Australian Renewable Energy Agency (ARENA). It is connected to the Mayurra substation.[4] Like the similar Hornsdale Power Reserve, the battery will operate independently of the wind farm in the electricity market, and connect to the grid at the same point as the wind farm.[5] Construction of the battery was completed in May 2019,[6] and testing began in November 2019.[7] In 2020, its Frequency Control Ancillary Service (FCAS) earned $230,000 per MWh installed.[8]
