Lake Bonney Wind Farm is a wind farm near Millicent, South Australia, Australia. 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 project was built in three stages. Stage 1 comprises 46 turbines each having a rated capacity of 1.75 MW (total 80.5 MW) and was finished in March 2005. Construction of Stage 2 began in November 2006 and was finished around April 2008. Stage 2 comprises 53 turbines of 3 MW (total 159 MW). Stage 3 comprises 13 turbines of 3 MW of total 39 MW).[https://web.archive.org/web/20091027104439/http://geocities.com/daveclarkecb/Australia/WindSA.html Wind power and wind farms in South Australia: Wind in the Bush] Stage 3 construction commenced in February 2009 and was commissioned in September 2009.{{Cite web|title=Lake Bonney Wind Farm Stage 3|url=https://www.aurecongroup.com/projects/energy/lake-bonney-wind-farm-stage-3|access-date=2021-09-05|website=www.aurecongroup.com|language=en}}
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{{Cite web |url=http://infigenenergy.com/media/docs/Infigen-Executes-Post-Warranty-Services-Agreements-with-Vestas-9f99efc0-3389-484a-9c71-8535fd0f8037-0.pdf |title=INFIGEN EXECUTES POST-WARRANTY SERVICES AGREEMENTS WITH VESTAS |access-date=22 January 2016 |archive-url=https://web.archive.org/web/20120602052108/http://www.infigenenergy.com/media/docs/Infigen-Executes-Post-Warranty-Services-Agreements-with-Vestas-9f99efc0-3389-484a-9c71-8535fd0f8037-0.pdf |archive-date=2 June 2012 |url-status=dead |df=dmy-all }} by the turbine manufacturer Vestas.
Battery storage
It was announced in August 2018 that a battery storage power station would be added to the wind farm to provide firmer commitments to provide electricity, system security and ancillary services to the electricity grid. The project would cost {{AUD|38 million}} to install, including $5 million from the government of South Australia and $5 million from the Australian Renewable Energy Agency (ARENA). The battery is rated at 25 MW and 52 MW·h, and is connected to the Mayurra substation.{{cite news |url=https://indaily.com.au/news/2018/08/15/another-big-battery-to-be-built-in-sa/ |title=Another big battery to be built in SA |date=15 August 2018 |accessdate=15 August 2018 |first=David |last=Washington |newspaper=InDaily}} 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.{{cite news |url=https://www.abc.net.au/news/2018-11-15/sa-tesla-battery-site-on-track-to-charge-may/10496282 |title=South Australia's $38 million Tesla battery site on track to charge in 2019, giving Infigen more opportunities |work=ABC South East SA |first=Glen |last=Moret |date=15 November 2018 |access-date=25 January 2019}} Construction of the battery was completed in May 2019,{{cite web |url=https://www.infigenenergy.com/lake-bonney-battery-energy-storage-system-0/ |publisher=Infigen Energy |accessdate=30 August 2019 |title=Lake Bonney Battery Energy Storage System}} and testing began in November 2019.{{cite web |last1=Parkinson |first1=Giles |title=Lake Bonney battery charges up for first time in South Australia |url=https://reneweconomy.com.au/lake-bonney-battery-charges-up-for-first-time-in-south-australia-37264/ |website=RenewEconomy |language=en-AU |date=5 November 2019}} In 2020, its Frequency Control Ancillary Service (FCAS) earned $230,000 per MWh installed.{{cite web |last1=Parkinson |first1=Giles |title=Dalrymple big battery delivers biggest bang for megawatt hour of storage |url=https://reneweconomy.com.au/dalrymple-big-battery-delivers-biggest-bang-for-megawatt-hour-of-storage/ |website=RenewEconomy |language=en-AU |date=23 February 2021}} By contrast, arbitrage (buy low, sell high) had earned a third of the battery's build cost by 2024.{{cite web |last1=Hall |first1=Max |title=BNEF: Australian utility appetite for big batteries rising |url=https://www.ess-news.com/2025/03/28/bnef-australian-utility-appetite-for-big-batteries-rising/ |website=Energy Storage |date=28 March 2025 |quote=earned 33% of its capex in arbitrage revenue}}
