The Hornsdale Wind Farm is an electricity generator in the locality of Hornsdale in the south-west of the Narien Range, north of Jamestown, South Australia. It consists of 99 wind turbines with a generation capacity of 315 megawatts (422,000 hp)[2]. The plant is owned and operated by Neoen, a French renewable energy company.

The electricity generated by Hornsdale Wind Farm is contracted to be supplied to the Australian Capital Territory.[3]

Construction

The "Balance of Plant" civil engineering and site works for the wind farm was performed by Catcon for all three stages of construction.[4] The wind turbine generators were imported from Denmark, and the towers from Vietnam.[5] They were commissioned by Siemens Australia.[6] Before the whole wind farm was commissioned, Hornsdale was generating 86 MW immediately prior to the 2016 South Australian blackout in September 2016.[7]

Artwork

Two of the towers feature paintings by people from the indigenous peoples of the region. Jessica Turner is a Nukunu woman whose artwork represents the story of the serpent's role in forming aspects of the landscape, particularly waterholes. Chris Angrave and Louise Brown are Ngadjuri people who depicted how the Mungiura were found in hilly country, peering over the top of windbreaks before a storm, and blowing hard, which caused a whirly wind.[8]

Hornsdale Power Reserve

The Hornsdale Power Reserve is a grid-connected battery complex co-located with the Hornsdale Wind Farm. It was built by Tesla, Inc. for a cost to Tesla of about US$50 million.[9][10]

It is owned[11] and operated by Neoen, with the government having the right to call on the stored power under certain circumstances.[12] It provides a total of 129 megawatt-hours (460 GJ) of storage capable of discharge at 100 megawatts (130,000 hp) into the power grid. It provides several services to the grid:[13]

The battery construction was completed and testing began on 25 November 2017. It was connected to the grid on 1 December 2017.[19] This easily beat Elon Musk's wager of "100 days from contract signature",[10][20][21] which started when a grid connection agreement was signed with ElectraNet on 29 September 2017.[9] Tesla had already begun construction, and some units were already operational by the time the contract was signed.[15] Due to the project's success and the area's demand for stable electricity output, the project was expanded by 50% in November 2019. The upgraded system is capable of discharge at 150 megawatts (200,000 hp) into the power grid.[22]

But in reality, the response from the Tesla big battery was even quicker than that – in milliseconds – but too fast for the AEMO data to record. Importantly, by the time that the contracted Gladstone coal unit had gotten out of bed and put its socks on so it can inject more into the grid – it is paid to respond in six seconds – the fall in frequency had already been arrested and was being reversed.
