French renewable energy developer Neoen has applied to develop a huge $3 billion Goyder South wind, solar and energy storage project— including a proposed large battery that's nearly 10 times larger than an expanded “Tesla big battery” at Hornsdale.
The plan proposes a total of 1,200MW of wind energy, 600MW of solar PV, and 900MW/1800MWh of battery storage, reported Renew Economy. Each stage would be delivered in three equal tranches of 400MW wind, 200MW solar and 300MW/600MWh of battery storage. Combined, they would generate around 4.8 terawatt-hours of zero-emissions power each year, nearly doubling the current output of wind and solar in the state, and taking South Australia close to the Liberal government’s net 100% renewables target just on its own.
Neoen says the wind facility will consist of up to 163 turbines, suggesting a capacity of 7.3MW per turbine - by far the largest announced in Australia to date.
The solar farm would be spread across 3,000 hectares. Lithium-ion batteries would deliver 900MW with two hours of storage. And associated infrastructure for connection to the electricity grid would include three substations, access tracks, underground connection cabling and transmission lines.
Neoen says the “extremely large battery” associated with the proposed project would be located on the South Australia end of the future EnergyConnect line and would, like the Hornsdale Power Reserve, provide crucial grid support functions to the states energy supply.
At the moment, Neoen has not announced which company will be the battery supplier. Nevertheless, the French renewable energy developer already has a fruitful and profitable partnership with Tesla, which is why there is reason to suspect that the Californian company could become the battery supplier.
At the end of July, Neoen said its battery storage revenue in the first six months jumped to € 24.6 million ($40.4 million) from € 8.4 million. The company's revenue comes almost entirely from the Hornsdale Power Reserve -- “Tesla big battery.”
