SA's big Tesla battery goes full discharge (100MW) for first time


South Australia's Tesla battery (Hornsdale Power reserve) readings (RenewEconomy). 

The largest lithium-ion battery in the world to date (100MW/129MWh), a Tesla, was officially switched on Friday 1 December, 2017, in South Australia. Then on Wednesday, December 13, it discharged its maximum capacity of 100MW during a heatwave. The battery is a back-up for the large amount of renewable energy in the state.


The injection of 100MW into the grid from what is known to the market as the Hornsdale Power Reserve, occurred just before midday (NEM-time). It followed some charging overnight and a brief spurt of discharging and charging earlier in the morning. The battery receives electricity from Neoen’s Hornsdale wind farm, near Jamestown in South Australia.
