Australia’s two large lithium-ion storage batteries are getting attention for all the wrong reasons. Hornsdale Power Reserve, a 150-MW battery collocated with a wind farm in South Australia, is being charged in federal court with failing to deliver on promises to respond to grid demands, and of being technically unable to deliver under the terms it was being paid to meet. Proceedings were filed September 22, just before the testing of a second Tesla-manufactured “Big Battery resumed after a two-month delay following a fire in July.
