Two years after Tesla Inc. installed it, the world’s biggest lithium-ion battery is helping to avert blackouts and lower costs as Australian grids struggle to handle surging renewable power generation.

The Neoen SA-owned Hornsdale Power Reserve has responded to three major system outages, helping to restore stability to the network and lower the costs of running the grid, engineering consultant Aurecon Group said Friday. The battery started in 2017 after Elon Musk famously won a bet that he could get a 100-megawatt system up and running in 100 days to help solve a power crisis in South Australia.
