A year after Elon Musk rolled out what was then the world's biggest lithium-ion battery to aid South Australia's blackout-prone power grid, more projects are set to follow in its footsteps at home and abroad.

Its success is a boost to other plants commissioned around the world, including a larger one in South Korea.
