The $30 million, 30 MW battery will be built at the Dalrymple substation on the Yorke Peninsula, west of Adelaide. A partnership between the Australian Renewable Energy Agency and network provider ElectraNet, it is expected to be operating by late summer, when electricity demand typically peaks.

ARENA will contribute up to $12 million toward the cost of the battery.

South Australia no longer has any coal-fired power, and gets about 40 per cent of its electricity from wind farms. With expensive natural gas-fired plants responsible for much of the recent surge in power bills due to inflated export prices, attention has turned to new, cheaper ways to support variable generation.
