Final tests for big battery

FINAL testing is under way on South Australia’s big battery after work to increase its capacity by 50 per cent to 150 megawatts.

Energy Minister Dan van Holst Pellekaan said the project was entering its critical testing phase by activating the battery’s full capacity.

“The increase in storage power and capacity means a faster response to disturbances such as network faults, so that within milliseconds the Hornsdale Power Reserve can help stabilise the grid,” he said.
