Grid-Scale Battery Storage Go In Australia

In an opinion piece published in the Australian Financial Review on Wednesday, Garnaut – who currently chairs integrated community renewables and storage provider ZEN Energy, as well as the recently launched IIG Solar Fund – said the recent South Australian “energy crisis” had highlighted the need for urgent energy market reforms.
In particular, he said, a solution was needed to stabilise the short-term variations in supply frequency and price.
“An immediate answer is grid-scale batteries, which are being deployed in other developed countries to balance increasing volumes of wind and solar energy,” Garnaut wrote.
“Solar power batteries can respond to the need to add or absorb power in less than a second – much more quickly than gas generators,” he said.
“If optimised to maximise value in provision of grid stability services, the battery can store surplus power from excess generation from the midday sun or overnight wind for use in the evening and morning peaks at total costs that are lower than the prices of wholesale hedge contracts, or than exposure to the wholesale market at these times.
Garnet also said that the application of grid-scale solar and solar battery solutions could be of particular benefit to major industrials, to lower total costs of power.
