Australian transmission operator Transgrid has opened a pathway for 900MW of grid-forming inverter-equipped battery storage to contribute to New South Wales’ minimum system strength requirements.

Ark Energy has received approval from AEMO and Transgrid to connect its 3,148MWh Richmond Valley solar-plus-storage site to the NEM.

Sungrow’s BESS and grid-forming power conversion system (PCS) combined established system voltage within 19 seconds during black-start testing at the company’s newly established large-scale, plant-level grid-forming field test base.

Around 74% of battery storage projects in Australia’s NEM pipeline are confirmed to be equipped with grid-forming inverters, says AEMO.
