AEMO has set out a storage requirement of almost 50GW in its latest 2026 Integrated System Plan (ISP), split between 35GW of short and medium-duration battery storage for daily firming and 5GW of long-duration energy storage (LDES) for seasonal reliability.

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

RWE has received official sign-off from the AEMO and Transgrid to operate Australia’s first 8-hour BESS at full capacity.

BESS in Australia’s NEM more than tripled their daytime-to-evening energy shifting in the first quarter of 2026, according to AEMO.

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

Recurrent Energy Australia has achieved grid connection approval under clause 5.3.4 of the National Electricity Rules from the Australian Energy Market Operator (AEMO) for its Sundown Energy Park.

Australia’s battery energy storage sector faces mounting operational pressures, following the Australian Energy Market Operator (AEMO) issuing its latest direction to AGL’s Torrens Island battery energy storage system (BESS) on 9 March.

Origin Energy’s 300MW/650MWh Mortlake BESS has entered AEMO’s MMS, marking the facility’s transition into its commissioning phase.

RE Development Pty Ltd has submitted a development application for a 250MW/1,000MWh battery energy storage system (BESS) in Baldivis, Western Australia.

Sam Markham of Fluence Australia believes grid-forming BESS are essential to deliver a safe, secure and affordable decarbonised power system.
