Renewables company CleanPeak Energy has inked a 15-year agreement to supply Western Sydney International (WSI) Airport with 100% renewable energy, with 30MW/120MWh of battery energy storage on-site as part of the commercial arrangement.

More than 3.8GWh of combined BESS capacity has either cleared or is undergoing federal environmental assessment under Australia’s EPBC Act.

Tech giant Amazon has signed a new power purchase agreement (PPA) to procure energy from IPP European Energy’s 220MWh Winton North solar-plus-storage project in northeast Victoria, Australia.

Zen Energy, a South Australian renewable energy company co-founded by economist Ross Garnaut, has appointed voluntary administrators after its retail business failed to secure a viable buyer.

Australia’s 55 grid-scale BESS generated a combined AU$17.98 million in estimated gross energy and FCAS market revenue during June 2026.

AGL has delivered a solar and battery microgrid described as “one of the largest privately owned non-mining microgrids in Australia”.

State of charge (SOC) is on the face of it a straightforward measurement for batteries and BESS. But in reality, it’s highly complex and under- or over-reporting still happens in the industry, leading to under-performance and losses in revenue.

Singapore-headquartered clean energy developer Vena Energy has raised AU$1.4 billion (US$970 million) in green finance to support 614MW of solar PV capacity and 1,141MWh of battery energy storage systems (BESS) in Australia.

In 2025, BESS installations surpassed 320GWh, a y-o-y increase of over 50%. While this tells one-side of the story, the growth in cell and system shipments tells an even more significant one, writes Benchmark’s Iola Hughes.

The rising costs of coal and gas mean that the adoption of renewable energy is a “survival issue” for countries in Southeast Asia, and energy storage is critical to the transition.
