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.

Wärtsilä has brought the 150MW/300MWh Bungama BESS online in South Australia, for owner and operator Revera Energy.

Samsung C&T Renewable Energy Australia has submitted the 600MWh Comet Park BESS for federal environmental assessment under the EPBC Act.

Australian AI infrastructure developer Firmus Technologies has signed a 12-year wholesale energy supply agreement with Gunvor Group, including 1.5GWh of battery storage by 2032.

On 29 June, the China Energy Storage Alliance (CNESA) and the China Automotive Battery Industry Innovation Alliance jointly released the ‘Initiative on Standardising Supplier Payment Practices for Power and Stationary Storage Battery Enterprises.’

Energy North has submitted a proposed 1GW hyperscale data centre campus with a co-located 16GWh BESS to Australia’s EPBC Act.

French independent power producer (IPP) Neoen Australia has begun construction of a 215MW/963MWh battery energy storage system (BESS) at its 440MWp Culcairn Solar Farm in New South Wales, Australia.
