A staggering total of 18GW/65GWh of large-scale BESS came online in China last month, accounting for a quarter of the total capacity deployed across the globe in 2025.

Javier Savolainen of Wärtsilä explains how Australia’s battery storage and pumped hydro fleet have been impacted by the current heatwave.

Fresh off the New Year holiday, Chinese energy storage companies have rolled out successive updates on their IPO progress.

“A multi-stream revenue stacking model” made it possible for Pacifico Energy to self-fund a new grid-scale battery storage project in Japan.

A total of around 4.9GW/14GWh of grid-scale BESS entered commercial operations around the world last month, a 29% fall year-on-year owing to an unusually slow month in China.

A Western Australian government initiative to deploy the largest vanadium redox flow battery (VRFB) project outside China is a “pivotal moment,” one technology provider has said.

The US market is expected to be the largest source of revenue and driver of activity for Fluence in 2026, and a second battery cell deal with a domestic supplier is imminent.

The battery storage industry’s race for higher energy density should be put into a site-level perspective, rather than focusing solely on larger cells.

Nearly 70% of the 4.5GW/12.7GWh of grid-scale BESS that came online across the globe last month was in China.

Japan’s NGK Insulators has discontinued its sodium-sulfur (NAS) battery product line, with the exit of its partner, BASF, thought to have led to the final decision.
