The US development arm of Milan, Italy-headquartered developer Nadara has encountered a setback in its pursuit of a 200MW hybrid BESS destined for Arizona.

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

On 4 September, US Immigration and Customs Enforcement (ICE), along with multiple other law enforcement organisations, raided Hyundai Motor and LG Energy Solution’s electric vehicle (EV) battery cell plant in Ellabell, Georgia, US.

Developer Acciona Energia will add a gigawatt-hour-scale battery energy storage system (BESS) at an existing solar PV plant in Chile.

The three-year rolling partnership, whereby CATL will supply HyperStrong with cells and system products, could be updated annually.

Statkraft, Kyon Energy and Juniz Energy have progressed BESS projects in Germany, all in all totalling a combined 213MWh of capacity.

Octopus Australia has achieved financial close on a AU$900 million (US$587 million) DC-coupled hybrid facility that combines 300MW of solar generation with a 243MW/486MWh battery energy storage system (BESS) in New South Wales.

India’s Adani Group has made its first entry into the battery storage market, announcing a ‘flagship deployment’ that will be the country’s largest project so far when completed.

Energy storage developer and system integrator Energy Vault has released its Q3 2025 financial results, showing growth credited to expanding projects in Australia and its ‘Asset Vault’ subsidiary.

Although vertically integrated ESS-cell suppliers retain more control over their supply chain, system integrators’ flexibility may help them in the medium-term, writes Solar Media Market Research analyst Charlotte Gisbourne.
