State-backed power firm PPC Renewables has launched construction on its a large-scale BESS in Greece, for which Trina Storage will supply the energy storage technology.

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

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.

Two Finland BESS project announcements, with Exilion ordering grid-forming energy storage technology from Merus Power and Nala Renewables ordering units from Sungrow for 2-hour systems.

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.

UK BESS projects totalling nearly 4GWh awarded planning consent in October, there is now nearly 22GWh under construction.

BESS platform Eco Stor has marked the start of construction on a 300MW/700MWh BESS project in Germany, just days after RWE did the same.

TotalEnergies is reportedly considering selling a stake of ‘about 50%’ in a portfolio of BESS projects in Germany it is deploying via Kyon Energy.

As China enters Q4 2025, the capacity utilisation rate of the country’s energy storage battery manufacturing capacity will remain high, a trade body said.
