By the end of December 2025, China’s cumulative installed capacity of new energy storage technologies including lithium-ion reached 144.7GW, representing an 85% year-on-year rise.

China has reached well over 70GW of installed BESS capacity, while DC block prices appear to be ‘stable’, a local metals price agency said.

NEC has now executed five grid-scale battery energy storage projects in China and been awarded another, winning deals in spite of what a company representative described as “aggressive” price competition from domestic vendors.

Energy storage projects were under construction across four provinces of China, amounting to 340.5MW of new capacity during the first half of this year in the country, according to the China Energy Storage Alliance (CNESA).
