The China Energy Storage Alliance (CNESA) of energy industry players has released its Energy Storage data for 2024. Total energy storage installed was 137.9GW, which it said was up 59.9% year-on-year.
Energy storage installed from non-hydro sources, which was 78.3GW, surpassed pumped hydro storage for the first time, the report claims. In 2024, 58.5GW of pumped hydro storage was installed.
China’s newly installed capacity of non-hydro energy storage was 43.7GW for the year, which is claimed to have doubled year-on-year.
December was the month with the largest installations, totalling 13.0GW, it said.
Projects with capacity to store energy of 2–4 hours’ duration were among the most installed, but projects with a duration of 4+ hours came second. This has grown by 45% year-on-year.
Of projects currently under operation, 64% have the capacity for 10MW or less. But for planned or under-construction capacity, it is 100–500MW, it said.
More than 180 projects with a scale of 100MW capacity became operational in 2024, the alliance said.
For all top 10 provinces, the installed capacity exceeded 1GWh. The provinces ranked first in energy scale and power scale were Xinjiang and Jiangsu, it said.
Battery companies secured overseas orders of over 100GWh. For photovoltaic and energy storage companies, this was over 30GWh in 2024.
These orders included:
- battery cells
- battery cabins
- power conversion systems
- energy storage systems
- and EPC, etc.
The report said China installed mega-orders totalling 150GWh for global projects, according to incomplete data.
