The Provincial Energy Bureau replied that in order to consider the diversification of new energy storage and the combination of short-term and long-term development, the next step is to focus on shared energy storage projects, mainly using all vanadium liquid flow, and develop some compressed air energy storage. In principle, no new lithium iron phosphate shared energy storage projects will be built.

Hello!

You have received your message in the mailbox of our bureau director. After careful research, the response is as follows:

As of the end of June 2025, the province has put into operation 4.987 million kilowatts of grid connected new energy storage, with all technical routes being lithium iron phosphate. Among them, there are 24 centralized shared energy storage projects with an installed capacity of 4.555 million kilowatts. There are 11 centralized shared energy storage projects under construction, with an installed capacity of 2.3 million kilowatts, and all technical routes are lithium iron phosphate. In order to consider the diversification of new energy storage and the combination of short-term and long-term development, the next step is to focus on shared energy storage projects, mainly using vanadium liquid flow, and developing some compressed air energy storage. In principle, no new lithium iron phosphate shared energy storage projects will be built. But there are no restrictions on other energy storage projects, such as source side distribution storage and user side distribution storage, which can continue to use the lithium iron phosphate technology route.

Thank you for your concern and support for energy work.
