Energy Storage and the Power Market has learned that, recently, the Zhejiang Provincial Energy Administration issued the “Notice on Conducting Dynamic Adjustments to the 2025 New‑Type Energy Storage Project Construction Plan.”

The notice states that project additions encompass both new projects and capacity‑expansion projects, with the scope of applications covering energy storage projects on both the generation side and the grid side. In principle, the projects shall commence construction by the end of December 2025, with lithium‑battery energy storage projects required to be connected to the grid and commissioned by the end of June 2026.

The adjustment‑down project refers to a proposed cancellation of the construction project, with the project being reclassified as an information‑adjustment project, such as a reduction in installed capacity.

Grid-side energy storage projects: The construction scale shall, in principle, be no less than 50 MW/100 MWh.

Power‑side energy storage projects: Projects that provide frequency regulation in conjunction with thermal power units, with a single‑unit capacity of no less than 18 MW and a guaranteed overall regulation performance coefficient (Kpd) of at least 0.9.

User-side energy storage projects: The Provincial Energy Administration no longer implements annual construction‑plan management for user‑side projects of 5 MW or greater. , subsequently, annual construction planning for each community will be managed on a case-by-case basis. Authorization Community-level energy authorities In accordance with the requirements of the “Zhejiang Province Measures for the Administration of New Energy Storage Projects (Trial)”, strengthen the management of user-side energy storage projects. Prior to the commencement of a user-side energy storage project, it is necessary to… Filed with the local registration authority Case. Prior to processing grid-connection procedures, project registration must be completed on the Zhejiang Province Electrochemical Energy Storage Management Platform. Conduct data governance and transmission testing independently or via an aggregation platform, and upload operational data after actual grid connection.
