China pauses approvals for new battery storage factories

China, the world's largest manufacturer of batteries for energy storage, has temporarily suspended approvals for new factory projects as authorities review existing and planned production capacity amid mounting overcapacity concerns, Reuters reported on Sunday, citing Chinese financial news outlet Cailianshe.reuters

The pause targets new factories dedicated to battery cell production. Projects that have not yet broken ground are frozen, while those already under construction are allowed to continue. The policy could be adjusted later depending on market conditions, according to the Cailianshe report.firstpost+1

Overcapacity Pressures Build

The move reflects growing strain across China's battery storage sector. New energy storage capacity commissioned in the first half of 2026 fell 18% compared with the same period a year earlier, according to Crypto Briefing. Mandatory co-location rules that once required renewable energy projects to pair with on-site storage were relaxed, removing a source of guaranteed demand for battery installations.cryptobriefing

At the same time, solar manufacturers have expanded into the storage space, intensifying competition as prices were already declining. The problems mirror those seen in other Chinese industries, including solar panels and electric vehicles, where rapid investment has led to intense price wars and pressure on profit margins.firstpost

A Broader Regulatory Push

The approval freeze did not arrive in isolation. On September 1, China reinstated a consumption tax of 2% on lithium-ion batteries, with the rate scheduled to climb to 4% by September 2027. Beijing has run similar playbooks across other sectors experiencing overcapacity, including steel, solar panels, and electric vehicles.cryptobriefing

The pause gives authorities time to assess whether planned energy storage investments match expected demand rather than allowing production capacity to expand unchecked. The underlying demand outlook for energy storage remains strong, driven by the growth of renewable power generation and the need for grid flexibility.firstpost

Global Supply Implications

For global energy markets, any sustained tightening of new battery manufacturing capacity in China could eventually affect the supply outlook for energy storage systems, though the immediate impact is expected to be limited because projects already under construction can continue. For manufacturers that had not yet secured approval before the pause, the wait is now indefinite.cryptobriefing+1
