China pauses approvals for battery storage manufacturing projects

China has temporarily suspended approvals for new battery storage manufacturing projects, a regulatory move that signals growing unease about runaway capacity growth in one of the country’s most strategically important industries. The pause, reported by Chinese financial outlet Cailianshe on September 7, 2026, targets new factories dedicated to battery cell production specifically.

Projects that have not yet broken ground are frozen in place. Those already under construction are allowed to continue, at least for now.

Too much of a good thing

China is the world’s largest battery manufacturer by a considerable distance.

New energy storage capacity commissioned in the first half of 2026 fell 18% compared to the same period a year earlier. Mandatory co-location rules that once required renewable energy projects to pair with on-site storage were relaxed, removing a significant source of guaranteed demand for battery installations.

At the same time, solar manufacturers have muscled into the storage space, intensifying competition at precisely the moment when prices were already declining.

The approval freeze is designed to give Beijing time to assess the gap between existing operational capacity and what is actually planned or under construction.

A new tax on top of the slowdown

The approval halt did not arrive alone. On September 1, 2026, China reinstated a consumption tax of 2% on lithium-ion batteries. The rate is scheduled to climb to 4% by September 2027.

Demand for batteries tied to grid balancing and backup power applications continues to grow.

What this means for manufacturers, investors, and the global market

For battery manufacturers, the immediate consequence is straightforward: any company that had not yet secured approval for a new facility before September 7 is now waiting indefinitely. Companies with projects already underway are in a relatively better position.

China has been running similar playbooks across other industries experiencing overcapacity. Steel, solar panels, and electric vehicles have all been subject to rounds of regulatory intervention designed to prevent domestic price wars from destroying the industries Beijing spent years building up.
