China Pauses New Battery Storage Plant Approvals
Estimated reading time: 5 minutes · Last updated:
Chinese authorities have temporarily paused approvals for new battery storage factories that have not begun construction and launched a formal review of existing and planned capacity. The move accompanies a staggered consumption-tax plan that levies 2% from 1 September 2026 and rises to 4% from 1 September 2027, with exemptions for new-technology batteries until December 2028. Cailianshe first reported the pause. The tax measures were announced by China’s Ministry of Finance, the General Administration of Customs and the State Taxation Administration and cover a range of battery chemistries and photovoltaic cells.
Key takeaways
- Approval pause: China has paused approvals for new battery storage plants that have not started construction, a development first reported by Reuters.
- Battery consumption tax: Designated batteries face a consumption tax of 2% from 1 September 2026 and 4% from 1 September 2027, announced by three central agencies.
- Photovoltaic cells taxed: Photovoltaic cells will be taxed at 2% from April 2027 and at 4% from April 2028.
- Exemptions: China exempted new-technology batteries, including sodium-ion and solid-state types, from the tax until December 2028.

What Beijing has done and how it landed
China’s central financial and customs authorities have opened a review of the country’s battery storage manufacturing capacity and temporarily halted approvals for any plants that have not yet started construction. The review follows industry reports that new projects are adding to oversupply in batteries for energy storage, mirroring earlier cycles in EV and solar-panel manufacturing.
The policy package combines an administrative pause on project approvals with tax measures aimed at cooling demand for low-margin output. The Ministry of Finance, the General Administration of Customs and the State Taxation Administration announced the consumption-tax timetable: a 2% levy taking effect from 1 September 2026 and rising to 4% on 1 September 2027 for a set of established battery types. Photovoltaic cells were placed on a parallel timetable, with a 2% charge from April 2027 and 4% from April 2028.
Which chemistries are taxed and which are exempt
The agencies specified which products face consumption taxes and which do not. Mercury-free primary batteries, nickel-metal hydride batteries, lithium primary batteries, lithium-ion batteries and all-vanadium redox flow batteries are subject to the 2%/4% timetable. Photovoltaic cells are treated separately on the April 2027–April 2028 schedule.
Beijing explicitly exempted a set of new-technology batteries from the levy until December 2028. The exemption list in the announcement includes sodium-ion batteries, solid-state batteries, fuel cells and advanced photovoltaic technologies such as perovskite, tandem and gallium arsenide cells. That carve-out signals a policy aim to protect higher‑value, next‑generation chemistries while reining in mass‑market production that has driven down prices.
Why regulators moved: overcapacity and industry spillovers
Chinese battery manufacturing expanded rapidly under years of subsidies that also fuelled fast growth in EVs, solar panels and wind installations. That expansion has left parts of the supply chain with excess capacity and prompted price competition that erodes margins across related industries. Several major solar equipment firms have already diversified into battery storage to offset panel market weakness; the pause targets that dynamic by slowing new greenfield plants.
Putting a tax on manufactured batteries and a temporary approval freeze are tools to slow the pace of new entrants and encourage consolidation or capacity idling. The combination reduces the incentive for speculative factory starts while directing support toward emerging battery types identified as strategically important by the exemptions.
What this means for wind projects and the wider storage market
Projects that pair wind farms with battery storage could face slower local supply growth and firmer pricing pressure in China, at least for the taxed categories. Developers that planned on rapid local build‑out of lithium‑ion storage capacity may encounter longer lead times for new Chinese factory output while existing factories are reviewed.
At the same time, the exemption for sodium‑ion and other emerging chemistries through December 2028 creates a policy window for manufacturers and project owners to pivot to next‑generation cells. That could benefit wind-plus-storage configurations that value different performance traits such as low-temperature operation or longer cycle life and are willing to qualify alternative chemistries.
| Product | 2% tax start | 4% tax start | Exempt until |
|---|---|---|---|
| Mercury-free primary; NiMH; lithium primary; lithium-ion; all-vanadium RFB | 1 September 2026 | 1 September 2027 | |
| Photovoltaic cells | April 2027 | 1 April 2028 | |
| Sodium-ion; solid-state; fuel cells; perovskite, tandem, gallium arsenide PV | December 2028 |
Near-term cases for and against the policy
The case for
- Slowing new approvals and taxing mass-market chemistries should relieve downward price pressure and improve margins for surviving manufacturers.
- Exemptions to December 2028 create room for higher‑value, innovation‑led producers to scale without immediate tax costs, supporting commercialisation of next‑generation batteries.
The case against
- A pause on approvals could tighten supply for projects that depend on rapid domestic manufacturing scale-up, pushing developers to import cells or delay deployments.
- If the review and tax regime are enforced unevenly across regions, consolidation might favour incumbent firms and reduce competition, raising longer‑term costs.
What to be careful about
- The government did not publish a complete list of affected projects, so project-level exposure is uncertain until regulators release details.
- An abrupt halt to approvals could cascade through global supply chains if Chinese exports of taxed battery types face new export or production constraints.
- Tax enforcement or local implementation differences across provinces could create regulatory arbitrage and uneven industry impact.
The bottom line
China’s temporary halt to approvals and the linked consumption-tax timetable are explicit attempts to slow capacity growth in low-margin battery manufacturing while protecting advanced chemistries. For project owners and manufacturers, the immediate effect will be a reassessment of procurement and factory plans for taxed categories; for developers willing to adopt exempted chemistries there is a policy window through December 2028. Clarity on which projects are affected and how the review will be implemented will determine whether this becomes a short correction or a structural reset of China’s storage manufacturing footprint.
What to watch
- Watch for the scheduled tax increase to 4% on designated batteries on 1 September 2027.
- Watch for the 2% tax on photovoltaic cells beginning April 2027 and the rise to 4% on 1 April 2028.
- Watch for the end of the exemptions for new-technology batteries in December 2028.
Frequently asked questions
Why did China pause new battery storage plant approvals?
Authorities moved to pause approvals amid mounting evidence of overcapacity in batteries for energy storage, following similar cycles in EV and solar-panel manufacturing; the pause accompanies a review and tax measures announced by the Ministry of Finance, the General Administration of Customs and the State Taxation Administration.
Which batteries will face the consumption tax and when?
Mercury-free primary, nickel-metal hydride, lithium primary, lithium-ion and all-vanadium redox flow batteries face a 2% tax from 1 September 2026 and 4% from 1 September 2027; photovoltaic cells are taxed on a separate timetable beginning April 2027.
Are any batteries exempt from the tax?
Yes. China exempted new-technology batteries—sodium-ion, solid-state, fuel cells and advanced PV types such as perovskite, tandem and gallium arsenide—from the levy until December 2028.
