China's battery storage prices rise as exports jump 83%
Nikita LutsenkoFounder & CEO, SOLTECH
China commissioned 21.81 GW / 58.60 GWh of storage in H1 2026, its first half-year decline, while system prices rose and overseas orders hit 298 GWh.
China's new battery storage deployments fell for the first time on record in the first half of 2026, while system prices rose and exports surged. CNESA data presented at the 11th Western Energy Storage Forum shows 21.81 GW / 58.60 GWh commissioned in H1 2026, down 18% and 16% year on year. Overseas contracts reached 298 GWh, up 83%, with the Middle East named a fast-growing market.

Fewer projects, bigger projects, longer duration
The decline in new capacity is not a collapse in appetite. The number of newly commissioned projects fell 51% year on year while capacity fell only 18%, which means the surviving projects are far larger. The share of projects sized at 100 MW or above rose by 8 percentage points.
Duration moved the same way. The average storage duration of newly commissioned projects reached 2.69 hours, up 2.3% year on year, and the share of projects at four hours or more rose 4.8 points. CNESA chairman Chen Haisheng framed the shift as a move away from pure volume growth toward optimising individual plant scale and duration.
Standalone storage - batteries built as merchant assets rather than bolted onto a solar or wind plant - accounted for 15.1 GW, or 69.3% of all new capacity, up 13.9 points year on year. That followed National Document No. 114, which established China's first national capacity pricing mechanism for standalone storage. Provinces including Gansu, Jilin, Shaanxi, Xinjiang, Hubei, Ningxia and Qinghai have since issued implementation rules, giving standalone assets a three-part revenue model: capacity tariffs, energy market trading and ancillary services.
Why prices rose while deployments fell
The pricing move is the part that should interest anyone buying batteries anywhere. Average winning prices for storage systems in Chinese centralised procurement rose across the board: RMB 599.3/kWh for two-hour systems, up 8.3% year on year, and RMB 541.3/kWh for four-hour systems, up 21.1%.
Three forces pushed the same way. Procurement volumes surged - centralised and framework volumes hit 80.16 GWh, up 95%, and awarded EPC capacity reached 161.2 GWh, up 112%. Cell capacity expansion moderated, with domestic operational capacity at 809.5 GWh against global shipments of 380 GWh in the half. And AI data centres emerged as a new structural demand source, pulling high-rate cells and backup power systems into a market that previously served grids and renewables.
CNESA describes the competitive basis as shifting from pure price bidding toward comprehensive capabilities - project development, trading strategy and full-lifecycle O&M. Spot-market peak-to-valley spreads have narrowed and charging costs have risen, so a cheap system that is operated badly no longer clears.
Where the 298 GWh of exports is going
Chinese storage firms signed 298 GWh in overseas contracts in H1 2026, an 83% year-on-year rise. Europe remains the core market. CNESA names the Middle East, India and Chile as the fast-growing regions.
The nature of the business changed alongside the volume. CNESA describes a shift from equipment export toward overseas manufacturing bases, local O&M provision, technical partnerships and end-to-end turnkey delivery. It also names the constraints plainly: trade barriers, supply chain security and local regulatory compliance.
The SOLTECH view
Read together, these numbers say something uncomfortable for anyone planning a Gulf battery project on a 2027 or 2028 timeline: the cheap-and-getting-cheaper era has paused, and the Middle East has just become one of the regions competing for the same cells.
- For a villa owner in the UAE: this does not change our answer on residential batteries in Dubai, which remains no for most households. Under DEWA net metering your surplus is already banked against your bill, so a battery buys you backup rather than savings, and it has to earn its cost against a tariff that is not high enough to justify it. Rising cell prices make that arithmetic worse, not better. If you want the reasoning in full, see how a DEWA-connected system actually works.
- For a warehouse, hotel or factory operator: this is directly relevant if storage is anywhere in your plan. The 21.1% year-on-year rise in four-hour system pricing is the number to sit with, because four-hour is the duration a C&I peak-shaving system typically wants. We would ask suppliers for firm pricing with a defined validity window rather than an indicative figure, and we would not assume a quote from six months ago still stands.
- For an investor or EPC: two consequences. First, the base case for battery capex in a Gulf model should now be flat to rising, with declines treated as upside - the opposite of how most 2024-vintage models were built. Second, 580 winning EPC bidders in China, up 88%, means the contractor pool supplying this equipment has broadened enormously, and broad pools contain weak members. Bankability screening on storage suppliers matters more in 2027 than it did in 2025. Our framing for project risk and returns covers where we put these assumptions.
Where we would be careful: this is CNESA's own dataset, described as preliminary, and it measures Chinese domestic procurement. A rising RMB-denominated winning price in a Chinese centralised tender does not translate one-to-one into a delivered price in Jebel Ali, where freight, duties, warranty terms and currency all intervene. We would also flag what is missing - CNESA reports contract volumes for overseas orders, not prices, so we cannot say from this data whether export pricing followed domestic pricing upward. Until an export price series appears, the honest position is that the domestic signal is clear, the export signal is inferred, and a buyer should verify with a live quote rather than an index. What we will not do is repeat the line that batteries get cheaper every year. For the first half of 2026, in the world's largest market, they did not.
