European Storage Stocks Rise as China's Battery Export Rebate Heads Towards Its End
EUPD Research says European storage inventories are rising and that oversupply risk is highest in residential and commercial storage in the fourth quarter of 2026 and the first quarter of 2027. The analyst linked it to China's battery export tax rebate, which falls this year and ends on 1 January 2027.
What EUPD said
In an interview with ESS News on 9 October, EUPD Research analyst Ali Arfa said rebate-driven shipments to Europe could push residential and commercial storage prices down towards the end of 2026. Utility-scale prices, he expects, will stay broadly stable, with no significant fall over the next two to three years.
EUPD puts European residential storage installations in 2026 at about 15 to 17 GWh. Arfa also said China's grip on the battery supply chain is unlikely to change much in two years. His estimates of China's share range from about 70 to 95 percent for raw materials and about 80 to 90 percent for battery cells.
The rebate behind it
China's Ministry of Finance and State Taxation Administration announced in January that the VAT export rebate on batteries would drop from 9 percent to 6 percent from 1 April 2026 and be abolished from 1 January 2027. Exporters therefore have a reason to ship before the rebate ends, which is the mechanism EUPD points to for fuller European warehouses.
ESS News also mentions unconfirmed reports that some German wholesalers are selling below manufacturers' direct prices. We could not verify that, and it is a sign of stock pressure rather than proof of lower prices for households.
What households should take from this
An oversupply warning is an analyst's view of the market, not a price forecast for your installer's quote. Installed prices include labour, inverters, certification and margins, and these move more slowly than wholesale stock. We have not seen evidence yet that retail prices have fallen.
If you are timing a purchase, price is only one factor. Our guide to the best time of year to buy and install a home battery covers the practical trade-offs, and our earlier report on EUPD's 57 GWh forecast for Europe shows how fast the market is growing.
