Global residential storage market to hit 46.1 GWh in 2026

Global residential battery storage additions are forecast to reach 46.1 GWh in 2026, with Europe accounting for 15.4 GWh and Australia emerging as the world's largest single-country market, driven by the Cheaper Home Batteries Program launched in July 2025. Asia and Oceania are closing the gap on Europe. Top suppliers in the first half of 2026 were Fox ESS, Sigenergy, and Deye. Growth in lower-income regions is being driven by frequent blackouts and high electricity prices rather than emissions reduction.

Where this fits

This is a sovereignty and materials story wearing a market-growth headline. Three Chinese manufacturers dominate global residential battery supply. Australia's subsidy-fuelled surge means tens of thousands of homes will install Chinese batteries with Chinese inverters, managed by Chinese software platforms, on a supply chain that runs through Beijing. The Cheaper Home Batteries Program accelerates this dependency at pace. It also highlights the cost side: subsidies work to shift demand, but they transfer the bill to taxpayers and obscure the real, whole-system cost of a grid that leans on weather-dependent storage and requires gas backup when the sun does not shine and the wind does not blow.

What it means

Australia is building energy infrastructure optimised for reliability under frequent outages, not for a wealthy, stable grid. The subsidy programme makes residential batteries artificially attractive compared to firm generation. Meanwhile, the supply chain, manufacturing, software layer, and spare-parts ecosystem are Chinese-owned. A renewables-plus-storage grid with no firm baseload and no domestic control of critical components is a preparedness risk, not a resilience strategy.
