China Battery Storage Use Surges After Policy Shift, Ember Says

China's battery storage utilisation has more than doubled since 2022 following policy shifts toward market-driven mechanisms, with standalone systems averaging 299 charge-discharge cycles annually in 2025 versus 145 in 2022. China just proved that battery storage makes money when operators choose where to build it, not regulators. If you're selling batteries, thermal management, software, or grid integration tech into Asia, your addressable market just expanded—China's now bidding storage capacity against competing uses of capital instead of treating it as a mandate tax.
