China’s battery industry is entering a new phase of expansion, driven not by electric vehicles alone but by a convergence of domestic power market reforms and an unprecedented global buildout of data centres. What once appeared to be a supplementary segment of the clean-energy transition—battery energy storage—is rapidly becoming a core pillar of modern electricity systems. At the heart of this shift is China, where regulatory change has transformed storage economics at home just as international demand has surged abroad.
The result is a battery boom that is reshaping global supply chains. Chinese manufacturers, already dominant in lithium-ion cell production, are scaling up output at a pace that few competitors can match. Energy storage, long overshadowed by electric vehicles, is now emerging as a strategic growth engine that links China’s power reforms with the world’s appetite for artificial intelligence, renewables and grid resilience.
Power Market Reform Unlocks Storage Economics
For years, China built battery storage capacity at scale, largely through administrative mandates that required renewable energy developers to pair wind and solar projects with storage. While this policy rapidly expanded installed capacity, it left a fundamental problem unresolved: profitability. Storage assets were often underutilised because fixed electricity prices offered little incentive to charge and discharge batteries in response to grid conditions.
That dynamic began to change with a sweeping reform of China’s electricity market. New rules introduced this year require many newly built power projects to sell electricity through market-based auctions rather than fixed tariffs. This shift has injected price volatility into the system—precisely the condition under which energy storage thrives.
Batteries can now arbitrage price differences, charging when electricity is abundant and cheap, and discharging during peak demand when prices spike. Early data show storage plants running longer and more frequently, signalling that utilisation rates are rising as the market begins to reward flexibility. In effect, reform has turned batteries from idle compliance assets into revenue-generating infrastructure.
This change is structural rather than cyclical. As more renewable capacity enters the grid, price swings are likely to widen, further strengthening the business case for storage. For battery manufacturers, that translates into sustained domestic demand rather than policy-driven stop-start cycles.
AI Data Centres Create a New Class of Power Demand
While reforms are unlocking demand inside China, the global driver of the battery boom lies in the rapid expansion of data centres, particularly those supporting artificial intelligence. AI workloads require enormous amounts of electricity, delivered with high reliability. Traditional baseload power—gas, coal or nuclear—cannot scale quickly enough in many regions, creating a bottleneck that storage paired with renewables is increasingly filling.
In markets such as the United States and parts of Europe, solar-plus-storage is becoming the fastest deployable solution for new data-centre power needs. Batteries smooth intermittent generation and provide backup during grid disturbances, making them essential to data-centre design rather than an optional add-on.
This shift has globalised demand for energy storage at a speed few anticipated. Forecasts for battery-energy storage installations have been repeatedly revised upward, reflecting how rapidly AI has changed power planning assumptions. Even where utilities are cautious, hyperscale technology firms are pushing ahead with private power solutions that rely heavily on storage.
China’s Manufacturing Edge Becomes Decisive
The surge in demand has exposed a stark imbalance in global supply. While companies like Tesla lead in integrated energy storage systems, the vast majority of lithium-ion cells inside those systems are produced in China. Manufacturing scale, supply-chain integration and cost control give Chinese firms a decisive advantage.
All leading global suppliers of energy-storage cells are Chinese, including CATL, BYD and EVE Energy. These companies built capacity initially to serve electric vehicles, but are now repurposing and expanding production lines for stationary storage.
Energy storage differs from automotive batteries in performance requirements and margins, but it benefits from similar economies of scale. Chinese manufacturers can leverage existing supply networks for lithium, cathodes and anodes, enabling rapid expansion without the bottlenecks facing newer entrants elsewhere.
Exports Rise as Storage Goes Global
China’s battery exports have surged, with energy storage now a major contributor alongside electric vehicles. Storage systems are being shipped to Europe to stabilise ageing grids, to the Middle East to support massive renewable projects, and to emerging markets seeking to leapfrog traditional power infrastructure.
Europe’s energy transition has been particularly supportive. High renewable penetration has increased grid volatility, while geopolitical shocks have underscored the value of domestic resilience. Batteries offer a relatively quick fix, and Chinese suppliers have been able to deliver at scale and speed.
At the same time, Chinese firms are capitalising on overseas renewable projects built by Chinese contractors, particularly in the Middle East and parts of Asia. Storage has become an integral component of these projects, embedding Chinese battery technology into global infrastructure.
Policy Support Reinforces the Domestic Base
China’s central and provincial governments have doubled down on storage as a strategic priority. A multi-year plan aims to nearly double battery storage capacity within a few years, complemented by new provincial-level incentives. These include capacity payments—fees paid simply for keeping storage available—which provide predictable revenue streams and further improve project economics.
Such mechanisms mirror capacity markets in mature power systems, signalling that China is institutionalising storage as a core grid asset rather than a temporary policy experiment. For manufacturers, this creates visibility that justifies continued investment in factories, research and supply chains.
The effect is cumulative. Domestic demand absorbs output, policy stabilises revenue expectations, and exports capture global growth. Few other clean-energy sectors enjoy such aligned tailwinds.
Despite the momentum, risks remain. The United States has tightened restrictions on clean-energy projects that use components from designated “foreign entities of concern,” a category that includes China. These rules could limit the direct participation of Chinese firms in subsidised U.S. storage projects, forcing them to adapt through joint ventures, licensing or offshore manufacturing.
However, these barriers have not fundamentally altered the global balance. Even where Chinese brands are excluded, non-Chinese system integrators often rely on Chinese cells, reflecting the lack of alternative supply at scale. Over time, diversification may increase, but near-term dependence remains high.
Geopolitical scrutiny also adds uncertainty, particularly as storage becomes more strategically important for national grids. Yet the same importance makes rapid substitution difficult, giving Chinese manufacturers leverage despite political headwinds.
Why This Battery Boom Is Different
Previous cycles in China’s battery sector were driven by subsidies or single end-markets, notably electric vehicles. The current boom is broader and more durable. It rests on three reinforcing pillars: domestic power market reform, global data-centre demand, and entrenched manufacturing dominance.
Crucially, the reform of electricity pricing has aligned economic incentives with physical needs. Batteries are no longer built simply to satisfy regulations; they are built because they make money in a market that values flexibility. At the same time, AI and renewables are rewriting power demand globally, ensuring that storage growth is not confined to one country or policy regime.
As a result, energy storage is moving from the margins of the energy transition to its core. China’s power reforms have unlocked domestic demand, while global digitalisation has pulled Chinese batteries into grids worldwide. Together, they are ushering in a battery boom that looks set to define the next phase of the clean-energy economy.
