The economics of energy storage are changing as China’s power sector evolves, at a time when the world’s need for dependable, flexible electricity is growing. By moving energy pricing toward market-based pricing, China’s electricity market revamp has opened new revenue opportunities for battery storage operators while also stimulating a manufacturing boom among Chinese enterprises that already control the majority of the world’s supply. China’s energy storage ecosystem is becoming a key component of the global clean-energy transition as data centers proliferate, renewable energy grows, and grids suffer under increased loads.

Going Global: Manufacturing Boom Meets Surging Demand

Artificial intelligence data centers, renewable energy integration, and the need for grid stability in both developed and emerging economies are driving a sharp increase in global energy storage demand. By boosting domestic demand that promotes scale, cost reductions, and export competitiveness, China’s electricity market revamp is strengthening this momentum.

The following are major causes of the worldwide surge:

• Explosive growth in shipments: Global shipments of lithium-ion battery cells for energy storage are expected to increase by 75% year over year, thanks to Chinese producers.
• Export dominance: Batteries are China’s most valuable clean-tech export since 2022, with over $65 billion worth of storage and EV batteries shipped this year.
• Industry concentration: Supply-chain leadership is highlighted by the fact that all six of the world’s leading battery cell suppliers—CATL, HiTHIUM, EVE Energy, BYD, CALB, and REPT BATTERO are Chinese.
• Growing worldwide investment: UBS has increased its 2026 installation prediction by 25%, while the International Energy Agency predicts that global battery storage investment will exceed $66 billion this year.

The company’s performance shows this increase. While REPT BATTERO announced record battery shipments in the third quarter, EVE Energy recorded a 35.5% increase in energy storage sales volumes over the first three quarters. According to analysts, the fact that companies are working double shifts to fulfill orders reflects the rapid increase in demand.

Power Market Shake-Up: From Idle Assets to Profitable Storage

At home, China’s electricity market revamp is transforming how battery storage earns money. Due to set power pricing that restricted arbitrage opportunities, a large portion of China’s enormous battery capacity—roughly 40% of the world’s total was historically underutilized. By mandating that new projects sell power through competitive market auctions, the June reforms altered that dynamic.

How the reforms are improving storage economics:

• Price arbitrage enabled: Batteries can now be charged during periods of low electricity costs and discharged during periods of high electricity prices, thanks to price arbitrage.
• Increased utilization: In the third quarter, storage plants’ average daily operational time increased to 3.08 hours, a significant increase over the same period last year.
• Policy support: In addition to new provincial subsidies and capacity tariffs in 10 provinces, a $35 billion national plan aims to almost triple battery storage by 2027.
• Structural shift: A transition toward more adaptable, modular technologies is indicated by the fact that battery storage capacity has surpassed pumped hydro.

These adjustments coincide with China’s battery exports, which include EV and storage applications, hitting a record $66.76 billion in the first ten months of this year. Up to 800 gigawatt-hours of energy storage cells will be shipped worldwide in 2019, according to consultancy Infolink, representing a 43% increase.

China’s energy storage industry is at the center of the changing power landscape, driven by the interaction between domestic reforms and foreign demand as global grids modernize and digital infrastructure grows.
