Scale of Energy Storage Deployment in China
- China’s installed new energy storage capacity surged to approximately 74 GW/168 GWh by the end of 2024, marking over a 130% year-on-year increase and a twentyfold rise since 2021.
- By September 2024, the cumulative operational energy storage capacity reached 111.49 GW, including pumped hydro and non-hydro storage, with non-hydro storage surpassing 50 GW for the first time.
- Large-scale projects dominate the landscape, with systems over 100 MW accounting for 62.3% of capacity—an increase of 10% compared to 2023.
Impact on Global Costs
Economies of Scale
- The massive scale and rapid deployment foster manufacturing economies of scale. With high volume production of battery cells, storage systems, and related components, unit costs decrease substantially.
- Larger projects (100 MW+) allow optimized deployment of infrastructure, reducing per-unit installation and operational costs compared to smaller projects, reflecting a mature and cost-efficient supply chain in China.
Technology Advancement and Cost Reduction
- China’s dominant market scale encourages innovation and competition, which lowers technology and system costs globally.
- Increased full-load equivalent hours (about 1,000 hours per year on average) enhance system value and financial viability, pushing manufacturers to produce more cost-effective and durable storage technologies.
Market Leadership and Export Influence
- China’s leadership in battery manufacturing and energy storage systems means global markets benefit from Chinese economies of scale and price competition.
- As Chinese companies scale production and export technologies worldwide, global energy storage system prices trend downward, making storage projects more affordable internationally.
Grid Support and Renewable Integration
- Large-scale storage supports renewable energy integration and grid stability more efficiently, reducing the need for expensive fossil fuel peaker plants and enhancing the overall economics of renewable energy. This indirectly drives down the global cost of clean energy systems.
Summary
China’s rapid expansion and concentration of large-scale energy storage projects significantly drive down costs through economies of scale, innovation stimulation, and competitive manufacturing. This scale not only benefits the national grid integration but also exerts downward pressure on global energy storage costs by setting benchmarks for price and technology.
