Overview
The 2026 World Energy Storage Congress opened in Ningde on October 15. Vice Minister of Industry and Information Technology Xiong Jijun said China’s new-type energy storage industry has shifted from scale expansion to a new stage where actual operational benefits are central, calling for balancing development and safety and accelerating the move from scale to innovation leadership. CATL chairman Robin Zeng argued storage is upgrading from a renewable “supporting facility” to “new-type infrastructure” for the power system.
By the numbers, China’s energy-storage battery output exceeded 420 GWh in the first half of 2026, up 110% year on year; cumulative new-type storage capacity surpassed 153 GW (396 GWh) by end-June, a 50-fold increase from the early 14th Five-Year Plan period. MIIT recently issued the “15th Five-Year Plan for the New-Type Battery Industry,” prioritizing power-side, grid-side and industrial-park/data-center applications.
Background & Interpretation
1. Industry Background and Policy Context
With combined wind and solar capacity at roughly 1.95 TW—nearly half of total installed power—renewable output volatility increasingly strains grid stability. New-type storage at 153 GW / 396 GWh has become a vital system regulator. Management focus is shifting from “whether storage is available” to “dispatchable power, duration, available capacity and actual response performance.”
2. Core Drivers and Underlying Mechanism
The upgrade reflects storage’s systemic value: smoothing volatility on the supply side, providing peak-shaving and frequency regulation on the grid side, and enabling demand response on the user side. As storage becomes “infrastructure,” its revenue model shifts from single capacity leasing to a multi-source mix of capacity payments, ancillary services, spot-price arbitrage and green-premium—forcing improvements in technology and operational efficiency.
3. Market Structure and Industry Impact
MIIT stresses preventing “involution-style” competition and improving capacity early-warning, while pushing breakthroughs in long-duration and inherently safe storage. Leaders must build three capabilities: whole-station solutions, underlying innovation and systematic validation. For battery, PCS, EMS and system integrators, the shift from scale to value competition will reshape margins and concentration.
Implications & Outlook
Near term, policy normalization of capacity control and competition order should ease price wars and margin erosion; medium term, long-duration, grid-forming storage and overseas markets will open incremental space under the 15th Plan. Key variables: utilization-hour and available-capacity assessment rules, ancillary/spot-market rollout pace, and commercialization of long-duration routes (Li-ion / flow / compressed air).
Takeaways for Industry Participants
- Storage firms should move from “selling equipment” to “delivering system value,” strengthening integration, validation data and full-lifecycle operation.
- Renewable developers should embed storage into core generation planning, optimizing charge/discharge to raise firm output and absorption.
- Investors must track the revenue shift from capacity leasing to multi-market income, cautiously assessing cash flow and payback.
