China’s Electrochemical Energy Storage Industry 2026: 136 GW Installed, 40x Growth, and the Market Mechanisms Reshaping a World-Leading Industry

Executive Summary

China’s electrochemical energy storage sector has entered a new phase — one defined not by breakneck installation growth alone, but by the maturation of the market mechanisms that determine whether those installations are economically viable. According to the Electrochemical Energy Storage Industry Development Report 2026, published in June 2026 by the China Electricity Council (CEC) Electric Transportation and Energy Storage Branch in collaboration with State Grid New Energy Cloud Technology, HyperStrong, CRRC Times Electric, and Shanghai Tianwei Energy Technology, China’s new-type energy storage installed capacity reached 136 GW / 351 GWh by the end of 2025 — a more than 40-fold increase from the end of the 13th Five-Year Plan period (2020), firmly establishing China as the world’s largest energy storage market.

But the more transformative story lies in the policy architecture that has been erected around this capacity. 2025 witnessed a pivotal shift: the abolition of mandatory storage co-location requirements for renewable energy projects, the establishment of capacity pricing mechanisms that provide stable “base salary” revenue for storage assets, the expansion of electricity spot markets to cover 30 provinces, and the introduction of nationwide capacity remuneration for grid-side storage — a first-of-its-kind policy globally at this scale. Over 800 provincial and local policies were issued in 2025 alone, and more than 20 provinces explicitly named new-type energy storage in their 15th Five-Year Plan proposals.

This article provides a comprehensive synthesis of the report’s data-rich analysis of China’s energy storage policy landscape, market mechanisms, provincial economics, and development trajectory.

Part I: Market Scale — 136 GW and Counting

1.1 The Numbers That Define the Market

1.2 From Scale to Sustainability

The report’s framing of this growth is instructive. It does not celebrate the 40x expansion as an unqualified success. Instead, it characterizes 2025 as the year the industry transitioned from “scale-driven development to comprehensive market-oriented operations.” This transition was triggered by three simultaneous policy shifts:

1. The abolition of mandatory co-location: In February 2025, the NDRC and NEA issued a notice eliminating the requirement that renewable energy projects must pair with storage — a policy that had driven much of the installation boom but often produced underutilized assets
2. The introduction of capacity pricing: A stable revenue floor was established for grid-side storage, shifting the economic model from speculative energy arbitrage to contracted availability payments
3. The completion of the electricity spot market architecture: With 25 spot market operating regions covering 30 provinces by end-2025, storage assets gained access to price signals that reflect real-time system value

2.2 The Three Pillars of Market Reform

The report identifies three interconnected pillars that now govern storage economics:

Pillar 1: Electricity Spot Markets (能量市场)

• 25 operating regions covering 30 provinces by end-2025
• 6 formally operating: Shanxi, Shandong, Gansu, Mengxi (Western Inner Mongolia), Hubei, Zhejiang
• 19 in continuous settlement trial operation
• Only Beijing-Tianjin-Tangshan and Tibet remain uncovered
• Storage participates with dual identity: “charging = power user, discharging = power generator”

Pillar 2: Ancillary Services Markets (辅助服务市场)

• Primary participation: peak shaving and frequency regulation
• Emerging: ramping (Shandong — China’s first), spinning reserve (Shanxi — China’s first), primary frequency regulation, black start (Yunnan)
• Frequency regulation market operates across virtually all provinces, using mileage-based compensation with performance-adjusted pricing

Pillar 3: Capacity Pricing (容量电价)

• January 2026: first national policy incorporating grid-side independent storage into capacity remuneration
• Benchmarked to provincial coal-fired capacity prices, adjusted for storage discharge duration
• Creates a “base salary” (底薪) revenue stream — the most significant structural improvement to storage economics

2.3 The “1+6” Electricity Market Rule System
