告别"单腿走路" 分布式储能盈利模式向多元化演进

Core Insights - The distributed energy storage sector is expected to enter a golden development period by 2025, with cumulative installed capacity in China increasing over fivefold from 570 MW in 2019 to 3,638 MW by the third quarter of 2025 [1] - The growth is driven by declining costs, extensive development of distributed energy, and supportive policies, although challenges such as limited application scenarios and immature business models remain [1][4] Group 1: Market Trends and Applications - Distributed energy storage systems are small-scale systems located on the user side, such as homes and factories, and are crucial for addressing the challenges of renewable energy consumption [2] - The six major application scenarios for distributed energy storage include industrial and commercial storage, distributed photovoltaic storage, green electricity direct connection, area storage, virtual power plants, and charging stations [2] - As of September 2025, industrial and commercial storage accounts for 68.7% of the cumulative installed capacity in China, making it the most mature application scenario [2] Group 2: Green Electricity Direct Connection - Green electricity direct connection projects, which supply renewable energy directly to users without going through the public grid, are a significant application of distributed energy storage [3] - Over 50 green electricity direct connection projects have been approved across more than 20 provinces, enhancing renewable energy consumption efficiency and reducing electricity costs [3] - These projects can be categorized into grid-connected and off-grid types, with distributed energy storage playing roles in reducing waste and ensuring power supply [3] Group 3: Business Model Challenges - The business model for distributed energy storage is still in the exploratory phase, facing challenges such as insufficient policy continuity, limited revenue sources, and inadequate safety standards [4] - Current revenue sources primarily include peak-valley price arbitrage, capacity fee savings, demand response, and participation in electricity markets, with significant reliance on peak-valley price differences [4] - Changes in pricing policies can drastically affect the economic viability of distributed energy storage, particularly in regions with low price differentials [4] Group 4: Policy and Technological Support - The future of distributed energy storage's business model hinges on policy and technological advancements, with expectations for clearer market mechanisms and continued cost reductions [5] - Recent policies from the National Development and Reform Commission aim to regulate electricity market transactions and support the development of distributed energy storage [5] - By the end of 2025, various local policies will further promote the commercial operation of distributed energy storage [5] Group 5: Evolving Profit Models - The profitability of distributed energy storage is shifting from a single price arbitrage model to a more interactive model involving market transactions and auxiliary services [6] - The industry anticipates that with improvements in technology and safety, distributed energy storage will see widespread application during the 14th Five-Year Plan period [6] - Recommendations for enhancing profitability include diversifying revenue sources and leveraging market mechanisms effectively [7] Group 6: Future Outlook - The industry believes that the simplistic models based solely on peak-valley price arbitrage will be replaced by more sophisticated models that reflect the true value of energy [8]
