Core Viewpoint - The green electricity direct connection model is becoming an effective solution to address challenges in energy transition, with 11 provinces in China now mandating energy storage configurations for green electricity direct connection projects [4][15][22]. Policy Developments - As of now, 15 provinces have released formal documents or drafts regarding green electricity direct connection, with 11 provinces explicitly requiring energy storage configurations [4][15]. - The core principle established by the National Development and Reform Commission and the National Energy Administration emphasizes enhancing flexibility through reasonable energy storage configurations [4][15]. Common Requirements - All provinces adhere to the "source determined by load" principle, mandating that the annual self-consumption of renewable energy must account for at least 60% of the total available generation, with a target of 35% by 2030 [16][22]. - The policies reflect a combination of common baseline requirements and innovative local adaptations, ensuring projects achieve source-load balance through energy storage [16][22]. Regional Innovations - Different provinces are adopting unique paths; for instance, Zhejiang mandates a minimum energy storage duration of 4 hours and allows energy storage projects equal market trading rights [5][16]. - Inner Mongolia integrates energy storage with green hydrogen and zero-carbon park development, while Shandong and Hubei leverage electricity spot market advantages to allow energy storage participation in peak-valley arbitrage [6][16]. Market Response - The policies from 11 provinces are a precise response to market demands and industry pain points, as global carbon constraints shift from initiatives to hard regulations [17][18]. - The renewable energy installed capacity in China reached 2.22 billion kilowatts by October 2025, increasing pressure on traditional grid consumption [17]. Case Studies - The green electricity direct connection model has shown significant benefits, such as a 15%-20% reduction in production costs for the green aluminum industry in Yunnan, enhancing its competitiveness in international markets [20]. - The first "point-to-point" direct supply data center in Inner Mongolia achieved over 85% green electricity usage, demonstrating the model's effectiveness in reducing carbon emissions [20]. Technological Advancements - The proliferation of various energy storage technologies, such as all-vanadium flow batteries and sodium-ion batteries, is expanding application boundaries and improving economic viability [21][22]. - The global price of energy storage systems is projected to decrease by 31% by 2025, further supporting the economic feasibility of energy storage configurations [21]. Future Outlook - As pilot explorations begin in cities like Beijing and Shanghai, the green electricity direct connection model is expected to see broader implementation across more provinces [23]. - With improvements in electricity market mechanisms and energy storage pricing policies, energy storage will become a standard feature of green electricity direct connection projects, facilitating large-scale deployment [23].
