重庆：鼓励投资主体探索分布式光伏多元化应用场景建设

Core Viewpoint - Chongqing is encouraging investment entities to explore diversified application scenarios for distributed photovoltaic (PV) construction through the draft implementation guidelines for distributed PV development and construction management [1] Summary by Relevant Sections - Policy Framework: The draft guidelines specify that general commercial and industrial distributed PV projects using self-generated surplus electricity for grid connection should determine different grid connection electricity ratios based on local power load distribution [1] - Electricity Usage Ratios: For projects located within the main urban area of Chongqing, the annual self-generated electricity usage ratio should not be less than 20% across 22 districts and counties. In other districts, the ratio should not be less than 40% [1] - Encouragement of Innovation: Investment entities are encouraged to explore diversified application scenarios for distributed PV, supporting the development of incremental distribution networks, virtual power plants, smart microgrids, and mechanisms for benefit coordination and sharing between large grids and local networks [1] - Integrated Development: The guidelines promote integrated development of source, grid, load, and storage, and encourage research into energy integration, PV + storage, and development models such as PV + 5G base stations [1]
