Core Viewpoint - The National Energy Administration has released a draft guideline for evaluating the hosting capacity of distributed energy resources connected to the power system, aimed at enhancing the integration and management of distributed renewable energy sources [1][3]. Summary by Sections General Requirements - The guideline outlines the overall requirements for evaluating the hosting capacity of distributed energy resources, including system-level and equipment-level capacity calculations, result verification, and measures for capacity enhancement [10][15]. System-Level Capacity Calculation - System-level capacity calculations should be conducted annually or according to the design cycle of the power system, considering significant boundary condition changes [16]. - The capacity range for provincial administrative regions or independent control areas is determined through simulation calculations, factoring in new energy utilization rates and flexible adjustment capabilities [16][18]. Equipment-Level Capacity Calculation - Equipment-level capacity calculations should be performed quarterly, focusing on peak output times of distributed energy resources and predicting related parameters such as load and output [17][18]. Capacity Verification - Capacity verification should be conducted at the county level, ensuring that system-level and equipment-level calculations align [20][22]. Open Capacity Assessment and Classification - Open capacity assessments involve evaluating both county-level and transformer-level capacities, following a hierarchical approach [25][28]. - The classification of open capacity levels is based on the availability of space for new distributed energy resources, with specific thresholds for green, yellow, and red alerts [30][34]. Capacity Enhancement Measures - Measures to enhance the hosting capacity of distributed energy resources should ensure the safe and stable operation of the power system, including optimizing new energy utilization and upgrading existing infrastructure [36].

Core Viewpoint - The silicon wafer prices have remained stable this week, with no significant changes in the market despite positive sentiment from recent policy advancements. However, end-user demand has not shown a notable recovery, leading to a stalemate between supply and demand [1][2].

Group 2: Supply and Demand Dynamics - On the supply side, silicon wafer manufacturers are maintaining stable shipping rhythms and have a strong willingness to uphold or increase prices [1]. - On the demand side, the battery and module sectors are exhibiting a cautious attitude due to weak terminal demand, resulting in a subdued transaction atmosphere [1][2]. Group 3: Production Rates - The overall industry operating rate has remained stable, with two leading companies operating at 50% and 46%, while integrated companies are operating between 50% and 80% [1]. - Other companies are also operating within the range of 50% to 80% [1]. Group 4: Future Price Outlook - Looking ahead, some silicon wafer manufacturers have begun to slightly raise prices, with new market quotes indicating G10L at 1.25 yuan/piece, G12R at 1.4 yuan/piece, and G12 at 1.6 yuan/piece. The realization of these prices will depend on the acceptance levels from downstream battery and module sectors [2].
