Core Viewpoint - The recent notice from the National Development and Reform Commission and the National Energy Administration marks a shift from planned consumption to market-driven pricing for renewable energy, emphasizing a dynamic pricing coupling mechanism between "renewable energy + nearby load" [1][5]. Group 1: Policy Implementation - The notice sets a quantifiable threshold for self-consumption of renewable energy projects, requiring at least 60% of annual self-generated electricity to be used on-site and at least 30% of total electricity consumption, with a minimum of 35% for new projects starting in 2030 [1][4]. - The policy introduces technical requirements for metering and comprehensive monitoring, addressing long-standing issues of unclear consumption responsibilities and weak data supervision [2][3]. Group 2: Market Dynamics - The new policy compels renewable energy developers to optimize generation curves and storage configurations, enhancing local green electricity utilization and alleviating grid pressure [3][6]. - It establishes a clear service scope and pricing for public grids regarding nearby consumption projects, guiding power generation companies to optimize capacity allocation and reduce investment costs [3][4]. Group 3: Economic Implications - The policy's pricing mechanism exceeds market expectations by including reductions in system operation fees and cross-subsidies for self-consumed electricity, which may lower transmission and distribution costs for high-utilization projects [5][9]. - The transition to a market-oriented pricing mechanism signifies a systemic restructuring, moving towards efficient utilization and value creation in renewable energy development [5][6]. Group 4: Technological Advancements - The upgrade of metering systems is crucial for the effective implementation of integrated renewable energy projects, shifting from macro-level statistics to micro-level real-time monitoring [8][9]. - The new metering approach aims to provide precise insights into energy flows, enhancing the grid's ability to manage distributed renewable energy and demand-side responses [8][9]. Group 5: Future Development - The policy encourages the establishment of micro, autonomous power balance units, promoting localized energy generation and consumption systems that reduce reliance on the main grid [7][9]. - Renewable energy companies are expected to adjust their project development strategies, focusing on areas with stable and high electricity demand that align with renewable generation patterns [9].
