输配电价形成机制迎重要变革

Core Viewpoint - The recent issuance of four revised pricing methods for transmission and distribution by the National Development and Reform Commission marks a new phase in China's transmission and distribution pricing reform, aimed at establishing a scientific pricing mechanism to support the construction of a unified national electricity market and promote green and low-carbon energy transformation [1] Group 1: Enhancing Grid Infrastructure - The revised methods introduce an innovative capacity mechanism that allows for the exploration of two-part or single capacity pricing for cross-provincial and cross-regional projects primarily transmitting clean energy, ensuring fixed cost recovery and improving channel utilization efficiency [2] - The methods clarify the cost boundaries for pricing, excluding costs from pumped storage and new energy storage stations, while including environmental protection and water resource taxes, thereby optimizing the cost structure and highlighting the ecological value of the grid [2] Group 2: Incentivizing Grid Efficiency - The methods continue the incentive mechanism where 30% of the revenue from actual utilization hours exceeding the approved hours is shared with grid companies, promoting efficiency and supporting key areas like peak-shaving capacity and transmission channel optimization [3] Group 3: Supporting National Electricity Market Development - The methods establish a unified pricing system that ensures transparency and rationality from the cost source, clarifies the functions and pricing of various grid levels, and synchronizes adjustments over time, which is crucial for advancing the national unified electricity market [4] - The methods address rigid pricing mechanisms for cross-provincial transmission by enhancing flexibility in pricing for clean energy projects, thereby improving regional power regulation and resource allocation [4] Group 4: Promoting Clean Energy Utilization - The proposed two-part or single capacity pricing for clean energy transmission aims to reduce costs and enhance competitiveness in the unified electricity market, supporting large-scale renewable energy base power delivery [5] - The methods encourage the establishment of a nearby consumption mechanism and explore single capacity pricing for new energy consumption scenarios, fostering innovation in service models and promoting the maturity of distributed energy markets [6] - The continuation and enhancement of the excess revenue sharing mechanism, where 70% of excess revenue from cross-provincial transmission is allocated to support clean energy delivery, incentivizes renewable energy companies to improve efficiency and mitigate curtailment issues [6]
