Core Viewpoint - The German Federal Network Agency (BNetzA) is reforming the electricity transmission and distribution pricing framework (AgNes) to address issues arising from the energy transition and to comply with EU regulations, with the final framework expected to be implemented by 2029 [1][2]. Background of the Reform - The reform is a response to a 2021 EU court ruling that mandated independent regulatory bodies to set grid charging standards, ensuring market neutrality and regulatory independence [2]. - The energy transition in Germany has altered the operational logic of the electricity system, necessitating a new regulatory framework to resolve existing conflicts [2]. Current Issues in the Pricing Mechanism - The number of full-paying users is decreasing, leading to rising transmission and distribution prices, as the current mechanism places the entire cost burden on end-users while exempting power sources from grid connection fees [3]. - The influx of distributed solar and wind energy has reduced reliance on high-voltage electricity, distorting the cost-sharing structure and increasing high-voltage prices [4]. - The lack of incentives for flexible electricity usage and the absence of time-based pricing mechanisms hinder demand-side response and the development of flexible resources like energy storage [4]. Key Directions and Points of the Reform - The AgNes framework emphasizes cost orientation, feasibility, financial allocation, and incentive functions as its four basic principles [5]. - A new mechanism for cost-sharing from the generation side is proposed, which includes three options for sharing grid costs, potentially amounting to €16.5 billion annually [6]. - The reform advocates for a shift towards capacity-based pricing, which would more accurately reflect the costs of grid construction and maintenance [7]. - The introduction of dynamic pricing mechanisms is suggested to better manage grid loads and encourage users to adjust their consumption patterns [8]. - The reform aims to unify regional transmission prices to enhance fairness and transparency, while balancing regional equity and dynamic pricing feasibility [8]. Implications for Energy Storage and Distributed Energy - The reform plans to clarify the cost-sharing responsibilities of energy storage facilities, moving away from a full exemption policy to a model where storage pays for both energy and capacity charges [9]. - The proposal includes simplifying voltage levels and introducing bidirectional cost-sharing to better reflect the realities of distributed energy integration [10]. Insights for Other Markets - The AgNes framework offers valuable lessons for improving transmission and distribution pricing mechanisms in other countries, particularly in terms of fair cost-sharing and incentivizing efficient energy use [11]. - Emphasizing capacity and load-based pricing can help address issues of uneven peak loads and high capacity usage among certain users [12]. - The need for a refined cost-sharing mechanism that adapts to changing grid flow patterns is highlighted, suggesting a focus on marginal costs at different network nodes [12].

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]
