Core Viewpoint - The "1+6" basic rule system is established as the institutional foundation for the construction of a unified national electricity market in China, addressing the long-standing issues of "conflicting rules" and "inconsistent standards" in the market [2][3][4] Summary by Sections 1. Importance of the "1+6" Basic Rule System - The "1+6" basic rule system serves as the cornerstone and core framework for the unified national electricity market, addressing fundamental issues of market direction and construction [3] - It integrates and standardizes key operational rules across various segments such as medium to long-term trading, spot markets, auxiliary services, market registration, information disclosure, and measurement settlement, effectively resolving previous inconsistencies [3][4] - This system provides foundational regulatory guidance for the planning, design, construction, operation, and supervision of electricity markets at all levels, essential for creating a competitive and open national electricity market [3] 2. Structure of the "1+6" System - The "1" represents the fundamental operational rules, establishing the basic principles and overall framework for the electricity market, defining the responsibilities and boundaries of market participants, core transaction types, and risk prevention mechanisms [5][6] - The "6" consists of supporting rules that govern key market segments and core trading varieties, including medium to long-term trading rules, spot market rules, auxiliary service market rules, market registration rules, information disclosure rules, and measurement settlement rules [5][6] - Together, "1" and "6" form a coherent and structured whole, ensuring comprehensive coverage of all aspects of electricity trading and service provision [6] 3. Dynamic Coordination of Market Segments - The medium to long-term market, spot market, and auxiliary service market are the core pillars of the electricity market system, working together to optimize resource allocation across time and space [7] - The medium to long-term market locks in significant portions of electricity transactions, providing long-term price signals and stability, while the spot market reacts to real-time supply and demand conditions [7][8] - Auxiliary services act as a safety net, ensuring the stable and secure operation of the electricity system, supporting the efficient functioning of the spot market [7] 4. Time and Space Optimization - From a time perspective, medium to long-term contracts transition into the spot market for fine-tuning adjustments as execution approaches, with auxiliary services providing real-time support [8] - From a spatial perspective, spot market node prices reflect supply-demand dynamics and network congestion costs, guiding resource flow between regions [8]

Core Viewpoint - The implementation of the "136 Document" and subsequent policies in Shandong Province aims to promote the marketization of renewable energy pricing and enhance the development of energy storage systems, leading to a transformation in the energy market dynamics and business models for storage [1][3][10]. Group 1: Policy Implementation - Shandong Province has introduced the "Implementation Plan for Market-oriented Reform of Renewable Energy Grid-connected Pricing" following the "136 Document," along with several supporting documents to ensure a smooth transition in the electricity market by 2025 [1]. - The "396 Document" and "278 Document" outline the necessary steps for a stable transition and high-level consumption of renewable energy, respectively [1]. Group 2: Energy Storage Development - The current installed capacity of new energy storage in Shandong Province has reached 9.6 million kilowatts, primarily from grid-side electrochemical storage, which accounts for about 80% [2]. - The revenue model for grid-side independent storage includes income from arbitrage between low charging and high discharging prices, market capacity compensation, and capacity leasing from renewable energy stations, with respective contributions of approximately 33%, 17%, and 50% [2]. Group 3: Impact of Policy Changes on Storage - The "136 Document" does not mandate energy storage configuration for new renewable projects, which may lead to a shift towards independent energy storage systems and a need for new business models [3]. - The revenue for energy storage systems could decrease significantly if new projects lose capacity leasing income, necessitating a transition to power-side and user-side storage [3]. Group 4: Technological and Market Advancements - Technological advancements have led to a 55% reduction in investment costs for lithium batteries compared to 2021, enhancing energy storage capabilities [4]. - The market is moving towards a model where energy storage systems must focus on long-term performance and lifecycle efficiency rather than just initial costs [4]. Group 5: Market Mechanisms and Revenue Models - The adjustment of the capacity compensation mechanism will enhance the value of energy storage, particularly for photovoltaic systems, by aligning compensation with their actual contribution to peak demand [7]. - The auxiliary service market is being restructured to allow energy storage to participate more actively, which could significantly increase revenue opportunities for storage systems [8][9]. Group 6: Long-term Industry Outlook - The transition to a market-driven pricing model for renewable energy is expected to stabilize the energy storage industry in the long run, particularly benefiting grid-connected storage and green electricity projects [10][11].
