山东新能源电价改革方案落地 将助力储能从发展期走向成熟期

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].
