Core Viewpoint - The Ningxia Hui Autonomous Region Development and Reform Commission has decided to abolish the notifications regarding the promotion of healthy and orderly development of energy storage and the pilot projects for new energy storage in 2022, indicating a shift in policy direction for energy storage initiatives in the region [1][8]. Summary by Relevant Sections Abolished Notifications - The abolished documents included guidelines on the renewable energy storage ratio, the frequency of energy storage project utilization, and compensation for pilot project peak shaving [2]. Previous Guidelines - The notification issued on July 14, 2021, mandated that renewable energy projects must have a storage configuration ratio of no less than 10% and a continuous storage duration of over 2 hours. New approved projects were required to have storage facilities operational simultaneously with renewable projects, and existing projects were to complete their storage facility operations by the end of December 2022 [3]. Market Mechanism - The previous guidelines encouraged energy storage to participate independently in market transactions, integrating energy storage trading into the existing auxiliary service market rules in Ningxia, and clarifying trading varieties and pricing mechanisms [4]. Priority Utilization - Agreements were to be signed between grid companies and energy storage enterprises to ensure priority utilization of storage facilities, with a minimum of 250 complete charge and discharge cycles per year [5]. Pilot Project Details - The notification from May 10, 2022, outlined the scope and scale of pilot projects for 2022, focusing on areas with abundant renewable resources and high peak shaving demand. Each region was limited to two pilot projects, with a total scale not exceeding 200 MW/400 MWh [6]. Support for Advanced Technologies - The pilot projects included support for advanced energy storage technologies such as vanadium flow, compressed air, flywheel, and sodium salt, with individual project scales capped at 100 MW/200 MWh. A compensation price of 0.8 yuan/kWh was offered for peak shaving services, and projects were prioritized in the auxiliary service market [7]. Policy Abolishment Announcement - The decision to abolish the aforementioned notifications was made to comply with the Fair Competition Review Regulations and to facilitate the integration into a unified national market, effective immediately upon announcement [10].
