Core Viewpoint - The article discusses the strategic plan for solar energy development in the "Three North" regions of China, aiming to add 253 GW of solar capacity and rehabilitate 10.1 million acres of desert land by 2030, highlighting the importance of energy storage in supporting this initiative [1][3][12]. Group 1: Solar and Wind Energy Development - The "Three North" regions are rich in solar and wind resources, making them a priority for large-scale renewable energy projects [2]. - By 2030, the total installed capacity of large-scale wind and solar bases in desert areas is expected to reach 455 GW, with a focus on integrating energy storage solutions [3][12]. Group 2: Role of Energy Storage - Energy storage plays a crucial role in enhancing the utilization of renewable energy and stabilizing peak power output, with configurations of 0 to 200 MW of storage significantly improving peak capacity and renewable utilization [4]. - The integration of distributed energy storage systems is essential for enhancing system support capabilities and frequency regulation [4]. Group 3: Investment and Project Examples - Major power companies are adopting a "renewable + storage + coal/solar thermal" model, with energy storage typically comprising 10% to 20% of the total capacity [5]. - Notable projects include: - Xinjiang Tianshan Energy Base with a total investment of 54.7 billion yuan and a capacity of 14.2 million kW, including 1,200 MW of energy storage [6]. - Gansu Huaneng Tengger Desert Base with a total capacity of 15.2 million kW and 2,000 MW of new energy storage [6]. - Inner Mongolia Kubuqi Desert Base with a total capacity of 12.8 million kW and integrated energy storage [6]. Group 4: Challenges and Future Outlook - The construction of large-scale renewable energy bases faces challenges such as high investment costs, grid pressure, and difficulties in energy consumption [12]. - The government is exploring new models for local energy consumption, including direct supply of green electricity to specific users, which could enhance the integration of renewable energy with industrial development [12]. - The ongoing energy revolution is expected to continue with advancements in ultra-high voltage transmission, declining storage costs, and policy coordination [12].
