Group 1 - The company Gansu Water Conservancy and Hydropower Survey and Design Institute, a subsidiary of Gansu Consulting, is focusing on the vast desert land resources in the province [1] - The company is actively developing the Shagehuang New Energy Base, leveraging the Tengger Desert [1] - It has undertaken multiple planning research and surveying design projects and is expanding its engineering general contracting business [1]

Core Points - The Gansu Longdong DC supporting renewable energy 330 kV transmission project has achieved full line connectivity, marking a significant milestone in the construction of the "Shagou Desert" renewable energy base and the "Longdong into Shandong" strategy [1][3] - The project is a key supporting initiative for the "Longdong into Shandong" ±800 kV UHVDC project, designed to transmit 8 million kW of electricity, capable of delivering over 36 billion kWh annually to Shandong, meeting the annual electricity needs of nearly 10 million households [3][5] Project Details - The total length of the project is 324.262 kilometers, with 677 new transmission towers constructed [5] - The project faced challenges such as complex terrain and harsh environmental conditions, requiring meticulous planning and coordination among various departments to ensure safety and quality during construction [3][5] - The project is expected to enhance the renewable energy transmission capacity of the Longdong region by forming a robust power grid system in conjunction with other existing renewable energy transmission lines [5] Future Plans - The company is currently focused on installing line accessories and debugging substation equipment to ensure the project is ready for operation [5] - The construction experience gained from this project will be utilized to improve the management standards of future major power projects, emphasizing standardized processes, refined risk control, and efficient collaborative management [5]

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].
