《关于促进光热发电规模化发展的若干意见》解读之一︱加快构筑新型电力系统重要支撑 开启我国光热发电规模化发展新征程

Core Viewpoint - The article discusses the importance of promoting the large-scale development of solar thermal power in China as part of the country's efforts to transition to a green economy and achieve carbon neutrality goals. The issuance of the "Opinions on Promoting the Large-Scale Development of Solar Thermal Power" is a significant step in this direction [3][4]. Group 1: Development Background - Solar thermal power has undergone 20 years of development in China, starting from the "863 Program" initiated by the Ministry of Science and Technology in 2006. Despite advancements, the cost remains high compared to wind and solar power, and supportive policies are still lacking [4]. - The "Opinions" aim to clarify the scale, application scenarios, implementation paths, and support policies for solar thermal power, which is crucial for promoting green energy transition and enhancing the stability of the power system [4]. Group 2: Strategic Layout and Design - China has significant solar thermal resources primarily located in regions like Inner Mongolia, Qinghai, Gansu, Xinjiang, and Tibet. The "Opinions" set a target of approximately 15 million kilowatts of installed capacity, which will enhance system regulation capabilities and support the integration of wind and solar power [5]. - The document encourages local planning for solar thermal power projects, ensuring that they align with regional industrial development needs and support the construction of energy parks with high proportions of renewable energy [5]. Group 3: Application Market - Solar thermal power is a green and grid-friendly energy source that can provide heating and steam, with applications spanning power generation and heating. The market can be categorized into three main areas: optimizing solar thermal power in renewable energy bases, constructing large-capacity solar thermal power plants in regional power systems, and integrating source-network-load-storage systems [6][7]. Group 4: Support and Regulation Capabilities - The initial demonstration projects have validated the technical feasibility of solar thermal power, leading to a gradual increase in installed capacity and a decrease in costs. However, further exploration of its capabilities in frequency regulation, voltage regulation, and peak shaving is necessary [9]. - As of now, approximately 1.62 million kilowatts of solar thermal power projects are operational, with about 2.7 million kilowatts under construction. The "Opinions" emphasize the need to enhance the response capabilities of solar thermal power systems [9]. Group 5: Technological and Industrial Innovation - Continuous innovation in technology and industry is essential for reducing costs in solar thermal power. Key areas include high-parameter large-capacity systems, breakthroughs in critical technologies, and collaboration across the industry chain to enhance competitiveness [10]. - The "Opinions" advocate for supporting technological innovation, encouraging disruptive technologies, and establishing a standardized system for the solar thermal industry [10]. Group 6: Policy and Market Coordination - The initial investment and costs of solar thermal power remain high, making it challenging to achieve grid parity under current market conditions. Therefore, policy support is crucial for creating a favorable environment for large-scale development [11]. - The "Opinions" propose increasing policy support, facilitating fair market participation, and establishing incentive mechanisms to enhance the economic viability of solar thermal projects [11].
