["Beijing's New Energy System Plan during the "15th Five-Year Plan" Period": Focusing on the R&D and equipment manufacturing of perovskite solar cells and high-efficiency photovoltaic modules and promoting building photovoltaic integration] On October 28, the Beijing Municipal People's Government issued the "Beijing New Energy System Plan during the "15th Five-Year Plan" period. It pointed out that the high-end level of the wind power industry should be improved. Focus on the research and development of core components such as composite materials for large-megawatt wind turbine blades, break through key technologies such as strong wind protection, strengthen the agglomeration effect of wind power company headquarters, and create decentralized wind power demonstration projects. Expand the application of photovoltaic technology innovation scenarios. Focus on the research and development and equipment manufacturing of perovskite solar cells and high-efficiency photovoltaic modules, and promote the integration of building photovoltaics. Accelerate the industrial application of geothermal and heat pumps. Promote the research and development and manufacturing of key technical equipment such as high-efficiency heat exchangers, cultivate key heat pump equipment manufacturing enterprises, and promote large-scale application. Strengthen research on smart grid technology and equipment. Focus on the research and development of core components such as power chips, strengthen research on key technologies such as intelligent power transmission and transformation equipment, expand the scale of equipment manufacturing in Beijing, and explore business model innovations such as vehicle-network interaction and virtual power plants. Promote the cluster development of new energy storage industries. Promote the research and development of solid-state, liquid flow and other battery technologies, develop system integration and high-end manufacturing, and promote the application of grid-side and user-side energy storage, with the installed capacity of new energy storage reaching 600,000 kilowatts.
