Polaris Solar Photovoltaic Network learned that on November 30, the National Energy Administration issued 326 energy industry standards including "Geothermal Well Structure Design Method" and 19 energy industry standards including "Code for Seismic Design of Hydraulic Structures of Hyower Project" in foreign languages Version, "Code for Seismic Design of Hydropower Engineering and Hydraulic Buildings" and other three energy industry standards revision notices. It includes three photovoltaic standards: off-grid solar photovoltaic power generation systems for villages and towns, design specifications for heat collection systems in trough solar thermal power plants, and design specifications for heat storage systems in solar thermal power plants.
