In 2025, the CGN Delingha 50 MW CSP demonstration plant delivered 1.46 billion kWh of electricity to the grid, hitting an all-time high.
CGN New Energy Delingh Co. stayed focused on its annual production and operation targets, concentrating on equipment governance, optimized O&M strategies, and overall system efficiency. Key efforts included boosting mirror-field flow rates, continuing the replacement of domestic swivel joints and hydraulic valve blocks, and carrying out detailed analyses of collector-interception rates while refining temperature-control logic. These measures raised the availability and operating efficiency of the solar-collection equipment, achieving a 3.7 % increase in annual generation even though direct normal irradiance fell by 0.2 %.
