Core Insights - The China Meteorological Administration released the "2025 China Wind and Solar Resource Annual Report," which includes new features such as offshore wind resource analysis and assessments for large renewable energy bases [1][4] Group 1: Wind Energy Insights - The report indicates that the national wind energy resources for 2025 are expected to be normal, with average wind speeds of approximately 4.8 m/s at 100 meters and 5.1 m/s at 140 meters [2] - Certain regions, including North China, Northeast, and Northwest, as well as most of the Tibetan Plateau, have average wind speeds exceeding 6.0 m/s, indicating rich wind energy resources [2] - Offshore areas show even higher average wind speeds of about 7.8 m/s at 100 meters and 8.0 m/s at 140 meters, highlighting significant potential for wind power generation [2] Group 2: Solar Energy Insights - The report states that the overall solar energy resources for 2025 are expected to be slightly below average, with a total horizontal solar radiation of 1495.7 kWh/m², which is 25.1 kWh/m² lower than the average over the past 30 years [2] - Regions such as most of the Tibetan Plateau, western Inner Mongolia, and eastern Xinjiang have solar radiation levels exceeding 1750 kWh/m², marking them as the richest solar resource areas in China [2] - Most areas in China, except for the Sichuan Basin, are classified as having "rich" or "very rich" solar resources, which is favorable for solar power generation [2] Group 3: Report Characteristics - The report features three main characteristics: innovative foundational data, content alignment with current industry trends, and enriched scenario-based assessments [3][4] - The foundational data used for the wind and solar resource assessments is based on high-precision monitoring datasets developed by meteorological departments, which are superior to similar foreign products [3] - The report has removed outdated data related to 70-meter height assessments and included analyses for 140-meter heights to better support the evolving wind power industry [3] - It also includes quarterly resource analyses to reflect the temporal variations in wind and solar energy [3] Group 4: Practical Applications - The report serves as a critical component of the China Meteorological Administration's wind and solar resource monitoring and assessment operations, receiving attention from energy authorities, power companies, and research institutions [4] - Energy authorities utilize the report as foundational data for national renewable energy generation statistics, while power companies apply it for site planning and generation estimates [4] - The meteorological department aims to enhance the integration of energy meteorological data and technological innovation to support the "dual carbon" strategy and ensure national energy security [4]
