China targets integrated energy-meteorology service system by 2027

The China Meteorological Administration (CMA) and the National Energy Administration (NEA) have jointly issued guidelines outlining plans to establish a fully integrated energy-meteorology service system by 2027.

The document calls for a nationwide survey of wind and solar power resources, aiming to develop 1 × 1 km, hourly gridded resource assessment datasets, along with high-resolution solar resource maps. It also proposes enhancing dynamic monitoring and evaluation of solar resources by building high-accuracy, frequently updated databases.

In forecasting, the guidelines target seamless solar resource prediction, with a goal of reducing the 24-hour total solar irradiance forecast root mean square error (RMSE) to below 12%. For PV power output forecasting, the plan sets a target 24-hour accuracy rate of 89%, with particular emphasis on large-scale ‘desert, Gobi and arid region’ renewable bases as well as distributed PV systems.
