Located in Qiaojia County, Zhaotong City, Yunnan Province, China, at an altitude of 2,800 to 3,100 meters above sea level is the largest single photovoltaic power plant in Yunnan that has been connected to the grid since the announcement of the "14th Five-Year Plan". The power forecast system of the project, accepted in August 2022, is provided by SPRIXIN and is currently in good operation.

The project is of positive significance to the completion of the "Dual Carbon" goals and to the green transformation of economic and social development in Yunnan. The average annual grid-connected power generation of the power plant can reach 425 million kWh, which can save about 130,000 tons of standard coal and reduce carbon dioxide emissions by about 320,000 tons per year compared with coal-fired power generation. Notably, the power plant is built over the ground of a ranch, achieving the common goal of ecological and economic win-win.

On the one hand, benefiting from its low latitude and high altitude, Yunnan has significant advantages in the wind and solar resources with top-ranking wind and sunlight utilization hours in the country, advantages that have made the energy industry an important pillar of the local economy. On the other hand, as the deployment and development of new energy in Yunnan continue, the issue of early warning of abnormal weather must be addressed, given the weather changes in the province. Some areas, for example, are vulnerable to extreme weather such as rain, fog, freezing, cold waves, and snowfall, resulting in ice-covered wind turbines and snow-covered photovoltaic panels, which directly affect the power generation assessment of new energy stations and jeopardize the safety and stability of power grid operation.

In this regard, SPRIXIN suggests that with the onset of the winter cold wave, all regions susceptible to cold air should attach importance to abnormal weather forecasts and early warning methods, improve renewable energy-related meteorological observations, and carry out refined load and new energy output forecasts. SPRIXIN has developed an "Early Warning Platform of Abnormal Weather" to help new energy practitioners avoid loss from extreme weather, and reasonably adjust power forecast values accordingly, effectively improving the power generation output forecast accuracy of new energy stations under complex weather conditions, and ensuring safe and stable operation of the power grid.
