SHFRP New Energy has produced the world's longest wind power glass fiber blade S90, and the domestic longest wind power blade S102. On 02 September 2021, the onshore blade S89, 89 meters long equipped with a new generation of electric wind power product platform units was successfully rolled off the assembly line. Production cuts, high coal prices, and the Chinese government's determination to cut emissions caused a severe power supply crunch. Amid economic recovery from the COVID-19 pandemic, the cost of thermal coal has almost doubled this year to the increased demand for industrial use of electricity.
