Starting from March 6 through March 31, coastal regions in eastern China, including Shanghai, Jiangsu, Zhejiang and Fujian, will use green electricity supplied by wind and solar farms in Guangxi and Yunnan in southern China, with a total power supply of 314 million kWh, according to a recently signed green power trade deal. The deal also marked the first large-scale cross-regional green power trade of the year.
