Analysis on Electricity System low-carbon Transformation — A Case Example from Fujian Province

This paper uses SBM-NDEA model to measure the efficiency of electricity low-carbon transformation in 30 regions of China, and analyzes the level of electricity low-carbon transformation between Fujian province and other regions, further divides the transformation efficiency of power sector in Fujian province, and deeply explores the optimization path. We find: (1) the average efficiency of China's electricity low-carbon transformation has fluctuated around 0.45 in the past decade, and the eastern and western regions are greater than the national average level; (2) for Fujian Province, the electricity low-carbon level of Fujian province leads, but the electricity low-carbon transformation efficiency growth rate of Fujian province still needed further improvements, which is mainly caused by the inefficiency of electricity transmission and distribution department; (3) the construction of the spot market of electric power helped to solve the efficiency problem of the power transmission and distribution departments in Fujian Province to some extent, but there are still many deficiencies. Finally, we provides some suggestions for the optimization of electricity transmission and distribution department in Fujian.
