In recent years, the National Energy Administration has issued a series of policies to promote the rapid development of clean energy. By the end of 2020, clean energy consumption accounts for 24.3% of primary energy consumption, and the installed scale of hydropower, wind power, and photovoltaic power generation all rank first in the world. This comprehensive supervision aims to promote the efficient use of clean energy, urge relevant regions and enterprises to strictly implement the national clean energy policy, optimize the grid-connected access and dispatching operation of clean energy, standardize the transactions of clean energy, find out obvious problems in the development of clean energy in time, ensure the efficient use of clean energy, and further promote the high-quality development of the clean energy industry. This supervision focuses on 6 aspects: Firstly, check the completion of the main objectives of clean energy consumption and the implementation of key tasks; The second is to figure out the weight of renewable energy power consumption. Thirdly, check the grid connection of clean energy power generation projects; Fourth is the optimal scheduling of clean energy; Fifth is its consumption of cross-provincial transactions; Sixth is the participation of clean energy in the market.
