The measures in the documents will have a positive impact on the development of renewable energies, according to sources with the NEA.
One of the main goals of this round of reforms is to solve the problem of curtailments of wind, solar and hydropower.
The six documents provide a policy basis for securing the total amount of renewable power to be purchased, which is vital to ensure sustainable and healthy development of the renewable sector in the future, the NEA said.
According to the new documents, renewables such as wind, solar and biomass will enjoy priority in grid connection and power generation.
The new market mechanism will encourage the sales of renewable power, across regions if necessary, and power generators and consumers will be able to negotiate directly for supply deals, a practice monopolised by the grid operator under the old system.
