Under the“double carbon”target

pumped storage will bring new opportunities to participate in carbon trading market.Combined with the existing Chinese certified emission reduction project methodology in the electric power industry

a quantitative model for carbon emission reduction of pumped storage based on emission factor method is established. Firstly

the existing CCER projects in the power industry are investigated

and the key elements of the methodology and calculation criteria of CCER projects are analyzed. Then

based on the carbon emission reduction mechanism of pumped storage during pumping period and peak load period

a quantitative carbon emission reduction model of pumped storage project is constructed. Finally

based on the analysis of a regional power grid

the carbon emission reduction of pumped storage is calculated. Examples analysis shows that the model can effectively calculate the carbon emission reduction of pumped storage

and the carbon emission reduction benefit is significant.
