Study on the Assessment Method of Carbon Emission Reduction Potential in Electricity Transmission and Distribution Project Construction

With power transmission and distribution projects as the object, this paper defines the carbon emission reduction potential, constructs a carbon reduction potential calculation model, and studies specific procedures of data collection, modeling, and solution. It applies the K-means algorithm for clustering, which can identify processes with significant carbon emission reduction potential through analysis for optimized management. It selects sectional works including substation installation works and civil construction works from the two typical power transmission and distribution projects in China for model application and case studies. The study results show that the carbon emission reduction of the two works are 70.248 kg CO<inf xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">2e</inf> and 127.998 kg CO<inf xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">2e</inf>, respectively, with emission reduction potential of 23.97% and 48.57%, respectively.
