T/HEESA 0001-2024 Active

Scope: This document stipulates the basic provisions for carbon emission calculation during the construction of power transmission and transformation projects, the carbon emission calculation for overhead transmission line projects, the carbon emission calculation for substation projects, and the carbon emission calculation method for cable line projects. This document is applicable to the carbon emission calculation during the construction of new and expanded overhead transmission line projects, substation projects, and cable line projects with voltages ranging from 35 kV to 750 kV in AC systems. Other projects such as DC (transmission and converter stations) projects, UHV projects, and medium- and low-voltage distribution projects can refer to and implement it accordingly. In addition to complying with the provisions of this document, the carbon emission calculation during the construction of power transmission and transformation projects shall also comply with the relevant provisions of current national documents. Main technical content: This document stipulates the basic provisions for carbon emission calculation during the construction of power transmission and transformation projects, the carbon emission calculation for overhead transmission line projects, the carbon emission calculation for substation projects, and the carbon emission calculation method for cable line projects.
