Basic Information
Scope
Scope: This standard specifies the key indicators, data collection, accounting methods, evaluation methods, and evaluation processes for the quantitative assessment of carbon emissions in substations. This standard applies to the carbon emission accounting and evaluation of substations with voltages of 110 kV and below. Main technical content: (1) Scope: This standard specifies the technical requirements for the quantitative assessment of carbon emissions in substations, including key indicators, data collection, accounting methods, evaluation methods, and evaluation processes.
