Abstract: The waste of available resources and the harmful effects of toxic emissions play a fundamental role in the sustainability assessment of energy, production, transmission, and distribution sectors in the power industry. Investing in appropriate capacity allocation and accurate resource control can significantly reduce the negative effects of pollutant gas emissions and wasted energy in the electricity supply chain. The current paper introduces a DEA-based model for sustainability evaluation of the electricity supply chain through harmful substances management and greenhouse gas (GHG) control in the energy, power plant, transmission, and distribution sectors. The study aims to determine the limited and effective investment regions of supply chain divisions for pollutant gas abatement. Indeed, the proposed approach distinguishes between effective and limited investment opportunities for 10 supply chain divisions, as the investment increases in the divisions with a high level of investment opportunities provide a significant decrease in flare gas and greenhouse gases (GHG) in the energy and power plant sectors and wasted energy harness in transmission and distribution lines. In 60% of supply chains, the results show that there is a distribution line network with a high level of good investment opportunities. Manuscript profile
