Using multi-criteria decision analysis for sustainability of combined cycle power generation indicators in Indonesia: An industrial perspective

Abstract

Combined Cycle Gas Turbine Plant is one of the fossil fuel power generations that has become the priority of the fuel-switching program by the Indonesian government to reduce greenhouse gas emissions. Various indicators can be used to assess the sustainability of the power plant. However, the solution for each indicator is challenging to implement at once by the power industry. This paper presents the determination of important indicators from the industry stakeholder by using a multi-criteria decision analysis approach, which affects the sustainability of power plants. The result of this research shows that the environmental dimension has the most important scale value 0.6 of 1 compared to the social and economic dimension, and the primary elements that must be managed on environmental aspects are emissions related to the quality of the ecosystem. Our results can be used in assessing the sustainability of Combined Cycle (CC) Gas Turbines, especially in Indonesia.
