The purpose of this study is to suggest an investment plan for Turkey, which is dependent on foreign energy, that meets Turkey’s electrical energy demand between 2020-2039. Strategic investment plan for electricity generation is crucial in terms of ensuring sustainable supply security. Analytical Hierarchy Process (AHP), which is a multi-criteria decision-making method, was utilized to build this investment proposal. Under a series of data preprocessing techniques applied within the model, the subjectivity that is often observed in AHP has been largely eliminated, resulting in relatively more objective results. With the unique data preprocessing techniques and the AHP method applied within the study, a portfolio scenario that is in line with the strategic objectives of the Republic of Turkey Ministry of Energy and Natural Resources has been offered. With the obtained portfolio scenario, the research reveals findings that support the goals of ETKB. Accordingly in proportion to the energy sources used to meet increasing demand, it is predicted that while the use of coal, natural gas and hydroelectric within this production will decrease by 10.6%, 3%, and 4.3% respectively, the use of wind, sun and geothermal will increase by 1.68%, 4.34%, and 2.98% respectively. As a result, the suggested plan reduces the rates of external dependency, fossil fuel use, and emission values while increasing the use of renewable energy sources, employment potential, and security of supply. The results of the research are of great importance in terms of demonstrating that the goals in the 20-year strategic plan of ETKB are consistent.
