Özet:

Aim: This study aims to select the most suitable location for the Solar Power Plant (SPP) to be established in Turkey, using the multicriteria decision-making (MCDM) techniques among the alternative provinces of Istanbul, Nevşehir, and Bilecik. For this purpose, in the first stage, location selection conditions in terms of legislation, efficiency of the power plants, and social, geographic, and economic impacts were taken into account to determine the final site selection criteria for solar power plants. In the second stage, criterion weights were calculated using the Analytical Hierarchy Process (AHP) method. In the third stage, a compromise solution was obtained by ranking the alternatives determined by the VIKOR method according to their superiority. Method: To determine the final site selection criteria for solar power plants, AHP and VIKOR methods, which are Multi-Criteria Decision Making methods, were applied, taking into account the site selection conditions in terms of legislation, the efficiency of the plants and social, geographical and economic impacts. Super Decisions, which is frequently used as a computer program in AHP method applications, accompanied this study. When previous studies on this subject in the literature are examined; Although there are many studies using the AHP and VIKOR methods separately, it has been observed that the number of academic studies examining their combined effects is quite limited and the number of criteria used in the studies is quite low. The reason for using AHP in the research is that it is still an up-to-date method and is the most frequently used Multi-Criteria Decision Making technique in operations research. On the other hand, VIKOR was used because it was aimed to guide practitioners and contribute to the literature by utilizing a different decision-making approach. Findings: In this study, three provinces where a solar power plant can be established were discussed, and the most suitable one of these provinces was selected using multi-criteria decision-making methods. Four main criteria were used: technical, social, and geographical. On the other hand, twelve sub-criteria were used: land cost, power transmission line distance, regional incentives, sunshine duration, temperature, land radiation amount, slope, distance to fault lines, precipitation amount, number of snowy days, distance to settlement area, and labor force. The AHP method was used to determine the criteria weights, and the VIKOR method was used to list the alternatives. Results: The findings showed that Nevşehir is the best location for the solar power plant. It is expected that the research results will guide practitioners and academicians working on solar energy.
