Abstract
Currently, more than 90% of the electricity produced in the Kingdom of Saudi Arabia originates from fossil fuels. Under the Vision 2030 initiative, the Kingdom aims to derive 50% of its energy from renewable sources by 2030. This study presents a comprehensive evaluation and ranking of renewable energy technologies for a selection of cities across the country using an integrated methodology that combines the Analytic Hierarchy Process (AHP) and Technique for Order of Preference by Similarity to Ideal Solution (TOPSIS). The focus is on four renewable sources, namely Photovoltaic (PV), Concentrated Solar Power (CSP), Wind Energy, and Fuel Cell, each with a capacity of 10 MW. The performance of these renewable sources is assessed in five different cities of Ar’Ar, Ha’il, Riyadh, Najran, and Al Baha. The evaluation considers multiple criteria that encompass climate, environment, and social aspects, providing a holistic assessment of the alternatives. The AHP method is employed to determine the relative weights of the criteria, ensuring consistency in the pairwise comparisons. The TOPSIS method is then applied to rank the alternatives based on their performance scores. The results highlight the preferences and relative performance of the different renewable energy technologies across the considered cities. Fuel Cell technology emerges as the most favorable option in all the cities with a score higher than 0.68, demonstrating superior capacity factor (92.4%), minimal environmental impact, and reliable power generation but with a negative net present value (NPV) of − 12.22 M$. Wind Energy and CSP technologies followed in ranking, indicating their competitiveness and suitability as renewable energy options by producing in excess of 25,000 MWh/year. PV technology demonstrates competitiveness across all cities with the lowest levelized cost of electricity (LCOE) (4.33 C/kWh) and quickest payback period (12.4 years). The findings of this study provide valuable insights for decision-makers and stakeholders involved in the selection of appropriate renewable energy technologies. The rankings serve as a valuable tool in informing decision-making processes and facilitating the transition to sustainable energy systems.

AHP method for determining criteria weights
To evaluate the values in light of the chosen criteria, it is necessary to ascertain the weights of the criteria. The AHP method is employed for this purpose. Details of the methodology and process behind AHP can be found in foundational literature (Alanazi and Alanazi 2023; Mohammad et al. 2021; Mu and Pereyra-Rojas 2018). The fundamental idea behind this method is to create a comparison decision matrix that enables comparisons between each criterion and its pair using certain computations and procedures to produce constant weights for each criterion.
TOPSIS Method for ranking alternatives
Once the criteria weights have been established, the subsequent task involves ranking the alternatives in order of preference. To accomplish this, the TOPSIS method was employed. The TOPSIS method utilizes the concept of ideal and anti-ideal solutions to assess the degree of proximity of each alternative to the ideal choice. This method serves as a valuable tool in MCDM, offering a systematic approach to evaluating and ranking alternatives based on their overall performance. Details of the methodology and process behind TOPSIS can be found in foundational literature (Bilgili et al. 2022; Solangi et al. 2021; Rani et al. 2020).
AHP calculation
Table 14 shows the pairwise values of the comparison matrix. It shows a comparison matrix that represent the relative importance/preference of one element compared to another element. The values are assigned on a scale, ranging from 1 to 9, where 1 indicates equal importance/preference, and higher values indicate increasing preference or importance. The priority of each criterion was carefully selected after carrying out extensive literature review of renewable energy technologies.
Once the pairwise comparison matrix is defined, the normalized pairwise matrix Table 15 is derived. The Normalized Pairwise Matrix is a mathematical transformation of the pairwise comparison matrix that ensures the values are normalized and consistent across all elements. The pairwise values in the comparison matrix are divided by the sum of the values in their respective columns. This normalization process ensures that the values represent relative importance or preference ratios that add up to 1 for each column.
