Access to electricity is generally recognized as an important factor for economic and social development. Moreover, the world energy consumption depends on the use of limited resources like fossil fuels that induce adverse impact on the environment and society. As an alternative, renewable energies turn into crucial alternative energy ensuring sustainable energy needs and taking care of society, economy and the environment. In order to combat such issues, the United Nations has declared universal access to affordable, reliable and modern energy for by 2030. In many cases, different types of renewable energy systems are being developed to serve energy need without considering the best alternative. Thus, this paper tries to prioritize the installed Decentralized Renewable Energy (DRE) systems for rural electrification in Nepal by analyzing nineteen sustainability indicators related to four sustainability dimensions - technical, social, economic and environmental. An Analytical Hierarchy Process-Online Software (AHP-OS) model is used for ranking various DRE systems. Suitable goals, criteria, sub-criteria, and alternatives are developed after reviewing pertinent literature and consultation of the experts. The results reveal that micro-hydropower is the best electrification option followed by the solar home system, solar mini-grid, and wind-solar hybrid for decentralized electrification in Nepal. Biomass is found to be the least prioritized alternative in Nepal. The outcome of the research can help the policy-makers and decision-makers in shaping energy policies, plans, and programs, and foster sustainable energy development in the country. Similarly, the relevant stakeholders will be benefited by improving their products and services in the future.
