Abstract [en]

Are the renewable energy systems applied for rural electrification in developing countries sustainable? What governs the sustainability of rural electrification systems? Verifiable sustainability indicators need to be identified within technical, social, economic, environment and institutional dimensions of the system under evaluation in a given specific context. The various methods used in assessing the sustainability indicators have been briefly reviewed in this paper. The sustainability indicators within each sustainability dimension are again evaluated for each alternative that are under consideration and compared with a reference case.  All the indicators do not necessarily have same importance. These indicators can have different weight based on their importance in specific context. The questionnaire survey has been conducted with the local experts to determine the weighting factor of different indicators in the local context and finally the indicators under each sustainability dimension has been aggregated into one single index based on ratio of the sustainability indicators of two objects under analysis.. This index could help to have better comparison among various off-grid technologies and enhance the feasibility study of these available alternatives. This paper specifically analyzes the sustainability of rural electrification in Nepal with the technological alternatives viz. solar home systems, wind home systems  and micro-hydro comparing with fossil based technology diesel generator as reference. The analysis shows that under prevailing policy and market infrastructure in Nepal, micro-hydro technologies have strong sustainability indicators in terms of technical, economical and environmental dimensions compared to other technologies, but this technology is comparatively weaker on its institutional and social dimensions which need more attention in the project design and implementation.
