Techno-Economic Analysis of Energy Systems in Thakle Namuna Basti - A Case Study

The electrical supply system in most underdeveloped nations is incredibly undependable. The country’s existing distribution system has experienced regular power outages due to population growth, industrial expansion, rough terrain, and a long-distance transmission network. The conventional approach to centralized generation and transmission is failing to address this challenge and as a response, the utilization of renewable energy sources is expanding day by day to alleviate the energy crisis. The purpose of this study is to perform a techno-economic analysis of a 100% renewable off-grid and on-grid hybrid energy system for the electrification of Thakle Namuna Basti, a small communal village in Melamchi, Sindhupalchwok. The HOMER Pro 3.14 program is used to analyze the feasibility of the suggested hybrid power system. The available resources are provided as an input parameter along with load data and HOMER Pro optimizes the list of system architecture for that specific site. In addition, sensitivity analysis is performed for the proposed HES (Hybrid Energy System). The main outcome of the project is to find out the best system architecture based on various economic parameters such as NPC (Net Present Cost), LCOE (Levelized cost of electricity) and Operating and Maintenance Cost. The system having lowest NPC and LCOE makes the best system architecture.
