A new integrated MTEF analysis of a standalone hybrid renewable energy system applied to tribal residential schools and hostels in Tamil Nadu State,India with the impact of multiple tracking and loading including the scope of job creation factor

Abstract

This study presents an integrated MTEF (monetary-technical-emission-fuel) analysis for a standalone hybrid renewable energy system implemented in tribal residential schools and hostels in Sankarapuram Zone, Tamil Nadu, India. Using the HOMER Pro Microgrid Analysis Tool, three scenarios were evaluated: normal loading (100% of peak load), step loading (110% of peak load), and full renewable loading. Key findings include cost of energy ranging from $0.185 to $0.279/kWh, annual operating costs of $1466 to $10,448, and CO2 emissions between 7578 to 14,204 kg/year. The study highlights fuel consumption reductions (2895 to 5426 liters/year) and generator operation hours (699 to 2209 h/year). Generator analysis and job creation potential were also discussed, offering a sustainable power solution for tribal education. This work provides a framework for ensuring uninterrupted power in remote tribal areas.
