Hydro-Sun Harmony: An Innovative Hybrid Power Plant Model for Hill Tracts Energy Independence

Bandarban, a remote stagnation in southern Bangladesh, struggles with a serious shortage of energy. To address this difficulty, a novel model that strategically combines photovoltaic (PV) solar and hydroelectric technologies has been developed. The objective is to maximize energy production and ensure a steady supply of power for populations located in hill tracts. This integration holds the promise of achieving energy independence and delivering comprehensive socio-economic and environmental benefits to the local populace. Through extensive study using HOMER software, the most effective configuration-which consists of a 41.1 kW converter system, a 17.3 kW hydro generator, and a 66 kW PV system-was found. With a Net Present Cost (NPC) of 176k USD and a Levelized Cost of Energy (LCOE) of 0.0396 USD/kWh, this arrangement satisfies the Palika Para community's energy needs exclusively through renewable sources, demonstrating both economic viability and sustainability. The suggested model has undergone an analysis of financial measures. The findings indicate an 8.9-year Simple Payback time, a 6.5% Return on Investment (ROI), and an Internal Rate of Return (IRR) of 9.5%. The proposed model demonstrates robust financial viability, ensuring continual sustainable energy generation and long-term profitability. The suggested Hydro PV Hybrid Power Plant Model is a paradigm-shifting move toward sustainable energy solutions that promotes socioeconomic development and environmental resilience in a variety of geographic contexts, making it a model for similar places around the world.
