| Abstract | This research explores the techno-economic feasibility of supplying electricity entirely from renewable energy sources in a stand-alone power system for Lampang Province, Thailand. The analysis is conducted using HOMER Pro to model and optimize hybrid renewable energy configurations combining solar photovoltaic (PV), biomass, and small hydropower systems with energy storage and power converters. The assessment considers resource availability, hourly load demand, capital and operating costs, and key economic parameters, including discount rate and system degradation.The results reveal that a fully renewable stand-alone system can achieve 100% renewable energy penetration with zero greenhouse gas emissions. The optimized configuration yields a Levelized Cost of Electricity (LCOE) of 0.126 USD/kWh and a Net Present Cost (NPC) of roughly 1.68 billion USD. The system demonstrates high reliability, with zero unmet load and a reserve margin of 21.8%, ensuring supply adequacy under peak demand conditions. However, the system exhibits excess electricity generation of approximately 22.6%, indicating opportunities for further optimization in system sizing and energy utilization.Comparative analysis shows that a mid-level renewable scenario achieves the lowest LCOE of 0.093 USD/kWh with a renewable fraction of 45.7% and CO₂ emissions of 321 million kg/year, representing the most economically attractive option for near-term implementation. In contrast, the business-as-usual scenario results in higher emissions exceeding 515 million kg/year with a renewable fraction of only 20.7%.Overall, the findings confirm that a 100% renewable stand-alone power system at the provincial scale is technically feasible and environmentally sustainable, although further optimization is required to enhance economic performance. This study provides critical insights for energy system planning and supports Thailand’s transition toward a sustainable, low-carbon, and energy-independent future. |
