Techno-Economic Assessment of Solar Power Plants on River Land in Indonesia Using HOMER Pro
Journal Title: Journal of Urban Development and Management - Year 2024, Vol 3, Issue 3
Abstract
The increasing urgency of climate change mitigation necessitates the adoption of renewable energy sources to meet the growing demand for clean energy. Solar energy, in particular, presents a viable solution, contingent on the availability of sufficient land to optimize power generation. River land offers an alternative location for solar power plants, potentially conserving valuable land resources while providing a natural cooling medium for solar panels to enhance efficiency. This study evaluates the techno-economic feasibility of establishing a solar power plant system (PLTS) on river land in Surakarta City, Indonesia, using simulations conducted with the Hybrid Optimization Model for Electric Renewables (HOMER) software. The simulation considers both on-grid and off-grid systems, with a daily energy demand of 2,947.236 kWh projected over a 25-year period at the Tirtonadi Dam site. The On-Grid system demonstrated a total annual energy production of 885,358 kWh, significantly outperforming the off-grid system, which produced 34,400 kWh annually. The Net Present Cost (NPC) for the on-grid system was calculated to be USD 1,805,634.01, while the off-grid system's NPC was substantially lower at USD 1,970.18. The Levelized Cost of Energy (COE) for the on-grid system was found to be USD 0.09 per kWh, compared to USD 0.10 per kWh for the off-grid system, indicating favourable investment potential. The breakeven point (BEP) for the On-Grid system was achieved in the 0.54th year. The initial capital expenditure required to implement the on-grid PLTS at Tirtonadi Dam was estimated at approximately USD 47,782.10, while the off-grid system's initial cost was around USD 1,923.77. These findings suggest that the deployment of solar power plants on river land, particularly with an on-grid configuration, is a technically viable and economically advantageous approach to enhancing renewable energy capacity in Indonesia.
