| Abstract | As the country's economy and population expand, energy and water consumption in the Philippines also rise. The current electrification and water supply methods are not only ineffective, unsustainable, and expensive, but it also fails to secure meeting future demands. Energy transition (Diesel-only to HRES) systems modeling studies show significant efforts in addressing energy issues by reducing electricity costs. Unlike in electrification, studies modeled only a few islands concerning water access. Because energy and water are interdependent, a separate analysis of the two issues may not yield the best possible solution. In this work, we extend the study of water access in the Philippines by conducting a techno-economic analysis of RO-coupled HRES on 634 off-grid islands with our in-house tool, ISLA. Each island houses a microgrid comprising solar PV, a wind turbine, lithium-ion batteries, and an additional or existing diesel generator to meet and sustain load and water demands. The levelized costs of 0.279 USD/kWh and 5.85 USD/m^3 as results show that the augmentation could save over 64% on electricity and 88% on water costs compared to current methods. However, for this to materialize, a total cost of 4.79 billion USD and an initial capital cost of 1.17 billion USD are required. These insights are utilized in formulating strategies to seek improved energy policies and private sector participation which addresses barriers to its deployment (such as cost). In addition, it is suggested that this study be extended by quantifying its profitability in addition to other RE and locations from other nations. |
