[AGE28-03] Preliminary estimation and analysis of the renewable energy potential of Laguna province, Philippines
キーワード：Energy systems, Geothermal energy, Geographic information systems, Hydroelectric power, Renewable energy (RE), Sustainable development
Laguna is one of the few provinces in the Philippines that is powered by all effective types of renewable energy (RE) sources: biomass, geothermal, hydroelectric, solar, and wind. With the province's growing rural, suburban, and urban populations, it is of prime importance to increase adoption or mainstream the transition toward renewable energy sources. This is projected to ensure a stable energy supply for Laguna while also meeting lower carbon emissions targets set by various sectors and local government units. Currently, the province's primary RE sources come from geothermal and hydroelectric power. In contrast, coal power plants from other provinces are still the largest source of power for consumed electricity in Laguna.
This study aims to create analyses and estimate Laguna's RE potential using geographic information systems (GIS) and other software, with supplied data from the Philippine Department of Energy (DOE-PH) and the Department of Science and Technology (DOST-PH). A preliminary assessment shows that solar energy and hydroelectric energy systems have the largest RE potential for the province; for wind energy, the eastern municipalities of the province can efficiently accommodate wind turbines of 10m in height (7.99 m/s, with mean power density at 580 W/m2) at any given time of the year. Hydroelectric power will remain to be a large RE potential contributor to the province's projected energy demand in the future. Data also shows that floating solar photovoltaics in Laguna de Bay, the country's largest lake, can provide an estimated 27% sustained capacity factor throughout the year.
The further estimation that includes future RE power plants and facilities in Laguna should be undertaken, along with the energy cost assessments and RE potential analyses that integrate more battery energy storage systems in the province. The results of this study can provide a basis for RE policy & management recommendations that are aligned with the province's sustainable development and decarbonization initiatives.
