Case Studies: Microgrids in the Philippines
The Philippine Rural Electrification Program has already adopted microgrids in areas like Palawan, Mindoro, and Mindanao. These projects demonstrate how microgrids improve energy reliability, especially in off-grid islands.
Polillo Islands (Clustered Microgrids): A study analyzed the potential of clustered hybrid renewable energy systems (HRES) for the Polillo Islands, consisting of solar PV, energy storage, and diesel generators. Clustered microgrids showed lower costs compared to decentralized systems, while enhancing reliability and resilience. This configuration is particularly useful for off-grid islands vulnerable to typhoons, such as those in the Philippines.
Gilutongan Island, Cebu: This project implemented a hybrid microgrid combining rooftop solar PV, batteries, and diesel generators to provide 24-hour electricity access. This system addressed the energy trilemma of sustainability, affordability, and reliability in a previously underserved off-grid community.
HOMER Pro Microgrid Optimization: In a community reliant on costly diesel generators, HOMER Pro software was used to design a solar PV and battery-integrated system. This reduced dependency on diesel, cutting costs and providing sustainable, reliable power for rural areas.
These examples demonstrate how microgrids, tailored to the unique needs of local contexts, can improve energy access, reduce costs, and enhance resilience against natural disasters.
