Mindoro Medical Center-Calapan, Inc. (MindoroMed) is set to become the first hospital in the Philippines to operate using both solar power and a Battery Energy Storage System (BESS), following an expanded partnership with EEI Power Corporation, the energy arm of EEI Corporation. BOS Balance of Storage Systems AG, a pioneering German energy tech com-pany, has successfully deployed a solar island system at the Luuk Municipal Hospital in Sulu, Philippines, and thereby solved the chronic electricity problem the hospital faced for years. The Southeast Asian state Philippines, which consists of more than 7,600 islands, faces major challenges to its national electricity. This case study highlights Mary Johnston Hospital's energy solutions in response to the global call for environmental stewardship. It will also discuss the challenges, opportunities, and outcomes from each phase of the projects. The summary is based on the initiative's implementation, which ran. TL;DR: In this article, an analysis proved that Philippine General Hospital could achieve these goals through the installation of a solar array and a lighting retrofit, which would result in a yearly seven percent decrease in electricity consumption and total of PHP 458,869,500 (almost $9 million). The Masinloc Battery Energy Storage System (BESS) is the first battery energy storage facility in the Philippines and one of the first in Southeast Asia. We started our venture into battery energy storage technology in 2018 when we acquired this 10 MW system from AES Philippines.
