In Puerto Princesa, three new solar-powered trailers stood gleaming under the mid-morning sun. Their arrival—hailed as a game-changer in the country’s quest for inclusive electrification—was anything but ordinary.
Led by U.S. Ambassador MaryKay Carlson, officials from both the American and Philippine governments gathered at the National Power Corporation’s (NPC) Irawan Switching Station on May 16 for the ceremonial turnover of three mobile energy systems (MES), donated by the U.S. government to power remote, disaster-prone communities across Palawan.
“These MES are not just equipment,” Ambassador Carlson said during her remarks. “They are essential tools of resilience and innovation that have been proven to provide power to some of the most remote locations in the country.”
The technology—compact yet potent—is built for more than just convenience. Each unit carries 9.18 kilowatts of solar panels and a 70-kilowatt-hour battery, capable of supplying a full day’s electricity to 10 Filipino households. During emergencies, the systems can operate independently, powering satellite internet, computers, communications devices, and fans for a week on a single charge.
Philippine Energy Secretary Raphael Lotilla, NPC President Fernando Roxas, DOE Undersecretary Giovani Bacordo, and USAID Philippines Mission Director Ryan Washburn joined Carlson at the event. For them, the MES symbolizes more than just international cooperation—it’s a literal lifeline for off-grid communities.
“On behalf of the U.S. government, I thank the DOE, the NPC, the Energy Regulatory Commission, and all our partners for their leadership and collaboration in making sure that no Filipino is left in the dark, no matter where they live,” Carlson added.
The systems will soon be integrated into NPC-managed microgrids across Palawan, a province where access to consistent power remains a daily challenge for thousands. This new fleet of MES units is part of a broader strategy under USAID’s Energy Secure Philippines program, which aims to bolster the country’s energy resilience in the face of climate vulnerability and aging infrastructure.
Carlson noted that MES technology has already proven itself in past deployments. Since 2024, the U.S. government has provided similar units to support the Department of Energy’s Emergency Operations Center in Manila and to municipalities in Cagayan, where the MES kept essential services running during typhoon-triggered blackouts.
“Since launching the first MES unit last year, we have witnessed the MES units’ potential in action—from powering the DOE Emergency Operations Center during a blackout to enabling real-time government services in typhoon-hit areas of Cagayan,” Carlson said. “These mobile systems are flexible and are proven to provide reliable power to local communities across the Philippines.”
According to USAID, four additional MES units are scheduled for deployment in the country by the end of the year. While relatively small, their impact is expected to ripple widely—especially in archipelagic provinces like Palawan, where many still live without electricity or must rely on expensive diesel-powered generators.
