The guam power authority (GPA) is seeking federal funding to purchase and install a modular microgrid controller that will improve grid control, emergency response, and power restoration…

The Department of the Interior's Office of Insular Affairs awarded $1.0 million to the Guam Power Authority (GPA) on October 28, 2025, under the Economic, Social, and Political Development of the Territories program (CFDA 15.875) to procure and install a modular microgrid controller on Guam. The primary deliverable is a fully operational microgrid controller integrated into an existing distribution circuit serving critical public infrastructure, including healthcare facilities, water systems, and emergency operations centers. The system will provide enhanced real-time monitoring and control capabilities, enable load management and circuit islanding during grid disturbances, and support faster, more targeted power restoration following emergencies. GPA will directly manage all project activities through the ultimate completion date of September 30, 2030, with no subrecipients involved.

The project aims to strengthen energy resilience and emergency response capabilities across Guam's critical infrastructure in response to severe weather and other grid disruptions. Planned activities include staff training on system operation, performance testing under simulated and live conditions, and integration with GPA's existing control systems. The scalable solution is designed to serve as a foundation for potential future microgrid deployments across the island, ultimately benefiting all Guam residents through improved grid reliability and the ability to maintain power to essential services during outages.

Activities

GPA will procure a modular microgrid controller and integrate IT into an existing distribution circuit that serves essential services such as healthcare, water, and emergency operations. The controller will be connected to GPA's existing systems and configured to allow for real-time monitoring, load management, and islanding of the selected circuit during grid disturbances. Staff will be trained in its operation, and the system will be tested for performance under simulated and live conditions. Expected deliverables or outcomes: - one modular microgrid controller fully installed and operational - enhanced real-time visibility and control over the selected circuit - the ability to isolate and maintain power to critical facilities during outages - faster and more targeted power restoration following emergencies - a scalable solution for potential future microgrid deployments intended beneficiaries: the primary beneficiaries are guam residents and government agencies that depend on uninterrupted power for essential services. The project will improve reliability for facilities such as hospitals, water systems, emergency response centers, and shelters. Long-term, the entire island benefits from improved grid resilience.

Subrecipient activities

No subrecipients are planned at this time. All project activities will be managed directly by GPA.
