Microgrid Demonstration of Integrated Distributed Energy Resources (DER)

GTI Energy is supporting a microgrid demonstration of behind-the-meter distributed energy resources (DER) in partnership with the U.S. Army Corps of Engineers Construction Engineering Research Laboratory (CERL) at the Maine Army National Guard (MEARNG) East Bangor Campus.

This project focuses on integrated distributed power generation and energy storage to enhance energy security and operational efficiency at a mission-critical aviation support facility.

The microgrid is designed to operate in both grid-connected and off-grid modes and includes a suite of advanced technologies:

• Natural gas combined heat and power (CHP)
• Solar photovoltaics
• Battery energy storage systems (BESS)
• Smart microgrid controls
• Standby gensets

Together, these components form a resilient, flexible system capable of sustaining operations during grid outages or energy supply disruptions. The system will also reduce peak electric demand to significantly reduce utility costs. The CHP system alone is projected to deliver $72,000 in annual energy cost savings, supporting long-term cost reduction and enhanced performance. The project is currently underway and is scheduled for completion in 2028.
