The Department of the Navy (DON), U.S. Marine Corps (MC) and Arizona Public Service (APS) announced the completion of a 25-MW microgrid built on Marine Corps Air Station (MCAS) Yuma.

The completion was commemorated in a celebratory ribbon-cutting ceremony Thursday at MCAS Yuma, marking the start of commercial operations for the microgrid. In the event of a system-wide grid outage, the microgrid facility will provide enough backup power to cover 100 percent of current and projected base energy requirements. The microgrid will also be available to produce power to be sent to the grid, to benefit local APS customers.

APS will build, own, operate and maintain the microgrid facility at MCAS Yuma. In exchange for the use of DON land, APS will provide in-kind consideration in the form of backup power during grid outages, ensuring no interruptions to MCAS Yuma’s mission.

“Backup power is only one of a microgrid’s great benefits. They also are integral tools for providing our customers with reliable power when energy demand is at its highest. On a hot summer afternoon when Yuma customers are using the most power, we can draw energy from this microgrid,” said Mark Schiavoni, executive vice president and chief operating officer, APS. “This helps avoid the expense of building additional infrastructure to meet the peak needs of customers in summer and provides reliable energy when we need it most.”
