Marine Corps Air Station (MCAS) Miramar

Photovoltaic panels on the roof of parking garages.

In FY16, the PV system generated 316 MWh, while the facility only consumed 209 MWh, creating a net-zero evaluation scenario.

In 2016, MCAS Miramar successfully demonstrated the islanding capability of a 250-kW battery storage and 230-kW PV microgrid system at the installation’s Public Works building. The center of the microgrid system is an innovative zinc bromide (ZnBr2) flow battery with titanium electrodes. The system also contains a public utility awareness display (PUAD) that shows real time energy data. The distributed energy project successfully offsets the building's electrical consumption and increases MCAS Miramar's resilience and energy security.
