NEW CUMBERLAND, Pa. –
In a significant step towards energy independence and operational resilience, Defense Logistics Agency Distribution Sigonella, Italy, unveiled its new solar array and Battery Energy Storage System with a ribbon-cutting ceremony on January 15.
This cutting-edge microgrid is the first of its kind in DLA and Navy Region Europe, Africa, Central, marking a major milestone in the Department of War’s pursuit of sustainable and secure energy solutions.
The project, which had a combined cost of less than $2 million for two systems, builds upon a cost-saving initiative that began around 2016 with the installation of solar photovoltaic systems on several buildings at Naval Air Station Sigonella. Those initial systems proved highly effective, saving over $100,000 annually and paying for themselves by 2022. However, to enhance mission resilience during power outages, the new project integrates a BESS and microgrid controls.
The newly inaugurated system features sodium nickel chloride batteries that store excess solar energy to provide power during nighttime and cloudy conditions. Each of the two BESS installations can provide up to 400 kilowatt-hours of energy. During a utility outage, the microgrid seamlessly transitions to "island mode," ensuring an uninterrupted power supply by combining stored battery energy, solar generation, and generator support. The system is designed to sustain continuous operations for up to 14 days on a single tank of fuel.
The long-term benefits for DLA Distribution Sigonella, Italy, are substantial. Beyond the crucial advantage of enhanced operational resilience in an area prone to power outages, the system will significantly reduce fuel consumption and logistical demands associated with generator use. This translates to a safer and more focused work environment for the diverse workforce of U.S. military personnel, Italian national employees, and civilians.
The project was a collaborative effort between DLA Installation Management, and Naval Facilities Engineering Systems Command Sigonella.
“This system will allow for DLA Distribution Sigonella to support the warfighter by providing seamless coverage using its own generated power separate from the power grid,” said Navy Cmdr. Renae Renken, commander, DLA Distribution Sigonella, Italy. “We now are a more agile and flexible workforce using this new energy conscious technology that provides greater energy independence in a constantly evolving combat environment.”
