Department of Defense signs $133 million deal for its largest base


The Defense Logistics Agency Energy has awarded Ameresco with a contract to improve energy resiliency at a military facility Joint Base San Antonio in Texas.

The $133.5 million contract includes the development of a microgrid and rollout of energy efficiency measures to reduce energy use in 900 buildings across five military locations.

The five locations include Lackland Air Force Base, Fort Sam Houston, Randolph Air Force Base, Kelly Field Annex, Camp Bullis and Medina Annex.

The project will use $2.7 million in funding secured from the Facilities Sustainment Restoration and Modernisation programme.

The microgrid will comprise 20MW of onsite solar PV, 4MW of gas-fired backup generation and 4MW/8MWh of battery storage.

Energy and water conservation measures are expected to help reduce use by 24% annually, with onsite energy generation reducing energy costs on the main grid. The contract will result in $8.7 million in annual energy savings.

The ESPC will provide for HVAC management control systems, over 2 million gallons of thermal energy storage, new LED lighting, and building envelope improvements. More than 140,00 LED lighting systems will be installed across JBSA.

Construction is scheduled to complete during the summer of 2021.
