The U.S. Army Corps of Engineers awarded Dominion Energy subsidiary Dominion Privatization Texas a $61.5-million contract to build the Phantom Warrior Microgrid at Fort Hood, Texas.
The hybrid system will combine 3 MW of natural gas-fired generation, a 1.5-MW solar parking canopy and a 1-MW battery energy storage system to support critical facilities for at least 14 days during a grid outage.
The microgrid will serve about 2.9 MW of connected load and use automated switching to isolate portions of Fort Hood’s electrical distribution system, with completion scheduled for early May 2029.
Defense budget documents submitted in 2022 carried a $31.5-million project cost for Phantom Warrior; Dominion was later identified as the intended sole-source contractor under authority for certain military energy-resilience projects with privatized utilities.
Phantom Warrior is Dominion’s second major Fort Hood microgrid award this year, while the Army is planning at least three additional installation microgrids targeted for fiscal 2030.

The U.S. Army Corps of Engineers awarded Dominion Energy subsidiary Dominion Privatization Texas a $61.5-million contract Oct. 30 to build a hybrid microgrid at Fort Hood, Texas, designed to keep critical facilities operating for at least 14 days during a grid outage.

The Phantom Warrior Microgrid will combine 3 MW of natural gas-fired reciprocating generation, a 1.5-MW solar photovoltaic parking canopy and a 1-MW battery energy storage system with automated switching and microgrid controls.

The system will serve approximately 2.9 MW of connected load, including 2.12 MW classified as critical and 0.79 MW of noncritical load. The generation and storage equipment will connect to the installation’s 12.47-kV electrical distribution system and is scheduled for completion in early May 2029.

Automated switches will allow portions of two distribution feeders to separate from the installation’s larger electrical system during an outage. Natural gas engines will provide dispatchable generation and establish the voltage and frequency reference for the solar array. During normal grid conditions, the engines are to remain disconnected while solar generation offsets electrical demand. The solar array will be installed on canopies above parking areas behind Building 1001.

The project has been in the military construction pipeline for several years. Defense budget documents submitted in 2022 carried a $31.5-million project cost for a Phantom Warrior microgrid combining photovoltaic, natural gas and battery generation at Fort Hood.

Dominion was identified as the intended sole-source contractor when the Corps announced the procurement in May 2025, using authority Congress provided for certain Energy Resilience and Conservation Investment Program projects at military installations with privatized utility systems.

Phantom Warrior is the second major Fort Hood microgrid contract Dominion was awarded this year. In March, the company received a separate $16.65-million contract for a microgrid serving the installation’s Network Enterprise Center, with completion scheduled for October 2028.

The Army is planning at least three more. Projects targeted for fiscal 2030 include a natural gas distributed-generation system designed to power 32 mission-critical and essential facilities from the Clarke Road substation for at least 14 days, along with separate systems at Yoakum-DeFrenn Army Heliport and North Fort Hood.
