AWARD: $54.3M 10MW GENERATION PLANT WITH MICROGRID CONTROLS
ADVANCING ENERGY RESILIENCE AND SECURITY
On 31 October 2025, the U.S. Army Corps of Engineers awarded David Boland, Inc. the firm-fixed-price contract for the 10MW Generation Plant with Microgrid Controls project at Fort Stewart, Georgia. The contract, valued at $54.3 million, will be executed over approximately three years.
This project is part of the Energy Resilience and Conservation Investment Program (ERCIP), which funds initiatives that improve energy resilience, contribute to mission assurance, save energy, and reduce the Department of Defense’s energy costs.
The scope of work includes the construction of a 10-megawatt (10MW) power station consisting of ten 1-megawatt (1MW) natural gas generator sets, which will be integrated with the existing Fort Stewart substation. An advanced microgrid control system will be installed to increase energy resilience and promote sustainability. This system will also incorporate existing natural gas and solar photovoltaic generation assets.
The project includes providing paralleling switchgear for the control and paralleling of the generator sets and connection of the redundant feeders to the substation, along with potential transformers to meet relaying and metering requirements. Protective relaying will include source protection, feeder protection, generation protection, and synchronization. The existing substation will be modified by upgrading relays on the circuit breakers to synchronize with the generator sets. Existing feeder breakers will also be upgraded to provide operational compatibility with the new switchgear and main service. Approximately 7,500 linear feet of underground natural gas piping will be constructed to serve the generation plant.
The new microgrid control system will match mission-critical facility loads with available supply, operating both in parallel and islanded modes. It will include transfer switches, interface relays, microgrid controllers, and fiber optic communication connections. The system will connect to an existing solar photovoltaic array, enabling approximately 10 megawatts (10MW) of existing photovoltaic capacity to integrate into the microgrid without causing frequency fluctuations or voltage drops during conditions such as increasing cloud cover. The microgrid will also have the capability to incorporate additional solar photovoltaic capacity and future battery energy storage systems to meet expanding demands.
Situated approximately 40 miles southwest of Savannah, Fort Stewart is a key U.S. Army installation in southeastern Georgia and the largest by land area east of the Mississippi River. It is home to the 3rd Infantry Division—one of the Army’s most storied combat divisions—which serves as a subordinate unit of the XVIII Airborne Corps under the U.S. Army Forces Command (FORSCOM).
