Energy Resilience Partners Wins $100 Million Lake City Ammunition Plant Microgrid Contract

Energy Resilience Partners LLC of Belcourt, North Dakota, won a $99.7 million firm-fixed-price contract to construct a microgrid and combined heat and power system at the Lake City Army Ammunition Plant in Independence, Missouri. The U.S. Army Corps of Engineers’ Louisville District awarded the project under the Energy Resilience and Conservation Investment Program. The work is intended to provide the plant with on-site electricity and heat and the ability to operate during a utility-grid outage. Completion is estimated for July 5, 2029.

Lake City Army Ammunition Plant Microgrid and Combined Heat and Power Details

Energy Resilience Partners will build a 15-megawatt combined heat and power plant powered by two 7.5-megawatt combustion turbines capable of using natural gas or propane. The project description calls for heat-recovery steam generators, supplemental duct firing, a black-start diesel generator and a backup propane storage and supply system. The contractor will connect the new equipment to Lake City’s existing natural-gas, steam, condensate and water systems so it can operate alongside the central heating plant.

The electrical work includes distribution equipment and underground duct banks linking the new generation system to the plant’s infrastructure. Microgrid controls will connect with two existing substations at four points of common coupling. They are designed to support operation alongside the utility, independent operation during an outage, black starts, load shedding to balance supply and demand, and resynchronization when grid power returns. A new control room will be located in the central heating plant.

The project also encompasses communications, cybersecurity, site improvements, demolition, air permitting and full commissioning. An amendment to the construction documents identifies work on 12.47-kilovolt distribution feeders, existing substations and the microgrid control system. The solicitation establishes a construction period of 1,014 calendar days following notice to proceed.

Lake City Energy and Ammunition Production Background

Lake City is a government-owned, contractor-operated plant that produces and accepts small-caliber ammunition and operates a regional munitions test center, according to the Army Sustainment Command’s installation profile. The Defense Department’s project budget justification identified reliance on local electric and natural-gas utilities, without backup electricity or heat, as a vulnerability during outages. It listed $80.1 million for the Lake City microgrid and backup-power project at that stage of planning.

The energy project comes as the Army modernizes ammunition production at the plant. The Army broke ground in February 2025 on a separate 6.8mm ammunition facility supporting the Next Generation Squad Weapon program and reported in August 2026 that the building had reached the weather-tight “dry-in” milestone. That work illustrates the industrial setting in which the new power and heat systems will operate.

Award and Contractor Background

The construction procurement was open to all bidders, with a HUBZone price-evaluation preference, and drew two bids, according to the award notice and solicitation notice. The Corps issued the solicitation in April 2026. Before the award, it had estimated the construction magnitude at $25 million to $100 million, toward the upper end of that range.

This award was disclosed by the DoW in its daily press release. Additional contract details will be available on HigherGov in approximately 90 days under W912QR26CA040 after the contract is formally disclosed by the government.
