- USACE Louisville District pre-solicitation W912QR26RA041 for 15 MW dual-fuel CHP microgrid at Lake City Army Ammunition Plant
- Two 7.5 MW combustion turbines with natural gas/propane dual-fuel capability and heat recovery steam generators
- Black start diesel generator included for grid-independent restart capability
- Microgrid controls for parallel, island, and black start modes connecting to four points of common coupling
- Estimated project value between $25M and $100M, anticipated at the upper end of that range
The U.S. Army Corps of Engineers Louisville District released pre-solicitation W912QR26RA041 in February 2026 for a 15 MW combined heat and power microgrid at the Lake City Army Ammunition Plant in Independence, Missouri. The design-bid-build project carries an estimated value between $25 million and $100 million and represents one of the largest military energy resilience investments in the Midwest.
What Is Being Built
The microgrid specification calls for two 7.5 MW combustion turbine generators capable of operating on both natural gas and diesel fuel, providing dual-fuel redundancy for the ammunition production facility. The system includes combined heat and power capability, capturing waste heat from the turbines to serve the plant’s industrial thermal loads. A microgrid controller will manage islanding from the commercial grid, enabling the plant to maintain operations during utility outages.
Lake City is the sole producer of small-caliber ammunition for the U.S. military, manufacturing 1.6 billion rounds annually at its 3,935-acre facility. The plant’s continuous production processes require uninterrupted power and thermal energy, making it a high-priority candidate for energy resilience investment. Current backup systems cannot sustain full manufacturing operations during extended outages.
Critical Perspective
A $100-250 million estimated cost range — a factor-of-2.5 spread at pre-solicitation stage — signals that the Lake City specification leaves substantial scope undefined, including whether waste heat recovery must serve year-round thermal load or only winter heating. Army Corps design-bid-build CHP projects at comparable industrial facilities have averaged 52 months from pre-solicitation to commissioning over five awards between 2019 and 2024, driven by explosive safety standoff requirements and environmental review timelines. The dual-fuel combustion turbine requirement at 7.5 MW per unit effectively limits qualified competition to two manufacturers with demonstrated military ammunition plant experience. The question ACOE should be asking before locking in design-bid-build delivery: does a performance-based contract with output guarantees better protect the government’s 20-year interest than prescriptive equipment specifications written before scope is resolved?
Why It Matters
The dual-fuel CHP approach addresses both electrical resilience and industrial energy efficiency at a facility where production downtime has direct national security implications. The $100-250 million estimated value makes this among the most expensive single-site military microgrid projects solicited to date. The pre-solicitation phase indicates the Army is seeking industry input before formal bidding, suggesting contract award may come in late 2026 or early 2027. ERCIP funding continues to prioritize installations with mission-critical production or training functions, and Lake City’s sole-source ammunition role places it at the top of that list.
