About the company
Engineered Mechanical Systems Inc., Ems Division, is a minority-owned, woman-owned, Native American-owned, small disadvantaged business based in Chattanooga, Tennessee, that manufactures heavy industrial equipment and performs fabrication, rewinding, and engineering services for federal hydroelectric and power infrastructure projects exclusively as a subcontractor. The company holds DOT-certified Disadvantaged Business Enterprise (DBE) status and competes entirely under small-business set-asides; it carries no prime federal contract awards in the available source data.
EMS Division operates as a fabrication and maintenance specialist within the federal hydroelectric and civil engineering construction sector. Across nine recent sub awards, all extended by GE Renewables US LLC between April 2024 and June 2025, EMS Division has delivered generator turbine runner replacement work, stator coil manufacturing and repair, generator rewinding services, and associated concrete and structural modifications at federal dam facilities. The largest-scope engagement, awarded June 2025, covers replacement of main unit generator turbine runners in units 1–14 at McNary Dam Powerhouse in Umatilla, Oregon, plus rewinding of three main unit generators. Earlier sub work under the same prime includes full unit rewinding (Unit 4), stator frame repairs, custom stacking tooling, and engineering support for stator coil sets. All identified work falls under NAICS 333611 (turbine and turbine generator set units manufacturing) or related heavy civil engineering construction codes.
Customer concentration is narrow and focused on federal dam operations. Nine awards cover three distinct agencies: the Department of the Army Corps of Engineers Engineering District Mobile (6 awards), the Department of Energy Bonneville Power Administration (2 awards), and the Department of the Army Corps of Engineers (1 award), with the Corps' Mobile District accounting for two-thirds of award volume. Combined obligated dollars across all nine sub awards total $371 thousand, representing a small-dollar footprint typical of component fabrication and field service work tied to specific capital projects rather than recurring task-order volume.
Activity trajectory shows declining recent momentum. Eight sub awards were issued in 2024; only one award appears in 2025 year-to-date. All work flows through GE Renewables as the prime contractor; no independent prime vehicles, GWACs, BPAs, or parent IDIQs appear in the award record. EMS Division's federal footprint is tightly scoped to subcontract roles supporting hydroelectric equipment replacement and maintenance, driven by capital project cycles at Corps of Engineers and Bonneville Power Administration facilities rather than standing procurement demand.
