CWS manufactures transformers, generators, uninterruptible power supply systems, HVAC units, power distribution equipment, and related electrical components for federal facility operations and infrastructure replacement. Representative prime work includes a $330,864 delivery order from DISA for shorebox filters supporting Middle East operations with an ultimate completion date in 2029; a $316,805 Air Force order for transformer and four-way cooper switch products; a $423,917 FEMA delivery order for portable resistive load banks to distribution centers in Atlanta and Tracy; and a $291,586.75 ASPR order for electrical cables and trauma packs. Work spans HVAC installation at multiple Western Area Power Administration substations in the Midwest (four purchase orders totaling roughly $100 thousand awarded June 2026), UPS battery replacement and power supply delivery to civilian agencies, and generator procurement and installation across Air Force, Army, Coast Guard, and National Park Service facilities.

Customer concentration is diffuse across 67 agencies. The top five funding agencies by award count account for 26% of recent awards: Western Area Power Administration (10 awards, $277 thousand combined potential value), Department of State Bureau of Overseas Building Operations (7 awards, $213 thousand), Air National Guard (7 awards, $325 thousand), Bureau of Reclamation (6 awards, $245 thousand), and Coast Guard (6 awards, $597 thousand). By potential-value share, Coast Guard leads at $597 thousand across six awards, followed by Air Force components (seven Air Force and Air Force Materiel Command awards totaling $973 thousand) and Washington Headquarters Service ($343 thousand across three awards). No single customer dominates the portfolio; the top five by value represent 14% of combined potential.
