About ESL Power Systems, Inc.
ESL Power Systems, Inc., a self-certified small disadvantaged business based in Corona, California, manufactures specialized electrical equipment and power distribution systems for maritime and naval operations as a prime contractor on full-and-open federal purchase orders and definitive contracts. The company is a for-profit Subchapter S Corporation registered in SAM.gov since 2007, competing entirely as a prime (100% of recent awards) without subcontract engagement, and does not utilize small business set-asides despite its small disadvantaged business designation — all recent awards carry no set-aside designation.
ESL Power Systems concentrates on electrical component manufacturing across NAICS categories dominated by miscellaneous electrical equipment and component manufacturing (22 awards) and motor and generator manufacturing (7 awards), with PSC coding reflecting connectors, electrical (20 awards), electrical control equipment (4 awards), and miscellaneous power distribution equipment (4 awards). Concrete capability work includes a $237.8 thousand definitive contract with Naval Facilities Engineering Command for shore power equipment at Navy Base Guam (August 2023), a $184.5 thousand firm fixed-price purchase order from the Department of the Navy for a manual bus transfer unit at Naval Submarine Support Facility (January 2026), a $180.4 thousand purchase order from the Navy for a manual bus transfer unit with April 2025 completion (July 2024), a $83.9 thousand Coast Guard purchase order for cutter line insulation monitor cabinets at Base Guam (September 2025), and a $65.8 thousand NAVFAC purchase order for portable power units at Norfolk, Virginia (July 2024).
Customer concentration aligns tightly with maritime and naval agencies. The Department of Homeland Security Coast Guard accounts for 22 awards worth $568 thousand combined potential value; the Department of the Navy Naval Sea Systems Command holds 8 awards worth $1.1 million; and the Department of the Navy itself carries 3 awards worth $441 thousand. These three customers represent 74% of recent award count and 86% of combined potential value, with additional work flowing to NOAA and the Smithsonian Institution. ESL Power Systems places three task orders under Federal Supply Schedule GS07F0180W.
Activity has declined from historical levels — three awards in 2021 to one in 2025 and one in 2026 — with only one award (combined potential value $184 thousand) reaching ultimate completion inside the next twenty-four months. The vendor's $3.3 million combined potential value across all recent awards, with $2.7 million (84%) already obligated, reflects a highly order-driven, low-volume manufacturing business anchored to repeat naval and Coast Guard component needs rather than large programmatic vehicles. ESL Power Systems operates entirely from its Corona, California facility or subordinate naval installations (Norfolk, Base Guam, Naval Submarine Support Facility) where work is performed.
