About the company
Mader Supply, LLC, a woman-owned small business based in North Highlands, California, supplies specialized electrical equipment and safety gear to federal power and natural-resource agencies as a prime contractor, operating exclusively through purchase orders and delivery orders with no recurring parent contracts or vehicles.
Mader Supply competes predominantly full-and-open; none of its recent awards carry a set-aside designation except for one Total Small Business category awarded by the Western Area Power Administration in 2024 and another in 2025. The vendor is structured as a for-profit limited liability company and holds no SBA 8(a), HUBZone, SDVOSB, or other special small-business certifications beyond its woman-owned small business status.
Customer concentration is extremely narrow. The Department of Energy's Western Area Power Administration accounts for 100% of the vendor's dollar footprint—six awards totaling $312 thousand of the $332 thousand combined potential value across all awards in the source window. The remaining two awards came from the Department of the Interior's Fish and Wildlife Service Region 1 (one purchase order for $13,747 to supply an emergency generator to the Coleman National Fish Hatchery, awarded September 16, 2026) and Region 8 (one purchase order for $7 thousand in electrical transfer switch repairs, awarded May 5, 2025). WAPA awards include a $47.3 thousand firm fixed-price purchase order placed February 24, 2025 for Travis Pattern brand electrical conductor compression deadends for warehouse stock, a $46.9 thousand purchase order awarded March 20, 2024 for Corona Shield Rings for the Olinda-Tracy Deadend Insulator Project, and a $14.1 thousand delivery order from March 10, 2022 for DMC Power personal protective grounding stirrups.
Activity is sporadic—two awards in 2019, one in 2022, one in 2024, two in 2025, and one in 2026—with only one award (the $13.7 thousand Fish and Wildlife generator contract concluding December 31, 2026) reaching completion inside the next twenty-four months. The vendor places no work as a subcontractor. Work is performed against an indefinite delivery contract (89503019DWA000010) under which two task orders generated $55 thousand in combined potential value, with the balance issued as standalone purchase orders. NAICS concentration reflects electrical hardware supply and repair work, dominated by current-carrying wiring device manufacturing, electrical contractor services, and capacitor and transformer manufacturing across product categories spanning connectors, electrical insulators and insulating materials, and miscellaneous electric power and distribution equipment.
