Affinity Power Systems LLC is a for-profit limited liability company headquartered in Houston, Texas, that has been registered as a federal contractor with SAM.gov since January 2016. The company specializes in providing electrical and power system equipment, installation services, and technical support to federal maritime agencies, with a particular focus on the U.S. Coast Guard. Affinity Power Systems serves as an original equipment manufacturer and integrator of complex power and control systems for naval vessels, leveraging deep expertise in switchboard procurement, generator systems, and propulsion monitoring infrastructure.

The company has executed numerous federal prime contracts and delivery orders with the U.S. Coast Guard, the Maritime Administration, the Department of the Navy, and the U.S. Army Corps of Engineers.

Affinity Power Systems has provided technical representative services for commissioning, troubleshooting, operational training, and maintenance support across multiple vessel platforms. The company has also supplied switchboards, onboarding parts kits, diesel generator sets, machinery control system upgrades, and alarm monitoring system repairs. Recent delivery orders include a December 2025 award valued at $216,263.23 from the Coast Guard for switchboard installation on the USCGC Campbell and a November 2025 award of $133,031.76 for technical representative services on the USCGC Legare. Notably, all federal contracts awarded to Affinity Power Systems have been issued without small business set-aside designations, reflecting its status as a full-service prime contractor capable of independent performance.

Affinity Power Systems LLC currently holds two primary Indefinite Delivery Contracts with the U.S. Coast Guard. The first is a single-award IDC valued at $3,615,655.78, awarded on September 27, 2023, with an ultimate completion date of September 26, 2029, for procuring switchboards for the service's 270 medium endurance cutters as part of the Coast Guard's Service Life Extension Program. Under this vehicle, the company has issued multiple delivery orders for technical representative services, troubleshooting, and system support. The second IDC, valued at $1,761,824.89 and designated as a total small business set-aside, was awarded on February 13, 2023, though it expired on February 12, 2023, for modifying, replacing, repairing, and maintaining existing ship propulsion monitor and control systems for nine 140-foot WTGB class Coast Guard cutters. Under this contract, the company executed delivery orders for onsite services, machinery control system upgrades, and grooming activities valued up to $983,107.50. Both IDVs reflect the Coast Guard's confidence in Affinity Power Systems' technical capabilities and position the company as a critical long-term vendor for maritime electrical infrastructure modernization across the service's cutter fleet.
