About N C Power Systems CO.
N C Power Systems CO., doing business as N C Engine Power Co., is a small disadvantaged business and division of Harnish Group Inc. that provides emergency diesel generator and automatic transfer switch leasing and related services to federal agencies as a prime contractor (99% of awards), competing predominantly in full-and-open federal procurements without set-aside designations. The company is headquartered in Tukwila, Washington, and operates across primary NAICS categories of equipment rental and leasing, motor and generator manufacturing, and ship repair support, with electrical power distribution equipment leasing (PSC code) representing the dominant service category.
N C Power Systems' federal footprint is heavily concentrated with the Department of the Navy. The Naval Sea Systems Command (NAVSEA) accounts for 311 awards totaling $24.1 million in combined potential value—roughly 55% of the vendor's total award count and 55% of its dollar base. The U.S. Coast Guard represents the second-largest customer at 65 awards valued at $15.2 million. Together, NAVSEA and the Coast Guard cover 76% of awards by count and 90% of potential value, leaving limited diversification across 27 other federal agencies. The gap between award count and dollar concentration reflects NAVSEA's role as an anchor customer with both numerous small task orders and several larger individual contracts.
The vendor's primary vehicle is a single-award Indefinite Delivery Vehicle (IDV) with NAVSEA, contract N4523A22D1304, valued at $4.8 million and running through August 2027. This vehicle has generated 86 task orders to date. An older NAVSEA IDV (N4523A17D0004) has produced 106 task orders and carries a $4.2 million ceiling. The Coast Guard operates its own IDIQ for engine overhaul work that has yielded 18 task orders valued at $5.7 million combined. Additional smaller vehicles with Military Sealift Command and other Navy offices round out the portfolio. Across these vehicles, N C Power Systems issues delivery orders and purchase orders for 250 kW to 1,000 kW diesel generator leases, automatic transfer switch rentals, diesel engine overhauls, and related maintenance and parts support.
Representative contracts demonstrate the scale and scope. A firm fixed-price delivery order from NAVSEA on March 3, 2026, for a 250 kW emergency diesel generator lease carries a ceiling of $55,425.29 with completion in March 2027. Another February 2026 delivery order for a 1,000 kW generator lease was valued at $181,780 for a one-year performance period at Bremerton Naval Shipyard. A September 2023 option-year purchase order for ten 100 kW towable diesel generators totaled $1.638 million with completion in 2028, supporting the Puget Sound Naval Shipyard. N C Power Systems also performs diesel engine overhaul work; a September 2023 purchase order for service and repair of a Caterpillar 3508 diesel engine was valued at $116,981.51 with May 2025 completion.
The vendor subcontracts on ship maintenance and modernization work. Since 2025, N C Power Systems has supplied generator rentals to Vigor Marine LLC on U.S. Navy ship modernization projects: USS Kidd (DDG 100) depot work, USS Gabrielle Giffords (LCS 10) modernization (both through Vigor), and USS Sampson (DDG 102) 5E2 EMAV transformer rentals (through Delphinus Engineering). These sub-awards involve large capacity generators—Caterpillar XQ1500 (1,500 kW) and XQ2000 (2 MW) models—leased on multi-month performance periods for shipyard and fleet support work.
Activity has remained relatively stable. The source captures 494 total awards across a 39-year span, with recent-year performance showing 22 awards in 2022, 29 in 2023, 32 in 2024, 25 in 2025, and 14 through early 2026. Combined obligated dollars ($46.7 million) exceed combined potential value ($43.8 million) by 7%, indicating the vendor is executing against ceiling values across its portfolio. Recompete exposure is limited: only 12 awards face completion within the next twenty-four months, carrying combined potential value of $806 thousand. The two major NAVSEA IDVs—the older N4523A17D0004 and current N4523A22D1304—together anchor $9 million in ceiling value across 192 task orders and represent N C Power Systems' most material contract vehicles through 2027.
