Yesco Co.,Ltd

Yesco Co., Ltd., a South Korea-based for-profit supplier, operates as a prime contractor providing natural gas utility supply to U.S. Army installations in the Pacific region under full-and-open, non-set-aside delivery orders and indefinite delivery contracts. The vendor is not SBA-certified under any program and maintains exclusive focus on a single customer relationship with the Department of the Army Installation Management Command Pacific Region dating to at least 2010.

Yesco's operational footprint is highly concentrated and specialized. The vendor serves only two Army customer entities across 24 total prime awards spanning the past five years, with 23 of 24 awards (98% by count and 100% by potential value) flowing through Department of the Army Installation Management Command Pacific Region. All work falls under PSC Utilities—Gas, with 23 awards classified under NAICS Natural Gas Distribution. The vendor's geographic scope is limited to the Yongsan Main installation in South Korea, where it supplies natural gas for heating and facility operations supporting U.S. military installations. Recent delivery-order work includes a November 1, 2025 award of $161,587 for utility gas supply (ultimate completion January 31, 2026), a July 1, 2025 delivery order of $42,247.01 for utility gas (completion October 31, 2025), and a December 1, 2024 award of $123,619.57 for natural gas supply (completion June 30, 2025).

The vendor holds two principal indefinite delivery contracts with Army IMCOM Pacific Region. The larger vehicle, Indefinite Delivery Contract W91QVN13D0007, carries 14 task orders with $12.7 million combined potential value. The second, Indefinite Delivery Contract W91QVN23D0002, awarded December 1, 2022, carries a ceiling of $4.33 million with ultimate completion November 30, 2032, and has generated six delivery orders totaling approximately $893 thousand to date; this single-award IDC structure provides the framework for all recent delivery orders (2022 onward) against this established supplier relationship. Combined potential value across all 24 awards is $35.7 million, with $25.2 million obligated (71% realization). Activity volume remains flat at one to two awards annually over the past five years, reflecting the stable, steady-state nature of the utility supply requirement rather than growth or decline. The vendor's registration in the System for Award Management dates to December 2010, indicating a long-established operational presence supporting Army logistics in South Korea.
