Daeryun E&S Co., LTD.

Daeryun E&S Co., LTD., a Seoul-based, for-profit utility services provider, supplies natural gas to U.S. Army facilities in South Korea as a prime contractor under a single-award Indefinite Delivery Contract with the Department of the Army Installation Management Command Korean Region (IMCOM-Korea), with no set-aside designation. The company holds a narrow, mission-critical customer base — 100% of its 29 federal awards and $71.8 million in combined potential value derive from IMCOM-Korea — and operates exclusively in South Korea to support energy infrastructure at U.S. military installations, principally United States Army Garrison Casey.

Daeryun E&S has held a SAM registration since June 2012 and operates under a 10-year IDC valued at $28.0 million (awarded December 1, 2022, extending through November 30, 2032). The contract structure uses firm fixed-price delivery orders. Since the IDC inception, IMCOM-Korea has issued nine delivery orders ranging from $3,795 for gas meter replacement to $1.74 million for natural gas supply. Recent representative work includes a $1.74 million firm fixed-price delivery order for natural gas supply to USAG Casey (awarded October 1, 2024; completion June 30, 2025), a $1.03 million delivery order for utility gas supply (awarded November 1, 2025; completion January 31, 2026), and a $33,295 delivery order for utility gas at Camp Casey (awarded February 1, 2026; completion May 31, 2026). All delivery orders maintain no set-aside designation.

Award velocity is flat to declining — three delivery orders in 2022, two each in 2023 and 2024, two in 2025, and one in the first quarter of 2026. The company sits on three parent IDC vehicles: W91QVN13D0006 (17 task orders, $15.5 million combined potential value), W91QVN23D0001 (8 task orders, $5.6 million combined potential value), and W91QVN12D0088 (1 task order, $45 thousand). Work category concentration is complete — all 29 awards fall under NAICS Natural Gas Distribution and PSC Utilities–Gas. Daeryun E&S operates as a prime contractor only; there are no subcontract awards in the source data. Combined dollars obligated across all awards total $21.2 million, representing 29% of the $71.8 million combined potential value, reflecting the firm fixed-price delivery-order structure and multiple contracts still in performance or future execution phases.
