About the company

Written by GovTribe AI ·

Osage Nation Energy Services LLC, doing business as Osage Nation Environmental Solutions, LLC, provides environmental consulting, natural and cultural resources compliance, remediation services, and ecosystem management to the Department of Defense, Army Corps of Engineers, and USDA as a tribally owned, SBA 8(a) certified small disadvantaged business operating exclusively as a prime contractor (100% of recent awards). The vendor is a subsidiary of parent company Osage, LLC, and competes predominantly under 8(a) set-asides (sole source and competitive designations) across defense and civilian environmental work at military installations and federal lands.

Osage Nation Energy Services concentrates its customer base heavily in Department of Defense environmental programs. The top five funding agencies account for 90% of recent awards by count and 94% by combined potential value. The Department of the Army Installation Management Command Southeast Region leads by award frequency (9 awards, $27.1 million combined potential value), anchored by a $7.5 million single-award Competitive 8(a) Indefinite Delivery Contract for natural and cultural resources compliance at Fort Campbell, Kentucky extending through March 2030. The Department of the Army Corps of Engineers Engineering District Mobile ranks second (6 awards, $22.3 million combined potential value), including a $9.9 million 8(a) Sole Source Indefinite Delivery Contract for Army Regional Environmental and Energy Office services awarded in June 2022 with ultimate completion in June 2027. The Department of Agriculture Forest Service Washington Office Acquisitions anchors the largest single dollar commitment: a $50 million multiple-award Blanket Purchase Agreement for Land Management Integrated Resources (LMIR) services with a period of performance through March 2033. Secondary customers include the Department of the Army Corps of Engineers Engineering District Louisville ($9.9 million environmental remediation contract at Jefferson Proving Grounds, Indiana, through June 2030, awarded under 8(a) Sole Source), the Department of Health and Human Services National Institutes of Health Clinical Center ($8.857 million Sole Source definitive contract for a UMI Panorama PET/CT scanner, completed September 2026), and the Department of Interior Bureau of Indian Affairs Southern Plains Region ($256 thousand combined potential value across two awards).

Recent capability work demonstrates portfolio breadth across environmental compliance, endangered species management, and facility support. Osage Nation Energy Services received a $7.713 million 8(a) Sole Source purchase order from ENDIST Fort Worth in August 2026 for environmental services at Hickam Air Force Base, Hawaii through August 2027. The vendor secured a $4.705 million 8(a) Sole Source definitive contract from the Army Southeast Region in July 2025 for endangered species and ecosystem management support at Fort Eisenhower, Georgia extending through July 2029, paired with a $4.088 million 8(a) Sole Source contract for endangered species survey and habitat restoration at the same installation through July 2030. Three non-set-aside Army delivery orders totaling $4.081 million (issued September 2025) support the Chief of Army Reserve's strategic readiness, planning, and environmental quality compliance functions at Fort Liberty, North Carolina and Fort Belvoir, Virginia. A $6.383 million delivery order from the Army Corps of Engineers covers comprehensive environmental services in Pawhuska, Oklahoma (awarded June 2023, ultimate completion July 2026). The Army Corps of Engineers also issued a competitive 8(a) delivery order valued at $1.122 million in April 2026 for natural and cultural resources compliance at Fort Campbell, Kentucky through March 2027, and a second competitive 8(a) delivery order of $824 thousand in July 2025 for the same program through March 2026.

Activity accelerated sharply in 2025 (nine awards) from low volumes in 2022–2024 (one to two awards per year). Within the next twenty-four months, two awards with combined potential value of $8.8 million face ultimate completion and recompete exposure. The vendor holds two primary Indefinite Delivery Contracts: the Fort Campbell Natural Cultural Resources Compliance IDC (Competitive 8(a), $7.5 million ceiling, 2025–2030) and the Army Regional Environmental and Energy Office IDC (8(a) Sole Source, $9.9 million ceiling, 2022–2027). Task orders under these vehicles account for $12.4 million and $1.9 million in combined potential value respectively. The corporate parent, Osage, LLC, operates six named joint-venture subsidiaries (Ones Veloxxity Joint Venture LLC, Ones On Collab Joint Venture LLC, Ones Plexus JV II LLC, Ones Whitetail Joint Venture LLC, Ones Plexus Joint Venture LLC, and Ones WTE JV), all structured as tribally owned, minority-owned small business joint ventures with varying SBA certifications and Department of Transportation Disadvantaged Business Enterprise designations. Combined federal obligations across all awards total $37.8 million against $126.2 million in combined potential value (30% obligation rate).
