About Stonewin Capital LP
Stonewin Capital LP, a United Kingdom-based global fuel supply trading company headquartered in Edinburgh, delivers petroleum products to the Department of Defense as a prime contractor, competing in the open federal marketplace without small business set-asides across a single-award Indefinite Delivery Contract worth $68.573 million with the Defense Logistics Agency Energy.
Stonewin Capital LP operates through its Stonewin SIA Division to supply automotive gasoline, diesel fuel, marine gas oil, biodiesel, ethanol, and aviation turbine fuel. The company's federal work is almost entirely concentrated on the Defense Logistics Agency Energy's Post Camps and Stations Purchase Program 1.8M, which procures fuel for U.S. military installations primarily in Germany and other international locations. The parent Indefinite Delivery Contract SPE60525D1252, awarded November 1, 2024, through August 30, 2028, is structured as a fixed-price requirements contract with economic price adjustment authority. Representative delivery orders in 2026 include fuel oil burner supply valued at $861,337.26 (January 27, 2026), marine gas oil supplies ranging from $33,831 to $1,055,762 (multiple awards through Miami, Florida and Great Britain), diesel fuel orders between $10,000 and $143,000, and automotive gasoline at $18,186 to $35,545. All delivery orders employ fixed-price pricing with economic price adjustment mechanisms to manage volatile fuel commodity markets while maintaining pricing certainty for the government.
Customer concentration is singular: DLA Energy accounts for 4,319 of 4,322 total awards (100% of potential value at $527.7 million combined), with only three small naval and Army awards totaling $811 thousand rounding out the portfolio. The vendor receives hundreds of delivery orders annually under its parent IDC—1,701 task orders under SPE60519D1250 carrying $33.9 million, 478 under SPE60519D9415 with $16.8 million, and 349 under SPE60525D1252 with $13 million. Activity volume peaked in 2022 (344 awards) and has remained in the 220–290 range annually through 2026; year-to-date 2026 shows 184 awards as of April 15, 2026. The five-year combined obligated value is $251.4 million of a $528.5 million combined potential value ceiling (48% drawn). Stonewin Capital LP operates without subcontractors and holds no documented federal vehicle positions other than its single-award IDC with DLA Energy. The vendor is a for-profit partnership with a named foreign-owned subsidiary, Stonewin LLC, and competes exclusively in full-and-open fuel procurement with no set-aside reserve participation.
