UNSPSC 15111512: Compressed natural gas CNG

A gaseous by-product of oil used as fuel. CNG is composed of methane gas in a compressed form generally at 3,000 PSI to store as many cubic meters in the cylinders in order to provide greater autonomy to the vehicle.

UNSPSC 15111512 Compressed natural gas CNG (Commodity) covers state and local procurement of natural gas supply, delivery, and fueling-station operations — not just the commodity itself but the full suite of services around acquiring, transporting, and dispensing CNG to municipal fleets and facilities. Recent solicitations show jurisdictions buying compressed-gas fueling-station operation and maintenance (OCTA's three-station CNG facility in California, $2.181 million over three years; DeKalb County's two-station preventive-maintenance contract in Georgia); CNG-powered refuse collection trucks (City of Olathe, Kansas, two new roll-off units); and direct natural gas supply to county facilities and school districts across the Southeast. The issuing-body mix spans transit authorities (Orange County Transportation Authority), county governments (Rockland County, Hillsborough County, DeKalb County, Bartow County), school districts (Fayette County Public Schools, Forsyth County Schools, Carroll County Schools, Newton County Schools, Murray County Board of Education), municipalities (City of Norwich, City of Santa Monica, City of Leesburg), and special-purpose utilities (Norwich Public Utilities). School districts are the dominant repeat buyer, appearing in over half the recent opportunities seeking fixed-price commodity supply contracts for heating and facility operations.

Geographic activity concentrates in the Southeast—particularly Georgia (multiple county and school-district procurements) and Florida (OCTA, Hillsborough County, Escambia County, Marion County)—with notable activity in the Northeast (Rockland County, New York; Norwich, Connecticut) and scattered instances in the Midwest and West (Kansas, California, Texas, Albuquerque). Representative recent opportunities include the Orange County Transportation Authority's RFP for CNG Fueling Station Operation & Maintenance (posted July 8, 2026, due July 8, 2026, three-year contract $2.181 million, Federal Transit Administration funded, mandatory pre-proposal conference June 2) and Rockland County's sealed-bid cooperative purchase of interruptible natural gas supply for county and community-college accounts (RFB RFBRC2026041, posted July 10, 2026, due July 29, 2026 at 11:30 a.m. EST). School-district natural gas supply contracts typically run 12 months (April to March or July to June) with fixed pricing benchmarked to NYMEX Henry Hub rates on specified dates, require Certified Marketer status through Atlanta Gas Light, and include monthly usage reporting; recent examples are Fayette County Public Schools (RFQ posted June 10, due June 23) and Forsyth County Schools (RFQ posted March 9, due March 17). No set-aside designations appear in the recent postings, though some contracts require proof of experience, insurance, and compliance with E-Verify and federal procurement standards where federal funding is present.
