UNSPSC 26111601: Diesel generators

UNSPSC 26111601 Diesel generators, a Commodity code, encompasses standby and emergency backup power units that state and local governments purchase as fixed installations, trailer-mounted mobile units, or components of larger integrated power systems. Recent solicitations show two primary buying streams: procurement of new generator equipment—typically 125 kW to 2,500 kW diesel units paired with automatic transfer switches, fuel systems, and installation labor—and maintenance, repair, and emergency service contracts covering existing generator fleets. School boards, county facilities, city utilities, water treatment plants, fire departments, and emergency operations centers drive demand. The scope ranges from definite-quantity purchases of equipment (such as the School Board of Volusia County's five 125 kW generator-with-trailer ITB or Beaufort County's 350 kW whole-building installation) to turnkey projects bundling procurement, design, installation, commissioning, and operator training (City of Waxahachie's 250 kW senior center generator system or Hillsborough County's 1,500 kW wastewater facility project estimated at $4.7 million). Maintenance contracts command significant activity: the City of Phoenix issued a five-year IFB for preventive maintenance, load bank testing, and 24/7 emergency response on over 300 industrial generators across 35 kW to 3,500 kW capacity; Orange County, California's IFB covers as-needed service and repairs across 33 Sheriff facilities with 24/7 response and one-hour callback; and Seminole County, Florida sought multiple vendors through RFP for routine and emergency service on approximately 230 generators across three years.

Issuing bodies span state departments, county commissioners, municipalities, special districts, transit and water authorities, and higher education institutions. Counties and cities dominate recent activity, with repeat buyers including Beaufort County (two generator installation solicitations posted within days), Henry County Georgia (annual maintenance RFP), Columbia County Georgia (emergency backup generators at three facilities), and state procurement offices for dedicated facilities. Geographic activity concentrates in Florida, Georgia, California, Texas, South Carolina, and Arizona in recent postings, with additional opportunities in Maryland, Colorado, Utah, and Wisconsin. Representative recent opportunities include the City of Phoenix's five-year preventive-maintenance contract (IFB-26-0395, offers due October 9, 2026) covering industrial generators and automatic transfer switches; Orange County, California's emergency service and repair IFB (0603146703MB, bids due November 12, 2026) with 5% OCLSB/DVBE preference; Hillsborough County's 1,500 kW generator procurement and installation at a reclaimed water facility (IFB2600406, bids due November 18, 2026) with 5% SBE subcontractor participation goal; City of Waxahachie's 250 kW turnkey senior center generator system (ITB202691, sealed bids October 22, 2026); and Beaufort County's 350 kW administration building installation (IFB111026, bids due November 10, 2026) with mandatory S/MBE participation requirements. Contract vehicles commonly include firm fixed-price installation, lump-sum bids, hourly labor rates plus materials for service, and multi-year maintenance agreements structured as as-needed release orders.
