NIGP 28539: Generators, Stationary Type (Not Automotive)

NIGP 28539 Generators, Stationary Type (Not Automotive) is an Item code capturing state and local procurement of standby and emergency power systems for fixed facilities—diesel, natural gas, and gasoline units ranging from 20 kilowatts to 800 kilowatts, sold as equipment alone or bundled with installation, automatic transfer switches, fuel systems, and multi-year maintenance contracts.

State and local issuing bodies soliciting under this code span school districts, county governments, cities, water authorities, and special-purpose districts, with significant recent activity concentrated in Florida, Georgia, Texas, and Michigan. Recent solicitations show a mix of one-time capital purchases (generator procurement and turnkey installation) and ongoing service contracts (maintenance, repair, load bank testing, emergency response). School boards in Florida and Michigan are acquiring generators for emergency power at campuses and facilities. County governments across Georgia, Texas, and Florida are replacing aging units at detention facilities, administrative buildings, and fleet maintenance yards. Water utilities in Mississippi, Georgia, and Texas are procuring generators for treatment plants and lift stations. City fire departments, especially in Georgia and Florida, are securing units for station operations and emergency backup. A representative recent opportunity: Beaufort County, South Carolina issued IFB #2024-REQ-010 (due November 10, 2026) for procurement and installation of a 350-kilowatt diesel generator with automatic transfer switch, concrete pad, masonry enclosure, and electrical work at the county administration building—a turnkey scope requiring S/MBE participation. Another: County of Santa Clara Procurement Department released ITB-PRC-FY27-0064 (due November 11, 2026) for generator preventative maintenance, inspection, load bank testing, and emergency repair services across county facilities, requiring C-10 Electrical Contractor licensing and prevailing wages. The City of Phoenix issued IFB-26-0395 (offers due October 9, 2026) for emergency power supply systems preventative maintenance, testing, and repair covering over 300 industrial generators ranging from 35 kilowatts to 3,500 kilowatts across municipal facilities, with a five-year term commencing December 1, 2026, and DBE-N participation mandated. Collier County issued ITB 26-8618 (due March 24, 2026) for generator maintenance and repair services covering portable and stationary units 7 kilowatts to 2,000 kilowatts with 24/7 emergency response, three-year initial term, and approximately $1.5 million in annual county spending historically. Recurring themes include federal or state grant funding (FEMA Hazard Mitigation, GEMA), mandatory prevailing wages on public works, performance and payment bonds at 100 percent of contract value, insurance requirements of $1 million to $2 million general liability, local small-business set-asides and preferences in several states, and tight timelines for both equipment delivery (90 to 120 days) and service response (one to four hours for emergencies).
