NIGP 28584: Transformers, Transmission Line Type

NIGP 28584 Transformers, Transmission Line Type, an Item code, covers single-phase and three-phase power distribution transformers procured by state and local utilities, municipalities, and special-purpose water and transit authorities for system upgrades, routine maintenance, emergency repairs, and new service deployment. State and local governments buy distribution-class transformers—overhead single-phase units, underground padmount three-phase assemblies, and voltage regulators—alongside supporting power materials such as conductor, poles, crossarms, and switching cabinets. Issuing bodies include municipal utility departments and special-purpose authorities operating transmission and distribution infrastructure; school districts and transit systems do not appear as active procurers under this code in recent activity. Geographic spread spans Florida, Georgia, and Michigan, with activity concentrated among medium-sized municipal utilities and regional water authorities managing infrastructure replacement and capacity expansion.

Recent opportunities include the City of College Park Power Department's ITB for single-phase overhead transformers, three-phase padmount units, and 50 transformer pads among broader power materials, due August 10, 2026, with local preference of up to 3% available for vendors with a staffed physical location in city limits; the City of Ocala Utility Services' ITB for six 250 KVA distribution regulators (original equipment utility manufacturers only), due November 21, 2026; and the Great Lakes Water Authority's request for bid on the 42-Inch Downriver Transmission Main Loop project in Michigan, due March 13, 2026, which includes construction and equipment procurement with a 3 percent economic equity scoring component favoring vendors with state or local disadvantaged business presence. Transformer and regulator procurement at the utility scale is episodic rather than continuous; activity clusters around multiyear infrastructure modernization cycles and emergency asset replacement, making advance market visibility and relationships with municipal utility procurement offices critical to capture.
