NIGP 28587: Transformers, Power, Electric Sub-Station

NIGP 28587 Transformers, Power, Electric Sub-Station is an Item code covering procurement of power transformers and high-voltage testing equipment by utilities, municipalities, and special-purpose districts. State and local governments are actively buying transformer units rated from single-phase distribution transformers (25–75 kVA) through large three-phase substation transformers (20–36.6 MVA), pad-mounted and pole-mounted equipment, transformer repair and rewinding services, and precision high-voltage diagnostic and testing modules. Recent solicitations span multiple issuing bodies including municipal electric utilities (Keys Energy Services, Kissimmee Utility Authority, City of Leesburg), county governments (Palm Beach County, Fairfax County), cities (City of Palo Alto, City of Hayward, City of College Park), water and wastewater districts (Eastern Municipal Water District, Hayward Water Resource Recovery Facility), and school districts (Northside Independent School District). Procurement activity is driven by system upgrades, routine maintenance and replacement cycles, emergency repairs, and operational diagnostic needs. The scope includes transformer design and manufacturing to specification, factory and field testing, oil filling with non-toxic dielectric fluids (Envirotemp FR3 or mineral oil variants), installation and supervision, and comprehensive warranty coverage.

Geographic activity spans Florida (Kissimmee, Leesburg, Key West), California (Palo Alto, Hayward), Virginia (Fairfax County), Georgia (College Park), Texas (San Antonio), and other states. Representative recent solicitations include the City of Leesburg requesting design, manufacture, and installation of one 18–36.6 KNAN/KNAF power transformer with Load Tap Changer and Schweitzer monitoring via RFP26017LK (proposals due August 19, 2026); City of Hayward requesting complete repair and restoration of an existing Schneider Electric transformer with new copper windings and comprehensive testing via RFQ 27005 (quotations due October 28, 2026); City of Palo Alto pre-qualifying vendors for procurement of six 20/26/34 MVA substation transformers rated 115/60–12.47Y/7.2kV via PQ197857 (questionnaire due September 11, 2026); Keys Energy Services requesting distribution transformers in multiple configurations (pole-mounted and pad-mounted, 25–1,000 kVA) via solicitation 2026 (proposals due October 16, 2026); Kissimmee Utility Authority requesting precision high-voltage testing modules (OMICRON CP TD12) via IFB26046JG (bids due September 22, 2026); and Fairfax County issuing RFP 2000004461 to establish one or more contracts for electrical and emergency power systems installation and replacement (proposals due October 16, 2026).
