UNSPSC 39121025: Buck boost transformer

UNSPSC 39121025 Buck boost transformer is a Commodity code tracking the procurement of voltage-regulation transformers and related electrical distribution equipment by state and local governments. State and local buyers use this code for step-up and step-down transformer installations, pad-mounted distribution transformers, substation transformers, and integrated power systems combining transformers with switchgear, generators, and related control infrastructure. Recent solicitations show a mix of large-scale utility infrastructure projects and smaller spot purchases by municipalities, utilities, school districts, and transit authorities. The issuing bodies include city utilities departments (Cumming, Georgia; Albany, Georgia; Fairburn, Georgia), cooperative electric utilities (Lubbock Power & Light, Texas), state agencies (Florida Department of Agriculture and Consumer Services), school districts (Northside Independent School District, Texas; Pinellas County Schools, Florida), departments of criminal justice (Texas), and higher education institutions (University of Mississippi; Texas State Technical College). Work ranges from turnkey generator and switchgear installations with multi-year engineering and commissioning (Cumming's 2,500 kW diesel generator project with 3,750 kVA transformers) to large power transformers for grid substations (Lubbock's 50 MVA step-up transformer for Oliver Substation) to underground distribution systems with pad-mount transformers (Fairburn's 12.47 kV loop-feed installation) to spot purchases of standard pad-mount units (Albany's 100 kVA and 167 kVA transformers).

Recent activity concentrates in the South and Southwest, with Georgia (Cumming, Albany, Fairburn) and Texas (Lubbock, San Antonio, Rosharon, Dallas) showing the most recent solicitations. The City of Cumming's PWPF Generator and Switchgear Project (RFP, due August 7, 2026) exemplifies large-scale infrastructure work, requiring design, permitting, permitting, procurement of a 3,750 kVA step-up transformer, switchgear, and 60/90/100% design phases before construction. Lubbock Power & Light's RFP for a 50 MVA transformer for Oliver Substation (due August 5, 2026) reflects utility procurement of standard grid equipment with turnkey delivery and on-site testing. The City of Fairburn's IFB for Ferndale Phase III Underground Power (due July 22, 2026) calls for 25 kV rated primary cable, pad-mount transformer rubber goods, and associated distribution equipment on a 12.47 kV system. The City of Albany's sealed-bid procurement for twelve 100 kVA and three 167 kVA pad-mount transformers (due June 8, 2026) represents routine utility supply work with 30-day delivery expectations and DBE participation encouraged. Florida's IFB for 115 kV substation steel structures (BP-8, due July 21, 2026) and the Texas Department of Criminal Justice's RFP for a 4160-volt electrical power distribution system replacement at Memorial Unit (due June 8, 2026, estimated budget $6,806,200) indicate both structural substation components and large integrated electrical infrastructure are tagged to this code, though the TDCJ project spans broader electrical work beyond transformers alone. The City of Austin's RFP for three-phase pad-mounted distribution transformers (due April 21, 2026) anticipates 285 units annually across 20 configurations, representing high-volume as-needed purchasing.
