UNSPSC 39122100: Electrical transmission and distribution equipment

Equipment, components and supplies associated with utility transmission and distribution functions

UNSPSC 39122100 Electrical transmission and distribution equipment is a Class code covering replacement and upgrade work on electrical infrastructure components that state and local governments operate to support utility delivery, facility operations, and public amenities. Recent solicitations show state and local buyers purchasing tank switches, reclosers, transformers, variable frequency drives, and related apparatus—equipment that manages voltage levels and load distribution across electrical networks. The work ranges from single-unit replacements at water treatment plants and military facilities to multi-unit distribution system upgrades at parks and transit centers. Issuing bodies span state departments (Maryland Environmental Service, Florida Department of Military Affairs, Washington State Department of Ecology), municipal utilities (Wellesley Municipal Light Plant, Norwich Public Utilities), counties (Gwinnett County, Riverside County, DeKalb County), cities (Phoenix, Torrington, Tampa), transit authorities (Greater Orlando Aviation Authority, Park City Municipal Corporation), and special-purpose districts (Eastern Municipal Water District, Tohopekaliga Water Authority). Repeat buyers include Wellesley Municipal Light Plant, which has posted five separate bids for tank switches and reclosers since late April 2026, and Riverside County, with multiple VFD procurements at water facilities.

Geographic activity concentrates in Florida, California, Massachusetts, Georgia, Arizona, Connecticut, and Washington. Representative recent opportunities include the State of Florida Department of Military Affairs ITB for a $1.8 million Camp Blanding primary power distribution system upgrade (sealed bids due August 26, 2026, with mandatory pre-bid meetings and 150-day substantial completion), Maryland Environmental Service IFB for Janes Island State Park electrical system replacement and EV charging infrastructure (sealed bids due August 7, 2026, with 15% MBE participation goal), Washington State Department of Ecology IFB for electrical maintenance services at its Lacey headquarters (bids due July 20, 2026, set-aside for small business or veteran-owned firms with $150,000 or less estimated value), and Wellesley Municipal Light Plant RFQ for six 15kV 600A three-phase reclosers (bids due July 14, 2026). The code also captures equipment procurement—EMWD's call for three 500HP VFDs (RFB due April 30, 2026), Greater Orlando Aviation Authority's VFD repair and replacement services contract (RFP due March 31, 2026), and the City of Phoenix Water Services' five-year VFD supply framework (IFB due September 15, 2025). Construction services are frequently paired with equipment installation; prevailing wage and performance bonds typically apply. Evaluation often weights experience with similar projects, compliance with technical specifications, and competitive pricing; MBE and veteran-owned business participation goals appear regularly.
