UNSPSC 81102400: Electrical power transmission engineering

UNSPSC 81102400 Electrical power transmission engineering is a Class code spanning the design, engineering, and commissioning services for electrical generation, distribution, and transmission infrastructure that state and local governments procure for water treatment plants, wastewater facilities, utility systems, and public works infrastructure. Recent solicitations show state and local agencies buying preliminary and final design work, commissioning services, operation and maintenance contracts, and construction management for electrical system upgrades, power distribution improvements, cogeneration assets, battery storage, microgrids, and PFAS treatment facility electrical improvements. The County of Orange, California—through its Public Works Department, Flood Control District, and affiliated utilities—is the dominant repeat buyer in the recent opportunity set, issuing multiple task-order RFQs for power generation and distribution engineering services, roadway and bikeway electrical components, and airport electrical materials testing and inspection.

Geographic activity concentrates in California (Orange County in particular) and Florida, with secondary activity in Georgia, Texas, Mississippi, North Carolina, and Rhode Island. Representative recent opportunities include the County of Orange's RFQ for Power Generation, Distribution Engineering & Commissioning Services (Solicitation 0803025703REA, RFQ, due July 3, 2026) seeking A-E firms with ten-year track records in cogeneration, microgrids, photovoltaic systems, and EV charging infrastructure; Collier County, Florida's RPS for South County Water Reclamation Facility Treatment Technology & Flow Management Improvements (Solicitation 268635, due March 23, 2026) requiring comprehensive electrical design and commissioning for a plant capacity expansion from 16 MGD to 21.1 MGD; and Columbus Water Works' CMAR RFP for PFAS Treatment Improvements (Solicitation PE33100NONST2026000000010, due June 4, 2026) covering preconstruction and construction electrical services across two Georgia water facilities. These procurements typically structure compensation as time-and-materials with hourly classification rates, require three-year California or local business experience and state PE licensure, and award through RFQ-based Qualified Vendor Lists with no guaranteed work volumes and three-year initial terms.
