NIGP 91221: Construction, Energy Related (All Types)

NIGP 91221 Construction, Energy Related (All Types) is an Item code covering design, construction, and infrastructure work on energy-related facilities—including utility plants, water systems, electrical infrastructure, renewable energy installations, and related mechanical and civil components—that state and local governments solicit across dozens of jurisdictions and project types. Recent opportunities span county departments and municipal utilities purchasing well drilling and agricultural water infrastructure (Boulder County Parks and Open Space), utility-scale water treatment facilities and reclaimed water pumping stations (Cities of Palm Bay and Apopka), electrical substation construction and transmission line work (Kissimmee Utility Authority, Keys Energy Services), fleet electrification infrastructure including EV charger installation (Cities of Thousand Oaks and Lompoc, Orange County Transportation Authority), district energy and chilled water systems (University of Texas at Austin), and smaller distributed generation and backup power systems (Indian River County, Augusta University). Issuing bodies include county departments, municipal utilities, city public works agencies, water districts, special districts, regional transit authorities, and public universities; Orange County, Florida and several Texas municipalities are repeat issuers. Work is solicited through RFPs, RFQs, and ITBs with response deadlines typically 30–90 days out; many projects involve preconstruction or design-build delivery models with staged fee structures.

Geographic activity concentrates in Florida (Orange County, Palm Bay, Apopka, Keys Energy), Texas (Tucson, Cibolo, Lawrenceville, Austin), Georgia (Dalton-Whitfield, DeKalb County, Tybee Island, South Fulton), and California (Thousand Oaks, Lompoc), with scattered opportunities in Colorado (Boulder County), Arizona (Tucson), and Virginia (Fairfax County).
