NIGP Code 285-39 — Generators, Portable and Stationary (Including Parts and Transfer Switches) — is a standardized State, Local, and Education (SLED) procurement classification within Class 285 — Electrical Equipment and Supplies of the National Institute of Governmental Purchasing (NIGP) Commodity/Services Code taxonomy. Across all 50 states, over 33 state central purchasing offices and thousands of county governments, municipal utilities, public university systems, transit authorities, and K-12 school districts obligate approximately $1.7 Billion annually under NIGP 285-39, generating 460+ Bids active Invitations for Bid (IFBs), Requests for Proposals (RFPs), and informal quote requests each year. The NIGP taxonomy uses a hierarchical structure where the 3-digit Class (285) identifies the broad commodity or service family (Electrical Equipment and Supplies) and the 5-digit Class-Item code (285-39) pinpoints the specific commodity (power generation) deliverable. When state and municipal buyers post solicitations on portals such as Texas ESBD & Water Districts, Florida MFMP, California Cal eProcure (PSPS Resiliency), and Louisiana LaPAC, automated bid invitations are dispatched exclusively to vendors who have added NIGP Class 285 and Item 285-39 to their supplier registration profiles.
