UNSPSC 26131610: Bypass stacks

UNSPSC 26131610 Bypass stacks (Commodity) shows sparse recent state and local activity, with posted opportunities appearing tangential to the code's nominal scope. The source records no solicitations explicitly requesting bypass stacks, flue gas ductwork, or related exhaust components. The code's abstract definition and the work actually being solicited diverge materially. State and local governments posting under this code in recent months have instead sought solar installation, electrical power systems, microgrids, wind energy systems, water well drilling with solar pumps, waste-to-energy facility design-build-operate-maintain services, and solar equipment maintenance contracts. None of these opportunities reference bypass stacks, stack components, or exhaust gas treatment infrastructure as a primary deliverable or specification line item.

Activity is geographically scattered across Georgia (Tybee Island, Decatur, DeKalb County), Virginia (Fairfax County), Colorado (Boulder County), California (Riverside County), Florida (Palm Beach County), and South Dakota, with no concentration in any single state or region. Issuing bodies span municipalities (Tybee Island, Pasadena, Decatur, Dallas), counties (Fairfax, Boulder, DeKalb, Palm Beach, Riverside), a state procurement vehicle (South Dakota via Sourcewell), a water utility (Eastern Municipal Water District), and a special-purpose authority (Solid Waste Authority of Palm Beach County). Recent notices include an RFP for a 42 kilowatt solar array at the Tybee Island Marine Science Center (due November 3, 2026), a resolicitation by Fairfax County for electrical and emergency power systems installation and replacement (due October 16, 2026), and a design-engineering RFP by the City of Decatur for a 170 kW solar photovoltaic system with battery storage and DC fast charging (due October 13, 2026). The code shows little relevant recent activity for business development focus.
