UNSPSC 26131610: Bypass stacks

UNSPSC 26131610 Bypass stacks is a Commodity code, but the recent state and local opportunities tagged under it involve solar and renewable energy equipment and maintenance rather than bypass stacks in the traditional industrial sense. State and local governments are procuring solar photovoltaic inverters, optimizers, and related equipment; design and engineering services for distributed energy resources; and comprehensive maintenance and repair services for solar installations. The issuing bodies include cities (Pasadena, Dallas, Madison, South Fulton), counties (DeKalb, Eastern Municipal Water District in Riverside County), and state procurement cooperative vehicles (South Dakota through Sourcewell). Work ranges from one-time equipment procurements and design-build projects to indefinite delivery/indefinite quantity standing service agreements for on-call maintenance with tiered response times.

Activity is concentrated in California (Pasadena, Riverside County, Dallas in Texas) and Georgia (DeKalb County, South Fulton), with additional recent solicitations in Wisconsin and South Dakota. Representative recent opportunities include the City of Pasadena Department of Water and Power's design and engineering RFP for a 5-kilowatt rooftop wind microturbine (due May 22, 2026, now closed), the City of Dallas ID/IQ bid for solar panel maintenance and repair services (due July 17, 2026), and the City of South Fulton's RFP for licensed solar PV contractors to provide standby response and maintenance with 24/7 availability and tiered response times (due April 9, 2026, now closed). The City of Madison issued an RFQ for six SolarEdge inverters and 2,000 power optimizers (due March 6, 2026, now closed), and South Dakota posted an electrical power generation equipment RFP through Sourcewell (due June 23, 2026, now closed). The code mismatch suggests these solicitations may be tagged incorrectly; bypass stacks themselves do not appear in recent state and local procurement activity under this code.
