NIGP 29095: Wind Electrical Generating Systems and Accessories

NIGP 29095 Wind Electrical Generating Systems And Accessories, an Item code, encompasses the procurement, installation, and maintenance of wind turbine equipment and related electrical infrastructure for renewable energy generation at state and local facilities. State and local governments buying under this code acquire complete wind systems including turbines, inverters, electrical controls, and ancillary equipment, along with the engineering, design, permitting, and long-term maintenance services required to integrate these systems into municipal operations. Recent solicitations show state and local buyers treating wind systems as part of broader distributed energy resource or renewable energy portfolios rather than as standalone commodity purchases, bundling wind procurement with engineering design, interconnection services, and multiyear operations and maintenance agreements.

Harris County, Texas and the City of Pasadena, California have driven recent activity in this code space. Harris County issued an RFP in May 2026 seeking 40–50 megawatts of wind power capacity through long-term power purchase agreements with minimum fifteen-year terms and prepaid pricing structures; the City of Pasadena Department of Water and Power issued an RFP in July 2026 for design, engineering, permitting, and procurement of a 5-kilowatt rooftop wind microturbine with three-year maintenance, with a non-mandatory site walk on April 24, 2026 and a question deadline of May 8, 2026. Harris County's solicitation emphasized ERCOT-located assets, P50 production data, interconnection queue status, and component sourcing transparency, while Pasadena's focused on UL-listed equipment, International Building Code compliance, and fixed all-in pricing including engineering and annual maintenance. Both jurisdictions applied prevailing wage requirements and insurance minimums ($1 million to $2 million in coverage). Geographic activity concentrates in Texas and California, with secondary issuing bodies including counties and municipal utilities in these states. The code sees sporadic activity—mostly RFP-driven renewable procurement programs rather than routine commodity buys—reflecting the capital-intensive, project-specific nature of wind system deployment at the state and local level.
