NIGP 29095: Wind Electrical Generating Systems and Accessories

NIGP 29095 Wind Electrical Generating Systems And Accessories is an Item code covering the design, procurement, installation, and maintenance of wind turbine systems for distributed energy resource deployment by state and local public bodies. State and local governments soliciting under this code are acquiring complete wind energy solutions—from microturbines rated at 5 kilowatts or higher through large-scale wind assets in the 40–50 megawatt range—paired with engineering design, permitting, equipment procurement, construction specification writing, and long-term operations and maintenance contracts. The issuing bodies include municipal utilities (the City of Pasadena Department of Water and Power), county energy procurement offices (Harris County, Texas), special-purpose authorities (the Georgia World Congress Center Authority for auxiliary systems), and universities (the University of Southern Mississippi). Work under this code spans both small-scale rooftop installations on public facilities and utility-scale renewable energy portfolios structured through long-term power purchase agreements, with equipment required to meet UL-listing standards, International Building Code compliance, National Electric Code requirements, and grid-interconnection standards such as UL1741SB and IEEE 1547.

Recent activity concentrates in Texas and California, with supporting procurement in Georgia and Mississippi. The City of Pasadena issued RFP 2026RFP0129 for design, engineering, permitting, equipment procurement, and three-year maintenance (with optional one-year extensions to five years total) of a 5-kilowatt-minimum rooftop wind microturbine on a municipally owned building, with proposals due July 7, 2026, and evaluation weighted toward proposed solution (25%), cost (20%), project viability and technical strength (25%), developer experience (10%), and project management (10%), with pass/fail local-business and certified small- or micro-business preferences. Harris County, Texas issued RFP 260057 soliciting 80–100 megawatts of solar and 40–50 megawatts of wind power through long-term power purchase agreements (minimum fifteen years) within ERCOT territory, with a single-vendor or multiple-vendor award anticipated and proposals due June 1, 2026, evaluated on company strength and experience (10%), contracting provisions (10%), pricing (40%), and product structure and attributes (40%). The Georgia World Congress Center Authority solicited planning and design services for an Electrical Systems Replacement Master Plan including electrical distribution assessment across a 3.9-million-square-foot convention center and associated facilities, with master planning completion expected within six months and proposals due April 22, 2026.
