NIGP 690: Power Generation Equipment, Accessories, and Supplies

NIGP 690 Power Generation Equipment, Accessories, and Supplies is a Class code covering preventative maintenance, inspection, load bank testing, emergency repair services, and equipment supply for generators and associated infrastructure across municipal, county, and regional power systems. State and local governments procure routine generator maintenance—semi-annual inspections, oil changes, filter replacements, and two-hour load testing—as well as emergency repair and replacement services for units ranging from 25 kilowatts to 600 kilowatts. The code also captures specialized power infrastructure work including thyristor stack rebuilds, automatic transfer switch (ATS) installations and replacements, uninterruptible power supply (UPS) system maintenance, and new power transformer procurement and commissioning. Recent solicitations show county facilities, municipal utilities, transit authorities, water reclamation districts, and specialized infrastructure operators (detention centers, hospital campuses) competing for services. The County of Santa Clara, City of Napa, City of Leesburg, Fairfax County, and the Maryland Department of Transportation are repeat buyers in the recent posting window.

Activity spreads across California, Florida, Virginia, Arizona, Connecticut, New York, New Jersey, Michigan, Maryland, and Delaware, with substantial concentration in Florida and California. Representative current opportunities include the County of Santa Clara's ITB for generator preventative maintenance, inspection, load bank testing, and emergency repairs due November 11, 2026; the City of Napa's RFP for comprehensive maintenance and repair of 27 municipal generators across water and fire facilities, with evaluation weighted toward total price (70 points) and qualifications (20 points); the City of Leesburg's RFP for a single 67–13,090 kilovolt power transformer with factory testing and on-site commissioning, proposals due August 26, 2026; and Fairfax County's resolicitation RFP for electrical and emergency power systems installation and/or replacement to establish multiple contracts and expand contractor capacity, proposals due October 16, 2026. The Delaware Department of Energy issued an RFP for low-to-moderate-income solar installation participating contractors on October 15, 2026, establishing a multi-year framework for residential solar work under that same Class. Prevailing wage, bonding, licensing, and insurance requirements are standard; federal compliance including Davis-Bacon, Buy America, and DBE participation goals apply where federal funding is present.
