NIGP 28511: Capacitors, Motor Starting and Running

NIGP 28511 Capacitors, Motor Starting and Running is an Item code covering discrete capacitor units and bank assemblies that state and local governments procure for electrical system maintenance, distribution infrastructure repair, and motor control applications. Recent solicitations show demand for capacitor banks rated 600–1200 KVAR, metal halide ballast capacitors, and pre-assembled capacitor bank assemblies with integrated controllers and sensors. Austin Energy's October 2026 IFB for capacitor banks and associated parts exemplifies the scope: eight line items covering capacitor banks at specified voltage ratings, transformers, capacitor controllers, current sensors, and neutral current sensors for as-needed stock replenishment. Gwinnett County Parks and Recreation similarly procures approximately 200 capacitor units annually for ballast applications. Issuing bodies include municipal utilities (Austin Energy), county parks departments (Gwinnett County), and independent school districts (Northside ISD), reflecting distributed procurement across utility operations, facilities maintenance, and infrastructure support functions.

Activity concentrates in Texas and Georgia based on recent postings. Austin Energy's IFB (due October 27, 2026) requires deliveries within two calendar days to two warehouse locations and mandates 95% on-time performance; the 24-month initial contract with three one-year extension options establishes a framework for recurring supply. Gwinnett County's June 2026 competitive quote for ballasts and capacitors (approximately $0 estimated annual spend disclosed) spans four one-year renewal options on firm pricing, with samples requested at vendor expense. Northside ISD's July 2026 IFB for electrical equipment, parts, and services (replacing an expiring contract) enforces vendor response or loss of future business; specific capacitor volumes are not disclosed. Manufacturers supplying under these codes must demonstrate five years' experience in distribution capacitor or ballast manufacture and maintain local or rapid-response inventory to meet same-day or two-day delivery windows. Local business and small business preferences apply across these jurisdictions, with Austin Energy offering up to 5% discount for contracts under $500,000 and Gwinnett County using lowest-responsive-quote evaluation.
