NIGP 28511: Capacitors, Motor Starting and Running

NIGP 28511 Capacitors, Motor Starting and Running is an Item code describing electrical starting and running capacitors that state and local governments procure as components for HVAC systems, lighting ballast assemblies, motor equipment, and related electrical infrastructure across facilities. Recent solicitations show school districts, counties, and transit authorities buying capacitors as part of broader electrical equipment, parts, and supplies contracts rather than as standalone line items, though some jurisdictions issue dedicated RFQs for capacitors paired with ballasts on annual supply agreements. The work involves furnishing specified capacitor models or approved equivalents, often with firm unit pricing and multi-year renewal options, and delivering to designated government facilities on an FOB destination basis with shipping and handling included in quoted prices.

Gwinnett County, Georgia and Northside Independent School District in San Antonio, Texas have posted recent opportunities under or related to this code. Gwinnett County Parks and Recreation issued an RFQ on June 2, 2026 (due June 12, 2026) for approximately 200 capacitor units annually on an annual contract with four one-year renewal options, specifying Aerovox Z74S5232NN or approved equivalent models, with questions due June 8, 2026. Northside Independent School District posted IFB 2025098 on June 8, 2026 (due July 1, 2026) for electrical equipment, parts, supplies, rentals, repairs, and services, replacing expiring contract 2025-100; the District requires all incumbent and prospective vendors to respond or risk losing future business, with all proposals including shipping and handling to the District's San Antonio location. Activity under this code is limited, with geographic concentration in Texas and Georgia among the recent opportunities posted.
