NIGP 99259: Oil Field Equipment Testing Services

NIGP 99259 Oil Field Equipment Testing Services is an Item code. State and local governments procure laboratory testing and diagnostic services for oil-filled electrical equipment—including insulating-fluid analysis, dissolved gas analysis, furan analysis, moisture testing, PCB testing, and transformer fault interpretation—performed by U.S.-based laboratories holding ISO/IEC 17025 accreditation and serving multiple electric utility customers. The work involves condition assessment of power transformers, load tap changers, breakers, and related equipment in compliance with IEEE C57.104 and IEC diagnostic methodologies, often paired with data integration into utility-specific database systems and engineering support. Electric utilities drive procurement under this code; Lubbock Power & Light (LP&L), a Texas-based municipal utility, has posted at least one RFP for annual oil testing laboratory services covering approximately 150 pieces of oil-filled equipment across roughly 20 substations.

Recent activity is concentrated in Texas, with Lubbock Power & Light posting an RFP for annual insulating oil testing and laboratory services with a response deadline of July 22, 2026, weighted toward technical qualifications and utility experience (35%), laboratory information management and data integration (25%), and engineering support capabilities (20%), with pricing (15%) and proposal completeness (5%) making up the remainder. The same utility also solicited decommissioning services for used oil-filled non-PCB electrical equipment via RFP #7120-26-ELD, due February 19, 2026. A separate Maine Department of Administrative and Financial Services RFQ for photo-ionization detectors and associated equipment posted June 16, 2026, with a July 7, 2026 response deadline, represents testing instrumentation rather than the laboratory analysis services that dominate the code's application at electric utilities.
