NIGP 07550: Oil Analysis and Diagnostic Equipment

NIGP 07550 Oil Analysis and Diagnostic Equipment, an Item code, encompasses laboratory testing services and diagnostic equipment for electrical insulating fluids and transformer oils at electric utilities, municipal power systems, and other oil-filled electrical infrastructure. State and local governments procure annual insulating oil testing programs that include dissolved gas analysis, furan analysis, moisture testing, PCB analysis, transformer fault interpretation, and condition assessment performed to IEEE C57.104 and IEC standards, typically paired with online sample management systems, data integration capabilities, and engineering consultation on fleet trending and maintenance recommendations.

Electric utilities and municipal power boards represent the dominant issuing bodies under this code, with Lubbock Power & Light in Texas and Keys Energy Services (City of Key West, Florida) appearing as repeat buyers in recent solicitations. Lubbock Power & Light issued RFP 713126ELD in June 2026 (due July 22, 2026) seeking annual insulating oil testing laboratory services for approximately 20 substations and 150 pieces of oil-filled equipment, requiring offerors to hold ISO/IEC 17025 accreditation, five years of documented utility experience, and Laboratory Information Management System capabilities compatible with the Delta-X TOA4 transformer oil database. Keys Energy Services issued two overlapping RFPs (1026 posted April 6, 2026, due April 17, 2026; and 0426 posted April 13, 2026, due February 23, 2026) for three-year electrical insulating oil testing contracts covering 28 power transformer main tank units, 13 load tap changer compartment units, and 10 voltage regulator units, each with two optional one-year renewals. Recent activity concentrates in Texas and Florida, with Lubbock Power & Light in West Texas and Keys Energy Services in the Florida Keys representing the most recent and detailed solicitations. Beyond these electric utility procurements, a small Illinois state purchase (CMS 26416CMSBOPM4B51183, posted March 2026) for two 12-ton vehicle lifts and a Georgia county RFP (Worth County PE77201NONST2026000000016, posted February 2026) for a four-post vehicle lift appear under this code number but reflect equipment procurement rather than oil analysis services; the alignment of these solicitations to NIGP 07550 suggests possible taxonomy variation across issuing jurisdictions.
