NIGP 92666: Oil/Water Separator Inspection and Testing Services

NIGP 92666 Oil/Water Separator Inspection and Testing Services, an Item code, encompasses laboratory testing and condition assessment of insulating oils used in electrical equipment—primarily oil-filled power transformers, load tap changers, and voltage regulators operated by municipal utilities and public power authorities. State and local buyers under this code procure comprehensive oil sampling, ASTM-compliant laboratory analysis, dissolved gas analysis, furan testing, moisture evaluation, PCB screening, fleet trending, and engineering interpretation tied to transformer diagnostics and maintenance planning. Deliverables typically include IATA-compliant sample collection kits, written maintenance reports with hot oil reclamation guidance, reference tag installation on sample valves, and internet-accessible data portals holding multi-year test histories. Issuing bodies are primarily municipal and regional electric utility boards and power authorities—government-owned generation, transmission, and distribution operators rather than general-purpose municipalities. Work is performed on-site at substations and power facilities during regular business hours, with annual sampling cycles synchronized to utility maintenance schedules and contract renewal periods.

Recent activity concentrates in Florida and Texas. The Utility Board of the City of Key West, Florida (Keys Energy Services) posted two overlapping RFPs for electrical insulating oil testing in September 2026, both seeking three-year base contracts with two optional one-year renewals to serve approximately 51 oil-filled units (28 power transformer main tanks, 13 load tap changer compartments, 10 voltage regulators) with annual sampling in January; sealed proposals for the first were due February 20, 2026 and for the second April 17, 2026. Lubbock Power & Light (Texas) issued an RFP on June 18, 2026 for annual insulating oil testing across approximately 20 substations with proposals due July 22, 2026, emphasizing ISO/IEC 17025-accredited laboratories with five years of utility experience, Laboratory Information Management System capability, and compatibility with Delta-X TOA4 transformer database systems. Minimum contract insurance requirements run $2 million Commercial General Liability and $1 million Business Automobile Policy across Texas and Florida opportunities. No set-aside designations or disadvantaged-enterprise restrictions appear in recent solicitations.
