What criteria do utilities consider when selecting a power transformer supplier?

Utilities evaluate technical compliance with IEC/IEEE standards, proven reliability, loss performance, total cost of ownership, manufacturing capacity, and delivery time. They assess service support, spare parts availability, testing facilities, and previous project performance. Quality certifications, warranty terms, and experience with similar voltage and MVA classes are critical. Environmental and safety practices, including oil containment and fire behavior, also influence supplier selection, alongside commercial factors like price and financing options.
