New Sunshine Substation Power Transformer

The City of Gallup, New Mexico is seeking to procure a power transformer for the New Sunshine Substation project, with the primary objective of replacing the existing substation and enhancing electrical distribution system reliability. The procurement involves a single 115 kV - 7.62/13.2 kV three-phase delta-wye connected power transformer with specific technical requirements, including ratings of 15/20/25 MVA and a load tap changer (LTC). Approved manufacturers include ABB/Hitachi, SPX Waukesha, Delta-Star Transformers, and other US-based manufacturers, with strict requirements that transformers and related components be sourced, manufactured, and tested in the United States. The Invitation to Bid (ITB #2024-ITB-008) was released on June 14, 2024, with a deadline for questions on August 2, 2024, and a bid submission deadline of August 27, 2024, at 2:00 pm. Bids must be submitted electronically through the OpenGov eProcurement Portal, with evaluation criteria including comprehensive technical specifications, performance metrics, testing requirements, and compliance with ANSI/IEEE C57 standards and NEMA specifications.

The procurement appears to have no specific set-aside designations for disadvantaged enterprises. The transformer must meet stringent performance standards, including operation at 7,000 feet elevation, temperatures ranging from -40F to 115F, and specific loss rates and efficiency metrics. The warranty shall be a minimum of five years after energization or 66 months after shipment, with detailed requirements for technical performance and quality assurance. While no specific incumbent vendor is mentioned, the bid documents include extensive appendices requiring vendors to provide a comprehensive history of similar transformer deliveries, including references from owners of comparable units over the past five years. The bid is subject to sales tax at 8.0625%, and the transformer is intended to serve a utility-scale distribution facility with potential for low-voltage side load transfer operations. Though a specific budget range is not explicitly stated, the comprehensive technical specifications and multiple appendices suggest a significant capital investment for this critical infrastructure upgrade.
