Specifications for Purchase of Autotransformer

Keys Energy Services (KEYS), a municipal electric utility in Key West, Florida, is soliciting bids for KEYS Bid 11-25, a procurement for a new 138/69kV autotransformer to be installed at the US1 Substation. The project requires a three-phase, three-winding, oil-immersed autotransformer with specific technical specifications, including a wye-wye-delta connection, 75/100/125 MVA capacity, and a 65C average winding rise. Bidders can submit proposals for three options: a base bid with a full stainless steel tank, an alternate bid with a mild steel tank and stainless steel top, and a second alternate with an all mild steel tank. The bid will be evaluated using a Total Owning Cost (TOC) formula considering purchase price, no-load losses, and load losses. Proposals are due on May 21, 2025, at 10:00 AM, with an electronic submission requirement, and bidders can participate in a virtual bid opening meeting. The project timeline spans from March 2025 to May 2027, with a contract award anticipated on June 18, 2025, and a Notice to Proceed by June 30, 2025.

The procurement requires North American manufacturing and mandates specific technical standards, including compliance with ANSI, IEEE, and NEMA regulations. There are no explicit set-aside designations for disadvantaged enterprises mentioned in the documentation. Bidders must submit a 5% bid bond or certified check and provide comprehensive documentation, including insurance and performance statements. The transformer requires a standard 18-month warranty, with an optional three-year extended warranty available. Delivery is subject to specific constraints, including loading restrictions that limit installation to winter months and potential transportation challenges in the Florida Keys. While a specific budget range is not explicitly stated, the comprehensive technical specifications and evaluation criteria suggest a significant capital investment. A U.S.-based service partner is acceptable for field service, and KEYS will assist with coordination and potential barge offloading at the Florida Keys Aqueduct facility if bridge restrictions necessitate alternative delivery methods.
