North Substation Power Transformer

The City of Leesburg, Florida is requesting proposals for the design, manufacture, supply, factory testing, delivery, installation, and commissioning of one 67–13,090 kV power transformer for the North Substation, with proposals due August 19, 2026 at 11:00 p.m.

The transformer must be manufactured within the continental bounds of the United States and delivered to 2435 Marcella Way in Leesburg, Florida. It shall be a three-phase, oil-immersed unit rated 18/24/30/36.6 KNAN/KNAF (55C) KNAF (65C) with continuous self-cooled and forced-air cooling capability, equipped with a Reinhausen RMV-II Load Tap Changer with TAPCON 250 controller, lightning arresters, and two stages of fan cooling. The specification requires a Schweitzer Engineering Laboratories SEL-2414 transformer monitor and SEL-2533 annunciator, positive pressurizing nitrogen system, and comprehensive factory and field testing per IEEE standards including routine tests, dielectric tests, impulse tests, temperature rise tests, and dissolved gas analysis. A manufacturer's field service engineer must supervise on-site assembly, oil filling, and testing. Target installation is Fall 2028.

Minimum qualifications include at least five years of recent relevant experience, four professional references from projects completed within the past five years, demonstrated financial stability through bank documentation, and required insurance coverage: Commercial General Liability minimum $1,000,000 per occurrence, Business Automobile Liability minimum $1,000,000 per occurrence, and Workers' Compensation as required by Florida law. Vendors must be registered with E-Verify and possess all necessary federal, state, and local licenses and certifications.

Evaluation is based on a 100-point scale: Management and Personnel Qualifications (10 points), Relevant Experience of Firm (25 points), Approach to Delivery of Services (40 points), Financial Compensation (20 points), and Required Forms/Documents/Licenses (5 points). The City will evaluate bids on a twenty-year cost-of-ownership basis using a formula incorporating unit cost, no-load losses at $3,623 per kW, and load losses at $486 per kW for the 18.0 MVA rating. A five-year warranty is required, extending either five years from energization or 66 months from delivery, whichever is longer. Questions are due August 10, 2026 at 10:00 a.m., with addenda issued by August 13, 2026 at 4:30 p.m. The Evaluation Committee meets August 27, 2026 at 10:00 a.m. via Zoom.
