Variable Frequency Drives (VFD) Replacement Phase 3 (DBB)

The Port of Seattle will replace 125 aging Robicon variable frequency drives (VFDs) with new equipment as part of Phase 3 of its VFD Replacement initiative. This effort aims to upgrade outdated infrastructure to ensure system reliability and improve operational efficiency across aviation facilities and infrastructure. The new VFDs will be fully integrated with the Port’s Direct Digital Controller (DDC) system to enable real-time energy usage monitoring, output control readings, and efficiency tracking, enhancing the Port’s ability to manage power consumption and maintain optimal performance. The scope includes all necessary wiring, testing, commissioning, and installation of associated equipment required to deliver a fully functional and synchronized system. The work falls under NAICS code 238210 and is managed by the Aviation Facilities & Infrastructure division, with technical oversight from Project Manager Sharon Miick and primary point of contact Yanet Maldonado. Although the solicitation number and set-aside details are not specified, the forecast was posted on July 31, 2026, signaling upcoming procurement activities. The project is critical for modernizing the Port’s electrical infrastructure and supporting long-term sustainability goals through precise control and monitoring of motor-driven systems. All work must be performed on-site at the Port’s facilities, with full accountability for system integration, performance validation, and operational readiness upon completion.
