Webbers Falls Excitation System

This project includes the replacement of the excitation systems (including the Potential Transformers) for all units at Powerhouse. The installation and commissioning of Unit 1 will be dependent on the availability of the unit, which is currently out of service due to issues with the speed gear. The Contractor will be responsible for designing and manufacturing the new excitation system equipment, delivering to the site, removing the existing equipment, installing the new equipment, and commissioning the new system. They will also perform model validation testing and reporting as listed above. The Hydroelectric Design Center (HDC) will provide submittal reviews, factory visit(s) to witness factory testing, and commissioning support to include determining draft settings for the excitation systems. The government will be responsible for landing all new cable (except for the AC cables from the bus tap to the Potential Transformers and the DC cables from the exciter to the brush rigging) to all external locations within the powerhouse, external to the new exciter and Potential Transformer cubicles.
