About this file
This solicitation is for a firm fixed-price construction contract to rehabilitate turbine generator units at Old Hickory Power Plant in Hendersonville, Tennessee. The scope of work includes rewinding and upgrading generators for units 1, 2 and 3 to increase maximum output to 45 megawatts. It also involves replacing the Kaplan turbine runners for the same units to support the new load and increase rated output to 61,600 horsepower. For unit 4, the generator was previously rewound but the turbine runner replacement is optional. Additional work comprises inspecting and refurbishing all mechanical support systems, replacing worn components, and upgrading systems to current standards. Electrical work consists of generator rewinds, model verification, condition monitoring systems and relay/control upgrades. The term for the first unit is estimated at two years for testing, design and fabrication, followed by 18-month installations for the remaining units. The estimated contract value is between $25-100 million. The question period closes in May 2022 and site visits are scheduled for May 5th, with request forms due in advance. The solicitation is issued by the Nashville District of the U.S. Army Corps of Engineers.
