This solicitation is for a firm fixed-price construction contract to rehabilitate three turbine generator units at the Old Hickory Power Plant in Hendersonville, Tennessee. The Nashville District U.S. Army Corps of Engineers seeks to increase the maximum output of units 1, 2, and 3 to 45 megawatts by rewinding their generators and replacing their turbine runners. Unit 4's generator was previously rewound in 2021. The estimated value of the contract is between $25 million and $100 million.

The scope of work involves model testing, design, and fabrication for the first unit over two years followed by 18-month installation periods for subsequent units. Electrical work centers on rewinding and restacking generators for units 1-3. Mechanical work consists of replacing turbine runners for units 1-3 and optionally for unit 4, as well as inspecting, refurbishing, and upgrading various mechanical support systems. A pre-bid site visit will be held on May 5, 2022, with request forms due May 2 for foreign nationals and May 6 for U.S. citizens. The question and answer period is open through the ProjNet website.
