This map showcases the newly developed ORNL hydropower supply chain database. The goal of this newly developed ORNL hydropower supply chain database is to increase the knowledge of manufacturers/suppliers domestically to all hydropower owners and developers. A comprehensive database of component suppliers can translate in time and cost savings for hydropower plant owners and developers navigating the component procurement process. Additionally, details on manufacturing locations can help hydropower owners in meeting domestic content goals and requirements for their facilities. Components investigated include: bearings, castings/forgings, cranes/hoists, exciters, gates, generators, governors, penstocks, switchgears, transformers, trashracks, turbines, and valves.
Sources of data include:
- List of exhibitors at Clean Currents 2023
- Water Power Magazine Buyer’s Guide
- Existing Hydropower Assets (EHA) Unit Database (data on turbine manufacturers for units installed since 2010)
- Putsche et al. (2024). “Hydropower Supply Chain Gap Analysis” (for manufacturing locations of castings and forgings)
- Nguyen et al. (2022). “Electric Grid Supply Chain Review: Large Power Transformers and High Voltage Direct Current Systems” (for manufacturing locations of large power transformers)
- System for Award Management (SAM.gov) (for components purchases by federal hydropower owners)

U.S. Hydropower Supply Chain Manufacturing Locations, 2025
This dataset lists manufacturing locations for the following list of hydropower plant components: castings/forgings, turbines, generators, governors, exciters, bearings, valves, penstocks, gates, cranes, switchgear, and transformers. The data includes manufacturing locations as listed by the companies in their websites or other public sources. Some companies have multiple manufacturing locations. In some cases, it was not possible to verify if components relevant to the hydropower industry are produced at all the locations.
