U.S. Hydropower Supply Chain Manufacturing Locations, 2025

Overview

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: 

• System for Award Management (SAM.gov) (for components purchases by federal hydropower owners)

• 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)
