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.
