The U.S. hydropower industry is a vibrant, growing part of the American energy economy. As the first-ever U.S. Hydropower Supply Chain Snapshot shows, the hydro industry supports a thriving domestic supply chain that benefits regions and communities across the country.

The U.S. Hydropower Supply Chain Snapshot features more than 2,500 companies in the non-federal hydro supply chain. Those companies include small, medium and large firms, and range from project developers to construction companies; architecture and engineering firms to electricians; and component manufacturers to biologists.

Much of the hydro industry’s growth has come through the modernization of existing facilities; the conversion of non-powered dams; and the deployment of pumped storage, hydrokinetic, and conduit technologies. It’s an industry that is ready to grow even more.

Hydro’s supply chain also stretches across the country — and in places not usually associated with clean energy, like the South and the Rust Belt.

The Snapshot clearly shows that smart, targeted federal policies to incentivize investment have paid dividends around the country. And it shows what’s at risk if Congress fails to provide a stable, predictable policy environment for renewable energy moving forward.

The U.S. Hydropower Supply Chain Snapshot was developed using data from a representative sampling of NHA’s 200 members, which includes project developers, generators, and major suppliers in the non-federal system. It is not a comprehensive listing of every company in the hydro supply chain. Moving forward, NHA will be working with additional members to expand the number of companies represented.
