National Hydropower Day 2025

August 24 is National Hydropower Day! For over 140 years, hydropower has fueled the nation with clean, renewable energy. To collectively recognize hydropower’s contributions to bolstering the nation’s clean energy infrastructure and providing grid resiliency and reliability, we’ve established August 24 as National Hydropower Day.

Because National Hydropower Day falls on a Sunday this year, we encourage you to plan your celebrations on Friday, August 22nd. 

We invite you to join us in celebrating America’s original renewable energy source by posting to social media and amplifying the posts of our industry on this day.

Keep scrolling for tools and tips on how to make your voice heard, including a communications toolkit and a messaging guide.

This Year’s Theme is: Hydro is Here!

As an industry we know that hydropower is a vital resource in the U.S., yet the public isn’t as aware of the value hydropower provides as a cornerstone of clean energy grids and more.

That’s why NHA has selected this theme – to show hydropower’s many benefits to our communities.

  • Local Clean Energy
  • Recreation
  • Local Jobs
  • 24/7 Reliability
  • Irrigation and Flood Control
  • Innovative Solutions
  • …and more!

Schedule a Lawmaker Tour!

NHA also encourages you to invite local lawmakers to tour your business, facility or recreation area in conjunction with National Hydropower Day. You can easily send that request to your Members of Congress by utilizing NHA’s new VoterVoice tool.
