The Low Impact Hydropower Institute (LIHI) is a non-profit 501(c)(3) organization dedicated to reducing the impacts of hydropower generation through the certification of hydropower projects that have avoided or reduced their environmental impacts pursuant to the Low Impact Hydropower Institute’s criteria.

LIHI’s Certification Program encourages a range of benefits associated with healthy rivers and enables low impact projects to access renewable energy markets.


The Institute is pleased to announce that the 2nd Edition LIHI Certification Handbook is now released and is available for use.  This new Handbook is based on revised Certification Criteria that were approved at the LIHI 2014 Annual Governing Board Meeting.  All new applications for intake reviews, certification, and recertification that are received in 2016 and later will be subject to the procedures described in the new Handbook.  To access the new Handbook, click on the Handbook button on the right side of the website.  To learn more about the new application process, click How to Apply or use the How To Apply button on the right side or the links above.  Click HERE to view a video recording of a training webinar on the new Certification Handbook.
