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 committed to environmental, cultural and recreational stewardship 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.

Proposal to Expand Eligibility for New Construction

At the December 2018 meeting, LIHI’s governing board approved a proposal to consider changing the eligibility for newer dams and diversions.  The proposal is based on the understanding that unless we reconsider the vintage date criteria for eligibility, LIHI Certified® hydro will become a rapidly decreasing resource in both the voluntary market and in some state compliance (RPS) markets. Further information and all comments that were submitted can be viewed HERE.


We are proud to announce that LIHI has been recognized as 2018 Non-Profit of the Year by The Cleanie Awards
