Low Impact Hydropower Institute

The Low Impact Hydropower Institute (LIHI) is a 501(c)(3) non-profit organization whose primary purpose is to: 1) set criteria for characterizing hydropower facilities that are low impact; 2) conduct a program to certify that hydropower facilities meet these criteria; and 3) make information about the impacts of hydropower available to the public.

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