The Northwest Hydroelectric Association was incorporated in 1981 by a group of folks who were interested in building new hydropower projects, some Northwest legislators and a group of consultants. At that time, it was known as the “Northwest Small Hydroelectric Association.” Later utilities and other developers joined, increasing the capacity of projects and then the name of the organization was amended to its current form. NWHA is a 501(c)(6) non-profit organization.
