Comment Period Open – Draft Definition of Low Impact Pumped Storage Hydro

February 19, 2025: In collaboration with an external Advisory Group representing a broad cross section of the hydropower community, the Low Impact Hydropower Institute (LIHI) has developed a draft definition of Low Impact Pumped Storage Hydropower (LI-PSH). The definition and supporting documentation could help provide an outline for best practices in developing and operating LI-PSH projects. Once public comment has been received and the definition finalized, the LIHI Governing Board may consider creating a Low Impact certification program for LI-PSH projects.

LIHI would like to hear from interested parties on this draft definition.  The draft definition and details about how to comment can be found 這裡.  Comments are due by 5 pm Eastern time on May 20, 2025.
