Map of U.S. Pumped Storage Hydropower Development Pipeline, 2025

This map provides a snapshot of the composition of the U.S. pumped storage hydropower development pipeline as of December 31, 2024. It displays the location of pumped storage hydropower projects whose developers have formally registered interest in project development through documents submitted to FERC or Bureau of Reclamation. The map provides project-level information on type, size, and development process stage. It also includes a base layer categorizing states by their variable renewable (wind and solar) shares of electricity generation capacity.
