Dry Canyon Pumped Storage

The proposed 1,800 megawatt Dry Canyon pumped storage project is a closed-loop pumped storage hydroelectric generating facility in southeastern Idaho, approximately 14 miles south of Montpelier, Idaho. 

PacifiCorp submitted the Preliminary Permit Application to the Federal Energy Regulatory Commission (FERC) on October 13, 2021 to preserve our licensing position while we conduct initial technical feasibility studies regarding the Dry Canyon project. After completing initial technical feasibility studies, the company may conduct additional studies to further assess the effects of the potential project on the environment. FERC has designated this Project No. P-15240.

It is anticipated that FERC will issue a Preliminary Permit early in 2022. Once the Preliminary Permit is issued, feasibility studies may begin.
