Storage

Pumped storage hydro is a reliable, utility-scale energy storage technology. In 2021, we submitted to the Federal Energy Regulatory Commission 11 applications for preliminary permits at potential pumped storage sites across our service area. This will allow PacifiCorp to evaluate the ability of pumped storage at these locations to assist in our energy transition while preserving our priority to submit license applications at these sites if they are determined to be feasible and beneficial to our system.

It is anticipated that FERC will issue Preliminary Permits in the near future. Once the Preliminary Permits are issued, feasibility studies may begin.
