What is subject pumped storage hydropower (PSH)?

Subject Pumped Storage Hydropower \(PSH\) is currently the largest source of utility-scale electricity storage in the U.S. and worldwide. As the accelerating deployment of variable renewable technologies creates opportunity and value for energy storage, it has be\come increasingly important to characterize PSH costs to understand how it competes.

What is a PSH cost exploration model?

The model was developed in consultation with HDR, Inc. and Small Hydro Consulting to ensure it aligns with industry expectations. It enables PSH cost exploration\ across a wide range of system assumptions and could be customized or extended for the needs of a variety of users.

How is mean generation discharge calculated?

Mean generation discharge is calculated in cubic feet per second using the ratio of active storage and the specified generation duration along with unit conversion factors (43,560 acre-foot/cubic- foot and 3,600 seconds/hour).

How many embankments does a reservoir need?

The upper reservoir requires two embankments. The south embankment (URD -1) will have a height of 120 feet and a crest length of 1,300 feet. 9 The upper reservoir requires two embankments. The west embankment (URD-2) will have a height of 60 ft and a crest length of 1,100 feet. 10
