Background

On December 18, 2019, the FERC issued the preliminary permit to Premium Energy Holdings, LLC (PEH), for a period effective the first day of the month in which this permit is issued (December 1, 2019). The purpose of a preliminary permit is to preserve the right of the permit holder to have the first priority in applying to a license for the Project under the Federal Power Act, allowing Premium Energy Holdings to conduct investigations and secure necessary data to determine the feasibility of the Project and to prepare a license application.

About the Project

The Intermountain Project will be located northeast of Delta City within Millard County, Utah. The project is a proposed 2000-megawatt (MW) pumped storage project that would use a proposed DMAD 2 Reservoir as the lower reservoir, one mile upstream of the existing DMAD Reservoir. The proposed upper reservoir, could be any of the three proposed, located east of the project in the Canyon Mountains Range.

Documents

PEH Licensing Documents

Premium Energy Holdings, LLC will be developing and publishing a variety of documents throughout the licensing process. The following documents are associated with the Integrated Licensing Process (ILP):

FERC Licensing Documents

The Federal Energy Regulatory Commission (FERC) will issue documents related to the Intermountain Pumped Storage Project licensing. The documents will be available when issued.

FAQ

What is Pumped-Storage Hydropower?
Please, check out this video provided by the U.S. Department of Energy,  What is Pumped-Storage Hydropower.
 

Why is Pumped-Storage (PS) Hydropower relevant to the U.S. power grid operation? 
Currently, Pumped-Storage accounts for around 95% of all utility-scale energy storage in the U.S. However, as stated by the Energy Information Administration (EIA), most of the PS Generator were built in the 1970s. Also, the ever-increasing energy demand challenges electric utilities and investors to keep pace by developing long-term projects that may help to cover the electric demand. Pumping-Storage, besides provinding energy supply, it also provides reliability to the grid.
 
What is the difference between Open-Loop and Closed-Loop Pumped-Storage Hydropower?
Closed-loop pumped storage projects have a lower and upper reservoir, which are not connected to any other body water (such as a river). The same water is repeatedly used in the charging and discharging process.
Open-loop pumped storage projects are connected to a ongoing stream of water, which is used in the charge/discharge process to store and deliver energy. The storage capacity depends on the water available in the natural water feature.
 
What is the benefit of a Closed-Loop system over an Open-Loop system?
In general, Closed-loop projects have less impact on aquatic resources. These impacts are primarily related to the initial reservoir filling process.
 
Why do we need Energy Storage? 
Energy Storage consists on collecting electrical energy when there is an excess of generation, and deliver it to the grid later.
The most common large-scale energy storage is pumped storage, which can be used to replace thermal generation, substitute the need of spinning reserve, or increase reliability and stability of the grid.
It is also used to store energy from intermitent renewable energy sources, such as solar or wind farms.
 
How can Pumped-Storage help with renewable-energy integration?
Pumped-storage facilities can help meeting greenhouse gas emissions reduction targets and build clean renewable energy capacity. In addition, these plants can enhance the reliability and stability of the grid.
 

Is Pumped-Storage safe?
Any storage solution must comply with safety requirements in order to be sustainable. The main risk related to pumped storage facilities is dam safety. If it occurs, dam failure can affect downstream communities and the environment. Nevertheless, pumped hydro technology is mature, dam risks are generally well understood and managed, and the frequency of dam safety events is very low.
 

What is the lifespan of a Pumped-Storage project?

Pumped-Storage Hydro is a proven technology and has a typical lifespan well over 50 years, and is the most cost-effective solution for large-scale energy storage, compared to batteries, which currently last between 8 and 15 years.
