IPSP — Intermountain Pumped Storage Project
By Premium Energy Holdings, LLC. Engineering by Power-Tech Engineers, Inc. & WAPCOS Ltd. — Delta City, Millard County, Utah.
Preliminary permit issued December 18, 2019
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 the permit was issued (December 1, 2019). The purpose of a preliminary permit is to preserve the right of the permit holder to have first priority in applying for a license for the project under the Federal Power Act, allowing Premium Energy Holdings to conduct investigations and secure the necessary data to determine the feasibility of the project and to prepare a license application.
2,000 MW near Delta City, Utah
The Intermountain Project will be located northeast of Delta City within Millard County, Utah. The proposed 2,000 MW pumped storage project 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 three alternatives located east of the project in the Canyon Mountains Range.

Pumped storage, explained
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 relevant to the U.S. power grid?
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 pumped storage generators were built in the 1970s. The ever-increasing energy demand challenges electric utilities and investors to keep pace by developing long-term projects that help cover the electric demand. Besides providing energy supply, pumped storage also provides reliability to the grid.
What is the difference between open-loop and closed-loop pumped storage?
Closed-loop pumped storage projects have a lower and upper reservoir which are not connected to any other body of water (such as a river); the same water is repeatedly used in the charging and discharging process. Open-loop projects are connected to an ongoing stream of water, which is used in the charge/discharge process to store and deliver energy — 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 of collecting electrical energy when there is an excess of generation, and delivering it to the grid later. The most common large-scale energy storage is pumped storage, which can replace thermal generation, substitute the need for spinning reserve, or increase reliability and stability of the grid. It is also used to store energy from intermittent renewable sources such as solar or wind farms.
How can pumped storage help with renewable-energy integration?
Pumped storage facilities can help meet greenhouse gas emissions reduction targets and build clean renewable energy capacity. In addition, these plants 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: 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 with a typical lifespan well over 50 years, and it is the most cost-effective solution for large-scale energy storage — compared to batteries, which currently last between 8 and 15 years.
