What conditions must pumped storage meet

Why is pumped storage important?

Pumped storage provides the opportunity to meet variable load demands; modern pumped storage provides peak and variable load regulation in both pumping and generating modes. The current decarbonization plan for the electric grid in the United States is predicted to greatly increase the need for additional pumped-storage projects.

Does the United States need new pumped storage?

The United States needs new pumped storage to meet its long-duration energy storage needs and support its federal and state renewable energy targets. This report provides an analysis of PSH’s evolution and technological advancements and suggests strategic actions to overcome existing barriers specific to the United States.

Is it a good time to build a pumped-storage facility?

The current decarbonization plan for the electric grid in the United States is predicted to greatly increase the need for additional pumped-storage projects. With the Biden Administration making a clear push to bring more renewable energy on-line, this could be a favorable time to develop a pumped-storage facility.

What is a pumped storage facility?

Pumped storage facilities are built to push water from a lower reservoir uphill to an elevated reservoir during times of surplus electricity. In pumping mode, electric energy is converted to potential energy and stored in the form of water at an upper elevation, which is why it is sometimes called a “water battery”.

What should be included in a pumped storage project?

2. C. Each Pumped Storage project should have a design change/ configuration control program. This program should ensure the design basis of the plant is controlled and maintained through procedures and processes that assure unauthorized changes are not made to equipment important to safety.

When should a pumped storage project be staffed?

The January 13, 2006 FERC letter or more current FERC guidance should be considered by the licensee when determining the staffing of a pumped storage project. Un-staffed operation should only be considered when robust fail safe systems, procedures and processes are in place to support unattended operation.
