6 FAQs about [Minimum drop of pumped storage]

How do pumped storage systems work?

1. C. Controls and Control Logic. Most pumped storage projects include a water level monitoring and control system for their upper and lower reservoirs’ operation. Many of these systems include automatic features designed to initiate pump/turbine shutdown if the water level rises above preset maximum values.

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.

What is pumped storage hydropower (PSH)?

Pumped storage hydropower (PSH) is a type of hydroelectric energy storage. It is a configuration of two water reservoirs at different elevations that can generate power as water moves down from one to the other (discharge), passing through a turbine. The system also requires power as it pumps water back into the upper reservoir (recharge).

When should a pumped storage facility be reviewed?

Accordingly, when the operational basis of a pumped storage facility has changed or a change is being contemplated, the original design basis of the facility should be reviewed and the following items considered in order to assure the owner the safety of the facility has not been compromised to an unsafe level.

Do pumped storage projects need to be monitored 24 hours a day?

On January 13, 2006 the Federal Energy Regulatory Commission (FERC) issued a letter to all licensed pumped storage projects requiring them to be staffed and monitored twenty-four hours per day, seven days per week.

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.
