How many terawatt-hours can a closed-loop pumped storage hydropower system produce?

A GIS-based analysis of potential new closed-loop pumped storage hydropower (PSH) systems in the contiguous United States, Alaska, Hawaii, and Puerto Rico finds technical potential for 35 terawatt-hours (TWh) of energy storage across 14,846 sites, which represents 3.5 terawatts (TW) of capacity when assuming a 10-hour storage duration.

How many GW of pumped Energy Storage will there be by 2050?

In fact, as demonstrated in DOE’s Hydrovision Report, there is potential for 50GWs of new pumped storage in the United States by 2050. Globally, PSH provides 160 GW of the approximately 167 GWs of energy storage in operation.

What is pumped storage hydropower?

Pumped storage hydropower is the most dominant form of energy storage on the electric grid today. It also plays an important role in bringing more renewable resources onto the grid. Currently, about 93% of all grid-scale energy storage capacity in the U.S. is provided by pumped storage hydropower (PSH).

What is pumped storage hydropower (PSH)?

U.S. DOE (2018) “Global Energy Storage Database Projects.” Pumped storage hydropower (PSH) long has played an important role in America’s reliable electricity landscape. The first PSH plant in the U.S. was constructed nearly 100 years ago. Like many traditional hydropower projects, PSH provides the flexible storage inherent in reservoirs.

What is a closed-loop pumped storage hydropower resource assessment?

This recently completed Closed-Loop Pumped Storage Hydropower Resource Assessment for the United States is a large-scale study of potential closed-loop PSH sites and an important reference for developers and stakeholders.

Are pumped hydro facilities a viable option for energy storage?

For example, the Department of Energy and the Electric Power Research Institute's handbook on energy storage concluded that “the addition of pumped hydro facilities isvery limited, due to the scarcity of further cost-effective and environmentally acceptable sites in the U.S.” .
