What is a pumped storage hydropower facility?

A pumped storage hydropower facility uses water and gravity to create and store renewable energy.

What is adjustable-speed pumped storage hydropower (PSH)?

Executive Summary While the concept of pumped storage hydropower (PSH) is not new, adjustable-speed pumped storage hydropower (AS-PSH) is equipped with power electronics; thus, it has more capabilities and is more agile and flexible to integrate with modern power systems.

What is pumped storage hydropower (PSH)?

Pumped storage hydropower (PSH) is an energy storage solution that uses water and gravity to create and store renewable energy. A PSH facility is located at Bear Swamp on the Deerfield River, which runs from Vermont into Massachusetts.

Is PSH a reliable energy storage system?

PSH facilities use water and gravity to create and store renewable energy. And PSH is nothing if not reliable. As the country adds more renewable energy to the power grid, moving closer to the Biden administration’s goals of a carbon-free power sector by 2035 and net-zero-emissions economy by 2050, that grid will need reliable energy storage.

When was pumped storage hydropower first used in the US?

PSH was first used in the United States in 1930. The first known use cases of PSH were found in Italy and Switzerland in the 1890s, and PSH acts similarly to a giant battery, because it can store power and then release it when needed.

What is a 435 MW hydroelectric power plant?

The facility can be operated purely as a 435-MW hydroelectric power plant, generating power to supply demand for electricity, or as a pumped storage facility, providing energy management and load leveling services while taking advantage of differences in the wholesale price of electricity over the course of the day or the week.
