PUMPED STORAGE HYDRO

Large water reservoir with curved concrete walls under a blue sky with few clouds.

As we continue to integrate significant amounts of intermittent energy into the grid, we have to solve the energy storage problem in a big way.

Pumped storage hydro helps keep the power grid stable, can quickly restart parts of the grid during a power outage, and can go from completely off to full power in just 90 seconds.

Diagram showing how pumped storage hydro works, with water flowing from upper to lower basin, powering a turbine and motor-generator, and storing energy for power generation.

Pumped storage keeps the lights on, storing energy when there’s plenty and sending it back when we need it most.

Pumped storage hydro plants store energy and generate power by moving water between two reservoirs at different elevations. Over and over again.

Once built, pumped storage hydro plants have an unmatched operational lifespan of more than 75 years. While pumped storage has been in use for nearly a century, almost no pumped storage hydro plants have yet reached retirement.  As the demand for energy in the U.S. increases, pumped storage can store and deliver renewable energy to the grid for the next century.

With up to ten hours of full-capacity storage, the plants can provide power during peak load periods.

SEMINOE PUMPED STORAGE

Project Highlight

THE MODERN ENERGY HUB FOR WYOMING WIND ENERGY

THE MODERN ENERGY HUB FOR WYOMING WIND ENERGY

The Seminoe Pumped Storage project is a 972 MW energy storage project being developed near Rawlins, Wyoming. The project works like an energy savings account. Storing power when there’s extra and releasing it when demand spikes. It does this by moving water between two reservoirs, one of which is the existing Seminoe Reservoir. It will help make electricity more reliable and is designed to serve the region for generations.
