A STRONGER ENERGY FUTURE

The Gregory County Pumped Storage Project offers a reliable, responsible solution to the pressing need for alternative sources of power when the wind isn’t blowing and the sun isn’t shining. Learn more about this project and its numerous benefits to communities throughout our region.

THE GCPSP AT A GLANCE

How It Works

  • Renewable energy such as wind or solar is used to pump water uphill during times of low customer usage
  • When electrical usage increases, or wind/solar production drops, water is released and runs downhill from the upper reservoir
  • Water runs through the turbine, generating electricity
  • Combining pumped storage hydro with intermittent renewable resources results in clean, dependable power supply.
