Overview
The Lewis Ridge Pumped Storage Project will strengthen and stabilize the power grid by delivering 24/7 on-demand electricity from a proven, reliable technology. Located in Bell County, Kentucky at a former coal mine, the $1.3 billion+ project will create 2,300 family-wage construction jobs and generate enough on-demand energy to power about 70,000 homes.
The most common and widespread form of energy storage, pumped storage hydro helps safeguard our electrical grid against blackouts, extreme weather events, and other potential crises that can disrupt the economy and our way of life.

How It Works
Pumped storage facilities rely on gravity to produce energy. The system moves water between a lower reservoir and an upper reservoir. When energy is plentiful, excess power is used to pump water from the lower reservoir to the upper reservoir. Then, when demand for power is high, water is released from the upper reservoir and used to turn hydroelectric turbines to generate on-demand electricity. This on-demand energy is critical to ensuring reliability during extreme weather events and to also maintain the stability of the system in daily operations.
The system is filled with water once, and then re-uses that water, over and over. It repeats the cycle, continually storing and dispatching reliable energy.
