A Bright Energy Future for Southeastern Kentucky


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 $1.5 billion+ project will create 1,500 jobs and deliver enough clean energy to power about 67,000 homes annually.

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 renewable energy from wind and solar power is plentiful, this excess energy 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 renewable electricity.

The system is filled with water once, and then re-uses that water, over and over. It repeats the cycle, continually storing and dispatching renewable energy.
