About the project

Energy storage plays a vital role in the renewable energy transition and a new, modern energy system by providing flexible, reliable and quality power, when we need it most.
 
Pumped hydro is a proven and reliable form of energy storage, allowing energy to be stored for longer than most current battery technologies.

It works by using two reservoirs of water – one up high and one down low to store energy and generate electricity. When solar and wind power is plentiful, this energy is used to pump water from the lower reservoir to the upper reservoir.

When energy is needed, the water from the upper reservoir is released back into the lower reservoir turning turbines which generate electricity. This electricity is sent to the grid for use in homes and business.

We are progressing the development of a pumped hydro energy storage project on land and waterways we own near Lithgow.

The NSW Government has declared the project as Critical State Significant Infrastructure (CSSI), highlighting its importance as essential, high -priority infrastructure for the state.
