Investment cost of Gravity Storage
Plant construction cost depends primarily on the size of the piston and the geological conditions at the specific location. It is estimated that total investment costs (including planning, grid connection, etc.) for a plant of 8 GWh storage capacity (with diameter approximately 250 m) will typically amount to 200 USD/kWh per storage capacity. The investment can be expected to give a return for at least 60 years, and maintenance costs should be below 1% of capex.
