Pumped storage hydropower projects are a natural fit in an energy market with high penetration of renewable energy as they help to maximise the use of the renewables that are subject to the vagaries of the weather. Pumped storage provides a load when the there is a surplus of supply and storage that can be recovered later.
Pumped storage hydropower (PSH) can meet electricity system needs for energy, capacity, and flexibility, and it can play a key role in integrating high shares of variable renewable generation such as wind and solar.
As can be seen from the table, while the initial costs of pumped water storage may have been $100/kW, those estimates are all from the 1970's. Once adjusted for inflation, the capital cost ranges from $353/kW to $2,216/kW (2000 dollars) with median cost of about $615/kW, a 20% premium on the cost of a natural gas turbine.
Pumped hydro considered by the Battery of the Nation initiative considers storage sizes ranging from 7 to 48 hours. ISP modelling considered storage as having only 2 hours storage in the case of battery energy storage systems and 6 hours in the case of pumped hydro.
