However, as the renewable fraction approaches 100% then substantial storage is needed. Analysis of Australia showed that about 500 GWh of storage is needed to balance a 100% renewable electricity grid for 25 milli...See more on re100.eng.anu Engineers Australia[PDF]
Pumped hydro energy storage - Engineers Australia
Large-scale storage is required to support high levels of solar and wind energy. Many methods of storage are available, and most will find a niche. This paper focuses on pumped hydro energy
