Pumped hydro energy storage could be used as daily and seasonal storage to handle power system fluctuations of both renewable and non-renewable energy (Prasad et al., 2013). This is because PHES is fully dispatchable and flexible to seasonal variations, as reported in New Zealand ( Kear and Chapman, 2013 ), for example.
