Pumped Hydro-Energy Storage System

Pumped hydro energy storage (PHES) is a resource-driven facility that stores electric energy in the form of hydraulic potential energy by using an electric pump to move water from a water body at a low elevation through a pipe to a higher water reservoir (Fig. 8). The energy can be discharged by allowing the water to run through a hydro turbine

Drivers and barriers to the deployment of pumped hydro energy storage

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.
