The motivation to use pumped hydro in India comes primarily from the desire to meet peak electrical demand; the peak power capacity is short of the peak demand in most states by 10–15%. The aim for pumped hydro plants is therefore to shift electricity from off-peak to peak hours. However most PHES plants have been unable to perform to their full potential due to
