The available analytical tools for planning not only inadequately model Pumped Storage (PS) units, but also underestimate their load-levelling benefits. Therefore, if a PS plant is among the candidate plants, its selection in the final "optimal plan" is highly unlikely. This research deals to assess the complete load-levelling benefits of PS units. The technique used is the Frequency and Duration approach coupled with the Equivalent Load Duration Curve (ELDC) method, used for generation planning. The proposed method is applied to IEEE RTS data and it is shown that almost 50% of PS benefits are not quantified in ELDC method.
