Pumped hydro storage (PHS) is the most common storage technology due to its high maturity, reliability, and effective contribution to the integration of renewables into power systems. Accordingly, it is essential to achieve the optimal operation of energy systems combined with PHS.
Existing conventional hydropower plants can be retrofitted with pumping systems to integrate PHS capabilities. Currently, PHS can be considered a very versatile energy storage solution owing to its functionality over a wide range of timescales.
Pumped hydro energy storage is undoubtedly the most mature large-scale energy storage technology. In Europe, at the time being, this technology represents 99% of the on-grid electricity storage (fig. 2).
