Introduction
Low-head pumped hydro storage (PHS) is a storage technology that has had a very limited development to date compared to conventional high-head pumped hydro technologies, mostly because of high upfront costs, a high levelized cost of storage (LCOS), and limited flexibility to. Two different studies have highlighted the potential and challenges of low-head pumped hydro storage (PHS), which has so far never been implemented in real projects. It is a configuration of two water reservoirs at different elevations that can generate power as water moves down from one to the other (discharge), passing through a turbine.
