Pumped hydro energy storage system: A technological review
Recently, Kotiuga et al. [138] conducted a pre-feasibility study of a seawater pumped storage system and showed that a 1000 MW pumped storage plant, that could generate power for 8 h, would eliminate the need for 1000 MW thermal plants burning heavy fuel oil. The study identified a number of potential sites and ranked them using multi …
