Neom's utility subsidiary, Enowa, is expected to issue the request for proposals (RFP) for a contract to develop and operate the first phase of Neom's pumped hydropower storage (PHS) network in the fourth quarter of 2024. [pdf]
State-owned power utility Elektroprivreda Srbije (EPS) has announced a tender to develop a preliminary design and feasibility study for the construction of a pumped-storage hydropower plant (RHE) Bistrica. [pdf]
Pumped storage plants can operate with seawater, although there are additional challenges compared to using fresh water, such as saltwater corrosion and barnacle growth. Inaugurated in 1966, the 240 MW in France can partially work as a pumped-storage station. When high tides occur at off-peak hours, the turbines can be used to pump more seawater into the reservoir than the high tide would have naturally brought in. It is the only large. [pdf]
