This work aims at the economic evaluation of a semi-underground pumped hydro storage power plant erected in an abandoned open pit mine. For the exploratory model-based analysis, we develop and apply both a simple deterministic and a stochastic net present value (NPV) approach, the latter of...

Hydropower optimization includes market prices, the plant-specific technological constraints and the environmental operation constraints set by the regulator. An efficient environmental flow regulation should consider both the improved ecological state of the river system (benefit) and the loss...

Over the past decade Switzerland has invested significantly in pumped storage plants (PSP). They aim to exploit arbitrage opportunities by pumping water from a lower reservoir to an upper reservoir to store electricity in the form of hydraulic potential energy when prices are low and generating...
