“…This project, which will be the first pumped-storage system in Türkiye, is to be carried out by the Joint Venture formed by two Japanese companies and one Turkish company. Aside from this tangible action for realization of a first pumped-storage hydropower system, there have been quite a few academic theses, technical reports, and papers about pumped-storage hydropower in Türkiye [6,7,8,9,10,11,12,13,14,15,16].…”

“…Yet, the costs of either a reversible turbine-pump system or of a separate turbine-generator and motor-pump system are greater than that of a conventional turbine-generator unit. Therefore, it is obvious that in order for a pumped-storage hydropower project to be feasible, the market unit price of the hydroelectric energy generated during the peak-demand period should be considerably higher than that of the low-demand time, the so-called energy arbitrage as pointed out by both Zhang et al [2] and Firis et al [13]. The price differences in parallel with the grid demands may also affect the overall financial benefit of even the conventional HPPs.…”

New operation simulation models for hydroelectric energy and its financial benefit over an N-year period in daily time steps by the steady-rate and the open-loop night-shift-pumped-storage rules are developed. These models are applied on 11 existing dams in Türkiye, which reflect a wide range of hydrologic and hydraulic peculiarities, for regulations between 90% through 40% and the outputs are compared. Regulation is the ratio of (outflow for energy generation, hm3/day) / (average inflow, hm3/day). The present worths of energy benefits and of pumping costs computed with a discount rate of 9.5% over a 35-year period yield that the night-shift pumped-storage operations are more profitable than the steady-rate rule. Finally, generalized regression equations for average annual produced energy and for present worth of net benefits by both operation rules against statistically significant explanatory variables are developed using the results of these 11 dams, which are all meaningful by relevant statistical criteria.
