From the beginning of 20th century, huge tensions rising about global warming and environmental pollution from utilizing fossil fuels enormously. Implementing pump hydro storage profoundly can reduce the extensive use of fossil fuels and ameliorate the green energy production. Regarding this, Kuli PHSP (Kuli pumped hydro storage project) has been studied in this thesis. This study focuses on planning and designing of possible tunnel layout alternatives for Kuli PHSP. Tunnel layouts are selected with minimum geological conﬂicts and maximum utilization of natural resources. 1D numerical simulation of waterway systems have carried out to determine the system stability during pump-turbine operation. Threshold price is imposed based on roundtrip eﬃciency losses to regulate the plant operation. From this regulation strategy net production energy is calculated and a ﬁnancial analysis is conducted by employing total project cost for each alternative. Finally, an economic and sensitivity analysis is performed to estimate the projects economic feasibility and robustness. Regarding this outcomes best alternative is selected for further investigation.
