dc.description.abstractPower generation from flowing water is known as Hydropower generation. It is one of the major capital-intensive projects that require detailed technical as well as financial analysis before making an investment decision. The cost of Electro-Mechanical (EM) equipment including turbines, generators, controls autonomous and auxiliaries hold the remarkable portion of the hydropower project budget. The cost of the EM equipment is mainly related to the installed capacity and net head of hydropower. This research aims to develop the mathematical relation as well as the cost estimation nomogram to estimate the unit cost (per kW) of EM equipment accounting for the installed capacity of the hydropower plant and available water head. Technical and Financial Details of eighteen hydropower projects with either Pelton or Francis type turbine units were collected and analyzed for the actual unit cost by multivariate linear regression method. Obtained mathematical relationships were then compared against the primary data of actual costs. The developed relations show that the MAPE (Mean Absolute Percentage Error), Standard Deviation (SD), and adjusted R2 for Pelton and Francis-based hydropower yields 5.81%, 6.9%, 75.89% and 8.12%, 10.2%, 80.93% respectively. From the value of MAPE obtained, it can be inferred that the modeled equation provides an excellent accurate estimation. A cost estimation nomogram for the range of 50m to 800m net head for Pelton and 30m to 300m for Francis-based hydropoweren_US
