# Feasibility study of a hydropower project: case study of Niksar HEPP, Turkey. | Feasibility study of multiple hydropower project: case study of Baltacı stream, Trabzon, Turkey |. Hydropower is among the most widely used type of renewable energy. Development of a small hydropower project is a challenging engineering task. | Feasibility of a supplementary water storage for birkapili hydroelectric power plant |. Hydroelectricity is the most widely used form of renewable energy and refers to electricity generated by hydropower. In this study, a storage facility is proposed to store some additional water and increase the profitability of the existing Birkapılı Hydroelectric Power Plant. Rule curve which results in the maximum energy generation has to be developed for each hydropower plant (HEPP). | The objective of this thesis is to develop a decision support tool to assess the feasibility of a hydro electrical power plant (HEPP) investment option by estimating its profitability under various scenarios.

# Hydropower Feasibility Study. Whether you are assessing a small private hydro scheme, a community hydropower project or a larger commercial installation, a feasibility study provides the technical and financial foundation for successful project development. Hydropower systems have to be ‘bespoke designed’ to fit into a site, rather than onto a site as is the case with wind turbines, so the site survey is a particularly important part of a hydropower feasibility study. A key element of the hydro site survey is to get a good understanding of the layout of the weir(s), channels, sluices and surrounding buildings so that some initial options for locating the hydro system can be discussed with the client. Accurate flow estimates are a vital part of our hydropower feasibility study because they form the basis of the performance and income predictions for the hydro system and are a key element when specifying the most appropriate hydro turbine.
