This diploma thesis deals with a Micro Hydroelectric Power Plant (MHPP) Project. Projects of this type have attracted the scientific interest and have become an integral part of sustainable development. The Hydroelectric Projects are included in Renewable Energy Sources (RES), as they make use of the kinetic energy of water in order to produce electricity. These projects are covered in legislation by the broader context of the RES with specific guidelines for siting , licensing and planning principles. In the framework of the present diplomatic work, the technical and economical study of a Micro Hydroelectric Power Plant Project in GOEV Acheloos, is carried out, which makes use of the flow provided by the passing river of Acheloos, in order to generate electricity and to channel it to the PPC (Public Power Corporation) network. The parts that make up the project are civil engineering works, namely the dam, the intake, the penstock, the powerhouse and the outlet channel and the electromechanical equipment, i.e. the water turbine, the generator and a three-phase power transformer. The dimensioning of each of these projects is a prerequisite for assessing the environmental impact and controlling the financial feasibility of the project. The study area is described both in terms of its geological and climatic elements and its floristic and faunal diversity. Based on the morphology of the region around Agrinio, the siting of the project is designed, i.e. the total area required from the start of the proceedings (dam, water abstraction) until their completion (power plant). The hydrological analysis of Acheloos is based on average monthly flow measurements, which are necessary for the correct dimensioning of the technical works and the energy analysis of the MHPP. During the manufacturing part, dimensioning of the civil engineering works and the electromechanical equipment was conducted and the connection of MHPP to the PPC network was studied. The presence of available substations near the plant was tested, which would, if need be, absorb the power from new RES projects. The main focus of this study is to minimize the environmental impact the present project may cause on the environment. The impact of the project was evaluated with regards to environmental parameters during the stages of construction and operation. For each case of impact identified, the corresponding countermeasure was proposed. Finally, the initial cost of the investment, the operating and maintenance costs, the gross and net revenues from selling the generated electricity and the depreciation period were estimated. The individual cost calculations were based on correlations that emerged from similar case of the company “YDROCHOOS A.E.”. Based on the results, useful conclusions were drawn regarding the viability of the project, as well as the environmental benefits that occur by its construction.
