Hydroelectric power is based on the exploitation and the conversion into electricity of the dynamic energy of the kinetic energy of the water of the rivers. This conversion takes place in two stages. In the first stage, via the impeller of the turbine, we have the conversion of the kinetic energy of the water into mechanical energy in the form of rotation of the impeller shaft and to the second stage, through the generator; we achieve the conversion of mechanical energy into electricity. All the individual works and the equipment through which we achieve the conversion of hydraulic into electrical energy comprise a Hydroelectric Project.
The Hydroelectric projects utilize the renewable and inexhaustible natural resource “water” of each proposed area which fulfils the requirements of Greek legislation for the installation of a hydropower project. Hydropower based on taking advantage of the dynamic energy of the water via the rivers and the natural or artificial barriers.
The development of a hydroelectric plant is a complex and long-term project which is consisted of different phases and auxiliary projects whose construction is based absolutely on accurate and in-depth studies conducted by specialized civil engineers, topographers, mechanical engineers, electrical engineers, geologists and energy studies experts. Its implementation consists of road construction works and improvements of the existing roads for ensuring the accessibility of the project’s location, the construction of the barrier for the control of the water into an artificial lake, the construction of a channel of many kilometers and the development of the building for the installation of the turbines with the generators and the establishment of the telesurveillance/telecontrol systems.
The storage of quantities of water in natural or artificial ponds, for a hydroelectric project, is practically equivalent to hydro power savings. Also, the programmed release of such quantities of water and their expansion in turbines leads to the controlled production of electricity. Given the adequate water resources and the adequate supplying of them with the necessary rainfall, hydroelectric power is becoming one of the leading alternative renewable energy sources.
