Technical evaluation of the small hydroelectric power plant “argiri” with capacity of 6,35 mw in argithea municipality, central greece

The project involved the technical evaluation of the design and operation of the small hydropower plant “Argyri”. The evaluation included a review of the hydrology of the basin, the review of the geological and geotechnical parameters of the project, the review of the hydraulic design of the intake facilities and the evaluation of the installed electro-mechanical equipment, including gates, control boards, the turbine and generator complex and the associated facilities. It was found that the plant was generally well designed and built, apart from several intake design inefficiencies which caused unnecessary delays and stop-downs, especially during times of crucial peak load operations. The study resulted in a number of proposals to improve the plant operation, mainly through structural improvements of the intake works.
