HPP Makrochori II is planned to be constructed on the downstream edge of river Aliakmonas outlet of the existing irrigation canal A0 and is planned to produce electricity when there is no irrigation demand (e.g. in winter months). The existing outlet lies near the village Rapsomaniki. For this project, necessary licenses for production were already obtained. The project was executed in two phases. The first phase included the preparation of preliminary studies for civil and electromechanological works and the second phase (after the Client's approval) contained the preparation of the detailed design study of the total project. The project was tendered.




CONSULTANCY SERVICES FOR DAMS SAFETY INSPECTION IN HYDROPOWER STATIONS IN KENYA

RFP

The services provided by the Consultant focused on the assessment of dam safety for the following hydroprojects, owned by the Kenya Generating Company in: (a) Upper Tana basin, (b) Lower Tana basin and (c) some isolated stations. The safety assessments concerned dam safety, that is the safety of the water retaining structures themselves, as well as any appurtenant structures related to the safety of the dams themselves, such as spillways, bottom outlets, etc. Dams and their appurtenant structures were inspected by highly experienced engineers, based on detailed checklists for (a) the crest area, (b) the downstream slope, (c) the upstream slope, (d) the installed instrumentation, (e) the downstream area, (f) the spillway and (g) the galleries [for seepage, inspection, access, etc] and bottom outlet chambers of each dam. Training workshops were organized in Nairobi including presentation and training on key issues related to dam safety and, finally, presentation of the particular characteristics, safety issues and monitoring demands of the Ken Gen dams.




TECHNICAL EVALUATION OF THE SMALL HYDROELECTRIC POWER PLANT “ARGIRI” WITH CAPACITY OF 6,35 MW IN ARGITHEA MUNICIPALITY, CENTRAL GREECE

RFP

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.
