Small Hydro Power Plants Doboj, Cijevna 5 and Cijevna 6 in Republic of Srpska – Feasibility study

Client: Technor Energy AS, Norway

Name of partner(s): Institute for civil works IG, Banja Luka

Start/Completion Date: March 2008 – September 2008

Project description: Small hydro power plants Doboj, Cijevna 5 and Cijevna 6 are planned within integral project of development, protection and exploitation of the Bosna River course in the stretch between Doboj – Modrica, including also parts of the river stream through Doboj and Modrica cities. Feasibility Study is to investigate above mentioned facilities techno – economical validity and its impact both on power system of Republic of Srpska and on local environment and nature. Main structures for each SHPP are spillway for 3000-3600 m3/s, gravity part (dam) height cca. 20 m, powerhouse as constituted part of dam. SHPPs are river –type, with installed capacity 8,4-2x13 MW and average annual production 37+2x63 GWh/year. The services that were rendered by the Consultant refer to the following activities:

• Using the available input data related to the basic factor of the area related to morphological characteristics, existing and planned infrastructure and inhabitancy of the watercourse and watershed, as well as extent to which they have been investigated.
• Conducting the comprehensive procedure of collecting all necessary input data like geodetic, hydrological, geological and hydro geological, seismological data as well as input data related to erosion and sediment transport;
• To find optimal technical solution for these facilities construction. This included the selection of conceptual solution for usage of technically exploitable hydropower potential, selection of key structures within hydropower plants, hydro-civil solutions. Also the potentials of the analyzed facilities investigations regarding calculation of power characteristics of plant, electromechanical equipment, hydro mechanical equipment, potable water supply to structures, wastewater, environmental impact assessment for hydropower plants is be conducted;
• Estimation of both total and individual costs.
