Small Hydro Power Plants in a given region in Norway;
Small hydropower plants in Sør-Trøndelag

Nielsen, Torbjorn
Nowadays, the hydropower development in Norway is more or less restricted to small scale installations without reservoirs as they are regarded as an environmentally solution. This thesis provides an overview of the hydropower potential of nine rivers in Sør-Trøndelag, a county in Norway. This feasibility study includes technical, economical and environmental considerations. There is a combination of theoretical, experimental and programming work. First of all, the hydropower plants locations were positioned on a map. The rivers considered are not gauged so the runoff data was scaled from a metering station in an adjacent watershed. Once the head and the runoff were determined, the hydropower was calculated. The main objective of this thesis is to build a user friendly program that estimates the costs of small hydropower plants, that consists of the cost of its components. The main components of a small hydropower plant are technically described: intake dam, intake gate or valve, trash rack, pipes, powerhouse, turbine, generator, crane, transformer, controller, switchgear and power cable. The program was developed with Microsoft Office Excel 2003. There are three different versions of the program: one that provides a general overview of the costs, another one that provides the costs for each component separately and finally one that optimizes the hydropower plant design. The profitability of the small hydropower plants projects was discussed in the economic analysis. Environmental aspects were, as they always should, considered when planning the hydropower plants. To take this investigation a step further one river was selected to undergo verification of the data. A field survey was made to check the location of the hydropower plant in its natural surroundings and to measure the flow of the river. The dimensions of the pipe and of the Pelton turbine were calculated. This thesis can be used as a guide for the landowners eager to developing hydropower on their property.
