Offshore area based power production from wind turbines demands a reduction of the size of generators, from the MW scale to the kW scale for economic and power production feasibility. Based on that, small-scale vertical axis savonius wind turbines (VASWT) will be a good choice for an on-site generation (OSG) as it has no issues for turbulent flow and low velocity of the wind. It also has a minor acoustic impact than that of HASWTs. Among various types of turbines, a prototype of a single-stage type savonius rotor VAWT is constructed in the lab with a capacity of 500 W according to a previous simulation outcome. The performance of this turbine is evaluated in this paper by equipping it with an electric generator by connecting to the rotor shaft through a toothed wheel gear. The output of the turbine was calculated by implementing artificial wind from a heavy fan. The potentiality of the designed wind turbine is also presented for the various coastal region of Bangladesh.
