The main goal of this paper was to obtain all acceptable locations for siting of wind turbines in the region of Central South Serbia. One of the possibilities to increase the rentability of the wind farm is to reduce the transport loses, using produced energy as close to the production site as possible. The estimations were obtained using the WAsP ...
