This is a feasibility study that examines various aspects of building a wind farm on Malmön in Norrköping. The feasibility study deals with interests of conflict, park design, electrical connections, production calculation, financial calculations and operating- and timetable. The report is divided into two distinct parts. First a theoretical part, which deals with conflicting interests, park design and electrical connections. Second a part with simulations dealing with production calculations, and financial calculations. Opposing interests are mapped so that problem areas can be found, and help put focus on the right places at a future environmental impact assessment (EIA). There are a number of areas where planners have to assess on an EIA, this thesis point on the most important areas. There are a few areas of national interest and the Natura 2000 protection. Part of the area of the planned park is also within Norrköping Airport area of influence and an assessment must be made by the civil aviation authority (CAA) to determine if a wind farm on the location would affect the air traffic and if so, what part of the location would be affected. Furthermore, there is the area of a flight route for birds as well as an area that is a common livelihood for birds. These should be examined to see if wind power in the area can become a problem for these birds. A production calculation has been implemented in the program WindPRO. This feasibility study has dealt with three different park designs with the wind turbine, Vestas V-126 3.3MW, which is the largest low wind turbine we found. Based on wind data, data for wind turbines, distance between turbines and other data we can do a calculation of how much energy the wind farm produces annually. Calculations were also made In WindPRO regarding sound levels and shadow creation. This is so that the wind farm will be designed so target values for noise and shadows are met. All park designs in this project has been designed so that the sound and shadow benchmarks for buildings nearby are met. Based on production estimates, an economic calculation been carried out. The different park designs have between 7 and 11 wind turbines with an annual energy production of between 58 and 91 GWh per year. The wind turbines have been estimated to cost approximately 25 Mkr each, plus about 10 % of turbine cost for foundations, roads, power lines and other similar expenses. One calculation was made for the case the electric connection could be done directly to some of the industries in the location, for this simulation the cost over the wind mill was about 15 %. Under all these conditions, the project should be financially sustainable, with a payback period of about 6-11 years and a return of investment of 1-7 %.
