A monitoring and feasibility study of wind power utilization at Munro College, Jamaica, has been performed using observed wind speeds and direction and the operational characteristics of a 225 kW wind turbine generator (Vestas 27-225), installed at the College. The analysis of the data collected over a period of approximately one year indicates that the estimated net annual energy from the turbine is 4.68 x 105 kWh and the average capacity factor is 35%. Based on the estimated net annual energy and the average capacity factor, wind power at Munro is technically feasible. However, it appears that the turbine average power output is approximately 7% lower than expected. This may be due to the terrain and roughness elements, and the turbulence intensity of wind at Munro. The fluctuation in power output is also a major draw back. The estimated costs of energy production show promise in competition with the present local costs of production at private power plants. The economic advantage of using wind turbines at Munroe will depend largely on the initial investment scenario and the economics may become more favourable if larger turbines are used to capture wind energy at lower speeds. An inspection of the environmental feasibility of the wind turbine at Munro indicates that adverse environmental impacts would not appear to be issues of concern.....
