Recent advances in utilisation of renewable energy for power generation have boosted the development of renewable-energy market. Power generation using renewable energy gradually reduced carbon dioxide emission. Wind energy is one of the fast growing energy resources around the world. However, some assessments on the suitability of wind energy to be harnessed in Malaysia are needed before wind turbines can be established. In this research, a feasibility study of the utilisation of wind energy in Kudat has been conducted. Feasibility studies include the potential wind power site selection, wind speed prediction, wind turbine selection, economic and system assessment. A hybrid multi criteria decision making method with original values of the parameters has been introduced to identifl the suitable location for wind power plant. In recent years, Malaysia is moving towards sustainable energy growth by giving tax exemption and financial supports to green energy developers. The economic assessment on the Malaysian government's policies has been carried out by using system dynamics analysis. System dynamics can perform holistic analysis from the planning until establishment of the project and generate the desirable scenario by changing the values of parameters. Wind speed prediction is one of the criteria for future power planning. Wind speed prediction in Kudat in 2010 has been investigated among three methods, which are Mycs-3, K-means clustering and Weibull analysis. Through the prediction of K-means clustering, the root mean square error is reduced 0.5% and more accurate if compared with Mycs-3. Besides, the financial planning of the wind power project based on Green Technology Financial Scheme (GTFS) 2010 was successfully developed. By using Vestas 3MW wind turbine as the study object, the return of investment is expected in between five to thirteen years. This is promising since the conventional power plant has typical ROI of ten years. In a nutshell, wind power plant is workable for the scenario in Malaysia.
