Malaysia offshore regions have the potential for the development of the Horizontal Axis Wind Turbine (HAWT) wind turbine, where the annual mean wind speed is greater than 4 m/s. Although the annual wind speed meets the minimum requirement for wind turbines to generate electricity, the steady wind flow is still lower compared to other countries. Therefore, the purpose of this paper is to optimize the parameters of the wind turbine blades to improve the performance and power production of HAWT for the usage in Malaysian sea. The performance and power production of optimized turbines in array arrangement is also investigated. Computational analysis using software Qblade was performed to evaluate the result of power production of blade properties including blade diameter and blade angle of attack, while Computation Fluid Dynamic (CFD) is used to evaluate the performance in array arrangement when subjected to Malaysia sea conditions. Results show that a wind turbine blade with a diameter of 150m and blade angle of attack of 6 degrees has the better performance in the variation of wind speed. In staggered wind farm configuration, the estimated total power output of 20450.83 kW is expected to be obtained by 6 units of turbines.
