In this hourly wind speed data for nine sites in Malaysia are used to optimally design wind power systems. These sites are Bintulu, Kota Kinabalu, Kuala Terengganu, Kuching, Kudat, Mersing, Sandakan, Tawau and Pulau Langkawi. However, the designed wind power systems are supposed to supply hourly load demand (6.13kWh/day, 0.52 kW peak) at 1% loss of load probability. The cost of energy for each system is calculated and compared to the cost of energy of a standalone PV power system, a diesel generator power system and the electricity grid. The results show that the average cost of energy for wind power system in Malaysia is (1.6-7.29) USD/kWh while it is (0.35-0.5) USD/kWh, (0.27-0.30) USD/kWh and 0.11 USD/kWh for PV power system, diesel generator power system and electricity grid respectively. Based on this, the use of wind power system as a standalone system is not recommended for Malaysia.
