Wind energy assessment for selected sites in Malaysia and the proposed feed-in-tariff rates

Abstract

Wind energy is still not recognized as eligible energy resource in Malaysian Renewable Energy Act 2011. There are only four technologies applicable for Feedin-Tariff (FiT) which are biomass, biogas, solar and small hydro. Thus, there is no Feed-in-Tariff (FiT) for the wind projects in Malaysia. This thesis presents the identification of Feed-in-Tariff (FiT) based on the Annual Energy Production (AEP) at every selected site: Kuala Terengganu, Mersing, Kudat and Langkawi Island. WindPRO and WAsP software are used for the energy simulation. The wind data are obtained from the Malaysian Meteorological Department (MMD) stations. The Pitch 22 kW wind turbine was selected for energy simulation due to its best capacity factor compared to the other type of wind turbines. Forty six different installed capacity wind farm in range 22 kW till 1.012 MW were simulated based on the 22 kW wind turbine, sites roughness condition and sites wind resources. The Feed-in-Tariff (FiT) is identified by Net Present Value (NPV) analysis, Payback Period (PBP) analysis and degression rate analysis. The result found that the proposed FiT rates are based on the value of NPV is 98.6% from the investment cost with payback period is 10 years. The best degression rate is 5% for every year.
