The Government of Malaysia has set a striving target to achieve a higher usage of renewable energy (RE) in the energy mix which is currently around 2 of the country�s electricity. Yet, the government intends to increase this ratio up to 20 by the year 2025. Most of the renewable energy in Malaysia comes from hydropower and biomass sources. Meanwhile, numerous studies have been conducted to determine the feasibility of wind energy in Malaysia. Several locations were reported to be economically viable for wind energy development such as Kudat, Mersing, and Kuala Terengganu. This study presents and discusses the whole life cycle cost analysis of an offshore wind farm in Kudat, Malaysia and determines the cost drivers of offshore wind energy developments. It covers the wind data collection and analysis, breakdown of whole life cycle cost structure, and calculation of the levelized cost of energy (LCOE). Results showed that almost 67 of the total cost was incurred by the capital expenditure (CAPEX), and around 26 by operation and maintenance costs (OPEX), while decommissioning costs (DECOM) reached up to 7 of the whole life cycle costs. The LCOE was calculated and determined to be USD 127.58/MWh. © 2021 by the authors. Licensee MDPI, Basel, Switzerland.
