An experimental investigation was carried out to identify the difference between wind turbine power curves derived from hub height wind speed (HHWS) and rotor equivalent wind speed (REWS) at the Haengwon and Dongbok wind farms on Jeju Island. The terrains of the wind farms were analyzed according to International Electrotechnical Commission (IEC) 61400-12-1 2nd edition. The Haengwon wind farm was analyzed as a simple terrain, while the Dongbok wind farm was analyzed as a complex terrain that needed site calibration before power performance testing. Since the site calibration process for the operating wind farm was not possible, power performance testing was performed without site calibration. The power curves were derived using HHWS and REWS, and the annual energy productions (AEPs) were calculated by applying the Rayleigh wind speed distribution to the power curves. In addition, the normalized revenue by 1 MW for 20 years was calculated using the AEPs. As a result, the average HHWS and REWS at the Haengwon wind farm were 11.68 m/s and 11.64 m/s, while those at the Dongbok wind farm were 8.22 m/s and 8.18 m/s, respectively. The average relative error of the AEP at annual average wind speeds of 5to 11 m/s was 0.96 % for Haengwon wind farm and 1.68 % for the Dongbok wind farm. The average revenue difference at annual average wind speeds of 4 to 11m/s was 55 million Korean won for the Haengwon wind farm and 111 million Korean won for the Dongbok wind farm.
