The Jeju Special Self-Governing Province announced the “Carbon-free Island Jeju by 2030" plan in 2012. Implementation of this plan will made Jeju Island the world's first carbon-free region by 2030. In this study, a model for calculating the cost of an electric power system for a carbon-free Jeju Island was designed and then used for simulates. Hourly wind data, the characteristics of the solar power plants, and the electricity demand from 2012 to 2017 were used as inputs for the simulations. The values of the electric energy sources for Jeju's minimum-cost electric-power system in 2030 were determined through simulations under the condition that the electric demand always be equal to the electric supply in electric energy supply system. The solar power, onshore wind power, offshore wind power and ESS (Energy Storage System) in 2030 are expected to be 800 MW, 300 MW, 1031 MW, and 200 MW, respectively. The total cost of the carbon-free Jeju power system was estimated at around $60.7 billion. In addition, the total cost of the power system was found to decrease under the condition that solar power increased.
