Micro Grid in Korea : Energy Self-Reliance Island
Objectives
Establishing self-reliance island for CO2 reduction, energy cost reduction and operation efficiency enhancement
Minimizing existing diesel generators by applying renewables with ESS
Supplying electricity with the price lower than diesel power generation cost
Area : A total of 62 islands to which KEPCO provides electricity
System Configuration :
Diesel Generation + Renewable Energy(Wind Turbine, Photovoltaic, etc.) + ESS
Power Purchase Agreement (PPA) between KEPCO and private companies
