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
