Korea Net Metering

In 2005, South Korea introduced its net energy metering for grid-connected rooftop PV projects with a capacity size small than 5 kW. Generators with an excess electricity remaining after self-consumption can feed electricity into the grid and offset against their consumption of grid power. In return, customers receive credit that can be later used to meet demand above self-generated electricity. Unused retail credits can be carried over to subsequent months but cannot be sold.
