Both KEPCO and Ulleung-Island will receive benefits from Microgrid

• KEPCO 29% of generation cost

recovery

€15.8M of annual loss (as of 2013)

• Ulleung Island Upsurge of CO2 emission

from diesel plants and fossil-fuel vehicles

Delay of green island development

Expected BenefitsCurrent Issues

Microgrid Project with Korean Gov-ernment Support

(such as REC bonus)

• KEPCO Increase in generation cost

recovery rate and decrease in annual loss

Plants and distribution deferral by 20% of peak reduction

• Ulleung Island CO2 reduction: 4,771ton

: by renewables, EVs, etc

Boost of green tourism: Job creation, effect on production inducement
