Korean Electricity Market#8. Reference - Ulleung Island Microgrid
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
