Frankfurt (Germany), 6-9 June 2011

History 1898 : The first electric power company was founded 1961 : Three regional electric companies merged into a national electric Power company(KECO) 1982 : KECO was renamed as KEPCO, a wholly goverment-owned 2001 : KEPCO’s generation unit was spun off into 6 subsidiaries

As of 2010 Number of Customers : 223,488,239 Sales(kWh) : 434,160,228,034 10st Ranked in Utilities(Fortune) Asset(107.6 Billion USD, ranked 5st in KOREA) Credit Rating(A2 : Moody’s, A : S&P)

Business Model


Type A[Energy Shifting]

Type B[Power Smoothing]

Type C[PQ Compensation]

Type D[Intentional Islanding]

Stores energy in low load time, and Discharges in peak time by using Large capacity storage

Makes the generation power smooth by small capacity storage

Improves the PQ at PCC(Point of Common Connect); Voltage variation reduction, PQ improvement, etc

Supplies power to customers in isolated grid when in case of KEPCO lines’ outage

Connection Capacity (As-is)

Ⅳ. Distributed Resource Interconnection Rules Technical Criteria (To-be)

“DG can be interconnected to the grid if they meet the technical criteria”

“DG can not be interconnected to the grid if their capacity over the capacity rules”

RenewableEnergy

Power Smoothing

PQ Compensation

SR have no technical barrier for connection with grid

Exising rule and policy

Ⅴ. Policy for DG Positive Impacts on Grid Changed rule and policy

“The changed rules and policy lead to the positive impacts of DG”

“The Capacity Rules intend to alleviate the negative impacts of DG”

RenewableEnergy

Power Smoothing

PQ Compensation

SR can provide the ancillary service and also participate in

the electric market

(Smart Renewable Functions)

The existing rules and policy focus on the negative negative

impacts of DGimpacts of DG

☞ limit the connection capacity of DG

☞ hinder R&D activity and application

of new technologies

The changed rule intend to drive

the positive impacts of DGpositive impacts of DG

☞ Enlarge the connection capacity

☞ Utility have help form DG and also

DG create new benefits
