Investor Relation

HVDC market has been oligopolistic by three major companies like ABB, Siemens, ALSTOM while progressing many HVDC projects all over the world. 


“HVDC market in the world

has been oligopolistic by three major companies

like ABB, Siemens, ALSTOM, alliance with ALSTOM

to secure HVDC technology competitiveness at its early stage,

Transfer of Competence via

joint execution of domestic HVDC projects”

Korea is currently trying to develop HVDC technology to reduce its cost and to penetrate into the overseas market. As a result, we have successfully localized production of DC submarine cable whereas we are still experiencing difficulties in development of core equipment such as control&protection system, valve, converter transformer. KEPCO decided to introduce HVDC technology from ALSTOM to secure necessary competencies to increase reliability and to penetrate into overseas market. KAPES has been established by mutual investment from KEPCO and ALSTOM taking business opportunities of KEPCO and technology of ALSTOM.

KAPES will secure the technology over all stages of design, engineering, manufacturing, test&commissioning as well as necessary performance record as required qualification to penetrate into overseas market. KAPES currently have 16 employees including 2 ALSTOM secondees.

KAPES organization is comprised of technical division(System team, Valve team, Control team) and operating division(Management Supporting team, Project Operating team, Procurement team) with three teams under each division.

Long Distance Transmission, Economical Solution to

link between Asynchronous Networks, Suitable

Solution for Renewable Energy Transmission,

Applied to link Jeju and Mainland, Anticipated for

Global Market  to grow up to 7.5 Trillion KRW by 2020


KAPES is planning to mainly focus on KEPCO Buk-Dangjin ~ Godeok HVDC project expected to be awarded at the end of 2013. This is the essential key
for KAPES to receive successful Transfer of Competence and to stabilize its operation. Moreover, it is the very first project for KAPES which has been

Power business field has been quantitatively growing. It is now in the era where qualitative growth is needed. It is time to secure high-valued
technologies required by global market corresponding to its trend. Particularly, renewable energy, HVDC, smart grid businesses should be the first priority as indefinite growth expected. KAPES will be the roll-out to take a leap out of limited domestic market to be a part taker of the global market of the power industries.
