Korea's Five Gencos to Merge: Scale Gains vs. Monopoly Risks
South Korea's government has decided to consolidate five state-owned power generators (Korea East-West Power, Korea Midwestern Power, Korea Western Power, Korea Southern Power, and Korea Southeastern Power) into a single entity called 'Korea Generation' after 25 years of operating separately.
The government has decided to merge five Gencos under Korea Electric Power Corporation—Korea South-East Power, Korea Midland Power, Korea Western Power, Korea Southern Power, and Korea East-West Power—into a single company tentatively called Korea Generation. This reverses course 25 years after the government split Korea Electric Power Corporation's generation division in 2001 to raise efficiency through competition.
The stated rationale for this merger is economies of scale. However, with the creation of a mega-sized public enterprise employing over 14,000 workers, there is concern that without accompanying organizational and workforce restructuring, the inefficiencies of five separate companies could simply be transferred into one massive organization.

The largest advantage of merging the five Gencos into one is the concentration of investment and workforce.
Currently, the five Gencos each execute roughly 50 billion won annually in research and development spending and 200 billion won in renewable energy project budgets. They pursue similar projects separately. Merging into one company would make it easier to pool funds and technical personnel to pursue offshore wind and large-scale renewable energy projects.

Korea's government is developing a major semiconductor cluster in the southwest region, with offshore wind projects positioned as a critical clean power source.
South Korea's K-GX (Korea Green Transformation) strategy aims to expand renewable energy capacity to 100GW by 2030, with offshore wind playing a key role alongside solar and emerging technologies.
Eight Korean companies including GS Entech, Doosan Enerbility, and Hanwha Ocean are establishing a full-cycle offshore wind supply chain spanning component production to installation vessel construction as part of the government's K-GX strategy.
President Lee Jae-myung called for expanded demonstration opportunities for domestically-developed wind turbines in the Southwest Offshore Wind project, emphasizing the need to reduce reliance on foreign technology.
South Korea's government has decided to consolidate five state-owned power generators (Korea East-West Power, Korea Midwestern Power, Korea Western Power, Korea Southern Power, and Korea Southeastern Power) into a single entity called 'Korea Generation' after 25 years of operating separately.
Korea's five state-owned generators become one in October 2027. They hold 14.0 GW of offshore wind, a third of the national pipeline. What the merger case rests on, and what it leaves unanswered.
