KEPCO Faces 19 Trillion Won Bond-Limit Shortfall as Tariff Debate Returns

Korea Electric Power Corp. is facing a potential 19.2 trillion won gap between its projected bond balance and its statutory issuance ceiling, intensifying pressure on policymakers to revisit electricity tariffs or extend emergency financing rules.

A temporary provision allowing the state-run utility to issue bonds worth up to five times the sum of its capital and reserves is scheduled to expire at the end of 2027. From 2028, the ceiling is due to return to twice that amount. The exemption was introduced after surging global energy prices following Russia’s invasion of Ukraine generated heavy losses at KEPCO.

Based on KEPCO’s 2026–2030 financial management plan, the National Assembly Budget Office estimates that the company’s capital and reserves will total 28.42 trillion won at the end of next year. That would place its standard bond ceiling at about 56.84 trillion won. Its outstanding bonds, however, are projected to reach roughly 76.05 trillion won, leaving an excess of approximately 19.21 trillion won if the temporary rule ends as planned.

KEPCO’s bond balance stood at 71.5 trillion won in the first half of this year. The company has struggled to reduce debt after residential and general electricity rates remained frozen for an extended period, partly because of inflation concerns. Higher liquefied natural gas prices linked to conflict in the Middle East could also interrupt its financial recovery.

The funding strain comes as KEPCO prepares for extensive investment in transmission and substation infrastructure. Its latest long-term grid plan calls for 72.8 trillion won of spending through 2038, an increase of 16.3 trillion won from the previous plan. Demand from semiconductor clusters, physical artificial intelligence projects and AI data centers could push required investment even higher.

An attempt to secure advance payments also failed. KEPCO recently asked Samsung Electronics and SK hynix to prepay about 25 trillion won in electricity charges covering five years, but both companies declined. A planned regional pricing system for industrial electricity may add another variable if lower rates outside the Seoul metropolitan area reduce power-sales revenue.

KEPCO President Kim Dong-cheol told a parliamentary audit on Oct. 19 that the government should discuss a minimum tariff increase because essential grid investment is rising rapidly. Analysts at Shinhan Securities said the utility would need either to repay the projected excess or secure equivalent capital, but no clear solution is currently available. They described another delay to restoration of the normal bond limit as the most realistic option.

The decision will require the government to balance household inflation concerns against KEPCO’s financial stability and the power infrastructure needed for Korea’s advanced industries.
